Hi

This is the script I use to start my b3 bot from linux.
It makes sure b3 is not already running before starting and does not kill the bot when you leave the console.

Note: I don't know is this work if you installed B3 as an egg.

Usage :
./bigbrotherbot <start|stop|restart|status>

when started, python does not give you back the console, so just hit the Enter Key to get it back. Then you can quit the console safely.


Copy/paste the following code into a file called 'bigbrotherbot' and make it executable (chmod +x bigbrotherbot)

Code:

#!/bin/bash

########### SETTINGS  ############

## the user that must be used to run the bot
USER=b3

## the big brother bot main config file
B3_CONFIGFILE="/home/urt/b3conf/b3.xml"

## where b3_run.py is located
B3_BIN="/home/urt/b3_run.py"

## where the python binary is located
PYTHON_BIN=/usr/bin/python

########### SETTINGS END ############

set -e
DEBUG=off
B3_OPTS="--config $B3_CONFIGFILE"
B3_PID_FILE="${HOME}/.b3-$(echo $B3_CONFIGFILE | tr '/' '_').pid"

if [ ! -f "$B3_CONFIGFILE" ]; then
  echo "ERROR: config file not found ($B3_CONFIGFILE)"

I'm using a very small restarter script from within screen. It automatically restarts the server/bot when it crashes (not when it hangs tho).

http://www.snt.utwente.nl/wiki/Howto_Server_Restarter

When you have multiple accounts that should be able to access the running processes for the gameserver and/or bot we have a more comprehensive set of scripts available, but it is quite a hassle to set it up. Interested how it looks? Take a look here: http://www.snt.utwente.nl/wiki/Howto_StartStopScripts

Hi

This the script I use to start my b3 bot from linux.
It makes sure b3 is not already running before starting and does not kill the bot when you leave the console.

Tomdesinto,

I just wanted to thank you for your script.  You have completely solved my b3 issues of having to manually restart it once a day.  Thank you again!

[Deemer]

Can we sticky this???

[Courgette]

glad it help you ...

[Huddex]

Is there anything similar for windows?

[Bakes]

not that I know of, but a quick autorestart script:

Code:

:TOP
path-to-b3_run eg C:\b3\b3_run.py
GOTO TOP

that will restart it
otherwise you could use firedaemon to do that for you.

[Platanos]

Nice Script, but the Ingame Command !restart kills BB is there an Option do put --restart in the script?

LG

[Courgette]

just set

Code:

B3_OPTS="--config $B3_CONFIGFILE --restart"

Trying to implement this but small issue: error: cannot execute b3_run.py

Trying to implement this but small issue: error: cannot execute b3_run.py

Same here, path is definately correct.

[v1ad]

@ mordy chmod u+x b3_run.py 

the chmod should be imported into the script. at least check 4 it.

[MordyT]

@ mordy chmod u+x b3_run.py 

the chmod should be imported into the script. at least check 4 it.

Will try and let you know. Thanks for the help!

Thanks, Im getting this :

ERROR: you have to run that script as b3

Thanks, Im getting this :

ERROR: you have to run that script as b3

you should make a user called b3 i think, or change

Code:

## the user that must be used to run the bot
USER=b3

to your unix username (not really safe to use root imho)
-edit-
hm i couldnt change it to my user, so  i did use root.
Gonna reboot now
-edit2-
works like a charm (using 3 b3 bots so far)
