MongoDB on-line environment according to and configuration (licensing mode start)

1 Create a file repo file

#vim/etc/yum.repos.d/mongodb-org-3.4.repo

[mongodb-org-3.4]

Name=mongodb Repository

baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/

Gpgcheck=1

Enabled=1

Gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

2 Installing the MongoDB package

#yum install-y mongodb-org

(optional) When new versions are available, yum updates these packages to prevent these "unintentional" updates by adding the following lines to the/etc/yum.conf file

Exclude=mongodb-org,mongodb-org-server,mongodb-org-shell,mongodb-org-mongos,mongodb-org-tools

3 Turn off SELinux

$sudo sed-i '/^[^#]/s/\ (selinux=\) \ ([a-z]\+\)/\1disabled/'/etc/sysconfig/selinux

$sudo sed-i ' s/^selinux=.*/selinux=disabled/'/etc/selinux/config

$sudo Setenforce 0

4 New Super Admin account

#mongo

>use Admin

Db.createuser (

{

User: "Superadmin",

PWD: "123456",

Roles: [{role: ' Useradminanydatabase ', db: ' admin '}]

}

)

>exit

5 Modify service start for licensing mode

#vim/lib/systemd/system/mongod.service

environment= "Options=-f/etc/mongod.conf--auth"

#systemctl Daemon-reload

#systemctl Restart Mongod

6 new database and administrator account

#mongo-U "superadmin"-P "123456"--authenticationdatabase "admin"

> Use DbName

Db.createuser (

{

User: "DbUser",

PWD: "123456",

Roles: [{role: ' Dbowner ', db: ' DbName '}]

}

)

7 Using the authorization connection string in the program

Client = new Mongoclient ("Mongodb://dbuser:[email protected]:27017/dbname");

8 MongoDB Maintenance

By default, users can only manipulate data in their own databases, even if they are super administrators.

If you need to manipulate other databases, you need to authorize the user of the database.

Such as

Use DbName

Db.auth ("DbUser", "123456")

The following illustration shows how a super-tube can view collection information in other databases.

Deleting a database

Use DbName

Db.dropdatabase ()

Delete User

Use DbName

Db.dropuser ("UserName")

View User

Db.getusers ()
