CentOS 6.3下搭建Web服务器

系统版本

查看系统版本

[root@localhost ~]# uname -a
Linux centos-6-3 2.6.32-279.22.1.el6.x86_64 #1 SMP Wed Feb 6 03:10:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

准备工作

1. 修改selinux配置文件(/etc/sysconfig/selinux) 关闭防火墙

sed -i 's|^SELINUX=enforcing|SELINUX=disabled|g' /etc/selinux/config

2. 修改防火墙开放80、3306端口号，配置文件(/etc/sysconfig/iptables)

echo '' >> /etc/sysconfig/iptables
echo '-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT' >> /etc/sysconfig/iptables
echo '-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT' >> /etc/sysconfig/iptables

一、安装MySQL

1. 安装、设置随机启动、启动服务

yum -y install mysql mysql-server  #yum安装

chkconfig --levels 235 mysqld on   #设置随机启动

service mysqld start               #启动
service mysqld restart             #重启
service mysqld status              #查看状态
service mysqld stop                #停止

2. 修改mysql密码

mysql_secure_installation

回显如下：

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] y
New password: 
Re-enter new password: 
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] y
 ... 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] n
 ... skipping.

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] n
 ... skipping.

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... 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!

3. 链接mysql, 表明安装成功

mysql -hlocalhost -uroot -p

二、安装apache

1. 安装、设置随机启动、启动服务

yum -y install httpd              #yum安装

chkconfig --levels 235 httpd on   #设置随机启动

service httpd start               #启动
service httpd restart             #重启
service httpd status              #查看状态
service httpd stop                #停止

2. 访问测试页，http://192.168.168.142

三、安装PHP5

1. 安装

yum -y install php

service httpd restart    #重启httpd

2. 添加测试代码

echo '<?php phpinfo();' > /var/www/html/info.php

3. 访问测试代码，http://192.168.168.142/info.php

4. 添加PHP5扩展模块

查询当前系统版本支持的模块

yum search php

service httpd restart    #重启httpd

访问测试页，查验是否已正确安装新模块：

四、安装phpMyAdmin

1. 首先前往官方网站下载：phpMyAdmin-4.4.13-all-languages.zip，然后上传解压到/usr/share/目录下

2. 编辑配置文件，vi /etc/httpd/conf.d/phpmyadmin.conf，内容如下：

#
#   Web application to manage llySQL
#
#<Directory "/usr/share/phpmyadmin"
#   Order Deny,Allow
#   Deny from all
#   Allow from 127.0.0.1
#</Directory>

Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phplyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin

3. 配置phpmyadmin:

cp /usr/share/phpmyadmin/config.sample.inc.php /usr/share/phpmyadmin/config.inc.php
vi /usr/share/phpmyadmin/config.inc.php
