My ecommerce site runs using a cluster of Apache web server. The cluster is behind nginx load balancer. I want to merge backend Apache web server log files for statistics purpose. How do I mere web server log files under Linux / UNIX like operating systems using cron jobs?
The cron and at services are used to allow commands to be executed at a later time. How do I restrict them to selected users such as root, opt1, opt2 and so on? How do I make sure user php can run php script but cannot modify or install a new job?
I am on Red Hat Enterprise Linux 5.x server. Is there is an easy way to run script or command at boot time after fresh reboot command?
ow do I add cron job under Linux or UNIX like operating system?
