1、准备工作

选首先安装这几个软件：GCC，PCRE（Perl Compatible Regular Expression），zlib，OpenSSL。

Nginx是C写的，需要用GCC编译；Nginx的Rewrite和HTTP模块会用到PCRE；Nginx中的Gzip用到zlib；

用命令“# gcc”，查看gcc是否安装；如果出现“gcc: no input files”信息，说明已经安装好了。

否则，就需要用命令“# yum install gcc”，进行安装了！一路可能需要多次输入y，进行确认。

安装好后，可以再用命令“#gcc”测试，或者用命令“# gcc -v”查看其版本号。

同样方法，用如下命令安装PCRE，zlib，OpenSSL（其中devel，是develop开发包的意思）：

# yum install -y pcre pcre-devel

# yum install -y zlib zlib-devel

# yum install -y openssl openssl-devel

2、下载并安装

创建目录（nginx-src）并进去；然后，从官方地址（http://nginx.org/）下载，解压，配置，编译，安装：

# mkdir nginx-src && cd nginx-src

# wget http://nginxorg/download/nginx-targz

# tar xzf nginx-targz

# cd nginx-3

# /configure

# make

# make install

# whereis nginx

nginx: /usr/local/nginx

默认的安装路径为：/usr/local/nginx；跳转到其目录下sbin路径下，便可以启动或停止它了。

# /nginx -h

nginx version: nginx/3

Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:

-?,-h : this help

-v : show version and exit

-V : show version and configure options then exit

-t : test configuration and exit

-q : suppress non-error messages during configuration testing

-s signal : send signal to a master process: stop, quit, reopen, reload

-p prefix : set prefix path (default: /usr/local/nginx/)

-c filename : set configuration file (default: conf/nginxconf)

-g directives : set global directives out of configuration file

启动：nginx

停止：nginx -s stop

3、添加到系统服务

使用命令“# vi /etc/init.d/nginx”，打开编辑器，输入如下内容：


#!/bin/sh 
# chkconfig: 2345 85 15 
# Startup script for the nginx Web Server 
# description: nginx is a World Wide Web server  
# It is used to serve HTML files and CGI 
# processname: nginx 
# pidfile: /usr/local/nginx/logs/nginxpid 
# config: /usr/local/nginx/conf/nginxconf 
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin 
DESC="nginx deamon" 
NAME=nginx 
DAEMON=/usr/local/nginx/sbin/$NAME 
SCRIPTNAME=/etc/initd/$NAME 
test -x $DAEMON || exit 0 
d_start(){ 
 $DAEMON || echo -n "already running" 
} 
d_stop(){ 
 $DAEMON -s quit || echo -n "not running" 
} 
d_reload(){ 
 $DAEMON -s reload || echo -n "can not reload" 
} 
case "$1" in 
start) 
 echo -n "Starting $DESC: $NAME" 
 d_start 
 echo "" 
;; 
stop) 
 echo -n "Stopping $DESC: $NAME" 
 d_stop 
 echo "" 
;; 
reload) 
 echo -n "Reloading $DESC conf" 
 d_reload 
 echo "reload " 
;; 
restart) 
 echo -n "Restarting $DESC: $NAME" 
 d_stop 
 sleep 2 
 d_start 
 echo "" 
;; 
*) 
 echo "Usage: $ScRIPTNAME {start|stop|reload|restart}" >&2 
 exit 3 
;; 
esac 
exit 0
