Nginx uses logrotate to split the log

System Environment

Ubuntu 14.04LTS
Nginx 1.4.7 Edit the Nginx file under Logrotate

$ Vim/etc/logrotate.d/nginx
/usr/local/nginx/logs/*.log {//log location
    su root list   //Use root permission  , if not used  may report permissions related to the issue following the mention
    daily//    run once a day
    Missingok  //If the log file is missing, do not error continue to perform the next
    rotate 7   // Log save 7 days
    dateext//File suffix is a date format, that is, after the cut file is: xxx.log-20131216.gz So, if commented out, cut out is by the number increment, that is said before xxx.log-1 this format
    Notifempty   //If it is an empty file, do not dump  the permissions of Create 0640 root/log file
    sharedscripts
    prerotate
        if [-d/etc/logrotate.d/httpd-prerotate]; then \
            run-parts/etc/logrotate.d/httpd-prerotate; \
        fi \
    endscript
    postrotate
        [-s/run/ Nginx.pid] && kill-usr1 ' cat/run/nginx.pid '
    endscript
}

The file with the date in the back is generated, which indicates success.
Test

$/usr/sbin/logrotate-f/etc/logrotate.d/nginx 
//If a file is generated indicates a successful configuration
