MongoDB Compilation Installation

Installing MongoDB
1. Download

Latest: Https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.6.4.tgz

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.2.8.tgz

mkdir Usr/local/mongodb

2, decompression  
Tar zxvf mongodb-linux-x86_64-rhel70-3.2.8.tgz 
MV mongodb-linux-x86_64-rhel70-3.2.8/usr/ local/ 
MV mongodb-linux-x86_64-rhel70-3.2.8 mongodb 
CD mongodb/

mkdir db 
mkdir logs 
CD bin/ 
3, edit configuration file:  
Vim mongodb.conf 
Enter the following: 
dbpath=/usr/local/mongodb/db 
logpath=/usr/local/mongodb/logs/mongodb.log 
bind_ip=0.0.0.0  
port=27017 
fork=true 
Nohttpinterface=true

4, create a new account:  
Groupadd mongodb 
Useradd mongodb-g mongodb 
CD. /.. / 
Chown-r Mongodb:mongodb MongoDB

5, start:  
/usr/local/mongodb/bin/mongod-f/usr/local/mongodb/bin/mongodb.conf

6, set boot auto-start mongodb 
vi/etc/rc.d/rc.local 
/usr/local/mongodb/bin/mongod–config/usr/local/ mongodb/bin/mongodb.conf

To enter MongoDB Shell mode:
/usr/local/mongodb/bin/mongo
To view a list of databases:
Show DBS
To view the current DB version:
Db.version ();

7. Increase Administrator Privileges:

useradminanydatabase This role has the ability to assign roles and users, but there is no flaw  
Root This is super Administrator  
ReadWrite has read and write permission  

Enter Shell mode:
/usr/local/mongodb/bin/mongo

Use admin//Switch to admin database

db.createuser ( 
{ 
User: "root",  
pwd: "llh2018",  
Roles:[{role: "Root", DB: " Admin "}] 
} 
);

db.createuser ( 
{ 
User: "Mongoroot",  
pwd: "llh2018",  
Roles:[{role: " Useradminanydatabase ", DB:" admin "}] 
} 
);  
verify where to go to the DB where the user is registered:  
Db.auth (" Mongoroot "," testMongoDB2016 ")  
You can then use this Mongoroot account to create a database management account:  
Db.createuser ({User:" Llh ", pwd: "llh2018", roles:[{"role": "ReadWrite", "db": "Admin"}]})

Exit Mongod service first

use admin 
Db.auth ("root", "testMongoDB2016")  
Db.shutdownserver ()  
and open mongod without authentication  
use admin 
Db.dropuser ("Lelaohui")  
Db.system.version.update ({"_id": "Authschema"},{$ set:{"CurrentVersion": 3})  
Db.createuser ({User: "Lelaohui", pwd: "123456", roles:[{"role": "ReadWrite", "db ":" Admin "}]})  
to start MongoDB again as authentication

needs to be executed under the shell:  
use testdb 
Db.createuser ({User: "hhq163", pwd: " test123456 ", roles:[{" role ":" ReadWrite "," db ":" TestDB "}]})

Vim/usr/local/mongodb/bin/mongodb.conf
Add the following line at the end of the file:
Auth=true

8. Close the database server:
Use admin
Db.shutdownserver ()

If the account security certification, you must first certification:
Use admin
Db.auth ("root", "testMongoDB2016")
Db.shutdownserver ()
