思路:
1.为了保证数据的一致性,必须先关闭应用的写服务。
2.提升要升级为Primary节点的Secondary节点的优先级。

操作如下:

点击(此处)折叠或打开

  1. arps:PRIMARY> config=rs.conf()                //查看当前配置,存入config变量中。
  2. arps:PRIMARY> config.members[2].priority =//修改config变量,第三组成员的优先级为3.
  3. arps:PRIMARY> rs.reconfig(config)             //配置生效                       
  4. ......
  5. ......
