配置

配置文件修改后,让 SystemD 重新加载配置文件

1
sudo systemctl daemon-reload

检查服务状态

1
sudo systemctl status nfs-mount-239

启动服务

1
sudo systemctl start nfs-mount-239

停止服务

1
sudo systemctl stop nfs-mount-239

设置开机启动

1
sudo systemctl enable nfs-mount-239

禁止开机启动

1
sudo  systemtl disable  nfs-mount-239

检查开机启动配置结果

1
sudo systemctl is-enabled nfs-mount-239

enable、disable或static，这里的 static 它是指对应的 Unit 文件中没有定义[Install]区域，因此无法配置为开机启动服务。
