Quick deployment with GNU screen¶
GNU screen is an handy tool which lets you create shell sessions detached from your current session. This means they will keep running even if you log out from the server. With it, you’re able to run your bot in the exact same way you’re running it in your development machine, without worrying about anything else.
This deployment method is not recommended for real-world deployments, because it doesn’t try to keep alive your bot if it crashes. It’s explained here because this method is useful if you just want to test how the bot runs on the server.
The first thing you need to do is to install the tool. On Debian/Ubuntu you can execute the following command (from root):
$ apt-get install screen
Instead, on CentOS/Fedora you need to run this command (from root):
$ yum install screen
Perfect, you now have GNU screen installed. You can create a new screen with
the following command (replace
screen_name with the name you want to assign
to the screen):
$ screen -S screen_name
And you’re into your screen. Now, install botogram (if you
didn’t do that before) and run your bot in it, as you would do on your local
machine. You can exit the screen anytime by pressing
CTRL+A and then
If you want to resume it later, run the following command:
$ screen -x screen_name
Remember that if you don’t enable the multiuser feature, you can’t attach to screens of other users, so be sure to be logged in with the same account as you started the screen.
