权限问题导致这些错误。当您是管理员用户时，您正在尝试启动、停止或重新启动需要根权限的进程。 

要解决此问题，请以管理员身份使用 SSH 或 PuTTY 登录到 DPC 服务器，并运行以下命令成为 root 用户。 

su -

您必须是 root 用户才能启动、停止或重新启动服务，但您可以以管理员用户身份选中状态。

在 DPC 中，有两种方法可以启动、停止或重新启动服务：

• 从 /usr/local/dpc/bin 目录中，您可以运行以下命令来检查状态，启动、停止或重新启动所有 DPC 服务。 

admin@dpc01:~> dpc status
Version: 18.1.0-12
msm-ui-main: active
msm-monitor: active
msm-elg: active
mongod: active
rabbitmq-server: active
nginx: active
dpc-sso: active

• 您还可以使用以下命令启动、停止或重新启动所有服务：

dpc start
dpc stop
dpc restart

• 您也可以使用以下命令启动、停止或重新启动单个服务。

systemctl [restart|stop|start] msm-elg.service 
systemctl [restart|stop|start] msm-monitor.service 
systemctl [restart|stop|start] msm-ui-main.service 
systemctl [restart|stop|start] mongod
