yum安装lamp
LAMP是Linux,Apache,MySQL,PHP的缩写。这个教程主要是讲在centos安装有php和mysql支持的apache web服务器。添加外部源，保证MySQL和PHP最新
因为系统基本的源的MySQL和PHP程序比较旧，所以我们添加比较新的外部源。
[*]# rpm --import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
[*]# vi /etc/yum.repos.d/CentOS-Base.repo
在底部增加下面信息
[*]
[*]name=Jason's Utter Ramblings Repo
[*]baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/
[*]enabled=1
[*]gpgcheck=1
[*]gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka
安装MySQL
执行yum程序安装MySQL
[*]yum install mysql mysql-server
添加MySQL进启动项（这样系统启动时会自动启动MySQL)，并立即启动MySQL服务器：
[*]chkconfig --levels 235 mysqld on
[*]/etc/init.d/mysqld start
设置MySQL root帐号密码：
[*]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? <-- ENTER
[*]New password: <-- 你的MySQL root密码
[*]Re-enter new password: <-- 你的MySQL root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? <-- ENTER
[*] ... 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? <-- ENTER
[*] ... 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? <-- ENTER
[*] - 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? <-- ENTER
[*] ... 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!
安装Apache
Apache在CentOS软件包可用，因此我们可以使用yum安装：
[*]yum install httpd
设置系统启动时自启动Apache
[*]chkconfig --levels 235 httpd on
并启动Apache
[*]/etc/init.d/httpd start
现在你直接在你的浏览器键入http://192.168.0.100,你就应该会看到Apache的测试页面。
安装PHP
我们可以按照下面的命令安装PHP和Apache PHP模块：
[*]yum install php
然后重启Apache服务器:
[*]/etc/init.d/httpd restart
安装相关模块使用PHP支持MySQL
为了让PHP支持MySQL，我们可以安装php-mysql软件包。你也可以安装其它的php模块。可以使用以下命令搜索可用的php模块：
[*]yum search php
选择一些你需要的模块进行安装：
[*]yum install php-mysql php-common php-mbstring php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
添加apache支持php:
编辑/etc/httpd/conf/httpd.conf，添加：
[*]Addtype application/x-httpd-php .php
现在重启Apache:
[*]/etc/init.d/httpd restart
安装phpMyAdmin
phpMyAdmin是一个可视化管理你的MySQL数据库的软件。
安装很简单,下载解压到根目录即可.
下载地址:http://www.phpmyadmin.net/home_page/downloads.php
接着我们配置phpMyAdmin，为了使用phpMyAdmin不仅仅只允许localhost连接，我们修改一下apache的配置。
[*]vi /etc/httpd/conf.d/phpmyadmin.conf
填入如下内容：
[*]#
[*]#Web application to manage MySQL
[*]#
[*]
[*]#<Directory "/usr/share/phpmyadmin">
[*]#Order Deny,Allow
[*]#Deny from all
[*]#Allow from 127.0.0.1
[*]#</Directory>
[*]Alias /phpmyadmin /usr/share/phpmyadmin
重启apache:
/etc/init.d/httpd restart
然后你就可以通过http://ip地址/phpmyadmin/进入phpMyAdmin了
