mongodb- 管理

配置文件(外部配文件置):

mongod --config D:\mongodb\mongodb.config

 mongodb.config文件内容:

 port = 20000
dbpath = D:/mongodb/dbs
logpath = D:/mongodb/logs.log
logappend = true

正确停止MongoDB:

mongo -port 20000
use admin
db.shutdownServer();

安全认证:

  1.添加用户

   db.addUser(username, password,[ readOnly=false])

    [ readOnly=false]参数可选,如果为true,用户只有查询权限。

   admin数据库下面添加的用户  被视为超级用户(管理员)。

2.用户认证
 db.auth(username, password)

3.重启服务端,加入 --auth命令选项  开启安全检查

mongod --dbpath D:/mongodb/db  --port 20000 --logpath = D:/mongodb/logs.log --logappend --auth

 例子:

1. 添加一个超级用户:

a.添加用户

>mongo -port 20000
> use admin
switched to db admin
> db.addUser("admin","admin123");
{ "n" : 0, "connectionId" : 4, "err" : null, "ok" : 1 }
{
        "user" : "admin",
        "readOnly" : false,
        "pwd" : "6f09f2f35e3a5e225af66fe3868e4fb7",
        "_id" : ObjectId("50114eb027e4ae802c6bda45")
}
>

b.认证用户

> use admin
switched to db admin
> db.auth("admin","admin123");
1

c.重启服务端 加入--auth参数

登录后不能正常查询

>mongo --port 20000 test
MongoDB shell version: 2.0.4
connecting to: 127.0.0.1:20000/test
> db.test.find();
error: {
        "$err" : "unauthorized db:test lock type:-1 client:127.0.0.1",
        "code" : 10057
}
>

d.使用用户名 密码登录

>mongo --port 20000 admin  -u admin -p
MongoDB shell version: 2.0.4
Enter password:
connecting to: 127.0.0.1:20000/admin
> use test
switched to db test
> db.test.find();
>

2.添加一个普通用户

> use test
switched to db test
> db.addUser("abc","abc123");
{ "n" : 0, "connectionId" : 9, "err" : null, "ok" : 1 }
{
        "user" : "abc",
        "readOnly" : false,
        "pwd" : "30fc2d5cc077f71cc81d3c82afc9d361",
        "_id" : ObjectId("501157ed1d2319c203e2e8d3")

认证:

> db.auth("abc","abc123");
1

用户名 密码登录

mongo --port 20000 test  -u abc -p
MongoDB shell version: 2.0.4
Enter password:
connecting to: 127.0.0.1:20000/test
> db.test.find();

查询用户

 db.system.users.find()

删除用户:

db.system.users.remove({user:"admin"});

限制ip访问:

使用--bindip 参数, 只能被--bindip参数指定的ip地址访问.

如:mongod --bindip localhost

数据文件备份:

>mongodump -port 20000 -d test -u admin -p-d test

备份的数据库名称会在当前目录下创建一个dump目录,用于存放备份出来的文件,当然也可以(-o)指定备份存放的目录。

mongodump -port 20000 -d test -o c:/ -u admin -p

mongodump --help 查看其他选项

数据恢复:

>mongorestore -port 20000 -d test --directoryperdb c:/test/  --drop -u admin -p

--directoryperdb指定备份的目录

--drop 恢复的时候先删除

例:

a,先删除test数据库

> use test;
switched to db test
> db.dropDatabase();
{ "dropped" : "test", "ok" : 1 }
> show dbs;
admin   0.03125GB
local   (empty)

b.恢复

mongorestore -port 20000 -d test --directoryperdb c:/test/  --drop -u admin -p
