Configuration file description for Nginx server nginxconf

In this record the Nginx server nginx.conf configuration file description, some comments collected with the network.

Run user

User Www-data;

Start process, usually set to equal to the number of CPUs

Worker_processes 1;

Global error log and PID file

Error_log/var/log/nginx/error.log;
Pid/var/run/nginx.pid;

Operating mode and maximum number of connections

Events {
Use Epoll; One way in #epoll是多路复用IO (I/O multiplexing), but only for linux2.6 above the core, can greatly improve the performance of Nginx
Worker_connections; Maximum number of concurrent links #单个后台worker process processes
# multi_accept on;
}

Set up an HTTP server to provide load balancing support with its reverse proxy function

HTTP {
#设定mime类型, the type is defined by the Mime.type file

Default_type Application/octet-stream;
#设定日志格式

#sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，#必须设为 on,如果用来进行下载等应用磁盘IO重负载应用，可设置为 off，以平衡磁盘与网络I/O处理速度，降低系统的uptime.sendfile        on;#tcp_nopush     on;#连接超时时间#keepalive_timeout  0;keepalive_timeout  65;tcp_nodelay        on;#开启gzip压缩gzip  on;gzip_disable "MSIE [1-6]\.(?!.*SV1)";#设定请求缓冲client_header_buffer_size    1k;large_client_header_buffers  4 4k;include /etc/nginx/conf.d/*.conf;include /etc/nginx/sites-enabled/*;#设定负载均衡的服务器列表 upstream mysvr {#weigth参数表示权值，权值越高被分配到的几率越大#本机上的Squid开启3128端口server 192.168.8.1:3128 weight=5;server 192.168.8.2:80  weight=1;server 192.168.8.3:80  weight=6;}

server {

}

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:

Set up an HTTP server to provide load balancing support with its reverse proxy function

HTTP {
#设定mime类型, the type is defined by the Mime.type file
Include/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，权值越高被分配到的几率越大server 192.168.8.1x:3128 weight=5;#本机上的Squid开启3128端口server 192.168.8.2x:80  weight=1;server 192.168.8.3x:80  weight=6;}

Upstream MYSVR2 {
#weigth参数表示权值, the higher the weight, the greater the chance of being assigned.

server 192.168.8.x:80  weight=1;server 192.168.8.x:80  weight=6;}

#第一个虚拟服务器
server {
#侦听192.80 Port of 168.8.x
Listen 80;
server_name 192.168.8.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 index index.php index.html index.htm;      #定义首页索引文件的名称 Proxy_pass http://mysvr; #请求转向mysvr the server list #以下是一些反向代理的配置可删除 defined.

}

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