sudo yum install -y mongodb-org

如果 找不到 repo、执行一下操作

vi /etc/yum.repos.d/mongodb-org-3.4.repo

db.removeUser(username)

db.grantRolesToUser(username, roles, writeConcern)

db.revokeRolesFromUser()

db.getUser(username, args)

db.getUsers()

db.auth( , )

System Collections

admin.system.roles

admin.system.users

admin.system.version

.system.namespaces

.system.indexes

.system.profile

.system.js

Connection String URI Format
