3. Start the httpd service
[root@node ~]# systemctl enable --now httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
4. Add an IP address
1. Check the original IP
[root@node conf.d]# ifconfig ens33
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.3.166 netmask 255.255.255.0 broadcast 192.168.3.255

2. Add IP address
[root@node conf.d]# ip addr add 192.168.3.164/24 dev ens33
[root@node conf.d]# ip add |grep ens33
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

Five, modify the httpd configuration file
1. Create the root directory of three virtual hosts
mkdir -p /var/www/web{1,2,,3}
2. Add the content of the webpage file
[root@node conf.d]# mkdir -p /var/www/web{1,2,,3}
[root@node conf.d]# echo "web1 service" > /var/www/web1/index.html
[root@node conf.d]# echo "web2 service" > /var/www/web2/index.html
[root@node conf.d]# echo "web3 service" > /var/www/web3/index.html
Six, ip-based virtual host
1. Modify the httpd service configuration file
[root@node conf.d]# cat ip.conf
#Listen 8181

ServerName web1.huawei.com
DocumentRoot /var/www/web1
</VirtualHost>
<VirtualHost 192.168.3.164:80>
ServerName web2.huawei.com
DocumentRoot /var/www/web2
</VirtualHost>
#<VirtualHost *:8181>
#ServerName web3.huawei.com
#DocumentRoot /var/www/web3
#</VirtualHost>
2. Restart the httpd service
systemctl restart httpd
3. IP access effect
[root@node conf.d]# curl 192.168.3.166
web1 service
[root@node conf.d]# curl 192.168.3.164
web2 service
Seven, port-based virtual host
1. Modify the httpd configuration file
[root@node conf.d]# cat port.conf
Listen 8181

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#192.168.3.166 web1.huawei.com
192.168.3.166 web2.huawei.com
192.168.3.164 web3.huawei.com
3. Restart the httpd service
systemctl restart httpd
4. Access test results
[root@node conf.d]# curl web2.huawei.com:8181
web2 service
[root@node conf.d]# curl web3.huawei.com:8181
web3 service
5. Access test based on domain name
[root@node conf.d]# curl web3.huawei.com
