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://nginx.org/download/nginx-1.7.3.tar.gz
- # tar xzf nginx-1.7.3.tar.gz
- # cd nginx-1.7.3
- # ./configure
- # make
- # make install
- # whereis nginx
- nginx: /usr/local/nginx
- # ./nginx -h
- nginx version: nginx/1.7.3
- 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/nginx.conf)
- -g directives : set global directives out of configuration file
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/nginx.pid
- # config: /usr/local/nginx/conf/nginx.conf
- PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
- DESC="nginx deamon"
- NAME=nginx
- DAEMON=/usr/local/nginx/sbin/$NAME
- SCRIPTNAME=/etc/init.d/$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
可用chkconfig修改其值，也可用ntsysv工具改变是否自启动。
- # chmod +x /etc/init.d/nginx
- # chkconfig --add nginx
- # chkconfig nginx on/off
- # chkconfig --list nginx
