MongoDB權限管理二

mongodb配置文件以下：

[root@localhost ~]# cat /usr/local/mongodb/mongod.cnf 
bind_ip = 0.0.0.0
logpath=/data/mongodb/logs/mongodb.log
logappend = true
fork = true
#auth = true
port = 6068
dbpath=/data/mongodb/data
pidfilepath=/data/mongodb/mongod.pid

root超級管理員權限：
關閉mongod.cnf配置文件參數：auth
直接登陸mongo，設置登陸密碼：

mongo --host 127.0.0.1 --port 6068
use admin
db.createUser({user: 'root', pwd:'TdLLQSdHgyn#6689', roles:[{role: 'root', db: 'admin'}]});
db.auth("root","TdLLQSdH689")

關閉mongod
開啓mongod.cnf配置文件參數：auth =true

mongo --host 127.0.0.1 --port 6068
use admin
db.auth("root","TdLLQSdH689")

建立測試庫dbtest001，以及測試用戶testuser 對dbtest001庫有讀寫的權限

use dbtest001
db.createUser({user:"testuser",pwd:"testuser123",roles:[{role:"readWrite",db:"dbtest001"}]})

建立測試用戶testuser 對dbtest001庫有讀的權限：
db.createUser({user:"testuser01",pwd:"testuser123",roles:[{role:"read",db:"dbtest001"}]})

給測試庫插入一個集合chenji（所謂的表chenji）：

db.chenji.insert({"name":"小花","年級":"二年級","性別":"男","愛好":"學習"})
WriteResult({ "nInserted" : 1 })
> db.chenji.insert({"name":"花花","年級":"一年級","性別":"女","愛好":"唱歌"})
WriteResult({ "nInserted" : 1 })
> db.chenji.insert({"name":"小花","年級":"三年級","性別":"女","愛好":"打球"})
WriteResult({ "nInserted" : 1 })
> db.chenji.insert({"name":"小花","年級":"四年級","性別":"女","愛好":"畫畫"})
WriteResult({ "nInserted" : 1 })

查看當前庫下的用戶：

db.getUsers() 或者show users

> show users
{
    "_id" : "dbtest001.testuser",
    "userId" : UUID("f275fad5-ac4f-4dfa-aea6-af34ed93c3e1"),
    "user" : "testuser",
    "db" : "dbtest001",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "dbtest001"
        }
    ]
}

查看當前庫下某個用戶的權限：

db.getUser("testuser")
db.getUser("testuser01")

建立角色: db.createRole()
更新角色： db.updateRole()
刪除角色： db.dropRole()

得到某個角色信息: db.getRole()

> db.getRole("read")
{
    "role" : "read",
    "db" : "dbtest001",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}
> db.getRole("readWrite")
{
    "role" : "readWrite",
    "db" : "dbtest001",
    "isBuiltin" : true,
    "roles" : [ ],
    "inheritedRoles" : [ ]
}

刪除全部用戶: db.dropAllUsers()

刪除用戶：db.dropUsers("xxxxxx")

db.dropUser("testuser01")
true

將一個角色賦予讀寫給用戶： db.grantRolesToUser()

use dbtest001
db.grantRolesToUser('testuser01',[ { role : 'readWrite', db : 'dbtest001' } ] )

撤銷某個用戶的某個角色權限： db.revokeRolesFromUser()

> db.getUser("testuser01")
{
    "_id" : "dbtest001.testuser01",
    "userId" : UUID("d1fefe19-a94f-4300-8855-fd722f14e13f"),
    "user" : "testuser01",
    "db" : "dbtest001",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "dbtest001"
        }
    ]
}

撤回讀role讀寫權限:

> db.revokeRolesFromUser('testuser01',[ { role : 'readWrite', db : 'dbtest001' }])
> db.getUser("testuser01")
{
    "_id" : "dbtest001.testuser01",
    "userId" : UUID("d1fefe19-a94f-4300-8855-fd722f14e13f"),
    "user" : "testuser01",
    "db" : "dbtest001",
    "roles" : [ ]
}

更改密碼： db.changeUserPassword()

db.createUser({user:"testuser01",pwd:"testuser123",roles:[{role:"read",db:"dbtest001"}]})

修改密碼：

> db.changeUserPassword("testuser01","123456")

測試：使用原密碼登陸報錯以下：

[root@localhost ~]# mongo 127.0.0.1:6068/dbtest001 -u testuser01 -p 'testuser123'
MongoDB shell version v3.6.16
connecting to: mongodb://127.0.0.1:6068/dbtest001?gssapiServiceName=mongodb

使用新的密碼登陸成功

> show collections;
chenji
> db.chenji.find();
{ "_id" : ObjectId("5e0c80a8efc383349153386a"), "name" : "小花", "年級" : "二年級", "性別" : "男", "愛好" : "學習" }

查看當前庫下的表：

show collections
chenji

查看集合中全部的內容:

> db.chenji.find();
{ "_id" : ObjectId("5e0c80a8efc383349153386a"), "name" : "小花", "年級" : "二年級", "性別" : "男", "愛好" : "學習" }
{ "_id" : ObjectId("5e0c80c3efc383349153386b"), "name" : "花花", "年級" : "一年級", "性別" : "女", "愛好" : "唱歌" }

查看名字叫小花的記錄：

> db.chenji.find({"name":"小花"})
{ "_id" : ObjectId("5e0c80a8efc383349153386a"), "name" : "小花", "年級" : "二年級", "性別" : "男", "愛好" : "學習" }
{ "_id" : ObjectId("5e0c83c8efc383349153386c"), "name" : "小花", "年級" : "三年級", "性別" : "女", "愛好" : "打球" }
{ "_id" : ObjectId("5e0c83e9efc383349153386d"), "name" : "小花", "年級" : "四年級", "性別" : "女", "愛好" : "畫畫" }
