Nginx configuration file Configuration Items detailed description

Transferred from: http://www.cnblogs.com/xiaogangqq123/archive/2011/03/02/1969006.html

The following records the configuration file description of the Nginx server nginx.conf, and some of the comments are collected with the network.

The above is some basic configuration, the biggest advantage of using Nginx is load balancing

If you want to use load balancing, you can modify the configuration HTTP node as follows:

#设定http服务器, using its reverse proxy function to provide load balancing supportHTTP {#设定mime类型, the type is defined by the Mime.type fileInclude/etc/nginx/mime.types; Default_type Application/octet-stream;#设定日志格式Access_log/var/log/nginx/access.log;#省略上文有的一些配置节点# ..... #设定负载均衡的服务器列表Upstream Mysvr {#weigth参数表示权值, the higher the weight, the greater the chance of being assigned.Server192.168. 8. 1X:3128weight=5;#本机上的Squid开启3128端口Server192.168. 8. 2X: theweight=1;Server192.168. 8. 3X: theweight=6; } upstream MYSVR2 {#weigth参数表示权值, the higher the weight, the greater the chance of being assigned.Server192.168. 8. x: theweight=1;Server192.168. 8. x: theweight=6; }#第一个虚拟服务器Server{#侦听192.80 Port of 168.8.xListen the; server_name192.168. 8. x;#对aspx后缀的进行负载均衡请求Location ~. *\.aspx$ {root/root;#定义服务器的默认网站根目录位置IndexIndex. phpIndex. htmlIndex. htm;#定义首页索引文件的名称Proxy_pass http://mysvr; #请求转向mysvr defined list of servers#以下是一些反向代理的配置可删除.Proxy_redirect off;#后端的Web服务器可以通过X-forwarded-for Get the user real IPProxy_set_header Host $host;              Proxy_set_header X-real-ip $remote _addr;              Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for; Client_max_body_sizeTenM#允许客户端请求的最大单文件字节数Client_body_buffer_size -K#缓冲区代理缓冲用户端请求的最大字节数,Proxy_connect_timeout -;#nginx跟后端服务器连接超时时间 (proxy connection timed out)Proxy_send_timeout -;#后端服务器数据回传时间 (proxy send timeout)Proxy_read_timeout -;#连接成功后, back-end server response time (proxy receive timeout)Proxy_buffer_size4K#设置代理服务器 (nginx) buffer size for saving user header informationProxy_buffers4 +K#proxy_buffers缓冲区, the average page is below 32k, so setProxy_busy_buffers_size -K#高负荷下缓冲大小 (proxy_buffers*2)Proxy_temp_file_write_size -K#设定缓存文件夹大小, greater than this value, will be passed from the upstream server}         }    }

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the Nginx configuration file configuration items detailed description, including aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
