How To Host Telegram Bot on Scaleway

1. Lets create a Scaleway Account first!

Link: https://console.scaleway.com/register

Enter required details and signup with Scaleway !

Card verification is required for signup! You'll be charged some amount for verification and the same will be refunded within few hours. So don't worry. 

2. Making an instance in Scaleway

Choose appropriate plan!

Creating a SSH key
Download PuTTY: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

*Create a new SSH Public key and copy paste it in Instance config page.
*Save it as our Private key.
*Create instance.

3. Connecting to the instance!

- Connecting to instance with our SSH key

        hostname : root@ipaddress

- You'll be logged in as a root user!

- Create a new user with sudo privileges ( cause it's better that way)

        sudo adduser  <newusername>

        sudo usermod -aG  sudo  <newusername>

        su - <newusername>

- Now whenever you login to your instance, change to your user by;

        su - <newusername>

Some required commands,

         sudo apt update && sudo apt upgrade

NOTE : Use Enter key to run your commands. Use right click to paste your copied command into terminal.

4. Setting up your repository

Configure Marie Bot Repo;

Clone the source code of Marie

Source code : https://github.com/prgofficial/Marie-2.0-English

Create config.py file from sample_config.py

#Bot Token: from Bot Father
#Owner ID: from Rose ( /id )
#Owner username: Any name
#Database URL: Install Postgres server in our Instance and get

5. Install and setup a Postgres Server

Connect to your instance, then run;
         sudo apt-get update
         sudo apt-get install postgresql postgresql-contrib

Give sudo permission to user
         sudo usermod -aG sudo postgres

Set a new password
         sudo passwd postgres

Password will be invisible, don't worry!

Login to Postgres
         su - postgres

Create new user for psql
         createuser --interactive --pwprompt

# enter a name for user
# enter a password for user
# give superuser power

You can give any name and password!!

Create a database and assign user
        createdb -O <username> <newdbname>

;

Allow remote access
         nano /etc/postgresql/12/main/postgresql.conf

Uncomment, and change the value;

#listen_addresses = 'localhost'
to
listen_addresses = '*'


This will allow Postgres connections from anyone.
USE ctrl + o and press enter to save the file and ctrl + x to exit the editor


Allow Connections from everyone 

         nano /etc/postgresql/12/main/pg_hba.conf

Modify this section;

# IPv4 local connections:

host all all 127.0.0.1/32 md5

to;

# IPv4 local connections:

host all all 0.0.0.0/0 md5

this will allow anyone to connect to your db using the username and password!
USE ctrl + o and press enter to save the file and ctrl + x to exit the editor

Allow port 5432
         sudo ufw allow 5432/tcp

Restart postgres to apply changes
         sudo systemctl restart postgresql

Now, your DB Uri will be;
        postgres://username:pw@hostname:port/dbname

6. Hosting Marie repo

connect again using putty or;

press ctrl + a + d to go back to your user from our current screen
