NGINX 配置
NGINX配置详解:http://blog.csdn.net/tjcyjd/article/details/50695922
Nginx主配置(默认虚拟主机)文件:/usr/local/nginx/conf/nginx.conf
添加的虚拟主机配置文件:/usr/local/nginx/conf/vhost/域名.conf
vim /usr/local/nginx/conf/nginx.conf
防止IP访问服务器 加在 http { } 里面 每个server{}都是写在http{}里面。
server
{
listen 80 default;
listen 82 default;
return 404;
}
vim /usr/local/nginx/conf/nginx.conf
(1)cpu有多少个核,就有几位数,1代表内核开启,0代表内核关闭
(2)worker_processes最多开启8个,8个以上性能就不会再提升了,而且稳定性会变的更低,因此8个进程够用了
参考:http://www.php230.com/set-worker-cpu-affinity-to-up-nginx-performance.html
user www www; worker_processes auto; //工作进程:数目。根据硬件调整,通常等于CPU数量或者2倍于CPU。 worker_cpu_affinity auto; error_log /home/wwwlogs/nginx_error.log crit; pid /usr/local/nginx/logs/nginx.pid; #Specifies the value for maximum file descriptors that can be opened by this process. worker_rlimit_nofile 51200; events { use epoll; worker_connections 51200;
//每个进程允许的最多连接数根据硬件调整,和前面工作进程配合起来用,尽量大,但是别把cpu跑到100%就行。每个进程允许的最多连接数,
理论上每台nginx服务器的最大连接数为。worker_processes*worker_connections
