Linux（CentOS）环境下安装下载Nginx并配置

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
