14、 三种虚拟主机

一、基于IP的虚拟主机： 一台服务器上配置多个IP地址，每个Ip地址都有特定的目录和配置。适合Ip地址充足的情况

1、[root@localhost root]# vi /etc/named.conf

zone "gr.org" IN {
type master;
file "gr.org.db";
allow-update { none; };
};

zone "170.168.192.in-addr.arpa" IN {
type master;
file "170.168.192.db";
};

2、正向区域数据库文件

[root@localhost root]# vi /var/named/gr.org.db

$TTL 86400
@ IN SOA  ns.gr.org.    root.gr.org.(
20140308 ;serial
8H       ;refresh
4M       ;retry
1W       ;expiry
1D  )    ;minimum
@      IN   NS      ns.gr.org.
ns     IN   A       192.168.170.1
host1  IN   A       192.168.170.1
host2  IN   A       192.168.170.2
host3  IN   A       192.168.170.3

反向区域数据库文件

[root@localhost root]# vi /var/named/170.168.192.db

$TTL 86400
@ IN SOA ns.gr.org.  root.gr.org.(
20150826
8H
4M
1W
1D)
IN   NS     ns.gr.org.
1         IN   PTR    ns.gr.org.
1         IN   PTR    host1.gr.org.
2         IN   PTR    host2.gr.org.
3         IN   PTR    host3.gr.org.

3、设置DNS客户端

[root@localhost root]# cat > /etc/resolv.conf
nameserver 192.168.170.4

service named start （启动服务）
如果已经启动，就 rndc reload (重启服务)

4、配置虚拟主机

[root@localhost conf.d]# vi /etc/httpd/conf.d/host_ip.conf

<VirtualHost 192.168.170.1:80>
DocumentRoot /var/www/host1
ServerName   host1.gr.org
</VirtualHost>

<VirtualHost 192.168.170.2:80>
DocumentRoot /var/www/host2
ServerName   host2.gr.org
</VirtualHost>

<VirtualHost 192.168.170.3:80>
DocumentRoot /var/www/host3
ServerName   host3.gr.org
</VirtualHost>

5、添加子接口的IP地址

[root@localhost conf.d]# ifconfig eth0:1 192.168.170.1

[root@localhost conf.d]# ifconfig eth0:2 192.168.170.2

[root@localhost conf.d]# ifconfig eth0:3 192.168.170.3

6、创建虚拟主机目录和测试主页

mkdir /var/www/host{1,2,3}

cd /var/www

echo “this host1” > host1/index.html

echo “this host2” > host2/index.html

echo “this host3” > host3/index.html

7、重启服务

service httpd restart

结果如下：













二、基于端口的虚拟主机：

1、在/etc/httpd/conf.d目录下 创建host_port.conf文件，添加以下内容

Listen  192.168.170.1:8000

Listen  192.168.170.1:8888

<VirtualHost  192.168.170.1:8000>

DocumentRoot   /var/www/host4

ServerName   host1.gr.org

</VirtualHost>

<VirtualHost  192.168.170.2:8888>

DocumentRoot   /var/www/host5

ServerName   host1.gr.org

</VirtualHost>

2、创建虚拟主机的工作目录和测试主页

mkdir  /var/www/host{4,5}

echo  “this host1(8000)” > /var/www/host4/index.html

echo  “this host1(8888)” > /var/www/host5/index.html

3、重启服务

service httpd restart

测试

三、基于名称的虚拟主机 (大多数用这种)

多个域名访问，都对应同一个IP地址

1、在 正向区域数据库文件 添加下面内容

music   IN  A  192.168.170.1

movie   IN  A  192.168.170.1

2、在 反向区域数据库文件 添加下面内容

1   IN   PTR    music.gr.org.

1   IN   PTR    movie.gr.org.

3、在/etc/httpd/conf.d目录下 创建host_domain.conf文件，添加以下内容

<VirtualHost   music.gr.org:80>

DocumentRoot   /var/www/music

ServerName   music.gr.org

</VirtualHost>

<VirtualHost   movie.gr.org:80>

DocumentRoot   /var/www/movie

ServerName   movie.gr.org

</VirtualHost>

4、创建虚拟主机的工作目录和测试主页

cd    /var/www

mkdir  music  movie

echo “this  music” >  music/index.html

echo “this  movie” >  movie/index.html

5、重启服务

rndc reload 或者 service named restart

service httpd start

6、测试
