yum安装lamp

why

　　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

• [utterramblings]
  
• 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? [Y/n] <-- 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? [Y/n] <-- 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? [Y/n] <-- 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? [Y/n] <-- 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? [Y/n] <-- 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
