mongodb管理Security and Authentication
mongdb自己也提供了验证机制,如果不验证是无法访问数据库对象,一个数据可以有多个用户,用户的权限也可以各不相同,下面具体介绍一下。
> use admin ----登录到超级管理员
>db.addUser("root", "abcd");
{
"_id" : ObjectId("4eaf58af769d879418d93191"),
"user" : "root",
"readOnly" : false,
"pwd" : "1a0f1c3c3aa1d592f490a2addc559383"
}
创建了一个超级用户,这个用户可以访问任何数据库,权限最大
> use test
switched to db test 切换到test数据库
> db.addUser("test_user", "efgh");
{
"user" : "test_user",
"readOnly" : false,
"pwd" : "6076b96fc3fe6002c810268702646eec"
}
> db.addUser("read_only", "ijkl", true);
{
"user" : "read_only",
"readOnly" : true,
"pwd" : "f497e180c9dc0655292fee5893c162f1"
}
以上创建两个用户,test_user和read_only,不同的是,read_only用户只有只读权限
> use test
switched to db test
> db.test.find();
error: { "$err" : "unauthorized for db [test] lock type: -1 " }
> db.auth("read_only", "ijkl");
1
> db.test.find();
{ "_id" : ObjectId("4bb007f53e8424663ea6848a"), "x" : 1 }
> db.test.insert({"x" : 2});
unauthorized
> db.auth("test_user", "efgh");
1
> db.test.insert({"x": 2});
> db.test.find();
{ "_id" : ObjectId("4bb007f53e8424663ea6848a"), "x" : 1 }
{ "_id" : ObjectId("4bb0088cbe17157d7b9cac07"), "x" : 2 }
以上例子可以看到没有验证用户登录,对数据库读写操作均不能,read_only用户只能查询,不能插入,但是test_user用户验证登录后就可以插入了。
如果这时,show dbs,还是报错,因为test_user 不是admin用户,所以没有权限。
> use admin
switched to db admin
> db.auth("root", "abcd");
1
> show dbs
admin
local
test
验证了超级用户就可以做相关操作
创建的这些用户都存在创建时数据库下面一个叫system.users的集合里面,如果要移除一个user,例如移除test_user
> db.auth("test_user", "efgh");
1
> db.system.users.remove({"user" : "test_user"});
> db.auth("test_user", "efgh");
0
启用验证登录:如果是配置文件启动server端,里面可以加入auth = true ,如果是跟参数启动mongod 后面记得跟--auth。

This article introduces how to configure MongoDB on Debian system to achieve automatic expansion. The main steps include setting up the MongoDB replica set and disk space monitoring. 1. MongoDB installation First, make sure that MongoDB is installed on the Debian system. Install using the following command: sudoaptupdatesudoaptinstall-ymongodb-org 2. Configuring MongoDB replica set MongoDB replica set ensures high availability and data redundancy, which is the basis for achieving automatic capacity expansion. Start MongoDB service: sudosystemctlstartmongodsudosys

This article describes how to build a highly available MongoDB database on a Debian system. We will explore multiple ways to ensure data security and services continue to operate. Key strategy: ReplicaSet: ReplicaSet: Use replicasets to achieve data redundancy and automatic failover. When a master node fails, the replica set will automatically elect a new master node to ensure the continuous availability of the service. Data backup and recovery: Regularly use the mongodump command to backup the database and formulate effective recovery strategies to deal with the risk of data loss. Monitoring and Alarms: Deploy monitoring tools (such as Prometheus, Grafana) to monitor the running status of MongoDB in real time, and

It is impossible to view MongoDB password directly through Navicat because it is stored as hash values. How to retrieve lost passwords: 1. Reset passwords; 2. Check configuration files (may contain hash values); 3. Check codes (may hardcode passwords).
