Logrotate with nginx

/path_to_accesslog/access.log {
    missingok
    notifempty
    size 100000k
    daily
    create 0644 www root
    postrotate
[ ! -f /etc/nginx/logs/nginx.pid ] || kill -USR1 `cat /etc/nginx/logs/nginx.pid`
    endscript
}

Explain:

missingok :  do not output error if logfile is missing
notifempty : do not rotate if logfile is empty
size             : Log file is rotated if it is  bigger than 100000KB
daily            : daily rotation
create 0644 www root : create new logfile with permission 644 where owner is www and group is root user.
postrotate
[ ! -f /etc/nginx/logs/nginx.pid ] || kill -USR1 `cat /etc/nginx/logs/nginx.pid`
    endscript

=> tells nginx reload the log files .

Finish!!!
