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

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.
|
|

|
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。
