Connect and authenticate
|
# connect
mongo mongodb://localhost:27017
# alias
mongo
# connect and authenticate, use an environment variable to hide the password
mongo "mongodb://user:${DBPASSWORD}@<host>:<port>/admin?authSource=admin"
|
Authenticate
|
db.auth("username", "pwd")
db.auth("username", passwordPrompt())
|
Database
|
|
// list the databases
show dbs
// drop the current database
db.dropDatabase()
|
Backup and restore
|
|
# restore the backup folder dump to the local mongodb instance
mongorestore dump/
|
don't know what to do with file while restore
This may happen because the mongorestore command point to a backup sub-folder not to the backup folder itself.

// list the users of the current database
db.getUsers()
db.runCommand('usersInfo')
// get info of a specific user
db.getUser("tom", { showCredentials: true, showPrivileges: true, showAuthenticationRestrictions: true })
// create admin
use admin
db.createUser(
{
user: "admin",
pwd: "mypwd",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]

// create a user for the demo database
