MaNGOS Restarter ?

[Darkhunter]

Hello how can I make that if server(PC) is rebooted that MaNGOS will launch automatically ? I have ubuntu 9.10

it´s something in /etc/init.d but I don´t know what to do more...

[ilija]

Use search button

[Darkhunter]

used, but any restarters don´t work in init.d

[NickoNiklas]

used, but it doesn´t work

It does work.

I just searched for "restarter" and found lots of threads about restarters by just the title of the thread.

[Darkhunter]

yea it works a half ... when mangos crashes restarter start it again, but I need restarter, which will start when I start PC/Server where is MaNGOS

[perunio]

I take it you don't start up with screen(1)? If so, it's relatively easy:

#!/bin/bash

cd /opt/mangos/bin
nohup ./mangos-worldd > /dev/null 2>&1

[Darkhunter]

yes I know this, but I need to make it starting script ......as in windows are services ....

[freghar]

You can make cronjob for that ... or do something like

su mangosuser -c "command to run mangos"

from /etc/rc.local

[Darkhunter]

and what have I write to /etc/rc.local ? ...

dark@serverwow:~$ su mangosuser -c "cd /opt/mangos/bin && while :; do ./mangos-worldd; done"

Unknown id: mangosuser

Currently I have this python script

#! /usr/bin/python

import commands
import os
from sys import exit

# exit()

servername = 'mangos'

daemons = {
   'logon' : '/path/to/mangos/mangos-realmd',
   'world' : '/path/to/mangos/mangos-worldd'
}

for name, path in daemons.iteritems():
   if not os.path.basename(path) in commands.getoutput('ps -A'):
       os.chdir(os.path.dirname(path))
       os.system('screen -A -m -d -S ' + servername + '_' + name + '  sudo -u mangos_user ./' + os.path.basename(path))
       print 'Starting ' + name
   else:
       print name + ' is already running'

together with this cron job

  * *  *   *   *     python /path/to/restarter.py

I created file .py copied your script and change paths..saved it.. wrote in console:

dark@serverwow:~$    * *  *   *   *    python mangos.py
DBErrors.log: command not found

I see. No you don't need to add anything to /etc/rc.local, you could just drop your script into /etc/init.d. Call it `mangos' or something. Then in /etc/rc2.d, /etc/rc3.d and /etc/rc5.d create a symbolic link to it called `S99mangos'. The capital 'S' is important because it implies that you want to start the service. The number is an integer which defines in which order you want to run the script. Probably safe to run it at the 99th iteration as you need the system up and running anyway.

It is a cronjob not a bash command, and the way you tried to call it tells me you don't understand what you're doing tbh.

First of you need to edit the script so that it runs under the preferred user and uses the correct paths (I will make it easier to configure), after that you add that line I told you to your crontab file using "crontab -e" and of course correctly insert the path

[Darkhunter]

how to create link .. ?

[xeross155]

how to create link .. ?

What do you mean with a link ?

[Darkhunter]

Then in /etc/rc2.d, /etc/rc3.d and /etc/rc5.d create a symbolic link to it called `S99mangos'. - symbolic link.. Idk how to create this file type

[xeross155]

http://www.computerhope.com/unix/uln.htm

ln -s /path/to/the/script /etc/rc2.d/S99mangos

However I'm not sure if this is the best way to do it, I suggest using /etc/rc.local if available, or my method.

[Darkhunter]

okay it doesn´t work.. can u give me tutorial for ur script.. I ned also mangos-realmd launch.... I´m nooblike person with linux I know just compile...

[xeross155]

Darkhunter my script can restart as many realmd/worldd processes as you want, it's quite hard to explain it, perhaps we can chat on MSN or Yahoo or something, shoot me a PM with your address.

[Darkhunter]

yay, I have just icq.... 255341076

[xeross155]

Added you, don't show as online

[Darkhunter]

ur ICQ is ?..

[perunio]

Alright, I see where this needs to go. First, you'll need a script with which to start your daemons:

#!/bin/bash

cd /opt/mangos/bin
nohup ./mangos-realmd > /dev/null 2>&1
nohup ./mangos-worldd > /dev/null 2>&1

Then you need to copy said script (assuming it's called `mangos') to /etc/init.d:

sudo cp mangos /etc/init.d

After which you need to ensure that it is indeed able to execute, so set the least-most bit on the owner:

sudo chmod +x /etc/init.d/mangos

When this is done, you can use a handy wrapper present in Ubuntu to create the requisite links:

sudo update-rc.d mangos start 99 S .

That should do it.

[Darkhunter]

doesn´t work .. should I do sudo update-rc.d mangos start 99 S . for rc2.d rc3.d rc5.d ?

You can create a restarter with a few lines of bash

file : restarter.sh

#!/bin/bash

if (ps -C mangos-worldd )
   then echo "status : OK"
else
       echo "status : DOWN" 
       cd PATH_TO_YOUR_MANGOS/bin

       tar -czvf logs.tar.gz Server.log DBErrors.log Char.log

       #enable crashdumps
       ulimit -c unlimited

       screen -d -m -S session_name PATH_TO_YOUR_MANGOS/bin/mangos-worldd
fi

and execute this script using cron

crontab -e

*/1 * * * * cd /home/youruser/scripts/restarter;./restarter.sh

Cron checks the process every minute, and restart it, if it crashed.

This script is for the world process, you can easily adapt it for realmd
