## mongodb的用户管理（认证管理）
用户分三种
全局用户
数据库对应用户
只读用户
### 创建全局用户（全局用户只能在admin账户下创建）
创建了一个名为zhuima,密码为zhuima的全局账户
[root@redis ~]# hostname
redis.unix178.com
[root@redis ~]# mongo
MongoDB shell version: 2.4.6
connecting to: test
> show dbs
local0.078125GB
> use admin
switched to db admin
> db.addUser("zhuima","zhuima")
{
"user" : "zhuima",
"readOnly" : false,
"pwd" : "214c77cbc6bc7d26f28022c30496223d",
"_id" : ObjectId("53cbcb3cc5761ac13c7f6614")
}
>### 开启配置文件中的auth = true选项
[root@redis ~]# sed -n ‘/auth/p‘ /etc/mongodb.conf #noauth = true #auth = true auth = true [root@redis ~]#
### 重启mongodb进行验证 这里可以看到我们进行show的时候提示没权限
[root@redis ~]# mongo
MongoDB shell version: 2.4.6
connecting to: test
> show dbs
Sun Jul 20 14:02:01.765 listDatabases failed:{ "ok" : 0, "errmsg" : "unauthorized" } at src/mongo/shell/mongo.js:46
>### test数据库是默认进入的目录，如果你不想进入test数据库，mongo 后面跟上--nodb即可
### 想要切换到全局用户时，必须先要进入admin数据库才可以
[root@redis ~]# mongo
MongoDB shell version: 2.4.6
connecting to: test
> use admin
switched to db admin
> db.auth("zhuima","zhuima")

...

}### 可以看出nick用户只能对zhuima这个数据库进行权限操作

>### 用户管理后记
多用help 类似db.help()
看官方文档，然后把命令都敲一遍
多实践才是王道
## 来一些系统的基本的查看管理命令
### help指令
多用help，你会发现原来世界那么美好
> help
db.help() help on db methods
db.mycoll.help() help on collection methods
sh.help() sharding helpers
rs.help() replica set helpers
help admin administrative help
help connect connecting to a db help
help keys key shortcuts
help misc misc things to know
help mr mapreduce
show dbs show database names
show collections show collections in current database
show users show users in current database
show profile show most recent system.profile entries with time >= 1ms
show logs show the accessible logger names
show log [name] prints out the last segment of log in memory, ‘global‘ is default
use <db_name> set current database
db.foo.find() list objects in collection foo
db.foo.find( { a : 1 } ) list objects in foo where a == 1
it result of the last line evaluated; use to further iterate
DBQuery.shellBatchSize = x set default number of items to display on shell
exit quit the mongo shell
> db.help()
