首先报错信息如下
[root@izgt88z6l1kvd7z create]# systemctl start httpd
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
然后我查看了一下httpd的状态
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Mon 2020-05-11 03:44:25 CST; 1min 47s ago
Docs: man:httpd(8)

我注意到有这么一条(98)Address already in use: AH00072: make_sock: could not bind to addres...0.0:80显示80被占了
然后我又查看了一下网络，果然是nginx占用了80端口
没办法，那就只能修改一下httpd的默认端口了
[root@izgt88z6l1kvd7z create]# vim /etc/httpd/conf/httpd.conf
：x 保存退出
再次开启httpd服务
[root@izgt88z6l1kvd7z create]# systemctl start httpd
[root@izgt88z6l1kvd7z create]# echo $?
0
考虑到阿里防火墙，开启一下
[root@izgt88z6l1kvd7z create]# firewall-cmd --zone=public --add-port=8080/tcp --permanent
success
[root@izgt88z6l1kvd7z create]# firewall-cmd --reload
success
访问一下
成功！
