2. 启动ntp服务出错
[root@http-stress2 ~]# systemctl status ntp
Unit ntp.service could not be found.
3. 检查systemd服务列表
输入如下命令检查systemd是否存在ntp服务:
systemctl list-unit-files --type=service
由上图可知,systemd提供了ntp服务,重启systemd服务:
systemctl daemon-reload
4. 启动ntp服务
操作如下所示:
[root@http-stress2 ~]# systemctl start ntpd
[root@http-stress2 ~]#
[root@http-stress2 ~]# systemctl status ntpd
