MongoDB权限

1. 添加用户

MongoDB shell version: 1.8.2
connecting to: 127.0.0.1:30000/test
>
>
>
> use admin
switched to db admin
> db.addUser('admin','admin')
{
                 "user" : "admin",
                 "readOnly" : false,
                 "pwd" : "7c67ef13bbd4cae106d959320af3f704"
}
>

2. 带上--auth参数后重启

$MONGODB_HOME/bin/mongod --fork --logpath=$MONGODB_HOME/logs/mongodb.log --dbpath=$DATA_PATH --port=$MONGODB_PORT --auth

3. 测试

MongoDB shell version: 1.8.2
connecting to: 127.0.0.1:30000/test
>
> use admin
switched to db admin
> show collections
Sat Aug    6 11:16:45 uncaught exception: error: {
                 "$err" : "unauthorized db:admin lock type:-1 client:127.0.0.1",
                 "code" : 10057
}
switched to db admin
> db.auth('admin','admin')
1
> show collections
system.indexes
system.users
>

没有执行 db.auth('admin','admin')以前会报错，说是未受权

4. Java客户端调用也须要使用用户名和密码，只需简单地加上一句

db.authenticate( "admin", "admin".toCharArray());

5. 在admin下添加的用户是超级管理员，能够访问任何数据库，用超级管理员能够为单个数据库添加用户，这个用户只能访问他所在的数据库

> use test
switched to db test
> db.addUser( "test", "test")
{
                 "user" : "test",
                 "readOnly" : false,
                 "pwd" : "a6de521abefc2fed4f5876855a3484f5" }

6. 在未受权的状况下，依然能够执行db.shutdownServer()停掉节点因此运行mongodb的服务器端口必定要严格受权访问
