报错内容：


The unit files have no installation config (WantedBy=, RequiredBy=, Also=, Alias= settings in the [Install] section, and DefaultInstance= for template units). This means they are not meant to be enabled using systemctl.

修改文件’/usr/lib/systemd/system/rc-local.service’，末尾增加：


[Install]
WantedBy=multi-user.target

其他的服务也是一样的。
