Christian's questions

I'm trying to redirect only static file requests from a particular directory prefix when they 404.

I've tried using try_files and it may well work still but it hasn't for me so far.

This is the scenario;

Request is for https://example.com/forums/uploads/file.jpg File 404's Redirect to https://cdn.example.com/file.jpg

It's the change in path that I'm finding tricky.

I don't think it's possible, but a check for a non 404 on the CDN would be great also.

Solution (Based on accepted answer);

location ~* /forums/uploads {
    try_files $uri @rewriteimages;
}
location @rewriteimages {
    rewrite ^/forums/uploads(.*)$ https://cdn.example.com$1 redirect;
}

Monit is reporting very low memory use that is not consistent with actual use.

If I look at Monit, under System I see "5.7% [918.0 MB]" though the real scenario is very different;

             total       used       free     shared    buffers     cached
Mem:         15947      14755       1191       1495        889      11508
-/+ buffers/cache:       2357      13590
Swap:         8191        113       8078

Memory use is actually around 90% and 14.7GB.

It reports similar low use for PHP-FPM at "5.0% [799.1 MB]".

Not sure what I can do to make it report the correct use?

Note that my db server reports correctly "83.4% [13.0 GB]".

EDIT

Just noticed this in release notes;

"Fixed: On 32-bit platforms with more then 4GB of RAM, Monit reported incorrect system and swap memory values (regression in Monit 5.16)."

Going to upgrade and see if it fixes it.

EDIT 2

Have upgraded to monit 5.17.1 and the problem persists.

A few weeks ago I noticed in the Google Webmaster tools that a few of my URL's were returning 502's.

One such URL is http://www.sau.com.au/forums/topic/437438-around-the-bay-wrap-up/

This URL returns the 502 for any desktop skin but works fine when on mobile (different skin)

Note that it returns the 502 very quickly, suggesting to me that it is not an execution or some form of timeout.

Besides a few more like this, all other URL's on the site are fine.

The only log entry to help at all is this one;

2015/06/29 09:33:39 [error] 19650#0: *4431763 upstream prematurely closed FastCGI stdout while reading response header from upstream, client: 94.228.34.203, server: sau.com.au, request: "GET /forums/topic/437438-around-the-bay-wrap-up/ HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/php-fpm.sock:", host: "www.sau.com.au", referrer: "http://www.sau.com.au/forums/forum/100-victoria/"

I have also restarted APC which didn't help. It had only 1.5% fragmentation.

I can't find any limit-reached entries. The server is specced quite high so PHP has a lot of memory, request sizes and also long timeouts.

I tried the following that I read about but no diff.

fastcgi_buffer_size 10240k;
fastcgi_buffers 4 10240k;

I'm reluctant to make any big changes because this is only on some pages. One thread suggested updating PHP to 5.5.

I dont know where to look now for further assistance. What should my next step be?

Some info;

nginx version: nginx/1.6.2
PHP 5.3.3 (fpm-fcgi) (built: Oct 30 2014 20:14:56)

UPDATE 1

PHP error log has nothing written to it. Error logging is enabled though;

php_admin_value[error_log] = /var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on

UPDATE 2

dmesg doesn't seem to be updating and there is no kernel.log;

-rw-r--r--   1 root   root       41179 Dec 18  2014 dmesg

RESOLVED

I was installing XDebug as proposed by @sa289 in this answer and to do so I needed to update from PHP 5.3 to PHP 5.5. I was hoping that would fix the issue on its own, but it didn't. So, I installed XDebug and added the zend_extension to php.ini, restarted PHP and voilà the 502's are gone. I commented out the zend extension again and the 502's returned. XDebug to the rescue. No firm grasp on the cause or true resolution but this is good enough for me.

I based my autoscaling AMI's on the Turnkey Linux nginx AMI from the marketplace.

I am now unable to select any of the newer generation instance types; for instance, my autoscaling uses m3.large type but I'd really like it to use the c3.xlarge type but every time I try to create a c3.xlarge instance with my AMI I get errors;

The instance configuration for this AWS Marketplace product is not supported.

My question is; Can I override this? I'm not using TKL support or any of their services, just the AMI.

If I can't override it, do I have any other options besides creating a brand new AMI from scratch to use?

So, I have been playing around with my auto scaling config and my Cloudwatch alarms to try and keep all my instances purring but not roaring.

I can't seem to get rid of a constant yoyo. CPU usage goes up, introduce an instance, CPU usage goes down, kill an instance. Rinse and repeat.

I'm currently basing my alarm on 3 x 1min intervals of average CPU >= 40%. Maybe I can base it on something else? CPU is a tricky one as when this graph is spiking (high) I can see some instances with idle CPU so the average is being raised by a single instance.

I'm finding some people are getting 502's when I'm getting 200's. Obviously I would like this to be consistent and stop this spiking all the times.

Thanks in advance.

EDIT 1: I have adjusted the Cloudwatch metric to be 20% cpu over 2 mins and also found an nginx error that may also have attributed to some additional load. Current graph looks like the below.

EDIT 2: Monitoring on load is so much better. See below for the load alarm. I'm getting alerts far less frequently and everything is running much nicer.

This is what I'm running in cron every minute;

/usr/local/bin/aws cloudwatch put-metric-data --namespace="NS" --metric-name="GroupLoad" --value `cat /proc/loadavg | awk '{print $1}'` --dimensions AutoScalingWebGroup=NS-WebGroup

I have a fairly hefty Dell machine with dual quad-core cpus and 32GB memory.

On that machine I host a pretty busy forum, but the one machine does everything; web, cache, db, sphinx, etc. I also have a full-system, downtime-less backup done nightly.

This all costs me a smidge under $800 p/m (Australian prices are higher) and I don't really trust the backups.

As an experiment I set up the following;

• ELB with Auto scale rules (add new instance after 2 mins of 20%+ CPU, drop instance after 5 mins under 20%. Max 5 instances)
• Two EC2 instances (m3.large) across availability zones.
• One m3.medium for NFS (And will add cache and sphinx to this) - This just stores user uploads and it is served through Cloud Front.
• One db.r3.large RDS instance with my my.cnf copied to it as best I could (I'm not a db expert, my conf follows me everywhere)

In its current state its approx $600 p/m and worst case scenario (5 web instances) it comes in at roughly $1k.

It seems very, very good.

Last time I tried EC2 with my site it kept falling over at busy periods due to a lack of connection support on the single instances, so this time I kept the instances smaller and put the ELB in front. Apache Bench (-n 1000 -c 100) from my machine seems to go well with 8+ requests per second and 50% of requests under 11799ms (100% under 17763ms.)

What am I missing? This all seems too good to be true. I can have scheduled snapshots of my db done whenever I want, I can have as many machines as I want behind the ELB and in its current (2 instances) state I reckon it would be fine for 90% of the day.

Please provide feedback on this, I'm not a systems guy, I just love AWS stuff and my site seems perfect for AWS based hosting.

Thanks.

I have used a TKL AMI on an EC2 instance to quickly create a NGINX / PHP box. Details of the image are on the Amazon marketplace.

It mostly works just as I'd expect it to except for a small caveat - I don't seem to have any php-fpm conf available to me. I may or may not have misunderstood what I'd be getting on the box and I'm reluctant to install anything else as I'm trying to keep it as vanilla as possible (for various reasons.)

I have a typical nginx conf which passes php back to fcgi and I have a typical PHP (not fpm) config in a typical php.ini and associated modules (xcache, pdo, etc.)

server {
  listen 0.0.0.0:80;
  root /var/www/current/app/;
  index index.php;

  include /etc/nginx/include/php;
  try_files $uri $uri/ /forums/index.php?q=$uri;
}

The /etc/nginx/include/php is very simple;

include /etc/nginx/fastcgi_params;

location ~ \.php$ {
  # http://forum.nginx.org/read.php?2,88845,page=3
  try_files $uri =404;

  fastcgi_pass unix:/var/run/nginx/php-fastcgi.sock;
  fastcgi_index index.php;
}

As is the /etc/nginx/fastcgi_params;

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

PHP is running as a service, so its got something running.

I have no pool config. No children / max requests etc - nothing. It works in that it serves pages, but it falls over when it gets too many connections (even before load is .5.)

What am I missing? Is FCGI not the same as FPM? Do I need to install something else in order to increase available workers and requests?

UPDATE: dpkg -l php5-fpm shows no package;

un php5-fpm <none>

We run a large forum with lots of reads and writes, particularly to the posts and topics tables which are both innodb.

Last week I started doing 12 hourly backups with innobackupex because mysqldump just takes forever (7+ million rows in posts table.) It seems that something doesn't like these backups because I have a recurring problem every other day.

The symptoms;

The front page of the site starts throwing errors
The logs start showing errors like Error: 126 - Incorrect key file for table '/tmp/mysql/#sql_4e87_14.MYI'; try to repair it
The /tmp/ dir fills up and we start getting Error: 1030 - Got error 28 from storage engine in the logs.

The only way to fix is to optimize table on each of the posts and topics tables.

I'm trying all I can to stop MySQL using disks for temp tables, but I'd have more problems than this if it used all my memory also.

My my.cnf is here; https://gist.github.com/cbiggins/0aa26f6defb7a14541d7

The box has 32GB memory and I don't come near that usually. Currently at 15GB use.

Thanks in advance.

Update 1: Despite the conf looking like there is replication, there isn't. This is a stand alone instance.

Update 2: Having now not done backups for more than 24hrs, the problem has just occurred again. So this is not the result of the backups.

Update 3: I have given MySQL 20gb of temp space now using tmpfs. Instructions here. Going to watch for the next little while and see how it goes.

Update 4: I found a killer query! 13 seconds and 2.3 million rows examined. Do this 20 times concurrently and I was filling up my new 20GB temp dir pretty quickly. I've disabled the block that was using this query and provided some feedback to the maintainer.

I've decided to get a super cheap dedicated server to replicate to to run backups from. Hopefully we can see my uptime climb again. :)

We have varnish sitting in front of our site and it is imperative that we cache as much as possible.

Recently we decided to ditch GeoIP redirection for interstate content for a more traditional 'choose your location' page. This page sets a cookie for their 'default' location and the desired outcome would be to have varnish read this cookie and redirect when at '/' only.

This functionality (while a little hacky) is supposed to be supported in varnish, but we've been unsuccessful in getting it to work. Should it work? Are we doing anything we shouldn't be?

Next to having an uncached static HTML page, what are our other options here? Can we have something other than varnish sit in front of just that page?

When we deployed the change without varnish caching it, we had massive performance issues as the site is built on Drupal and had to bootstrap every load.

If it is established that Varnish should do what we want, I'll add some vcl config to this question.

EDIT It looks like the best option is going to be to get varnish to not cache '/' and handle the cookie-based redirection in Apache.

RewriteCond %{REQUEST_URI} ^/?$
RewriteCond %{HTTP_COOKIE} cookie_name=([^;]+)
RewriteRule .* http://site/%1 [R=301,L]

Seems to do what we need.

I'm currently using NGINX with FastCGI and PHP 5.4 on the production server.

Lately we've been getting mass CPU usage spikes and I'd like to spend a few days using Apache and mod_php again to see if the problem might be isolated to NGINX/FCGI.

The server is new, conf copied from previous server.

The problem is, I don't seem to have mod_php installed and can't find it in any repos. I have searched and searched but the only info I can find is how to build PHP and Apache from source.

Granted, its been a few years since I have installed Apache/PHP etc from Yum, but surely CentOS 5.9 should have a package?

Thanks.

EDIT: Additional info;

If I try to install any php component via yum (php-xcache-admin or php-pdo etc) I get a heap of dependency errors.

libphp5.so is not on the box. updatedb && locate gives me nothing.

Recently I switched to NGINX/PHP-FPM to run my forums.

The majority of the time, the site runs beautifully, seriously quick and I'm really happy with it. Its on a 13 core/30+GB memory instance with AWS, so ample resources (was on 8 core, 16GB before with Apache.)

So, what happens is, the majority of the time we have 6 or 7 PHP-FPM processes and all is well with the world;

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
27676 apache    20   0  499m  34m  19m R 49.2  0.1   0:06.33 php-fpm
27669 apache    20   0  508m  48m  24m R 48.2  0.1   0:10.84 php-fpm
27661 apache    20   0  534m  75m  26m R 45.9  0.2   0:16.18 php-fpm
27671 apache    20   0  531m  69m  21m R 43.9  0.2   0:09.85 php-fpm
27672 apache    20   0  501m  41m  23m R 32.9  0.1   0:09.18 php-fpm
27702 apache    20   0  508m  40m  16m R 23.6  0.1   0:00.94 php-fpm

Well, kinda well. Lots of CPU used but theres only a few of them, so its kinda ok.

Then, seemingly out of nowhere, I spawn a bunch of processes (last time we had 52) and each one is using 8% CPU. You don't need to be good at this to know that 52 * 8 is A LOT.

Now, I have max_children set to 40 now (it was 50.)

pm.max_children = 40
pm.start_servers = 4
pm.min_spare_servers = 2
pm.max_spare_servers = 6
pm.max_requests = 100

Memory limit in php.ini is 128mb.

So, I understand why I get so many processes - thats fine, I have them configured. What I'm curious about is, if we have 8% cpu per process - is that too much? And, maybe my processes are staying alive too long?

As I write this, its 7:08PM - so the children processes have been running for 2 minutes and have probably served a lot in that time (Theres 700 people on the forums atm.)

So - super keen to hear advice/criticism/opinions. I've had so much downtime lately I'm verging on setting up Apache again and I'd love to stick with this.

Thanks in advance.

EDIT
This is the Bitnami graph showing the spikes and how quickly they occur (this is 24h)

EDIT #2
nginx.conf can be found here.

EDIT #3
I bumped my numbers up. Its looking good but still makes me a little nervous.

pm.max_children = 100
pm.start_servers = 25
pm.min_spare_servers = 25
pm.max_spare_servers = 50
pm.max_requests = 500

EDIT #4
So, I've had a few more downtimes and I've setup Splunk and New Relic to help me monitor what is going on. It seems that there is no CPU waiting time and I still have free memory.

Any help would be greatly appreciated, thanks.

So a few times now I've been caught out by clients receiving mail sent from the development server because I didn't sanitize the db. So, as an extra safe option, I'd like to ensure that all mail sent from my dev machine is either rejected based on domain or forwarded to myself.

I found a few questions that do a little of what I require;

Postfix on development server, allow mail to be sent to only one domain - This looks good and is what I have implemented so far, but the comment on the first answer is correct. Mail sent through Sendmail does not seem to use this setting.

postfix: catch outgoing mail and redirect - THis looked ok, but updating the transport did not do squat for me.

I also looked at address rewriting http://www.postfix.org/ADDRESS_REWRITING_README.html and read this blog post http://rene.bz/redirect-all-outgoing-email-single-account-postfix/

I am testing this by calling sendmail on the command line with the -t param like so;

sendmail -t < mail

where the contents of 'mail' are

Date: Tue Oct 11 11:25:22 2011 
To: [email protected] 
Subject: test 
From: [email protected]
test

I have been changing the address to be my gmail address and the example.com address. I'm wanting all mail to go to another (work) domain.

So far, I have seen no restrictions come into effect.

/etc/postfix/transport looks like this;

example.com :
.example.com :
* :discard

I have added these lines to main.cf

smtpd_recipient_restrictions = hash:/etc/postfix/my_access, reject
transport_maps = hash:/etc/postfix/transport

Please also note I am using the Postfix bundled with MAMP and have been editing main.cf through MAMP - File > Edit Template > main.cf

My current MySQL backup scenario is to replicate our db to a second server and run mysqldump on that server to remove any downtime from table or row locking. This is working well but costs $150 per month for the second server (Australian hosting is a lot more expensive than US.)

I read a lot of questions on here about this, most people need help with the scheduled backups and whatnot which is not what I need. I need to mysqldump (preferably every 4hrs) with no downtime. The db is ~7GB uncompressed, so the mysqldump can take some time depending on the server.

I have considered replicating to the same machine, but I didnt want the slave to eat into much needed memory. I'm not sure I can constrain memory usage on a per db basis? Either way, this will put load on the server while its dumping the db.

I just read this http://www.zmanda.com/quick-mysql-backup.html and it looks good, $300 per year is ok, that saves me a lot.

Unfortunately I can't replicate to Amazon's RDS but I could replicate to a micro RC2 instance but the replication would take place over-net and the ping is ~220ms.

I saw a few people on here talking about LVM snapshots which might be a good option. I dont know a great deal about this option tho.

Opinions would be greatly appreciated.

I recently moved my site to a new server (Apache 2, PHP5, MySQL5). The site is an Invision based forum. Every few posts / topics it just hangs. The data has been written because if you stop and reload, the post / thread is there. I thought it was a write issue initially, but nope. The data is written but the page load never completes. It doesn't leave the page where the data has been input.

What's the best way to troubleshoot this issue? The only thing I have done recently is reduce my MySQL timeouts, but I can't see that being an issue as the values are still big enough and there are no mentions of timeouts in the MySQL log. For the record there is nothing in PHP's error log either.

EDIT: I checked my server-status. It all looked ok, but I have a suspicion I was hitting my ServerLimit, so I doubled that. Also enabled my Keepalives. Will keep an eye on it.

EDIT 2: It's now been a few days and this is still occuring. I have more info though;

1. Apache is throwing seg faults, but enabling core dumps does not produce them.
2. I have tried disabling the modules in apache but it just stops things from working.
3. I fear it may actually be DNS related. If I watch Live Headers in Firefox, absolutely nothing happens during this 'hanging' period. After that, the responses come back fairly promptly.

UPDATE (05/04): I built the latest versions of Apache and PHP from source, no luck. I then removed those and used the remi repo to update all my packages to the latest stable. Segfaults seem to have stopped, but the hanging is continuing.

ini's are at:

• www.skylinesaustralia.com/php.ini
• www.skylinesaustralia.com/my.cnf
• www.skylinesaustralia.com/httpd.conf

UPDATE - SOLVED! - The issue was having a gigantic query cache size in MySQL. It was 2GB, changing it to 64M sorted it.

I am having to tune a client's MySQL server on a Windows machine but I only have access to the MySQL cli and some MySQLAdmin cli functions. I can't see how I can mysql-bench either because it needs to run on the same server as MySQL.

Is there a way I can benchmark or tune MySQL without having access to the OS? The Sysadmin who manages the server has told me just to send him any config changes and he will apply them but that will take forever going back and forth and I don't even know where the changes need to be made as I can't see anything on the system.

Anybody else had an issue like this?

Thanks.

We have some clients that send mail through our mail server. To batch send the mail, we have all mail on specific port (in this case 1025) forwarded to an accept script which saves the details in MySQL for batch processing. When I test this, it works perfectly, when the client tests, it works perfectly, however, when they send out from their Unica system, it looks like the mail goes straight past the script and into the mail stream. Is this possible?

Here are the lines from master.cf

000.000.000.000:1025 inet n      -       -       -       0       smtpd
        -o mynetworks=hash:/etc/postfix/injector/networks
        -o content_filter=clientid:
        -o syslog_name=clientid
        -o smtpd_timeout=1800s

clientid  unix   -       n       n       -       0       pipe
        flags=q user=filter argv=/var/injector/inject.php clntid

Any help would be much appreciated!

Thanks!

I have been given the task of updating the certificate for one of our clients on their server. Problem is, not only have I never done this before, but the process involved on all the sites I have read seems to not work for me.

Firstly, I never supplied my client with a key file before they got the new certificate, I was under the impression they needed that to generate it.

Secondly, the only other certificate file on the server is a generic looking one from Verisign, not domain specific like the new one I have been sent.

Lastly, the one I have been sent is a .cer file which is apparently as good as a .crt file but its making me more suspicious that its the wrong certificate.

My ssl.conf that refers to the certificates is like so;

SSLCertificateFile /etc/httpd/ssl/ssl.cert.pem
SSLCertificateKeyFile /etc/httpd/ssl/ssl.key
SSLCACertificateFile /etc/httpd/ssl/ca.crt <<< This is the verisign one

So, basically, I have a .cer file, a conf and a server and none of it seems right to me. I'd really love any help.

Thanks,

Christian

My local Ubuntu 7.10 dev server was unresponsive the other day so I rebooted it and now I can't boot into it.

I can boot into the Live CD and mount my hdd so I can have a look at the logs and what not. /var/log/messages has a lot of entries like this;

jun 9 09:32:55 mccoy -- MARK --

Then it has a few like this;

jun 9 09:15:30 mccoy kernel [92923832.32322332] res 09 90 989 78 67 56 Emask 0x2 (HSM Violation) [Not exact numbers]

When I boot, I get to a busybox shell after a message saying /dev/md2 doesn't exist.

I would be really appreciative for any help, this box runs a few things for the office and they're all down atm.

So I stuffed an upgrade of debian, both upgrade and dist-upgrade. I am more used to yum but thats no excuse.

Now things are being silly. The majority of things work, however, my bugzilla install fails. On loading bugzilla I get a 500 error and this is logged in the error.log;

Also, when I run checksetup.pl from Bugzilla, it seems to end prematurely;

Checking user setup ...

Precompiling templates ...
Not a subroutine reference at /usr/share/perl5/Bugzilla/Template.pm line 59.
Compilation failed in require at /usr/share/bugzilla/lib/checksetup.pl line 1291

I have reinstalled both perl and perl-base;

apt-get install --reinstall perl-base
apt-get install --reinstall perl

And have had no success.

Any help would be muchly appreciated.

Also, this site is becoming a lifesaver for a systems-noob like myself and I am really thankful to all the help I get.
