Port Utilization Requirements

The following ports must be open on the server for the program to function.

Type	Application	Description	Port
TCP	MongoDB	Database access port	27017
TCP	Postgres	Database access port	5432
TCP	Postgres	Database access port	6115

The ports can be opened as follows:

SSH into the Media Server.
- Use command:
  ssh username@server-ip
- Enter the ssh password and press Enter.
Use command:
```
su
```
Enter the root user's password

Run the following commands:

sudo iptables -A INPUT -p tcp -m tcp --dport 5432 -j ACCEPT
sudo iptables -A INPUT -p tcp -m tcp --dport 27017 -j ACCEPT
sudo iptables -A INPUT -p tcp -m tcp --dport 6115 -j ACCEPT
sudo iptables-save

Media Server PostgreSQL Configuration

SSH into the Media Server.
- Use command:
  ssh username@server-ip
- Enter the ssh password and press Enter.
Use command:
```
su
```
Enter the root user's password
Navigate to the Postgresql folder.
- cd /etc/postgresql/<version>/main/
- Where <version> is the version of Postgresql being used.
Open the file postgresql.conf.
- vi postgresql.conf
- Scroll down to find the line #listen_addresses='*' and remove the # symbol.
Save and exit by :
- Press the Esc key.
- Enter the phrase :wq to save and exit.
Open the file pg_hba.conf.
- vi pg_hba.conf

Scroll down to the bottom and add the line:

host    all             all             0.0.0.0/0            md5

Save and exit by :
- Press the Esc key.
- Enter the phrase :wq to save and exit.
Restart the Postgresql service:
- systemctl restart postgresql

Create MongoDB database

SSH into the Media Server.
- Use command:
  ssh username@server-ip
- Enter the ssh password and press Enter.
Use command:
```
su
```
Enter the root user's password.
Run command:
```
systemctl enable mongod
```
Open the MongoDB config file:
```
vi /etc/mongod.conf
```
Locate the field bindIp and set its value to the IP address of the current server. find the #network interfaces line as example given below
```
# network interfaces
net:
  port: 27017
  bindIp: <Your server IP>
```
Note the value of the port field as well.
Run command:
```
systemctl restart mongod
```
Run command:
```
mongosh --host HOST --port PORT
```
1. Where HOST is the value of the bindIp field in Step 3.
2. PORT is the value of the port field in Step 4.
In the following text replace USER and PASS with your choice of username and password respectively, then copy and paste it in the Mongo CLI opened in the previous step, and press enter:
```
use recording-link-activities
db.createUser(
  {
    user: "USER",
    pwd: "PASS",
    roles: []
  }
)
```
Confirm the user creation with this command. after creating the user with step 10 above. run this command
```
db.getUsers()
```
Exit with the command:
```
exit
```

Container Deployment

SSH into the Media Server.
- Use command:
  ssh username@server-ip
- Enter the ssh password and press Enter.
Use command:
```
