2、在PC1服务器端修改配置文件，绑定IP地址和主机域名
[root@PC1 ~]# ifconfig | head -n 5
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

3、在PC1服务器端创建保存三个网站数据的目录以及首页内容
[root@PC1 ~]# mkdir -p /home/wwwroot/aaaaa
[root@PC1 ~]# mkdir -p /home/wwwroot/bbbbb
[root@PC1 ~]# mkdir -p /home/wwwroot/ccccc
[root@PC1 ~]# echo "here is aaaaa" > /home/wwwroot/aaaaa/index.html
[root@PC1 ~]# echo "here is bbbbb" > /home/wwwroot/bbbbb/index.html
[root@PC1 ~]# echo "here is ccccc" > /home/wwwroot/ccccc/index.html
4、在PC1服务器端修改Apache服务的主配置文件，写入三个基于主机域名的虚拟主机网站参数
[root@PC1 ~]# vim /etc/httpd/conf/httpd.conf
…………
112 #
113 <VirtualHost 192.168.10.10>
114 DocumentRoot "/home/wwwroot/aaaaa"
115 ServerName "www.aaaaa.com"
116 <Directory "/home/wwwroot/aaaaa">
117 AllowOverride None
118 Require all granted
119 </Directory>
120 </VirtualHost>
121 <VirtualHost 192.168.10.10>
122 DocumentRoot "/home/wwwroot/bbbbb"
123 ServerName "www.bbbbb.com"
124 <Directory "/home/wwwroot/bbbbb">
125 AllowOverride None
126 Require all granted
127 </Directory>
128 </VirtualHost>
129 <VirtualHost 192.168.10.10>
130 DocumentRoot "/home/wwwroot/ccccc"
131 ServerName "www.ccccc.com"
132 <Directory "/home/wwwroot/ccccc">
133 AllowOverride None
134 Require all granted
135 </Directory>
136 </VirtualHost>
137 #
…………
5、在PC1主机中重启apache服务
[root@PC1 ~]# systemctl restart httpd
[root@PC1 ~]# systemctl status httpd | head -n 5
httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled)
Active: active (running) since Thu 2020-12-17 21:59:52 CST; 12s ago
Main PID: 4385 (httpd)
Status: "Total requests: 0; Current requests/sec: 0; Current traffic: 0 B/sec"
6、在PC1服务器端关闭防火墙策略
[root@PC1 ~]# iptables -F
[root@PC1 ~]# service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
7、在PC1主机中修改网站数目目录及首页数据的SELinux上下文值
[root@PC1 ~]# ls -ldZ /var/www/html/
drwxr-xr-x. root root system_u:object_r:httpd_sys_content_t:s0 /var/www/html/
[root@PC1 ~]# ls -ldZ /home/wwwroot/aaaaa/
drwxr-xr-x. root root unconfined_u:object_r:home_root_t:s0 /home/wwwroot/aaaaa/
[root@PC1 ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/aaaaa
[root@PC1 ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/aaaaa/*
[root@PC1 ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/bbbbb
[root@PC1 ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/bbbbb/*
[root@PC1 ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/ccccc
[root@PC1 ~]# semanage fcontext -a -t httpd_sys_content_t /home/wwwroot/ccccc/*
[root@PC1 ~]# restorecon -Rv /home/wwwroot/
restorecon reset /home/wwwroot context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:user_home_dir_t:s0
restorecon reset /home/wwwroot/aaaaa context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0

restorecon reset /home/wwwroot/ccccc context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
restorecon reset /home/wwwroot/ccccc/index.html context unconfined_u:object_r:home_root_t:s0->unconfined_u:object_r:httpd_sys_content_t:s0
[root@PC1 ~]# ls -ldZ /home/wwwroot/aaaaa/
drwxr-xr-x. root root unconfined_u:object_r:httpd_sys_content_t:s0 /home/wwwroot/aaaaa/
8、在PC1服务器端修改SELinux的域服务

9、在PC2客户机端测试PC1服务器端网络连通性
[root@PC2 ~]# ifconfig | head -n 3
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.10.20 netmask 255.255.255.0 broadcast 192.168.10.255
inet6 fe80::20c:29ff:fe25:bb3e prefixlen 64 scopeid 0x20<link>
[root@PC2 ~]# ping -c 3 192.168.10.10

rtt min/avg/max/mdev = 0.205/0.265/0.309/0.043 ms
[root@PC2 ~]# ping -c 3 www.aaaaa.com
ping: unknown host www.aaaaa.com
[root@PC2 ~]# ping -c 3 www.bbbbb.com
ping: unknown host www.bbbbb.com
## 说明PC2端无法实现域名解析
10、在PC1服务器端测试基于域名的虚拟主机功能
以上实验实验只实现了基于主机域名部署多个网站在同一主机的验证（PC2客户机无法解析域名）。
