Tutorial

Important Note Uptime: ~24/7 Downtime: ~ 2 Days (sometimes due to high traffic of API)

Rough Steps

1. Create EC2 Instance using t2-Micro
2. Generate your putty private file (.ppk) using puttyGen.exe
3. Connect to your EC2 Instance with putty.exe using ubunutu@IPv4 address
4. Create an extra screenn session using "screen -S New"
5. After running your python file, detach the screen using "Ctrl + A + D"
6. Logout of terminal using "Ctrl + A + D"
7. To reconnect to your Bot console, use "screen -r {window name that you created before}
8. Ctrl + C to terminate the bot and update it (remember to git pull/push)

Common Errors

1. Error: Running py file

python3 -m tg_bot_service (without .py extension)

2. Error: Importing ParseMode from Telegram

pip install python-telegram-bot --upgrade

3. Error: KeyError"Coin"

This is due to hitting the Rate Limit of CryptoCompare API.

Add throttle function to before each API function to reduce the frequency of calls. I use this ratelimit library

4. Error: pip3 module not found

This happens if you terminate your EC2 instance and relaunch a new server. You need to re-setup your ubuntu installation.

sudo apt-get update

sudo apt-get install python3-pip

git clone "github repo"

cd "folder"

pip3 install -r requirements.txt

pip install "any other missing modules"

python3 -m tg_bot_service

Putty Shotcuts

1. Ctrl + A + D (to detach screen)
2. screen -list (to see all sessions)
3. screen -dr SCREENID (to reattached screen)
