Bebot on linux-vserver - absolute beginner here...

« on: June 13, 2008, 04:23:32 AM »

Well, might be a bit hard to help me since I don't know anything about linux but please give it a try Grin

I'm paying for a vserver, preconfigured with debian 4.0, and since this machine has not a lot to do I thought it would be nice to host our guildbot on it. That was the easy part of it...

Actually I think I did quite a good work until now, apache, php5 and mysql are working, bebot 0.4.3 is installed and working, even under different user than root (aorunner) and no superuser-rights needed.

My problem is:
I do need to have an open connection to the vserver to keep the chatbot running, as soon as I close the shell I'm using to start the bot it is shutting down. No message, just going off.
Is there a way to "install" the bot as a background task or how will I be able to keep the bot running without an open connection?

searching the forum would have gotten you an answer 4 hours ago.

a better key word would be "SCREENS"

There is either a script flying around here that starts bebot as a background service on linux.

Or install the tool "screen" as Dracutza said, it allows you to detach standard-input and -output from the normal shell. Basically something like the following:

Code:

screen -
php StartBot.php Botname

Then do CTRL+A D to detach.
To re-attach you only need to do screen -r.

ok here is the Instruction for screen with Debian

to install

Code:

apt-get install screen

now you can use 2 ways to start a new screen, i use 2nd cuz i have lots of bots
Start new screen with server address as name

Code:

screen -

Start new screen with "botname" as name ofc botname being what ever you want

Code:

screen -S botname

doing this will goto the window(if 1) or list them if more

Code:

screen -r

you can use the pid or the name or both together to goto a window, i pref the name since i use botname as name

Code:

screen -r botname

inside a window u can close it and end all actions inside with

Code:

exit

to detach the screen so you go back to main and it runs in back ground you do

Code:

[CTRL] + a then d

Thank you all, especially for the detailed howto

I found the script before posting here but it didn't work for me, in the thread is mentioned to start the bot with a perimeter ('php StartBot.php &') but this didn't work either.
The screen tool is working fine

@Dracutza
I did several forum searches before but they didn't show up any result according to my problem. But I'm still wondering how I should have come to the idea to search for "screen" or "screens", as I said I'm new to linux and I never heard of this tool before.

A search on "Linux" got me the screens data

Screen's -d flag is also handy. -d starts screen in detached mode.

screen -dS screenname php StartBot.php

attach with
screen -r screenname

Ocasionally you will find that your screen is still attached somewhere when you do screen -r. To work around this, use screen -Dr screenname.

The -D option forces detachment.

Screen has other nifty features like multiuser mode which will allow multiple users to attach to a shared screen.
