在CentOS6.4中安装配置LAMP环境的详细步骤

　　本文详细介绍了CentOS6.4系统中安装LAMP服务并对其进行配置的过程，即安装Apache+PHP+Mysql，参照了网上大神的设置，其他Linux发行系统可以参考~

　　在本文中部分命令操作需要root权限，输入‘’命令后输入密码即可切换root身份。

设置文件允许80端口和3306端口。因为80端口是http协议所使用的端口，如果防火墙禁止80端口的话，网站配置好了也无法从外网访问。3306端口是MySql数据库的默认端口。使用VIM打开iptables文件并添加规则：

 

<span 1</span> <span 打开iptables文件进行修改
</span><span 2</span> vim /etc/sysconfig/<span iptables
</span><span 3</span> 
<span 4</span> <span 加入下列两行
</span><span 5</span> -A INPUT -p tcp -m state --state NEW -m tcp --dport <span 80</span> -<span j ACCEPT
</span><span 6</span> -A INPUT -p tcp -m state --state NEW -m tcp --dport <span 3306</span> -j ACCEPT

　　添加好后文件应该如下图，如果以前修改过该文件责可能和笔者的图中略有不同：

　　

2. 关闭SELINUX

中提供的(）系统。对于目前可用的 安全模块来说，SELinux 是功能最全面，基本上都是用负载均衡设备做流量分发，对外仅开放了仅有的几个端口。所以综合安全性和复杂性来说，SELinux的性价比并不高。修改文件关闭SELinux，设置后如图：

<span 1</span> vim /etc/selinux/<span config
</span><span 2</span> 
<span 3</span> <span 注释掉如下两行，在行首添加#注释。
</span><span 4</span> SELINUX=<span enforcing
</span><span 5</span> SELINUXTYPE=<span targeted
</span><span 6</span> 
<span 7</span> <span 在后面增加：
</span><span 8</span> SELINUX=disabled

’重启系统。

<span  1</span> <span 通过yum软件包管理器安装MySql，管理器会自动安装依赖项，遇到询问直接输入y确认，直到显示&ldquo;Complete！&rdquo;完成。
</span><span  2</span> <span yum</span> <span install</span> mysql mysql-<span server
</span><span  3</span> 
<span  4</span> <span 启动MySql
</span><span  5</span> /etc/init.d/<span mysqld start
</span><span  6</span> 
<span  7</span> <span 设置MySql服务为开机启动
</span><span  8</span> <span chkconfig mysqld on
</span><span  9</span> 
<span 10</span> <span 复制MySql默认配置文件，直接覆盖/etc/my.cnf
</span><span 11</span> <span cp</span> /usr/share/mysql/my-medium.cnf /etc/my.cnf

MySql设置：

<span <span 输入如下命令后需要连续输入两次密码确认，有询问输入Y同意即可，成功后显示</span></span><span Thanks for using MySQL!。</span>

<span mysql_secure_installation</span>

　　设置成功后需要重启MySql服务：

<span 1</span> /etc/init.d/<span mysqld stop
</span><span 2</span> /etc/init.d/mysqld start

2. Apache服务的安装和配置

　　

<span  1</span> <span 安装httpd
</span><span  2</span> <span yum</span> <span install</span><span  httpd
</span><span  3</span> 
<span  4</span> <span 启动Apache服务
</span><span  5</span> /etc/init.d/<span httpd start
</span><span  6</span> 
<span  7</span> <span 编辑apache设置
</span><span  8</span> vim /etc/httpd/conf/<span httpd.conf
</span><span  9</span> <span 查找 <span #ServerName www.example.com:80</span></span>
<span 10</span> <span 修改成 <span ServerName</span> <span www.XXXX.com:80</span></span> 
<span 11</span> <span 其中的&ldquo;www.XXXX.com&rdquo;自己的域名，没有可设置为localhost，如图
</span><span 12</span> 
<span 13</span> <span 设置Apache服务开机启动
</span><span 14</span> <span chkconfig httpd on
</span><span 15</span> 
<span 16</span> <span 重启Apache服务
</span><span 17</span> /etc/init.d/httpd restart

3.安装PHP

　　

<span 遇到询问直接输y确认
</span><span yum</span> <span install</span> php

　　安装PHP插件：

<span 插件包括MySql支持等，遇到询问一如既往的y确认~~
</span><span yum</span> <span install</span> php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt

　　安装完成后不要忘了重启Apache和MySql：

/etc/init.d/<span mysqld restart
</span>/etc/init.d/httpd restart

　　

　　到此软件的安装就结束了，接下来进行配置和测试。
