HVNSweeting's questions

Since 2.3, OpenLDAP uses a configuration engine called slapd-config. They said that use it make all LDAP configuration can be changed on fly.

This is the header of /etc/ldap/slapd.d/cn=config.ldif:

# AUTO-GENERATED FILE - DO NOT EDIT!! Use ldapmodify.

I've changed data in it and some other files which have that header, after restarting slapd, my changes took effects.

Is there anything else happen if I change those files manually? If I don't need 'change on fly', should I edit those file manually instead of using ldapmodify? Which application generated those files, and when?

NOTE: I'm using openldap-2.4.28 on Ubuntu 12.04

I've set up and run a RAILS app (graylog2), and the below config made it work for root location:

server {
    server_name www.mydomain.com;

    location / {
        gzip off;
        uwsgi_modifier1 7;
        include uwsgi_params;
        uwsgi_pass 127.0.0.1:3033;
    }
}

but I want to place my app in a path, ex: /graylog2

I changed my config, added uwsgi_param SCRIPT_NAME /graylog2 but it did not work.

server {

    server_name www.mydomain.com;

    root /opt/graylog2-web-interface/public/;
    location /graylog2 {
        gzip off;
        include uwsgi_params;
        uwsgi_param SCRIPT_NAME /graylog2;
        uwsgi_modifier1 7;
        uwsgi_pass graylog2;
    }

    location / {
        autoindex on;
    }
}

I'm using Ubuntu 12.04.1 LTS, nginx/1.1.19 with latest uwsgi compiled from git

Nginx access.log

127.0.0.1 - - [16/Mar/2013:12:26:31 +0700] "GET /graylog2/ HTTP/1.1" 404 609 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0"

No nginx error.log

uwsgi.log

[pid: 2321|app: 0|req: 15/25] 127.0.0.1 () {42 vars in 963 bytes} [Sat Mar 16 12:24:04 2013] GET /graylog2/ => generated 609 bytes in 31 msecs (HTTP/1.1 404) 7 headers in 237 bytes (0 switches on core 0)

What is the right way to config nginx + uwsgi for my set up?

I'm using:

root@u1210: /etc () # lsb_release -d
Description:    Ubuntu 12.10
root@u1210: /etc () # dpkg -l | grep rsyslog
ii  rsyslog                                   5.8.6-1ubuntu9                                    amd64        reliable system and kernel logging daemon

Today, I tried to read log from nginx log file but got this error:

Mar 11 17:34:18 u1210 kernel: imklog 5.8.6, log source = /proc/kmsg started.
Mar 11 17:34:18 u1210 rsyslogd: [origin software="rsyslogd" swVersion="5.8.6" x-pid="9742" x-info="http://www.rsyslog.com"] start

Mar 11 17:34:18 u1210 rsyslogd-3003: invalid or yet-unknown config file command - have you forgotten to load a module? [try http://www.rsyslog.com/e/3003 ]
Mar 11 17:34:18 u1210 rsyslogd: the last error occured in /etc/rsyslog.conf, line 68:"$InputFilePollingInterval 10"
Mar 11 17:34:18 u1210 rsyslogd-2124: CONFIG ERROR: could not interpret master config file '/etc/rsyslog.conf'. [try http://www.rsyslog.com/e/2124 ]

check config version that rsyslog using:

root@u1210: /etc () # ps -ef | grep rsyslog
syslog   18934     1  0 17:42 ?        00:00:00 rsyslogd -c5

I 've just used default config, addition below lines:

$ModLoad imfile

$InputFileName /var/log/nginx/access.log
$InputFileTag nginx:
$InputFileStateFile nginxxxx
$InputFileSeverity error
$InputFileFacility local7
$InputRunFileMonitor
$InputFilePollingInterval 10

here is config file: http://pastebin.com/8RnHXaDd

nginx log file is exist:

root@u1210: ~ () # ls -l /var/log/nginx/access.log
-rw-r----- 1 www-data adm 730040 Mar 11 17:49 /var/log/nginx/access.log

I see that rsyslog is default on ubuntu, debian, fedora and many other distro. First, I think that this 5.8.6 is too old so it does not provide text file input function, but after google around, same thing can done from 3.X.

What I'm doing wrong here?

addition question: I tried syslog-ng, the config file is very nice, it work nice on this function. But google around, it seem is not used widely as rsyslog. There no good comparison about them (almost are out dated). Which do you suggest, syslog-ng or rsyslog? (I use Ubuntu/Debian)

Thanks!
