以下实验中PC1为服务器端，IP地址为192.168.10.10；PC2和PC3为客户机端, IP地址为192.168.10.20和192.168.10.30。
1、在PC1服务器端部署apache服务
[root@PC1 ~]# ifconfig | head -n 3
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.10.10 netmask 255.255.255.0 broadcast 192.168.10.255
inet6 fe80::20c:29ff:fe66:37f7 prefixlen 64 scopeid 0x20<link>
[root@PC1 ~]# yum install httpd -y

2、在PC1服务器端修改用户配置文件
[root@PC1 ~]# vim /etc/httpd/conf.d/userdir.conf
1 #
2 # UserDir: The name of the directory that is appended onto a user‘s home
3 # directory if a ~user request is received.
4 #
5 # The path to the end user account ‘public_html‘ directory must be
6 # accessible to the webserver userid. This usually means that ~userid
7 # must have permissions of 711, ~userid/public_html must have permissions
8 # of 755, and documents contained therein must be world-readable.
9 # Otherwise, the client will only receive a "403 Forbidden" message.
10 #
11 <IfModule mod_userdir.c>
12 #
13 # UserDir is disabled by default since it can confirm the presence
14 # of a username on the system (depending on home directory
15 # permissions).
16 #
17 #UserDir disabled
18
19 #
20 # To enable requests to /~user/ to serve the user‘s public_html
21 # directory, remove the "UserDir disabled" line above, and uncomment
22 # the following line instead:
23 #
24 UserDir public_html
25 </IfModule>
26
27 #
28 # Control access to UserDir directories. The following is an example
29 # for a site where these directories are restricted to read-only.
…………
3、在PC1服务器端创建两个测试用户
[root@PC1 ~]# cd /home/
[root@PC1 home]# ls
linuxprobe
[root@PC1 home]# useradd usertest1
[root@PC1 home]# useradd usertest2
[root@PC1 home]# echo redhat | passwd --stdin usertest1
Changing password for user usertest1.
passwd: all authentication tokens updated successfully.
[root@PC1 home]# echo redhat | passwd --stdin usertest2
Changing password for user usertest2.
passwd: all authentication tokens updated successfully.
[root@PC1 home]# ls
linuxprobe usertest1 usertest2
4、在PC1服务器端切换至测试用户usertest1，创建网站数据目录、修改权限
[root@PC1 home]# su - usertest1
[usertest1@PC1 ~]$ pwd
/home/usertest1
[usertest1@PC1 ~]$ mkdir public_html
[usertest1@PC1 ~]$ ls
public_html
[usertest1@PC1 ~]$ cd public_html/
[usertest1@PC1 public_html]$ ls
[usertest1@PC1 public_html]$ echo "welcome to 192.168.10.10 usertest1!" > index.html
-bash: !": event not found
[usertest1@PC1 public_html]$ echo "welcome to 192.168.10.10 usertest1\!" > index.html
[usertest1@PC1 public_html]$ ls
index.html
[usertest1@PC1 public_html]$ cat index.html
welcome to 192.168.10.10 usertest1\!
[usertest1@PC1 public_html]$ ll -d /home/usertest1
drwx------. 6 usertest1 usertest1 4096 Dec 16 23:21 /home/usertest1
[usertest1@PC1 public_html]$ chmod -R 755 /home/usertest1
[usertest1@PC1 public_html]$ ll -d /home/usertest1
drwxr-xr-x. 6 usertest1 usertest1 4096 Dec 16 23:21 /home/usertest1
5、在PC1服务器端切换至测试用户usertest2，创建网站数据目录、修改权限
[usertest1@PC1 public_html]$ su - usertest2
Password:
[usertest2@PC1 ~]$ pwd
/home/usertest2
[usertest2@PC1 ~]$ mkdir public_html
[usertest2@PC1 ~]$ ls
public_html
[usertest2@PC1 ~]$ cd public_html/
[usertest2@PC1 public_html]$ ls
[usertest2@PC1 public_html]$ echo " here is 192.168.10.10 usertest2" > index.html
[usertest2@PC1 public_html]$ ls
index.html
[usertest2@PC1 public_html]$ cat index.html
here is 192.168.10.10 usertest2
[usertest2@PC1 public_html]$ ll -d /home/usertest2
drwx------. 6 usertest2 usertest2 4096 Dec 16 23:24 /home/usertest2
[usertest2@PC1 public_html]$ chmod -R 755 /home/usertest2
[usertest2@PC1 public_html]$ ll -d /home/usertest2
drwxr-xr-x. 6 usertest2 usertest2 4096 Dec 16 23:24 /home/usertest2
6、在PC1服务器端重启apche服务
[usertest2@PC1 public_html]$ su - root
Password:
Last login: Wed Dec 2 16:39:39 CST 2020 on :0
[root@PC1 ~]# systemctl restart httpd
[root@PC1 ~]# systemctl enable httpd.service
ln -s ‘/usr/lib/systemd/system/httpd.service‘ ‘/etc/systemd/system/multi-user.target.wants/httpd.service‘
[root@PC1 ~]# systemctl status httpd.service

7、在PC1服务器端清空防火墙策略，并使其生效
[root@PC1 ~]# iptables -F
[root@PC1 ~]# service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
8、在PC2和PC3客户机端测试与PC1服务器端的网络连通性
[root@PC2 Desktop]# ifconfig | head -n 3
