LAMP Stack Optimizer

A comprehensive tool for optimizing and managing LAMP (Linux, Apache/Nginx, MySQL, PHP) stack configurations.

Features

• Automated installation and configuration of LAMP stack
• Component-specific optimization (Nginx, PHP-FPM, MySQL)
• Performance monitoring and analysis
• Configuration backup and rollback
• Cross-platform support (Debian/Ubuntu, RHEL/CentOS)

Installation

Prerequisites

• Bash shell
• Python 3 (for dashboard)
• jq (for JSON processing)
• yq (for YAML processing, optional)
• Root or sudo privileges

Installation Steps

1. Download the script from the Lambda Softworks Customer Portal:

   • Log in to your Lambda Softworks Customer Portal account
   • Navigate to the Files section
   • Download the lamp-optimizer.sh script

2. Make the script executable:

chmod +x lamp-optimizer.sh

3. Install dependencies:

For Debian/Ubuntu:

sudo apt-get update
sudo apt-get install -y python3 jq sysstat

For RHEL/CentOS:

sudo yum install -y python3 jq sysstat

Usage

Basic Commands

1. Install LAMP stack:

sudo ./lamp-optimizer.sh --install-stack

2. Optimize specific components:

sudo ./lamp-optimizer.sh --optimize nginx,php,mysql

3. Analyze performance:

sudo ./lamp-optimizer.sh --analyze-performance

Advanced Options

• --auto-optimize: Automatic optimization based on system analysis
• --backup: Create configuration backup before changes
• --test: Test configuration before applying
• --rollback: Revert to previous configuration

Troubleshooting

Common Issues

1. Permission Errors

   • Ensure the script is run with sudo
   • Check directory permissions
   • Verify user has necessary privileges

2. Service Issues

   • Verify service names in configuration
   • Check systemd service status
   • Review service logs

3. Report Generation Issues

   • Check log directory permissions
   • Verify HTML template access
   • Check disk space

Debug Mode

To enable debug logging:

sudo DEBUG=1 ./lamp-optimizer.sh [OPTIONS]
