Logrotate

If you want to split log files daily then you could use logrotate module for linux environments. I will tell how to make it.

• Firstly, we install logrotate module for system. yum update && yum install logrotate
• Logrotate configirations are in /etc/logrotate.conf
• Logrotate web server configirations are in /etc/logrotate.d

Note : I use nginx web server so i will make the configirations for nginx.

• Open the /etc/logrotate.d/nginx file with editor and then add the following commands in.

 /var/log/nginx/access.log {
    create 0640 nginx root
    daily
    rotate 10
    missingok
    dateext
    dateformat -%d-%m-%Y
    olddir /var/log/access
    notifempty
    compress
    delaycompress
}

The above commands provides that access log data will be wrote to daily files in /var/log/access, If you have not /var/log/access folder then you should create it with : mkdir /var/log/access

• Lastly you have to add a cron job and it should work daily. It is command:

logrotate -f /etc/logrotate.d/nginx

crontab -l | { cat; echo "59 23 * * * logrotate -f /etc/logrotate.d/nginx >> /dev/null 2>&1"; } | crontab -
