“sudo service vsftpd”返回“未知工作：vsftpd”

Question

我在 ubuntu 14.04 上安装了 vsftpd，当我想停止或重新启动 vsftpd 服务时显示此消息，但服务状态没有任何反应！

root@ali-lap:/home/ali# service vsftpd restart
stop: Unknown job: vsftpd
start: Unknown job: vsftpd

我根据这篇文章清除了 vsftpd 并重新安装了它，但没有任何改变。

有任何想法吗？

Answer 1

我有一个类似的问题，发现它是由环境变量引起的。当您使用 时su，它会保留UPSTART_SESSION环境变量集（来自原始用户的环境），这会破坏事物。使用sudo或su -取消设置它，所以这些都可以工作：

$ sudo service vsftpd restart

$ sudo su
# service vsftpd restart

$ su -
# service vsftpd restart

$ su
# unset UPSTART_SESSION
# service vsftpd restart

Answer 2

尝试使用 sudo，这似乎是一个错误，或者您没有 root 的服务权限。

$ sudo service vsftpd status

应该有效，确实现在就在我眼前为我工作。
