Last Chaos global server control script

[xHypnosiaa]

This script is a simple global controller for a Last Chaos server setup.

It lets you start, stop, restart, and check the status of all server components with one command.

It uses GNU screen, so every server runs in its own detached screen session and keeps running after you disconnect.

---

What the script does



Starts each LC server in the correct folder





Runs each server in a dedicated screen session





Prevents starting the same server twice





Redirects all output to log files





Lets you manage everything with one command




---

Your servers must be located like this:

/home/lastchaos/
├─ Connector/
├─ Helper/
├─ SubHelper/
├─ Messenger/
├─ LoginServer/
├─ GameServer1/
├─ Billing/
└─ logs/

Otherwise, adjust the script if you want it to respect and use your own environment.

Each server folder must contain either:



a run script

or





an executable named like the folder (ex: Connector, Helper, etc.)




---

How to use it

Make the script executable:

chmod +x server_start.sh

Then use it :

./server_start.sh start # start all servers
./server_start.sh stop # stop all servers
./server_start.sh restart # restart all servers
./server_start.sh status # show server status

---

Logs

All logs are automatically written to:

/home/lastchaos/logs/

One log file per server:

Connector.log
Helper.log
GameServer1.log
...

---

Screen sessions

Each server runs in a screen named like:

LC_Connector
LC_GameServer1
...

To attach:

screen -r LC_GameServer1

---

Notes for beginners



Make sure screen is installed





Run the script as the same user that owns the server files





If a server doesn’t start, check its log first




---

Script can be reworked, updated and modified to fits your need, but this is a solid base and would be useful for most beginners.
