LAMP（Linux-Apache-MySQL-PHP）网站架构是目前国际流行的Web框架，该框架包括：Linux操作系统，Apache 网络服务器，MySQL数据库，Perl、PHP或者Python编程语言，所有组成产品均是开源软件，是国际上成熟的架构框架，很多流行的商业应用都是 采取这个架构，和Java/J2EE架构相比，LAMP具有Web资源丰富、轻量、快速开发等特点，微软的.NET架构相比，LAMP具有通用、跨平台、 高性能、低价格的优势，因此LAMP无论是性能、质量还是价格都是企业搭建网站的首选平台。
安装前准备：
1、检查防火墙iptables状态
[root@server ~]# service iptables status
注意：用法：iptables {start|stop|restart|condrestart|status|panic|save}
表格：filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
2 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0
3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22
5 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
Chain FORWARD (policy ACCEPT)
num target prot opt source destination
1 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
查看本机关于 IPTABLES的配置前情况
[root@server ~]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT icmp -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
Chain FORWARD (policy ACCEPT)
target prot opt source destination
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
2、配置防火墙，开启80端口、3306端口
[root@server ~]# vim /etc/sysconfig/iptables
添加：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT #允许80(http)端口通过防火墙
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT #允许3306(mysql)端口通过防火墙
备注：
很多网友把这两条规则添加到防火墙配置的最后一行，导致防火墙启动失败，正确的应该是添加到默认的22端口这条规则的下面。
如下所示：
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT #允许80(http)端口通过防火墙
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT #允许3306(mysql)端口通过防火墙
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
:wq #保存退出
重启防火墙使配置生效
[root@server ~]# service iptables restart
iptables：清除防火墙规则： [确定]
iptables：将链设置为政策 ACCEPT：filter [确定]
iptables：正在卸载模块： [确定]
iptables：应用防火墙规则： [确定]
最后，检查防火墙iptables状态是否生效
[root@server ~]# service iptables status
表格：filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
2 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0
3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22
5 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:80
6 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:3306
7 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
Chain FORWARD (policy ACCEPT)
num target prot opt source destination
1 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
3、关闭SELINUX
[root@server ~]# vim /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
#SELINUX=enforcing #注释掉强制
SELINUX=disabled #关闭
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
#SELINUXTYPE=targeted #注释掉
:wq #保存退出
重启系统
[root@server ~]# reboot

4、安装Apache
检查是否安装httpd，使用YUM 自动安装：
[root@server ~]# rpm -qa |grep httpd
[root@server ~]# yum -y install httpd #根据提示，输入Y安装即可成功安装
启动Apache
[root@server ~]# service httpd start
正在启动 httpd：httpd: apr_sockaddr_info_get() failed for server
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[确定]
设为开机启动
[root@server ~]# chkconfig httpd on
重启Apache
[root@server ~]# service httpd restart
停止 httpd： [确定]
正在启动 httpd：httpd: apr_sockaddr_info_get() failed for server
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[确定]
查看启动Apache运行状态
[root@server ~]# service httpd status
httpd (pid 1290) 正在运行...
浏览器访问：http://192.168.1.94
5、安装MySQL
检查是否安装mysql，使用YUM 自动安装：
[root@server ~]# rpm –qa |grep mysql
[root@server ~]# yum -y install mysql mysql-server #是否要安装，输入Y即可自动安装,直到安装完成
启动MySQL
[root@server ~]# service mysqld start
[确定]
正在启动 mysqld： [确定]
设为开机启动
[root@server ~]# chkconfig mysqld on
[root@server ~]# cp /etc/my.cnf /etc/my.cnfbak
[root@server ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y #拷贝配置文件（注意：如果/etc目录下面默认有一个my.cnf，直接覆盖即可）
为root账户设置密码
[root@server ~]# 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): #按回车键
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 #输入y
New password: #输入新密码
Re-enter new password: #重输入新密码
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] y #输入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] y #输入y
... 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] y #输入y
- 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] y #输入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! #最后出现：Thanks for using MySQL!
MySql密码设置完成，重新启动 MySQL：
[root@server ~]# service mysqld restart
停止 mysqld： [确定]
正在启动 mysqld： [确定]
[root@server ~]# service mysqld stop
停止 mysqld： [确定]
[root@server ~]# service mysqld start

[root@server ~]#
6、安装PHP5
检查是否安装php，使用YUM 自动安装：
[root@server ~]# rpm –qa |grep php
[root@server ~]# yum -y install php #根据提示输入Y直到安装完成
安装PHP组件，使 PHP5 支持 MySQL
[root@server ~]# yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt
#这里选择以上安装包进行安装，根据提示输入Y回车
