PHP Code:

#!/bin/bash
while true
do
    LD_LIBRARY_PATH=. LD_PRELOAD=/path/to/libcod/libcod2_1_0.so /path/to/exe/cod2_lnxded +set fs_basepath /path/to/directory +set fs_homepath /path/to/directory +set fs_game yourmod +set net_ip 999.999.999.999 +set net_port 28960 +set developer 0 +set dedicated 2 +set sv_cracked 1 +exec config.cfg +map_rotate
    sleep 1
done

save as exec.sh

PHP Code:

---

#!/bin/bash

screen -S serv1 /path/to/exec.sh 


---

save as serv1.sh

Thanks man!

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

Code:

---

#!/bin/bash

screen -S test /exectest.sh

---

startexectest.sh

Code:

---

#!/bin/bash
while true
do
    LD_LIBRARY_PATH=. LD_PRELOAD=libcod2_1_0.so ./cod2_lnxded +set dedicated 2 +set net_ip 46.4.55.66 +set net_port 28972 +set sv_maxclients 52 +exec servertdm.cfg + exec pws.cfg +set fs_game test + set sv_cracked 1 + set logfile 2
    sleep 1
done

exectest.sh


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

Code:

---

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.

try screen -S test ./exectest.sh

Nah, put in the full path.

PHP Code:

---

#!/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.

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

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

Code:

---

#!/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).

Code:

---

#!/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/

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:
