| VEVB友情提示：CentOS 5.x yum安装LAMP(Apache+MySQL+PHP)。 |
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。在这个教程我使用主机名server1.example.com对应IP地址192.168.0.100。这些设置可能不同于你，你必须替换成你正确的。
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。
| 1 | # rpm --import http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka |
| 2 | # vi /etc/yum.repos.d/CentOS-Base.repo |
在底部增加下面信息
| 2 | name=Jason's Utter Ramblings Repo |
| 3 | baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/ |
| 6 | gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka |
安装MySQL
执行yum程序安装MySQL
| 1 | yuminstallmysql 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：
| 1 | chkconfig --levels 235 mysqld on |
| 2 | /etc/init.d/mysqldstart |
设置MySQL root帐号密码：
| 1 | mysql_secure_installation |
| 01 | NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL |
| 02 | SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! |
| 04 | In order to log into MySQL to secure it, we'll need the current |
| 05 | passwordforthe root user. If you've just installed MySQL, and |
| 06 | you haven'tsetthe root password yet, the password will be blank, |
| 07 | so you should just press enter here. |
| 09 | Enter current passwordforroot (enterfornone): |
| 10 | OK, successfully used password, moving on... |
| 12 | Setting the root password ensures that nobody can log into the MySQL |
| 13 | root user without the proper authorisation. |
| 15 | Set root password? [Y/n] <-- ENTER |
| 16 | New password: <-- 你的MySQL root密码 |
| 17 | Re-enter new password: <-- 你的MySQL root密码 |
| 18 | Password updated successfully! |
| 19 | Reloading privilege tables.. |
| 22 | By default, a MySQL installation has an anonymous user, allowing anyone |
| 23 | to log into MySQL without having to have a user account createdfor |
| 24 | them. This is intended onlyfortesting, and tomakethe installation |
| 25 | go a bit smoother. You should remove them before moving into a |
| 26 | production environment. |
| 28 | Remove anonymoususers? [Y/n] <-- ENTER |
| 31 | Normally, root should only be allowed to connect from'localhost'. This |
| 32 | ensures that someone cannot guess at the root password from the network. |
| 34 | Disallow root login remotely? [Y/n] <-- ENTER |
| 37 | By default, MySQL comes with a database named'test'that anyone can |
| 38 | access. This is also intended onlyfortesting, and should be removed |
| 39 | before moving into a production environment. |
| 41 | Removetestdatabase and access to it? [Y/n] <-- ENTER |
| 42 | - Droppingtestdatabase... |
| 44 | - Removing privileges ontestdatabase... |
| 47 | Reloading the privilege tables will ensure that all changes made so far |
| 48 | will take effect immediately. |
| 50 | Reload privilege tables now? [Y/n] <-- ENTER |
| 55 | Alldone! If you've completed all of the above steps, your MySQL |
| 56 | installation should now be secure. |
安装Apache
Apache在CentOS软件包可用，因此我们可以使用yum安装：
设置系统启动时自启动Apache
| 1 | chkconfig --levels 235 httpd on |
并启动Apache
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：
然后重启Apache服务器:
| 1 | /etc/init.d/httpdrestart |
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：
选择一些你需要的模块进行安装：
| 1 | yuminstallphp-mysql php-common php-mbstring php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc |
现在重启Apache:
| 1 | /etc/init.d/httpdrestart |
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。
| 1 | vi/etc/httpd/conf.d/phpmyadmin.conf |
填入如下内容：
| 02 | # Web application to manage MySQL |
| 05 | #<directory share="" phpmyadmin?="" usr="" ?=""> |
| 08 | # Allow from 127.0.0.1 |
| 11 | Alias/phpmyadmin/usr/share/phpmyadmin |
| 12 | Alias/phpMyAdmin/usr/share/phpmyadmin |
| 13 | Alias/mysqladmin/usr/share/phpmyadmin |
重启apache:
/etc/init.d/httpd restart
然后你就可以通过http://192.168.0.100/phpmyadmin/进入phpMyAdmin了。
