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
