You have to work overtime tonight, just sort out the permission context configuration of mongodb. After installing and configuring a set of mongodb, you need to create a corresponding database and user password for the developer, so how to set the permission?

1. The first step is to create a database

Use chunqiu

two。 To create a user to grant permissions, first learn about the role function in mongodb before creating a user, so what role are there in the admin database?

View 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": []

}

So what is the role in chunqiu's library?

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. Do you feel enlightened after watching mongodb's role? So create a user now:

Use chunqiu

Db.createUser (

{

User: "app_user"

Pwd: "app#password"

Roles:

[

{

Role: "dbOwner", # # Select dbOwner for the role of database permissions

Db: "chunqiu" # # Note here data validation uses the chunqiu library

}

]

}

)

To set up a read-only account:

Use chunqiu

Db.createUser (

{

User: "app_user_read"

Pwd: "read#password"

Roles:

[

{

Role: "read", # # Select read for the role of database permissions

Db: "chunqiu"

}

]

}

)

View the users that have been created:

Show users

Change the password:

Db.changeUserPassword ('app_user','password')

To grant a role:

Db.grantRolesToUser ("admin", [{role: "dbAdminAnyDatabase", db: "admin"}])

Cancel the role:

Db.revokeRolesFromUser ("admin", [{role: "dbAdminAnyDatabase", db: "admin"}])

4. Finally, you can send the created account and password to the developer to use.
