基于主机名的虚拟主机

[root@server html]# cp /usr/share/doc/httpd-2.4.6/httpd-vhosts.conf /etc/httpd/conf.d/01-www.baidu.com.conf
[root@server html]# cp /usr/share/doc/httpd-2.4.6/httpd-vhosts.conf /etc/httpd/conf.d/00-www.google.com.conf

内容

<VirtualHost *:@@Port@@>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "@@ServerRoot@@/docs/dummy-host.example.com"
    ServerName dummy-host.example.com
    ServerAlias www.dummy-host.example.com
    ErrorLog "/var/log/httpd/dummy-host.example.com-error_log"
    CustomLog "/var/log/httpd/dummy-host.example.com-access_log" common
</VirtualHost>

<VirtualHost *:@@Port@@>
    ServerAdmin webmaster@dummy-host2.example.com
    DocumentRoot "@@ServerRoot@@/docs/dummy-host2.example.com"
    ServerName dummy-host2.example.com
    ErrorLog "/var/log/httpd/dummy-host2.example.com-error_log"
    CustomLog "/var/log/httpd/dummy-host2.example.com-access_log" common
</VirtualHost>

2.创建主机目录

[root@server html]# mkdir -p /var/www/baidu
[root@server html]# mkdir -p /var/www/google
[root@server html]# echo baidu >> /var/www//baidu/index.html
[root@server html]# echo google >> /var/www/google/index.html

3.修改 Google 的配置文件

vim /etc/httpd/conf.d/00-www.google.com.conf

修改内容如下

<VirtualHost *:80>
    #ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "/var/www/google/"
    ServerName www.google.com
    ServerAlias www.dummy-host.example.com
    ErrorLog "/var/log/httpd/google.com-error_log"
    CustomLog "/var/log/httpd/google.com-access_log" common
 <Directory "/var/www/google">
    Require all granted
</Directory>
</VirtualHost>

4.修改 baidu 的配置文件

vim /etc/httpd/conf.d/00-www.baidu.com.conf

修改如下

<VirtualHost *:80>
    #ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "/var/www/baidu/"
    ServerName www.baidu.com
    #ServerAlias www.dummy-host.example.com
    ErrorLog "/var/log/httpd/baidu.com-error_log"
    CustomLog "/var/log/httpd/baidu.com-access_log" common
    <Directory "/var/www/baidu">
        Require all granted
    </Directory>
</VirtualHost>

5.重启 httpd

[root@server html]# systemctl restart httpd

重启 httpd

6.客户端访问

[root@desktop httpd]# vim /etc/hosts
[root@desktop httpd]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.10.100.128 www.baidu.com
172.10.100.128 www.google.comc

7.访问

[root@desktop ~]# curl -X GET http://www.baidu.com
baidu
[root@desktop ~]# curl -X GET http://www.google.com
google

基于端口的虚拟主机

其实基于端口就是在 /etc/httpd/conf/httpd.conf 增加一个监听端口

[root@server html]# cat  /etc/httpd/conf/httpd.conf | grep ^Listen
Listen 80
Listen 8080

然后比如我要把 Google 的访问端口改为8080,就是将原来的端口80 修改为8080

[root@server html]# cat /etc/httpd/conf.d/00-www.google.com.conf | grep 8080
<VirtualHost *:8080>

客户端访问

1.先测下端口通不通

[root@desktop ~]# telnet 172.10.100.128 8080
Trying 172.10.100.128...
Connected to 172.10.100.128.
Escape character is '^]'.
^C
Connection closed by foreign host.

2.然后访问

[root@desktop ~]#
[root@desktop ~]# curl -X GET http://www.google.com:8080 -v
* About to connect() to www.google.com port 8080 (#0)
*   Trying 172.10.100.128...
* Connected to www.google.com (172.10.100.128) port 8080 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.29.0
> Host: www.google.com:8080
> Accept: */*
