MongoDB3.2如何升级至3.4.6,相信很多没有经验的人对此束手无策,为此本文总结了问题出现的原因和解决方法,通过这篇文章希望你能解决这个问题。

MongoDB 升级测试步骤:

1、MongoDB版本升级顺序3.2->3.4->3.6->4.0 不能跨版本升级

2、升级到3.4后,您不能降级到3.2.7或更早版本。您只能降级到3.2.8或更高版本

3、先升级所有副本集中的Secondary

4、将Primary节点降级为Secondary节点

5、升级Primary

6、MongoDB3.2升级到3.4,登录后查看版本信息若还是3.2,执行db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )

7、MongoDB3.4升级到3.6,登录后查看版本信息若还是3.4,执行db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )

8、MongoDB3.6升级到4.0,登录后查看版本信息若还是3.6,执行db.adminCommand( { setFeatureCompatibilityVersion: "4.0" } )

###只在升级到4.0执行###

  cfg = rs.conf();

  cfg.protocolVersion=1;

  rs.reconfig(cfg);

将Primary升级至3.4.6

将Primary节点降级为Secondary节点,有两种方式,一种是rs.stepDown() , 另一种是通过修改优先级来修改Primary

shard1:PRIMARY> rs.stepDown()

通过优先级来修改PRIMARY

shard1:PRIMARY> config=rs.conf()      //查看当前配置,存入config变量中

shard1:PRIMARY> config.members[0].priority = 50         //修改config变量,第1组成员的优先级为50

shard1:PRIMARY> rs.reconfig(config)             //配置生效

shard1:PRIMARY> rs.config()                   //查看当前配置
