nginx的高性能参数配置

1)nginx.conf 里面的参数配置,假设服务器8核心(逻辑核心)

worker_processes 8;
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;
worker_rlimit_nofile 102400;
events
{
use epoll;
worker_connections 204800;
accept_mutex on;
}

2) /etc/rc.local

echo “ulimit -SHn 65535” >> /etc/rc.local

3)/etc/security/limits.conf

* soft nofile 655360
* hard nofile 655360

4) /etc/sysctl.conf

net.ipv4.ip_forward = 0
