2. Architecture
- Source Code: GitHub

- CI/CD Tool: Jenkins

- Framework: Yii

- Deployment Path: /var/www/html/oxypc

- Backup Path: /opt/Oxypc_pipeline_code_backup

3. Workflow
Developer pushes code → GitHub → Webhook → Jenkins → Deployment

4. Jenkins Job Configuration

 Job Type: Freestyle
 Source: GitHub repository
 Credentials: GitHub token
 Trigger: GitHub webhook
 Build Step: Execute shell script

4. Deployment Script
Script present in Jenkins Web UI

Dashboard>oxypc>Configuration inside build steps

TARGET_DIR="/var/www/html/oxypc"
WORKSPACE_DIR="/var/lib/jenkins/workspace/oxypc"

mkdir -p $TARGET_DIR
# Ensure permissions before deployment
sudo chown -R jenkins:www-data $TARGET_DIR
sudo chmod -R 775 $TARGET_DIR

# Deploy code
cp -r $WORKSPACE_DIR/ $TARGET_DIR/

# Fix permissions after deployment sudo chown -R jenkins:www-data
$TARGET_DIR sudo chmod -R 775 $TARGET_DIR

5. Backup Script
Script present in /opt/Oxypc_pipeline_code_backup.sh
#!/bin/bash

TARGET_DIR="/var/www/html/oxypc"
BACKUP_DIR="/opt/Oxypc_pipeline_code_backup"

TIMESTAMP=$(date +%Y-%m-%d_%H-%M-%S)

sudo mkdir -p $BACKUP_DIR

if [ -d "$TARGET_DIR" ]; then
sudo cp -r $TARGET_DIR $BACKUP_DIR/oxypc_backup_$TIMESTAMP
fi

6. Retention Policy

Only last 5 backups are retained.

Retention Script
KEEP=5

cd /opt/Oxypc_pipeline_code_backup

ls -1dt oxypc_backup_* | tail -n +$((KEEP+1)) | while read backup
do
sudo rm -rf "$backup"
done

Sudo Configuration

To allow Jenkins to execute privileged commands:

sudo visudo

Add:

jenkins ALL=(ALL) NOPASSWD: ALL
