mongodb 集群关闭

本地用三台机器部署了mongo集群，需要测试能否切换primary和secondary。
于是在关闭primary的时候出现了以下问题：

repset:PRIMARY> use admin
switched to db admin
repset:PRIMARY> db.shutdownServer()
2016-11-14T10:07:51.912+0800 E QUERY    [thread1] Error: shutdownServer failed: {
    "ok" : 0,
    "errmsg" : "shutdown must run from localhost when running db without auth",
    "code" : 13
} :
_getErrorWithCode@src/mongo/shell/utils.js:25:13
DB.prototype.shutdownServer@src/mongo/shell/db.js:302:1

解决方法

[grid@mongohost1 mongodb2.6]$ ./bin/mongo --port 33333
