LAMP就是Linux+Apache+MySql+PHP搭建的动态网站环境，是目前互联网上非常流行的一个网页服务组合。
网上有很多教程搭建LAMP环境，基本上都是编译安装的，其实对新手来说只需要了解LAMP环境的一些特性，RMP安装相对来说容易上手点，只需要安装几个光盘上的安装包就可以顺利完成LAMP的搭建。

Installing all prepared tables
Fill help tables
To start mysqld at boot time you have to copy support-files/mysql.server
to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h linux-a.test.com password 'new-password'
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory:
cd sql-bench ; perl run-all-tests
Please report any problems with the /usr/bin/mysqlbug script!

测试配置：
安装好之后Apache的配置文件在/etc/httpd/conf/httpd.conf 基本不需要修改，详细设置参数可以参考[Apache2配置文件httpd.conf中文版 (转)]
编译安装php之后都需要手动修改Apache的配置文件，这里不需要修改，安装PHP时会生成一个/etc/httpd/conf.d/php.conf 文件，Apache配置文件可以直接饮用这个配置
#
# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
#
LoadModule php5_module modules/libphp5.so
#
# Cause the PHP interpreter to handle files with a .php extension.
#
AddHandler php5-script .php
AddType text/html .php
#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php
#
# Uncomment the following line to allow PHP to pretty-print .phps
# files as PHP source code:
#
#AddType application/x-httpd-php-source .phps
如果是编译安装的话只需要将上面红色的文字加到/etc/httpd/conf.d/php.conf 配置文档中就可以了。
php的配置文件在/etc/php.ini ，也不需要修改，除非你需要配置一些高级功能。
MySql的配置文件在/etc/my.cnf。
启动Apache和MySql服务
在网页目录下建立一个php测试文件，如果能出现正确的php环境信息说明安装已经成功。
[root@linux-a ~]# vim /var/www/html/index.php
<?
phpinfo();
?>
上传一个WordPress程序到/var/www/html/目录下，将其目录的权限修改为777，进行WordPress安装测试，这样一个LAMP环境就搭建起来了。
