Apache配置虚拟主机的三种方法（基于IP、端口、域名）
之前写过一次Mac为Apache2配置虚拟主机流程，后来由于个人失误，把记录丢了。浏览之余，发现一篇网友写的很棒的博客，特此收藏，便于后期学习。
1 Apache虚拟主机的实现方式有3种
- 基于IP的虚拟主机
- 基于端口的虚拟主机
- 基于域名的虚拟主机
2.1 启用虚拟主机的准备工作
2.1.1 安装httpd
[root@mail httpd]# yum install httpd -y
2.1.2 禁用默认的主机模式
[root@mail httpd]# vim /etc/httpd/conf/httpd.conf
#注释下面这行内容
#DocumentRoot "/var/www/html"
2.2 基于IP的虚拟主机配置
2.2.1 为主机添加多个IP
[root@localhost conf.d]# ip addr show dev eth0 #查看原有IP
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:77:77:7d brd ff:ff:ff:ff:ff:ff
inet 192.168.137.200/24 brd 192.168.137.255 scope global eth0
inet6 fe80::20c:29ff:fe77:777d/64 scope link
valid_lft forever preferred_lft forever
[root@localhost conf.d]# ip addr add 192.168.137.201/24 dev eth0 #添加一个IP
[root@localhost conf.d]# ip addr show dev eth0 #查看添加后的IP信息， 此时有2个IP地址了。 200,201
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:77:77:7d brd ff:ff:ff:ff:ff:ff
inet 192.168.137.200/24 brd 192.168.137.255 scope global eth0
inet 192.168.137.201/24 scope global secondary eth0
inet6 fe80::20c:29ff:fe77:777d/64 scope link
valid_lft forever preferred_lft forever
2.2.2 添加虚拟主机配置文件
[root@mail conf.d]# cd /etc/httpd/conf.d/ #进入配置目录
[root@mail conf.d]# vim virtualhost.conf #创建一个配置文件， 编辑内容如下
[root@mail conf.d]# cat virtualhost.conf #查看并检查配置文件
<VirtualHost 192.168.137.200:80>
DocumentRoot "/var/www/test200"
ServerName www.test200.com
</VirtualHost>
<VirtualHost 192.168.137.201:80>
DocumentRoot "/var/www/test201"
ServerName www.test201.com
</VirtualHost>
[root@mail conf.d]# cd /var/www #切换目录
[root@mail www]# mkdir test200 test201 #创建目录
[root@mail www]# echo test200 >>./test200/index.html #创建IP为200的主页
[root@mail www]# echo test201 >>./test201/index.html #创建IP为200的主页
2.2.3 测试
[root@localhost www]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName
[ OK ]
# 我们这里使用elinks进行测试， 当然用浏览器测试是一样的
[root@localhost conf]# elinks -source 192.168.137.200
test200
[root@localhost conf]# elinks -source 192.168.137.201
test201
2.3 基于端口的虚拟主机配置
2.3.1 在主配置文件添加监听端口
[root@localhost conf]# vim /etc/httpd/conf/httpd.conf
在原有行Listen 80行的基础上， 在添加一行
Listen 8080
2.3.2 添加8080的端口虚拟配置
[root@localhost conf.d]# cat virtualhost.conf
<VirtualHost 192.168.137.200:80>
DocumentRoot "/var/www/test200"
ServerName www.test200.com
</VirtualHost>
<VirtualHost 192.168.137.201:80>
DocumentRoot "/var/www/test201"
ServerName www.test201.com
</VirtualHost>
#下面的内容是在上面的配置的基础上添加的。
<VirtualHost 192.168.137.201:8080>
DocumentRoot "/var/www/test201-8080"
ServerName www.test201-8080.com
</VirtualHost>
[root@localhost conf.d]# cd /var/www/ #切换目录
[root@localhost www]# mkdir test201-8080 #创建目录
[root@localhost www]# echo "test201-8080" >>./test201-8080/index.html #创建主页
2.3.2 测试
[root@localhost www]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName
[ OK ]
[root@localhost conf]# elinks -source 192.168.137.201:80
test201
[root@localhost conf]# elinks -source 192.168.137.201
test201
[root@localhost conf]# elinks -source 192.168.137.201:8080
test201-8080
2.4 基于域名的虚拟主机配置
2.4.1 添加域名的虚拟主机配置
[root@localhost conf.d]# vim virtualhost.conf #编辑虚拟主机配置文件
[root@localhost conf.d]# cat virtualhost.conf #内容如下， 红色部分是在上面的基础上添加的
NameVirtualHost 192.168.137.200:80
<VirtualHost 192.168.137.200:80>
DocumentRoot "/var/www/test200"
ServerName www.test200.com
</VirtualHost>
<VirtualHost 192.168.137.200:80>
DocumentRoot "/var/www/test200net"
ServerName www.test200.net
</VirtualHost>
<VirtualHost 192.168.137.201:80>
DocumentRoot "/var/www/test201"
ServerName www.test201.com
</VirtualHost>
<VirtualHost 192.168.137.201:8080>
DocumentRoot "/var/www/test2018080"
ServerName www.test2018080.com
</VirtualHost>
[root@localhost conf.d]# !ser
service httpd restart
Stopping httpd: [ OK ]
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName
[ OK ]
[root@localhost conf.d]# cd /var/www #切换目录
[root@localhost www]# mkdir test200net #创建目录
[root@localhost www]# echo "test200net" >>./test200net/index.html #创建主页
2.4.2 测试
2.4.2.1 添加域名解析
这里我们没有提供dns去解析，简单的使用hosts文件区解析就可以了。
[root@localhost www]# vim /etc/hosts 编辑hosts文件， 添加两行
[root@localhost www]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.137.200 www.test200.com
192.168.137.200 www.test200.net
接下来就可以测试了
[root@localhost www]# elinks -source http://www.test200.com #测试.com域
test200
[root@localhost www]# elinks -source http://www.test200.net #测试.net域
test200net
