执行jps
连接7180 cloudera-manager UI界面,无法连接
执行/opt/cloudera-manager/cm-5.14.1/etc/init.d/cloudera-scm-server status
提示:cloudera-scm-server dead but pid file exists
删除.pid文件rm /opt/cloudera-manager/cm-5.14.1/run/cloudera-scm-server.pid
执行启动命令:/opt/cloudera-manager/cm-5.14.1/etc/init.d/cloudera-scm-server start
查看状态,jps
看到Main就可以取访问7180了,进去之后所有服务,主机可能都报未知运行状态,重启的话也可能报错,具体如何处理,记录在下一篇博文中.
