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。
在底部增加下面信息

name=Jason's Utter Ramblings Repo |
3 |
baseurl=http://www.jasonlitka.com/media/EL$releasever/$basearch/ |

gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka |
安装MySQL
执行yum程序安装MySQL
1 |
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：
1 |
chkconfig --levels 235 mysqld on |
2 |
/etc/init.d/mysqld start |
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 |
password for the root user. If you've just installed MySQL, and |
06 |
you haven't set the root password yet, the password will be blank, |
07 |
so you should just press enter here. |
09 |
Enter current password for root (enter for none): |
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 created for |
24 |
them. This is intended only for testing, and to make the installation |
25 |
go a bit smoother. You should remove them before moving into a |
26 |
production environment. |
28 |
Remove anonymous users? [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 only for testing, and should be removed |
39 |
before moving into a production environment. |
41 |
Remove test database and access to it? [Y/n] <-- ENTER |
42 |
- Dropping test database... |
44 |
- Removing privileges on test database... |
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 |
All done! If you've completed all of the above steps, your MySQL |
56 |
installation should now be secure. |
58 |
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：
设置系统启动时自启动Apache
1 |
chkconfig --levels 235 httpd on |
并启动Apache
1 |
/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：
然后重启Apache服务器:
1 |
/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：
选择一些你需要的模块进行安装：
1 |
yum install php-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/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。
1 |
vi /etc/httpd/conf.d/phpmyadmin.conf |
填入如下内容：
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。
