如何禁用ntpd?

我正在VM中运行Ubuntu。 如何禁用ntpd?

要停止ntpd:

sudo /etc/init.d/ntp stop 

要么

 sudo service ntp stop 

为了防止它在启动时启动:

 sudo update-rc.d -f ntp remove 

如果已安装,请卸载ntpd。 您仍将安装ntpdate。 (很难删除。)通过在/etc/default/ntpdate添加exit 0来阻止它执行。

使用systemd,这两个命令是:

 sudo systemctl stop ntp sudo systemctl disable ntp 

输出(我认为警告可以忽略)

 ntp.service is not a native service, redirecting to systemd-sysv-install Executing /lib/systemd/systemd-sysv-install disable ntp insserv: warning: current start runlevel(s) (empty) of script `ntp' overrides LSB defaults (2 3 4 5). insserv: warning: current stop runlevel(s) (1 2 3 4 5) of script `ntp' overrides LSB defaults (1). insserv: warning: current start runlevel(s) (empty) of script `ntp' overrides LSB defaults (2 3 4 5). insserv: warning: current stop runlevel(s) (1 2 3 4 5) of script `ntp' overrides LSB defaults (1). 

校验:

 systemctl is-enabled ntp 

产量
