centos7 Unit https.service failed to load: No such file or directory.



CentOS7.1，安装http后，设置httpd为自动启动

#systemctl enable httpd.service

# systemctl start https.service
Failed to start https.service: Unit https.service failed to load: No such file or directory.

错误的原因是没有重新加载/usr/lib/systemd/system目录下的service导致的。

# systemctl daemon-reload   （执行这个操作就能解决问题）
# systemctl restart httpd.service

重启操作成功
