CentOS 6.0 上安装LAMP服务器

　　CentOS 6.0才发布不久，如今咱们来共同窗习一下如何在CentOS 6.0上安装Apache2 + PHP5 + MySQL的web服务器。
1.重要提示：
在本教程中使用的主机名为server1.example.com，IP 地址为192.168.0.100 。这些设置会与具体安装的设置有所不一样，因此你必须在你的安装过程当中进行替代。
2.安装MySQL 5.0
打开终端，输入：
yum install mysql mysql-server
而后为MySQL建立系统启动连接（这样在系统启动时，MySQL会自动启动），在终端输入命令：
chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start
为MySQL root账户设置密码：
mysql_secure_installation
终端显示，按照提示操做：
[root@server1 ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we’ll need the current
password for the root user.  If you’ve just installed MySQL, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root （enter for none）:
OK, successfully used password, moving on…
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] <– 回车
New password: <– 设置一个用户密码
Re-enter new password: <– 再输入一次你设置的密码
Password updated successfully!
Reloading privilege tables
…Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] <– 回车
…Success!
Normally, root should only be allowed to connect from ’localhost’。  This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] <–回车
…Success!
By default, MySQL comes with a database named ’test’ that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] <– 回车
- Dropping test database…
…Success!
- Removing privileges on test database…
…Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] <– 回车
…Success!
Cleaning up…
All done!  If you’ve completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
[root@server1 ~]#
3.安装的Apache2
yum install httpd
配置系统启动时自动启动apache
chkconfig --levels 235 httpd on
重启apache:
/etc/init.d/httpd start
在您的浏览器直接 http://192.168.0.100，你应该看到apache2的页面：
在CentOS中Apache的默认文档的根目录是/var/www/html，配置文件/etc/httpd/conf/httpd.conf。其余配置存储在/etc/httpd/conf.d/目录里。
4.Installing PHP5
咱们能够安装PHP5和Apache PHP5模块，命令以下：
yum install php
安装完成后必须从新启动Apache
/etc/init.d/httpd restart
5.测试PHP5 /获取PHP5安装的详细信息
默认的Web站点的文档根目录/var/www/html 。如今，咱们将在该目录中建立PHP探针文件（（info.php），在浏览器中调用它 。该文件将显示不少有用的细节，看看咱们安装的php模块安装时候完成。
vi /var/www/html/info.php
如今，在浏览器打开（如文件 http://192.168.0.100/info.php）：
正如您所看到的，PHP5工做正常，若是继续向下滚动，你会看到全部在PHP5中已经启用的模块 。没有MySQL，这意味着咱们php5中尚未MySQL支持模块。
6.在PHP5中添加MySQL支持
yum search php
挑选那些你须要的模块，安装：
yum install php-mysql php-gd php-imap php-ldap php-mbstring php-odbc php-pear php-xml php-xmlrpc
如今从新启动Apache2
/etc/init.d/httpd restart
7.安装phpMyAdmin管理数据库
phpMyAdmin是一个Web界面，经过它能够管理你的MySQL数据库。
首先，咱们使咱们的CentOS 系统的RPMForge软件库phpMyAdmin是否是官方的CentOS 6.0库：
导入rpmforge的GPG密钥：
rpm --import  http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
x86_64 系统安装命令：
yum install  http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
i386 系统安装命令：
yum install  http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
如今能够安装phpMyAdmin以下：
yum install phpmyadmin
如今，咱们配置phpMyAdmin。改变Apache的配置，使phpMyAdmin链接，而不单单是从localhost（注释掉容许） ：
vi /etc/httpd/conf.d/phpmyadmin.conf
#
# Web application to manage MySQL
#
#
# Order Deny,Allow
# Deny from all
# Allow from 127.0.0.1
#
Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin
下一步，咱们改变在phpMyAdmin的身份验证cookie ，HTTP：
vi /usr/share/phpmyadmin/config.inc.php
[…]
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = ‘http’；
[…]
从新启动Apache：
/etc/init.d/httpd restart
以后，您能够根据访问phpMyAdmin  http://192.168.0.100/phpmyadmin/管理数据库：
8.相关连接
