Centos下快速安装Nginx

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

一般习惯于在/usr/local/src目录下载安装包,进入目录然后,从官方地址(http://nginx.org/en/download.html)下载,解压,配置,编译,安装:

# cd /usr/local/src
# wget http://nginx.org/download/nginx-1.8.1.tar.gz
# tar xzf nginx-1.8.1.tar.gz
# cd nginx-1.8.1 
# ./configure  
# make  
# make install

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/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
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/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:DESC:NAME"  
  d_start  
  echo "."  
;;  
stop)  
  echo -n "Stopping DESC:DESC:NAME"  
  d_stop  
  echo "."  
;;  
reload)  
  echo -n "Reloading $DESC conf..."  
  d_reload  
  echo "reload ."  
;;  
restart)  
  echo -n "Restarting DESC:DESC:NAME"  
  d_stop  
  sleep 2  
  d_start  
  echo "."  
;;  
*)  
  echo "Usage: $ScRIPTNAME {start|stop|reload|restart}" >&2  
  exit 3  
;;  
esac
 exit 0   //保存退出后,再使用下面的命令,使其可执行;然后,添加配置并查看。

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  
nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off

ok,访问ip。
