执行 systemctl restart httpd 报错

[root@localhost home]# systemctl restart httpd

Job for httpd.service failed. See ‘systemctl status httpd.service‘ and ‘journalctl -xn‘ for details.

报错这个问题

经多次排查，这次是yum 配置上出现问题

[root@localhost ~]# vim /etc/yum.repos.d/rhcsa.repo
[rhcsa]
name=rhcsa
baseurl=file:///media/cdrom
enable=1
gpgcheck=0

改为：
[root@localhost ~]# vim /etc/yum.repos.d/rhcsa.repo
[rhcsa]
name=rhcsa
baseurl=file:///media/cdrom
enabled=1
gpgcheck=0

enable改为enabled
