httpd 的設定檔 /etc/httpd/conf/httpd.conf，預設設定中只要加入你的網頁伺服器網域名稱就可以了。

[root@kvm3 ~]# vi /etc/httpd/conf/httpd.conf 
[root@kvm3 ~]# grep kvm3 /etc/httpd/conf/httpd.conf 
ServerName kvm3.deyu.wang:80

設定開機啟動 httpd 服務，並立即啟動。

[root@kvm3 ~]# systemctl enable --now httpd.service 
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service →
 /usr/lib/systemd/system/httpd.service.

查詢 httpd 服務狀態。
