mongodb配置文件如下：
[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.pidroot超级管理员权限：
关闭mongod.cnf配置文件参数：auth
直接登录mongo，设置登录密码：
mongo --host 127.0.0.1 --port 6068
use admin
db.createUser({user: 'root', pwd:'TdLLQd689', roles:[{role: 'root', db: 'admin'}]});
db.auth("root","TdLLQSdH689")关闭mongod
开启mongod.cnf配置文件参数：auth =true
mongo --host 127.0.0.1 --port 6068
use admin
db.auth("root","TdLLQH689")创建测试库dbtest001，以及测试用户testuser 对dbtest001库有读写的权限
use dbtest001
db.createUser({user:"testuser",pwd:"testuser123",roles:[{role:"readWrite",db:"dbtest001"}]})
创建测试用户testuser 对dbtest001库有读的权限：
db.createUser({user:"testuser01",pwd:"testuser123",roles:[{role:"read",db:"dbtest001"}]})给测试库插入一个集合chenji（所谓的表chenji）：
db.chenji.insert({"name":"小花","年级":"二年级","性别":"男","爱好":"学习"})
WriteResult({ "nInserted" : 1 })
> db.chenji.insert({"name":"花花","年级":"一年级","性别":"女","爱好":"唱歌"})
WriteResult({ "nInserted" : 1 })
> db.chenji.insert({"name":"小花","年级":"三年级","性别":"女","爱好":"打球"})
WriteResult({ "nInserted" : 1 })
> db.chenji.insert({"name":"小花","年级":"四年级","性别":"女","爱好":"画画"})
WriteResult({ "nInserted" : 1 })查看当前库下的用户：
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"
}
]
}查看当前库下某个用户的权限：
db.getUser("testuser")
db.getUser("testuser01")创建角色:db.createRole()
更新角色：db.updateRole()
删除角色：db.dropRole()
获得某个角色信息:db.getRole()
> db.getRole("read")
{
"role" : "read",
"db" : "dbtest001",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
> db.getRole("readWrite")
{
"role" : "readWrite",
"db" : "dbtest001",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}删除所有用户:db.dropAllUsers()
删除用户：db.dropUsers("xxxxxx")
db.dropUser("testuser01")
true
将一个角色赋予读写给用户：db.grantRolesToUser()
use dbtest001
db.grantRolesToUser('testuser01',[ { role : 'readWrite', db : 'dbtest001' } ] )撤销某个用户的某个角色权限：db.revokeRolesFromUser()
> db.getUser("testuser01")
{
"_id" : "dbtest001.testuser01",
"userId" : UUID("d1fefe19-a94f-4300-8855-fd722f14e13f"),
"user" : "testuser01",
"db" : "dbtest001",
"roles" : [
{
"role" : "readWrite",
"db" : "dbtest001"
}
]
}撤回读role读写权限:
> 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" : [ ]
}更改密码：db.changeUserPassword()
db.createUser({user:"testuser01",pwd:"testuser123",roles:[{role:"read",db:"dbtest001"}]})修改密码：
> db.changeUserPassword("testuser01","123456")测试：使用原密码登录报错如下：

{ "_id" : ObjectId("5e0c83e9efc383349153386d"), "name" : "小花", "年级" : "四年级", "性别" : "女", "爱好" : "画画" }查看当前库下的表：
show collections
chenji
查看集合中所有的内容:
> db.chenji.find();
{ "_id" : ObjectId("5e0c80a8efc383349153386a"), "name" : "小花", "年级" : "二年级", "性别" : "男", "爱好" : "学习" }
{ "_id" : ObjectId("5e0c80c3efc383349153386b"), "name" : "花花", "年级" : "一年级", "性别" : "女", "爱好" : "唱歌" }查看名字叫小花的记录：
> db.chenji.find({"name":"小花"})
{ "_id" : ObjectId("5e0c80a8efc383349153386a"), "name" : "小花", "年级" : "二年级", "性别" : "男", "爱好" : "学习" }
{ "_id" : ObjectId("5e0c83c8efc383349153386c"), "name" : "小花", "年级" : "三年级", "性别" : "女", "爱好" : "打球" }
{ "_id" : ObjectId("5e0c83e9efc383349153386d"), "name" : "小花", "年级" : "四年级", "性别" : "女", "爱好" : "画画" }到此为止, 关于MongoDB中的权限管理有了一个基础的认识, 但是对于具体的使用方法还是需要多加巩固和练习，如果想了解更多相关内容，请关注创新互联行业资讯。
