CentOS 系统 LAMP(Apache+MySQL+PHP)的安装
重启MySQL: /etc/init.d/mysqld restart ; 重启Apache: /etc/init.d/httpd start
Apache的配置文件路径：/etc/httpd/conf/httpd.conf ; PHP配置文件路径: /etc/php.ini
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
一般情况下，安装的都是最新的正式版，除非你有特殊需求，要安装指定的版本，本文暂不讨论。从最基础的开始，一点点完成一个可用的 Linux 主机。这里就开始介绍如何在 CentOS 6.0 上安装 LAMP 组件。经过如下语句安装，目前安装到的版本为：PHP：5.3.2
Apache：2.2.15
MySQL：5.1.52一、安装 MySQL
首先来进行 MySQL 的安装。打开超级终端，输入：
安装完毕，让 MySQL 能够随系统自动启动：
设置 MySQL 数据 root 账户的密码：（本人MySQL的密码为：123456）
当出现如下提示时候直接按回车：
Enter current password for root
出现如下再次回车：
Set root password? [Y/n]
出现如下提示输入你需要设置的密码，回车后在输入一次确认：
New password:
接下来还会有四个确认，分别是：
- Remove anonymous users? [Y/n]
- Disallow root login remotely? [Y/n]
- Remove test database and access to it? [Y/n]
- Reload privilege tables now? [Y/n]
直接回车即可。
二、安装 Apache 组件
由于 CentOS 已经封装了 Apache，直接运行安装：
同样配置系统让 Apache 随系统启动：
配置完毕，启动 Apache：
此时已经可以访问你的服务器，不出意外的话，能够看到 “Apache 2 Test Page powered by CentOS” 的测试页面。注意，如果其他机器访问这台服务无法显示这个页面，而直接在这台服务器上可以访问的话，一般情况下是 CentOS 自带的防火墙禁止了。你只需要进入防火墙，将 “WWW” 对应的 “80” 端口打开即可。
注意：在 CentOS 中 Apache 的默认根目录是 /var/www/html，配置文件 /etc/httpd/conf/httpd.conf。其他配置存储在 /etc/httpd/conf.d/ 目录。
三、安装 PHP
输入如下指令安装 PHP:
root@localhost ~]# yum install -y php
需要重新启动 Apache 服务：
[root@localhost ~]# /etc/init.d/httpd restart
四、测试 PHP 相关信息
这步实际上可以省略，但是为了测试是否安装成功，你可以新建一个 PHP 页面进行测试，使用 vim 编辑器新建：
[root@localhost ~]# vi /var/www/html/info.php
按 “i” 键进行编辑，输入：
<?php phpinfo(); ?>
编辑完毕，按 “ESC” 键退出编辑模式，接着输入：
:wq
然后回车，即保存并退出。
此时你可以访问你的站点地址，例如 “http://192.168.1.2/info.php”，查看是否能看到相关的 PHP 信息。
看到这样的图，就说明 PHP 安装成功了。
五、将 PHP 模块和 MySQL 模块关联起来
还需要将 PHP 和 MySQL 关联起来，才能正常工作。搜索模块：
[root@localhost ~]# yum search php
安装相关模块：
[root@localhost ~]# yum install -y php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
需要重启 Apache 模块才能生效：
[root@localhost ~]# /etc/init.d/httpd restart
再次刷新刚才建立的 “info.php” 页面，往下拉找到相关 MySQL 模块，看是否检测到相关信息。
如果看到如上图相关信息，则说明 MySQL 工作正常了。
六、总结
到这里就结束了，本文阐述了在 CentOS 6.0 系统下 LAMP 组件（Apache+MySQL+PHP） 的详细安装步骤，可以让更多新手熟悉服务器配置环境。
但是到这里，还只是将环境配置完毕，很多东西还有欠缺，而且还是一些重要的问题，例如目录的权限配置问题，或者是管理上的问题，像建立 FTP 等。这些内容随后会慢慢谈到。
