Simple guide – How to use the build deployment script
This script is used to deploy the latest compiled build to your Last Chaos server folders.
It automates what most people usually do by hand.
---
What the script does
When you run it, the script will:
Take the latest compiled build
Backup the existing files before replacing them
Copy the new binaries to the correct server directories
Apply permissions 777 on deployed files
Overwrite old builds in a clean and repeatable way
This avoids manual copy/paste and reduces deployment mistakes.
---
About backups
Before replacing anything, the script backs up the current files.
If something goes wrong, you can easily restore the previous version.
This is especially useful when testing new builds.
---
About permissions (777)
The script sets permissions to 777 to avoid permission issues during testing.
Important note
777 is NOT recommended for production / live servers
It is acceptable for test, dev, or private setups
For live environments, permissions should be tightened properly
The script favors simplicity over security for development use.
---
Before using it
Make sure:
Your build is already compiled
Servers are stopped before deployment
You run the script as the same user that owns the server files
Paths inside the script match your setup
---
Make the script executable
Run once:
chmod +x deploy_latest.sh
---
How to deploy a build
Run:
./deploy_latest.sh
No arguments needed.
The script will:
Backup old files
Deploy the new build
Apply permissions
Finish in one pass
---
After deployment
Restart your servers normally
If something doesn’t start, check logs first
If needed, restore the backup and investigate
---
Common mistakes
Deploying while servers are still running
Using it directly on a live server without adjusting permissions
Wrong folder paths
---
Final note
This script is meant to:
Speed up deployments
Make updates safer with backups
Keep your workflow clean during development
For production setups, adapt permissions and security rules before using it.
Quick notes :
Made for linux. If you use windows files, you'll need to update the script.
This assumes you have a builds folder with all your compiled builds in it.
