本篇文章為大家展示了MongoDB 中怎么修改用戶(hù)密碼，內(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過(guò)這篇文章的詳細(xì)介紹希望你能有所收獲。

    1、登陸mongodb數(shù)據(jù)庫(kù)集群主庫(kù)，創(chuàng)建超級(jí)管理用戶(hù)

db.createUser(  

{  

    user:"firstset",   

    pwd:"firstset",  

    roles:[{role:"userAdminAnyDatabase",db:"admin"}]  

}  

);  

    2、修改zhul的密碼，檢查mogodb進(jìn)程，注意端口號(hào)

ps -ef|grep mongod

mongo    10836     1  0 09:02 ?        00:00:03 mongod --dbpath /opt/mongo/data/dns_repset1 --port 10001 --replSet firstset --oplogSize 512 --rest --fork --logpath /opt/mongo/logs/firstset/firstset.log --logappend --nojournal --directoryperdb --keyFile /opt/mongo/keyfile/keyfile

mongo    10997  9767  0 09:09 pts/3    00:00:00 grep --color=auto mongod

    3、修改zhul的密碼，檢查當(dāng)前數(shù)據(jù)庫(kù)是否免密登陸

[mongo@mongo1 keyfile]$ mongo  --port 10001 

MongoDB shell version: 3.2.11-49-g52b68fa

connecting to: 127.0.0.1:10001/test

firstset:PRIMARY> show dbs

2019-10-24T09:09:31.298+0800 E QUERY    [thread1] Error: listDatabases failed:{

"ok" : 0,

"errmsg" : "not authorized on admin to execute command { listDatabases: 1.0 }",

"code" : 13

} :

_getErrorWithCode@src/mongo/shell/utils.js:25:13

Mongo.prototype.getDBs@src/mongo/shell/mongo.js:62:1

shellHelper.show@src/mongo/shell/utils.js:761:19

shellHelper@src/mongo/shell/utils.js:651:15

@(shellhelp2):1:1

firstset:PRIMARY> exit

bye

    通過(guò)驗(yàn)證，當(dāng)前數(shù)據(jù)庫(kù)試用了keyfile安全認(rèn)證校驗(yàn)，免密登陸會(huì)拒絕執(zhí)行任何命令

4、修改zhul的密碼，如果知曉被修改用戶(hù)的密碼可以使用賬號(hào)密碼登錄，也可以取消keyfile安全限制

免密登陸修改相關(guān)用戶(hù)的密碼后，再啟用keyfile安全認(rèn)證

[mongo@mongo1 keyfile]$ mongo  -u firstset  -p firstset  --port 10001

MongoDB shell version: 3.2.11-49-g52b68fa

connecting to: 127.0.0.1:10001/test

    5、驗(yàn)證密碼修改

--錯(cuò)誤的用戶(hù)名或者密碼登錄被拒絕

[mongo@mongo1 keyfile]$ mongo  -u firstset  -p firstset  --port 10001 

MongoDB shell version: 3.2.11-49-g52b68fa

connecting to: 127.0.0.1:10001/test

--使用正確的用戶(hù)名和密碼登錄后可以正常執(zhí)行操作

[mongo@mongo1 keyfile]$ mongo  -u firstset  -p rootroot --port 10001

MongoDB shell version: 3.2.11-49-g52b68fa

connecting to: 127.0.0.1:10001/test
