Configure php-fpm and nginx to run in low memory server

by

It was pain in the ass to have php-fpm and nginx together to serve php app, especially when you’re running on low-memory server, especially when you’re running cms like wordpress which basically heavy duty. I had a Centos server running with memory only 1024Mb (1Gb).

My web kept crushed every single time. And the problem stil remains, memory leak.

I don’t know what the root cause was. I still don’t know what that is but I think it’s something to do with php-fpm configuration or even nginx.

Just several days ago I had my blog up and running with wordpress in the same type of server, same OS (Centos) with the same memory (1Gb) and since I didn’t want to use apache for some reason, guess I had to get my nginx and php-fpm working together again.

I thought my web would be running very smoothly since the blog was still unlikely to receive much traffic. But I was wrong, somehow the memory was leaked again. My server only running with 1024Mb, but I thought It didn’t matter. The only way to get this problem mitigated is to tune up both the php-fpm and nginx configurations which I never liked this. But I need this, so let’s get this done.
