Tutorial Install Mongodb

Step-By-Step

1. Update System Package –

sudo apt update
sudo apt upgrade

2. Import MongoDB GPG Key –

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

3. Add MongoDB Repository -

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

*4. Reupdate your package system

sudo apt update

5. Install MongoDB

sudo apt install -y mongodb-org

6. Start MongoDB Services

sudo systemctl start mongod

7. Idk but is important

sudo systemctl enable mongod

8. Verify MongoDB Version

mongod --version

Add Authentication

This Step is optional but for production env i just read this shit

1. Logion to your mongodb shell

mongo

2. Create admin Database and add administrator users

use admin
db.createUser({
  user: "admin",
  pwd: "password123", // Ganti dengan password yang kuat
  roles: [{ role: "userAdminAnyDatabase", db: "admin" }]
})

3. Logout from mongodb shell

quit();

4. Edit the MongoDB configuration file to enable authentication
Open the MongoDB configuration file:

sudo nano /etc/mongod.conf

by default mongodb config will look like this

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1


# how the process runs
processManagement:
  timeZoneInfo: /usr/share/zoneinfo

#security:

#operationProfiling:

#replication:

you can change bindIp to 0.0.0.0 to acccess mongodb via public ip.

so back to the topic, we will add authentication on this shit
you can delete # on security and add this on the next line

security:
  authorization: "enabled"

so the final config is

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0


# how the process runs
processManagement:
  timeZoneInfo: /usr/share/zoneinfo

security:
  authorization: "enabled"

5. Restart MongoDB Services

sudo systemctl restart mongod

Authentication Test

1. Try connection without authentication (should fail):

mongo

try this command

use admin
show dbs

if you get error msg or dbs not showing, than is good, walla your mongodb security shit is upgrade. Techlead smile++ **2. Try connection with authentication **

mongo -u "admin" -p "password123" --authenticationDatabase "admin"

and try this command

use admin
show dbs

if you not get dbs list, then your configuration is failed. your techlead will fuck your head

thanks

Fix Error

if you add privilage for admin user then u see this error

you can follow this step

Check your mongodb log

Check the MongoDB logs for more information about why the service failed to start. This log is usually located at /var/log/mongodb/mongod.log:

sudo tail -n 50 /var/log/mongodb/mongod.log

if your mongodb log look like this

you can follow the next step

Check Configuration

Make sure the MongoDB configuration file (/etc/mongod.conf) has no errors. You can check the configuration file with a text editor like nano or vim:
```
sudo nano /etc/mongod.conf
```
Make sure that all configurations in the file are valid and appropriate. In particular, check the storage and systemLog sections to ensure the directories used actually exist and are accessible to MongoDB users.
Check Directory and File Permissions Make sure the MongoDB data directory has proper permissions and is owned by the mongodb user:
```
sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown -R mongodb:mongodb /var/log/mongodb
```
Delete Socket Files Manually
```
sudo rm /tmp/mongodb-27017.sock
```
Check /tmp Directory Permissions

Make sure the /tmp directory has the correct permissions. The /tmp directory must be accessible to all users:
```
sudo chmod 1777 /tmp
```
Restart MongoDB Service
```
sudo systemctl start mongod
```
