linux系统部署apache服务（测试不同inux主机访问网站）
以下实验中服务器端为PC1，IP地址为192.168.10.10 ；客户机端分别为PC2和PC3，IP地址分别为192.168.10.20和192.168.10.30
1、在PC1服务器端安装apache服务
[root@PC1 ~]# ifconfig | head -n 3 ## 查看IP
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服务器端启动apache服务
[root@PC1 ~]# systemctl start httpd
[root@PC1 ~]# systemctl enable httpd
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
[root@PC1 ~]# systemctl status httpd

3、在PC2和PC3客户机端测试与PC1的网络连通性
[root@PC2 Desktop]# 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 Desktop]# ping -c 3 192.168.10.10
PING 192.168.10.10 (192.168.10.10) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.236/0.269/0.326/0.040 ms
[root@PC3 Desktop]# ifconfig | head -n 3
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.10.30 netmask 255.255.255.0 broadcast 192.168.10.255

[root@PC3 Desktop]# ping -c 3 192.168.10.10
PING 192.168.10.10 (192.168.10.10) 56(84) bytes of data.
64 bytes from 192.168.10.10: icmp_seq=1 ttl=64 time=0.316 ms

3 packets transmitted, 3 received, 0% packet loss, time 2002ms
rtt min/avg/max/mdev = 0.177/0.241/0.316/0.058 ms
4、在PC2和PC3客户机端测试PC1的apache服务（均无法连接）
5、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 ]
6、在PC2和PC3客户机端测试PC1的apache服务（都可以访问）
7、在PC1服务器端修改apache服务网站的首页数据
[root@PC1 ~]# cd /var/www/html/
[root@PC1 html]# ls
[root@PC1 html]# echo "this is a test ! welcome to 192.168.10.10" > index.html
[root@PC1 html]# ls
index.html
[root@PC1 html]# cat index.html
this is a test ! welcome to 192.168.10.10
8、 在PC2和PC3客户机端测试PC1主机的配置的首页数据效果（PC1的首页数据配置生效）
以上实验实现了服务器端PC1配置Apache服务，PC2和PC3客户机端访问网站的效果（web服务）。
