3种方法实现http虚拟主机

http访问

站点标识： socket

IP相同，但端口不同
IP不同，但端口均为默认端口
FQDN不同：请求报文中首部 Host: www.magedu.com

---

有三种实现方案：

基于ip：为每个虚拟主机准备至少一个ip地址
基于port：为每个虚拟主机使用至少一个独立的port
基于FQDN：为每个虚拟主机使用至少一个FQDN

1基于PORT的多虚拟主机

• 建立相应目录及index文件

#vim /etc/httpd/conf.d/vhosts.conf 
listen 8001
listen 8002
listen 8003

<virtualhost *:8001>
documentroot /data/site1
<directory /data/site1>
require all granted
</directory>
</virtualhost>

<virtualhost *:8002>
<directory /data/site2>                                                                                               
require all granted
</directory>
documentroot /data/site2
</virtualhost>

<virtualhost *:8003>
<directory /data/site3>                                                                                               
require all granted
</directory>
documentroot /data/site3
</virtualhost>

• 测试

  root:~ # curl 192.168.64.150:8001
  111
  root:~ # curl 192.168.64.150:8002
  222

  实验：基于ip的多虚拟主机

• 添加相应ip

ip a a 192.168.36.7 dev ens33
ip a a 192.168.36.8 dev ens33
ip a a 192.168.36.9 dev ens33

vim /etc/httpd/conf.d/vhosts.conf 
<virtualhost 192.168.36.7:80>
documentroot /data/site1
<directory /data/site1>
require all granted
</directory>
</virtualhost>

<virtualhost 192.168.36.8:80>
<directory /data/site2>
require all granted
</directory>
documentroot /data/site2
</virtualhost>

<virtualhost 192.168.36.9:80>                                                                                         
<directory /data/site3>
require all granted
</directory>
documentroot /data/site3
</virtualhost>

• 测试

  root:~ # curl 192.168.36.6
  111
  root:~ # curl 192.168.36.7
  222

实验：基于主机头的多虚拟主机

vim /etc/httpd/conf.d/vhosts.conf 
<virtualhost *:80>
documentroot /data/site1
servername www.a.com
<directory /data/site1>
require all granted
</directory>
CustomLog "logs/a_access_log" combined
</virtualhost>

<virtualhost *:80>
<directory /data/site2>                                                                                               
require all granted
</directory>
documentroot /data/site2
servername www.b.com
CustomLog "logs/b_access_log" combined
</virtualhost>

<virtualhost *:80>
servername www.c.com
<directory /data/site3>                                                                                               
require all granted
</directory>
documentroot /data/site3
CustomLog "logs/c_access_log" combined
</virtualhost>

• 在测试机上

在windows编辑  C:\Windows\System32\drivers\etc\hosts #吧只读去掉
192.168.36.7 www.a.com www.b.com www.c.com
