MongoDB Setup account and password

First, install MongoDB

1. Environment configuration:

I. Operating system: CentOS release 6.8 (Final)

Cat /etc/redhat-release

II. Computer Type: x86_64

uname -M

2. Download the corresponding MongoDB version

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.6.4.tgz

3. Unzip the MongoDB database

tar -zxvf mongodb-linux-x86_64-rhel62-3.6. 4. tgz

4. Start MongoDB

mkdir -p/data/db    # CREATE DATABASE data store directory

[Email protected] opt]# Cd/opt/mongodb/bin  

[[email protected] bin]#./mongod  # Boot MONGO Server service, default port: 27017, local connection allowed by default

Second, configure the account number and password

1. Turn on authentication

MongoDB default installation After the completion, only allow local connection, and do not need to use any account password to directly connect MongoDB, so it is easy to be black, let pay some bitcoins, so in order to avoid these

Necessary trouble, so we need to set an account password for MONGO;

[[email protected] bin]#./mongod--auth  # Enable authentication

2. Create an administrator user

>Use adminswitched to DB admin> Db.createuser ({User:"Admin",pwd:"Password", roles:["Root"]}) Successfully added User: {"User":"Admin","Roles": ["Root"] }

3. Authentication Login

> Db.auth ("admin""password")
