1、首先要安装nginx模块的依赖包

yum install gcc-c++  
yum install pcre pcre-devel  
yum install zlib zlib-devel  
yum install openssl openssl-devel

2、检查一下是否已经安装有nginx

find -name nginx

3、如果系统已经安装了nginx，则先卸载

yum remove nginx

4、进入/usr/local目录

cd /usr/local

5、从官网下载最新稳定版nginx

wget http://nginx.org/download/nginx-1.6.2.tar.gz

6、解压

tar -zxvf nginx-1.6.2.tar.gz

7、进入目录

cd  nginx-1.6.2

8、接下来安装，使用--prefix参数指定nginx安装的目录,配置configure、编译make、安装make install

./configure  $默认安装在/usr/local/nginx   
make  
make install

9、安装完成，查看安装目录

whereis nginx

10、进入安装目录

cd  /usr/local/nginx/sbin
./nginx -t

效果如下，说明配置文件nginx.conf没有问题：

11、启动nginx

[root@localhost sbin]# ./nginx
（重启指令：# ./nginx -s reload）

12、查看端口号

[root@localhost sbin]# netstat -ntlp

13、打开浏览器访问（默认端口80）

附：

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

-c制定配置文件的路径，不加-nginx会自动加载默认路径的配置文件。

如果nginx启动过程提示：

error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

解决方法：

ln -s /usr/local/lib/libpcre.so.1 /lib64

32位系统则：

ln -s /usr/local/lib/libpcre.so.1 /lib

注：
/usr/local/lib/libpcre.so.1 为prce安装后的文件地址
低版本prce对应的libpcre.so.1 为libpcre.so.0

nginx开机自启

这里使用的是编写shell脚本的方式来处理

vi /etc/init.d/nginx (输入下面的代码)

#!/bin/bash

# nginx Startup script for the Nginx HTTP Server

# it is v.0.0.2 version.

# chkconfig: - 85 15

# description: Nginx is a high-performance web and proxy server.

#              It has a lot of features, but it's not for everyone.

# processname: nginx

# pidfile: /var/run/nginx.pid

# config: /usr/local/nginx/conf/nginx.conf

nginxd=/usr/local/nginx/sbin/nginx

nginx_config=/usr/local/nginx/conf/nginx.conf

nginx_pid=/var/run/nginx.pid

RETVAL=0

prog="nginx"

# Source function library.

. /etc/rc.d/init.d/functions

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ ${NETWORKING} = "no" ] && exit 0

[ -x $nginxd ] || exit 0

# Start nginx daemons functions.

start() {

if [ -e $nginx_pid ];then

   echo "nginx already running...."

   exit 1

fi

   echo -n $"Starting $prog: "

   daemon $nginxd -c ${nginx_config}

   RETVAL=$?

   echo

   [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx

   return $RETVAL

}

# Stop nginx daemons functions.

stop() {

        echo -n $"Stopping $prog: "

        killproc $nginxd

        RETVAL=$?

        echo

        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid

}

# reload nginx service functions.

reload() {

    echo -n $"Reloading $prog: "

    #kill -HUP `cat ${nginx_pid}`

    killproc $nginxd -HUP

    RETVAL=$?

    echo

}

# See how we were called.

case "$1" in

start)

        start

        ;;

stop)

        stop

        ;;

reload)

        reload

        ;;

restart)

        stop

        start

        ;;

status)

        status $prog

        RETVAL=$?

        ;;

*)

        echo $"Usage: $prog {start|stop|restart|reload|status|help}"

        exit 1

esac

exit $RETVAL

设置文件的访问权限

chmod a+x /etc/init.d/nginx (a+x ==> all user can execute 所有用户可执行)

这样在控制台就很容易的操作nginx了：查看Nginx当前状态、启动Nginx、停止Nginx、重启Nginx…

同样的修改了nginx的配置文件nginx.conf，也可以使用上面的命令重新加载新的配置文件并运行，可以将此命令加入到rc.local文件中，这样开机的时候nginx就默认启动了

vi /etc/rc.local
