nginx access log retention

Centmin Mod Log Rotation

Centmin Mod should be auto log rotating your access and error logs via logrotate.

You can modify how long you retain your nginx logs before the logs are rotated by logrtate at /etc/logrotate.d/nginx. Below examples rotate logs daily or whenever they hit 500MB in size, keeping the last 10 logs (rotate 10)

Centmin Mod 123.09beta01's nginx log rotate would have the following log rotate config file /etc/logrotate.d/nginx contents if you server has more than 1153433 bytes of memory and more than 10485760 bytes of disk free space in /var partition

Code (Text):

/var/log/nginx/*.log /usr/local/nginx/logs/*.log /home/nginx/domains/*/log/*.log {
        daily
        dateext
        missingok
        rotate 10
        compress
        delaycompress
        notifempty
        postrotate
        /bin/kill -SIGUSR1 $(cat /usr/local/nginx/logs/nginx.pid 2>/dev/null) 2>/dev/null || true
        endscript          
}

If you server has less than 1153433 bytes of memory and less than 10485760 bytes of disk free space in /var partition

Code (Text):

/var/log/nginx/*.log /usr/local/nginx/logs/*.log /home/nginx/domains/*/log/*.log {
        daily
        dateext
        missingok
        rotate 10
        maxsize 500M
        compress
        delaycompress
        notifempty
        postrotate
        /bin/kill -SIGUSR1 $(cat /usr/local/nginx/logs/nginx.pid 2>/dev/null) 2>/dev/null || true
        endscript          
}

You can do a debug run of logrotate to see what happens when logrortate is meant to rotate your logs using SSH command

Code (Text):

logrotate -d /etc/logrotate.d/nginx
