yum搭建lnmp环境（CentOS6.3)

在CentOS6.3下实践通过。

1.关闭防火墙

[root@CentOS
~]# chkconfig iptables off

2.关闭selinux

vi /etc/sysconfig/selinux 

//将SELINUX=enforcing修改为disabled然后重启生效

3、配置CentOS 6.0 第三方yum源（CentOS默认的标准源里没有nginx软件包）

[root@CentOS ~]# yum install wget

//下载wget工具

[root@CentOS ~]# wget http://www.atomicorp.com/installers/atomic
//下载atomic yum源

[root@CentOS ~]# sh ./atomic

//安装提示输入时输yes

[root@CentOS ~]# yum check-update

//更新yum软件包

4.安装开发包和库文件

[root@CentOS ~]# yum -y install ntp make openssl openssl-devel pcre
pcre-devel libpng 

libpng-devel libjpeg-6b libjpeg-devel-6b freetype freetype-devel gd
gd-devel zlib zlib-devel 

gcc gcc-c++ libXpm libXpm-devel ncurses ncurses-devel libmcrypt
libmcrypt-devel libxml2 

libxml2-devel imake autoconf automake screen sysstat
compat-libstdc++-33 curl curl-devel

5.卸载已安装的apache、mysql、php

[root@CentOS ~]# yum remove httpd

[root@CentOS ~]# yum remove mysql

[root@CentOS ~]# yum remove php

6.安装nginx

[root@CentOS ~]# yum install nginx

[root@CentOS ~]# service nginx start

[root@CentOS ~]# chkconfig --levels 235 nginx on

//设2、3、5级别开机启动

7.安装mysql

[root@CentOS ~]# yum install mysql mysql-server
mysql-devel

[root@CentOS ~]# service mysqld start

[root@CentOS ~]# chkconfig --levels 235 mysqld on

[root@CentOS ~]# mysqladmin -u root password
"123456"

//为root用户设置密码

[root@CentOS ~]# service mysqld restart

//重启mysql

8.安装php

[root@CentOS ~]# yum install php lighttpd-fastcgi php-cli php-mysql
php-gd php-imap php-ldap 

php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt
php-mssql php-snmp php-soap 

php-tidy php-common php-devel php-fpm

//安装php和所需组件使PHP支持MySQL、FastCGI模式

[root@CentOS ~]# service php-fpm start

[root@CentOS ~]# chkconfig --levels 235 php-fpm on

9.配置nginx支持php

[root@CentOS ~]# mv /etc/nginx/nginx.conf
/etc/nginx/nginx.confbak

//将配置文件改为备份文件

[root@CentOS ~]# cp /etc/nginx/nginx.conf.default
/etc/nginx/nginx.conf

//由于原配置文件要自己去写因此可以使用默认的配置文件作为配置文件

//修改nginx配置文件，添加fastcgi支持

[root@CentOS ~]# vi /etc/nginx/nginx.conf

index index.php index.html index.htm;

//加入index.php

location ~ \.php$ {

     
      root
     
   
/usr/share/nginx/html;

     
     
fastcgi_pass   127.0.0.1:9000;

     
     
fastcgi_index  index.php;

     
     
fastcgi_param  SCRIPT_FILENAME
 /usr/share/nginx/html$fastcgi_script_name;

     
      include
     
 fastcgi_params;

     
  }

//将以上代码注释去掉，并修改成nginx默认路径

10.配置php

//编辑文件php.ini，在文件末尾添加cgi.fix_pathinfo = 1

[root@CentOS ~]# vi /etc/php.ini

11.重启nginx php-fpm

[root@CentOS ~]# service nginx restart

[root@CentOS ~]# service php-fpm restart

12.建立info.php文件

[root@CentOS ~]# vi /usr/share/nginx/html/info.php
