In Nginx, log files are rotated using the nginx -s reopen command. This command causes Nginx to close and reopen its log files. When used in conjunction with a log rotation tool such as logrotate, the log files can be rotated on a regular schedule.

To set up log rotation for Nginx logs, you can use the following steps:

Install the logrotate tool on your system if it is not already installed.
Create a configuration file for logrotate in /etc/logrotate.d/nginx with the following content:

/var/log/nginx/*.log {
  daily
  missingok
  rotate 7
  compress
  delaycompress
  notifempty
  create 640 nginx adm
  sharedscripts
  postrotate
    [ -f /var/run/nginx.pid ] && kill -USR1 `cat /var/run/nginx.pid`
  endscript
}

This configuration will rotate the Nginx logs daily, keep 7 days worth of logs, compress rotated logs, and send a signal to Nginx to close and reopen its log files after the rotation.

Run the logrotate command to test the configuration and rotate the logs.

sudo logrotate -v /etc/logrotate.d/nginx

If the configuration and rotation are successful, you can set up a cron job to run the logrotate command on a regular schedule.
For example, to run logrotate daily, you can add the following line to the /etc/crontab file:

0 0 * * * root /usr/sbin/logrotate /etc/logrotate.d/nginx

This will run logrotate daily at midnight and rotate the Nginx logs according to the configuration in /etc/logrotate.d/nginx.
