重启服务

systemctl restart cloudera-scm-server.service
systemctl restart cloudera-scm-agent.service

查看服务是否启动，显然结果是failed

systemctl status cloudera-scm-server.service

查看异常

journalctl -xe

去看服务日志

发现是这个位置错误

SqlExceptionHelper - Table ‘metastore.CM_VERSION’ doesn’t exist

用navicat打开数据后发现确实在metastore库下是没有CM_VERSION这张表的，但是在scm下有，然后我就自己在metastore库里面建一个一样的，不知道有没有用

当时我记得配数据库的时候是用scm的，不知为啥变成metastore了，现在改回来

再重启服务

systemctl restart cloudera-scm-server.service

还是有问题

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactoryBean': FactoryBean threw exception on object creation; nested exception is java.lang.RuntimeException: ScmActive at bootup: Failed to validate the identity of Cloudera Manager.

 vi /etc/default/cloudera-scm-server 

再重启服务

systemctl restart cloudera-scm-server.service

终于启动起来了，然后登录http://xxx:7180/cmf/home 去看哪些服务没起的就手动起就完了
