webjay's questions

I have the following piece of magic in our Nginx configuration:

location /uploads {
  alias /mnt/macchina;
  location ~ ^/uploads/ {
    try_files $uri @rewrite;
  }
}

location @rewrite {
  rewrite ^/(.*)$ /index.php?q=$1;
}

It works, but doesn't look like poetry to me, so I'm thinking there might be a simpler approach.

The goal is that for /uploads/ Nginx should see root as /mnt/macchina and try_files at $uri or goto @rewrite where it should still see root as /mnt/macchina.

Is there a better way?

I am trying to add behavior for certain file types, but because my content isn't in the same folder, I hit a problem where the location match causes Nginx to look for content in the wrong folder.

With the following, a request for /wp-content/themes/ryu/fonts/ClearSans-Regular.woff makes nginx look for the file at /opt/wordpress/wp-content/themes/ryu/fonts/ClearSans-Regular.woff whereas if I comment the location ~* \.(ogg|ogv|svg|svgz|eot... part, Nginx looks for content in the right place.

Any clue how I can achieve this?

server {
  listen *:80;

  root /opt/wordpress;

  location ~* \.(eot|ttf|woff)$ {
    add_header Access-Control-Allow-Origin *;
  }

  location ~* \.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
    access_log off;
    log_not_found off;
    expires max;
  }

  location /wp-content/ {
    alias /opt/wp-content/;
    try_files $uri =404;
  }

  location / {
    alias /opt/public/;
    expires 1d;
    index index.html;
    try_files $uri @wpsupercache;
  }

}

Neo4j says I can install Neo4j via Maven by adding it to my build:

<dependency>
 <groupId>org.neo4j</groupId>
 <artifactId>neo4j</artifactId>
 <version>1.8.1</version>
</dependency>

But do I need a build? If so, what should my pom.xml look like?

I tried with this:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.webcom.app</groupId>
  <artifactId>webcom</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>webcom</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
        <dependency>
            <groupId>org.neo4j</groupId>
        <artifactId>neo4j</artifactId>
        <version>1.9.M04</version>
    </dependency>
  </dependencies>
</project>

But then I end up with:

[ERROR] Unable to locate the Javac Compiler in:

I have installed sun-jdk6-6.0.26 and set JAVA_HOME to /opt/local/java/sun6.

I'm trying to monitor uSWGI via Nagios, but according to uWSGI I have specified an invalid socket.

The socket path I got from the JSON config file which also says chmod-socket: 666 so I have a hunch that the problem is permission based. The socket file is owned by www-data who I don't want to tinker with, so any other ways?

uwsgi --socket=/tmp/app.sock --nagios
detected binary path: /usr/local/bin/uwsgi
UWSGI UNKNOWN: you have specified an invalid socket

ls -l /tmp/app.sock
srw-rw-rw- 1 www-data www-data 0 2012-10-26 17:00 /tmp/app.sock

I've setup mod_pagespeed and it seems to work fine, but only when I reload a page. Minutes later the optimization is gone.

Here's a static site where full optimization is only done when you reload the page: twitterbogen.dk

On the first load the CSS files have no .pagespeed. in them. If you reload they do. Any idea why?

Here's my Apache Server Information.

And here's my mod_pagespeed configuration:

ModPagespeed on
AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html
ModPagespeedFileCachePath            "/var/www/mod_pagespeed/cache/"
ModPagespeedGeneratedFilePrefix      "/var/www/mod_pagespeed/files/"
ModPagespeedEnableFilters rewrite_javascript,rewrite_css
ModPagespeedEnableFilters collapse_whitespace,elide_attributes
ModPagespeedEnableFilters extend_cache,combine_css,move_css_above_scripts,move_css_to_head,inline_css,inline_import_to_link,flatten_css_imports,inline_javascript,outline_javascript,rewrite_style_attributes,rewrite_images,sprite_images

Would it be possible on a Linux box to show a browser window with only the content window, meaning no border around it, neither menu bars etc?

We need this for a big concert screen where a client program runs in the background. In front of that window we need to show a webpage, and it must look like the two programs are as one.

In php-fpm.conf I have:

rlimit_files = 8192

My server is a 1G SmartMachine from Joyent, meaning it is a Solaris with 1GB memory.

My problem is that on high load I get errors like this:

Warning (2): touch() [function.touch]: Unable to create file app/tmp/cache/persistent/cake_core_users_da because Too many open files in [cake/libs/file.php, line 125]

Is my rlimit_files too low, and if so how high should I set it?
