My Server has the following Specs
CPU: 6 Cores Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz
RAM: 32 GB
I have a problem with nginx+php-fpm. They are taking too many resources for an unknown reason. Even if i restart the nginx + php-fpm the start up processes will use many resources.
My nginx Config is the following:
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
worker_rlimit_nofile 300000;
events {
worker_connections 6000;
use epoll;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
My php-fpm pool config is the following
[www]
user = nginx
group = nginx
listen = /var/run/php5-fpm.sock
listen.owner = nginx
listen.group = nginx
listen.allowed_clients = 127.0.0.1
pm = ondemand
pm.max_children = 1500;
pm.process_idle_timeout = 5;
chdir = /
security.limit_extensions = .php
I'm using on pm.ondemand since my website has to support many concurrent connections at the same time and i was unable to to it with dynamic/static.
I guess this isnt the problem because as i said earlier when i restart nginx+php-fpm at the same time, they are taking too much resources without any request.
