1.首先要创建数据库
use chunqiu
2.创建用户授予权限，在创建用户之前首先了解下mongodb中的role功能，那么admin数据库中有哪些role 呢？
查看role：
use admin
PRIMARY> show roles
{
"role" : "__system",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "backup",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "clusterAdmin",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "clusterManager",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "clusterMonitor",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "dbAdmin",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "dbAdminAnyDatabase",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "dbOwner",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "enableSharding",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "hostManager",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "read",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "readAnyDatabase",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "readWrite",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "readWriteAnyDatabase",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "restore",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "root",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "userAdmin",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "userAdminAnyDatabase",
"db" : "admin",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
那么chunqiu的库有哪些role呢？
use chunqiu
PRIMARY> show roles
{
"role" : "dbAdmin",
"db" : "chunqiu",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "dbOwner",
"db" : "chunqiu",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "enableSharding",
"db" : "chunqiu",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "read",
"db" : "chunqiu",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "readWrite",
"db" : "chunqiu",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
{
"role" : "userAdmin",
"db" : "chunqiu",
"isBuiltin" : true,
"roles" : [ ],
"inheritedRoles" : [ ]
}
3.看完了mongodb的role后是不是感觉豁然开朗？那么现在就创建用户吧：
use chunqiu
db.createUser(
{
user: "app_user",
pwd: "app#password",
roles:
[
{
role: "dbOwner", ##数据库权限的role选择dbOwner
db: "chunqiu" ##注意此处数据验证使用chunqiu库
}
]
}
)
如果要建只读账号：
use chunqiu
db.createUser(
{
user: "app_user_read",
pwd: "read#password",
roles:
[
{
role: "read", ##数据库权限的role选择read
db: "chunqiu"
}
]
}
)
查看已经创建的用户：
show users
修改密码：
db.changeUserPassword('app_user','password');
授予角色：
db.grantRolesToUser( "admin" , [ { role: "dbAdminAnyDatabase", db: "admin" } ])
取消角色：
db.revokeRolesFromUser( "admin" , [ { role: "dbAdminAnyDatabase", db: "admin" } ])
4.最后你可以把创建的账号和密码发给开发人员使用了。
