Nginx配置文件詳解

#user  nobody;    登陸用戶

worker_processes  1;   nginx開啓的進程數，通常開啓一個就足夠，多開幾個work進程，能夠減小機器io帶來的影響，在通常狀況下

開啓4個或者8個，多開無心

 

#error_log  logs/error.log;  錯誤日誌目錄

#error_log  logs/error.log  notice;

#error_log  logs/error.log  info;

 

#pid        logs/nginx.pid;   記錄nginx pid文件的參數

 

 

events {  每一個work進程能夠處理的鏈接數 併發鏈接數

    worker_connections  1024;  若是網站訪問量過大，已經超過1024併發數，那麼就要修改worker_connecions，這個植越大

併發數也就大，按照實際狀況決定，不能設置過多，不然會形成IO負載量過大

}

 

 

http {

    include       mime.types;  爲文件類型定義文件

    #keepalive_timeout  0;  保持鏈接的超時時間

    keepalive_timeout  65;

 

    #gzip  on; 是否採用壓縮
