MongoDB 3.2 升級至 3.4.6
MongoDB 升級測試步驟：
1、MongoDB版本升級順序3.2->3.4->3.6->4.0 不能跨版本升級
2、升級到3.4後，您不能降級到3.2.7或更早版本。您只能降級到3.2.8或更高版本
3、先升級所有副本集中的Secondary
4、將Primary節點降級為Secondary節點
5、升級Primary
6、MongoDB3.2升級到3.4，登入後檢視版本資訊若還是3.2，執行db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )
7、MongoDB3.4升級到3.6，登入後檢視版本資訊若還是3.4，執行db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } )
8、MongoDB3.6升級到4.0，登入後檢視版本資訊若還是3.6，執行db.adminCommand( { setFeatureCompatibilityVersion: "4.0" } )
###只在升級到4.0執行###
cfg = rs.conf();
cfg.protocolVersion=1;
rs.reconfig(cfg);
