Hello,

I have been researching the ability to limit a cpu usage amount to processes on a rhel server.

e.g.

php scripts can only consume 20% of the cpu. If it crosses that threshold the process will be terminated. As well as httpd processes, they are limited to a certain percentage of the cpu.

I have been looking up making changes to:

limits.conf
php.ini

Has anyone had to cross this bridge before? I can use some feedback on the correct approach to this.


Thanks,

Jaysunn

limits.conf only limit cpu in minutes or seconds.Take a look at nice, ulimit and renice command. There is no config option that can limit 20% php cpu usage. However, a perl or php scrip can monitor usage and kill process if CPU >= 20%.

Yes,

I am actually working on a perl script to do just that. Thank you very much for your reply.

I will be sure to post it when it is complete.
