2. Install the dependent package or you cannot compile the installation:

Yum groupinstall-y "Development tools" "Server Platform Development" "Desktop Platform Development" Yum Install-y pcre-d Evel

1) to create user Nginx and group Nginx, to implement the user Nginx run Nginx:

[[email protected] ~]# groupadd-r nginx    #nginx需要调用1000以下的端口, requires system users [[email protected] ~]# useradd-r-G nginx nginx[[e Mail protected] ~]# ID nginxuid=496 (nginx) gid=493 (nginx) groups=493

2) Unzip the installation package, install files can download the installation files in www.nginx.org:

3) Create the service script: Vim/etc/rc.d/init.d/nginx, write the following script: (explain the script, some paths are written according to the Configer option above)

#!/bin/sh## nginx-this script starts and stops the Nginx daemin## chkconfig:-15# Description:nginx is a HTTP (s) s Erver, HTTP (S) Reverse # Proxy and imap/pop3 proxy server# processname:nginx# config:/etc/nginx/nginx.conf# pidfile:/va r/run/nginx/nginx.pid# Source Function Library: /etc/rc.d/init.d/functions# Source Networking configuration: /etc/sysconfig/network# Check that networking are up.

Add permissions to script: chmod +x/etc/rc.d/init.d/nginx Add boot: chkconfig–add nginxchkconfig nginx on4) Add environment variable: # echo "path= $PATH:/usr/ Local/nginx/sbin ">>/etc/profile (Permanent entry into force) #export path= $PATH:/usr/local/nginx/sbin (currently in force)

5) test and start:

Before starting, pass the NGINX-T test

[Email protected] nginx-1.9.3]# nginx-tnginx:the configuration file/etc/nginx/nginx.conf syntax is Oknginx:configurat Ion file/etc/nginx/nginx.conf test is successful[[email protected] nginx-1.9.3]# service Nginx startstarting nginx:                                            [  OK  ]

3. Website visit Nginx, view the server IP address, the browser directly enter the corresponding IP address, nginx default port 80.
