NGINX 配置

 NGINX配置詳解:http://blog.csdn.net/tjcyjd/article/details/50695922

Nginx主配置(預設虛拟主機)檔案：/usr/local/nginx/conf/nginx.conf

添加的虛拟主機配置檔案：/usr/local/nginx/conf/vhost/域名.conf

vim /usr/local/nginx/conf/nginx.conf

防止IP通路伺服器   加在 http { } 裡面     每個server｛｝都是寫在http{}裡面。

server

{

listen 80 default;

listen 82 default;

return 404;

}

（1）cpu有多少個核，就有幾位數，1代表核心開啟，0代表核心關閉

（2）worker_processes最多開啟8個，8個以上性能就不會再提升了，而且穩定性會變的更低，是以8個程序夠用了

參考：http://www.php230.com/set-worker-cpu-affinity-to-up-nginx-performance.html

user  www www;

worker_processes auto; //工作程序：數目。根據硬體調整，通常等于CPU數量或者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;  
       //每個程序允許的最多連接配接數根據硬體調整，和前面工作程序配合起來用，盡量大，但是别把cpu跑到100%就行。每個程序允許的最多連接配接數，
         理論上每台nginx伺服器的最大連接配接數為。worker_processes*worker_connections
