[CoD2/CoD4] Server auto-restart

[filthy_freak_]

Hi man,

My server keeps shutting down, because of segmentation errors. When you first helped me with setting up libcod on my vps, you made some script that auto restarts the server when it's offline. Can you send me that script again? It was extremely usefull.

Thanks man!

I get the error No such file or directory, while the files are there.

#!/bin/bash

screen -S test /exectest.sh
startexectest.sh


#!/bin/bash
while true

sleep 1
done
exectest.sh


Both placed in same folder as from where I run the command

bash startexectest.sh

I get the error No such file or directory, while the files are there.

#!/bin/bash

screen -S test /exectest.sh

bash startexectest.sh

Have you tried to execute it with 'sh'?
Where did you place exectest.sh? In / (root) or home directory (~/exectest.sh)?

Edit: if startexectest.sh and exectest.sh are in the same directory then you remove \ from your start script.

[IzNoGoD]

I get the error No such file or directory, while the files are there.

#!/bin/bash

screen -S test /exectest.sh
startexectest.sh

try screen -S test ./exectest.sh

[filthy_freak_]

Nah, put in the full path.



#!/bin/bash

screen -S test /home/username/cod2/exectest.sh


That way the file can be executed from any directory without issues.

Also make sure the file permissions are setup correctly.

chmod -R 755 ./CoD2

Edit: Also if you're using root then you're doing it wrong.

[Ni3ls]

Works! But when will the server start again? When there is a script error? Or when somebody did /killserver?

[fabio]

You will need to query the server for 100% working autorestart :O

Here's a script I hacked together back in 2013 but it should still work.

Install steps:
1. Save the script as mon.sh
2. Adjust the serverport to reflect your own config (28960 = default)
3. Make the file executable and adjust the paths (file locations). Note: If you do not have a start.sh script to start your server, see below, I included one.
4. Schedule it as a crontab every minute, like so:
* * * * * /path/to/watchdog/script/mon.sh >/dev/null 2>&1



#!/bin/bash
# COD2 Process Monitor - Server 1
# Restart COD2 Server When It Goes Down

#Restart Command
RESTART="/path/to/start/script/start.sh"

#path to pgrep command
PGREP="/usr/bin/pgrep"

# find httpd pid
$PGREP -f '.*28960'

if [ $? -ne 0 ] # if server not running
then
# restart server
$RESTART
fi


This script works with multiple COD servers on the same physical server. Just save multiple copies of the script and adjust the server port.

In case you are not using a bash script to start your server, here's an example that uses screen to run the server in the background. Save it as start.sh, adjust paths and make it executable (no need to schedule in crontab).


#!/bin/bash
cd /home/cod2/cod2/

# Start server now!
screen -A -m -d -S cod2pub /home/cod2/cod2/cod2_lnxded +set net_port 28960 +exec server.cfg +fs_homepath /home/cod2/cod2/

[CaptainSlow]

Also, if you're running a Windows server, I suggest looking at 'FireDaemon' which allows you to run any executable as a service. This means that if the exe (i.e. the gameserver) crashes, it automatically restarts it, along with other handy features:

screen -A -m -d -S cod2pub /home/cod2/cod2/cod2_lnxded +set net_port 28960 +exec server.cfg +fs_homepath /home/cod2/cod2/


So I want to use this script. I just the exact same script, but with other startup, port and screenname.
I start it with

bash ./autoboot.sh
The screen is created, but the server is not started inside the screen, but in the "main" Putty window.
How to fix this?

[kung foo man]

screen -AmdS cod2pub
screen -S cod2pub -p 0 -X stuff "/home/cod2/cod2/cod2_lnxded +set net_port 28960 +exec server.cfg +fs_homepath /home/cod2/cod2/
"


Works ever, on all versions. ^^

[Ni3ls]

This is still not working.

Even with a sleep between creating the screen and going in the screen.


screen -AmdS hjsd
sleep 1
screen -x hjsd
cd /home/olger/HIGHJUMP/
export LD_LIBRARY_PATH="/home/olger/HIGHJUMP"
export LD_PRELOAD="/home/olger/HIGHJUMP/libcod2_1_0_kungv2.so /home/olger/HIGHJUMP/limit_fake.so /home/olger/HIGHJUMP/limit_challenge.so"
./cod2_lnxded_1_0a_va_loc_128 +set dedicated 2 +set net_ip 46.4.55.66 +set net_port 28958 +set sv_maxclients 52 +exec serversd.cfg + exec pws.cfg +set fs_game sd2 + set sv_cracked 1 + set logfile 2
So this is what happens:
Screen is created, wait 1 second, I go inside the screen. Nothing happens now. I detach the screen (going to "main" window in putty), server starts

[kung foo man]

You can't go "into" the screen, you just can append commands to it via screen -x hjsd -p 0 -X stuff "echo hi\n"

Just put this into a hjsd.sh:




cd /home/olger/HIGHJUMP/
export LD_LIBRARY_PATH="/home/olger/HIGHJUMP"
export LD_PRELOAD="/home/olger/HIGHJUMP/libcod2_1_0_kungv2.so /home/olger/HIGHJUMP/limit_fake.so /home/olger/HIGHJUMP/limit_challenge.so"
./cod2_lnxded_1_0a_va_loc_128 +set dedicated 2 +set net_ip 46.4.55.66 +set net_port 28958 +set sv_maxclients 52 +exec serversd.cfg + exec pws.cfg +set fs_game sd2 + set sv_cracked 1 + set logfile 2


Then your screen stuff (no need for sleep):




screen -AmdS hjsd
screen -S hjsd -p 0 -X stuff "./hjsd.sh
"

What is meant by this "stuff" part? :P

I still have some random server stops, so im trying to use this script. Somehow I get an error that i can't preload the libcod.so file

ERROR: ld.so: object '/home/olger/HIGHJUMP/libcod2_1_0_newest.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.


However, when I use the "normal" start, there is no error at all. What can be the error? All directories are set correctly and cod2_lnxded and the autoboot are in the same folder as well

[kung foo man]

Since you export LD_PRELOAD globally, it tells the LD linker to inject libcod.so into *every* process called in your shell script (cat, tail, mkdir and whatnot). So the linker is now supposed to link a 32bit library into 64bit processes, which simply errors out

This might work, just fit the script so it only sets LD_PRELOAD for the cod2_lnxded (and remove the export LD_PRELOAD line on top of that shell script)

LD_PRELOAD=/home/olger/HIGHJUMP/libcod2_1_0_newest.so ./cod2_lnxded "$@"

What am i doing wrong?

[kung foo man]

Looks like your LD_PRELOAD is still global from a previous test, restart putty (and/or restart screen session) and try this:

Okay server is running.
What kind of crashed will activate the script?
"killserver" doesnt do anything

[kung foo man]

just type quit?
