FTP-Based Multi-Server Deployment Automation

Deploying to shared hosting via FTP sounds archaic, but it's the reality for many PHP applications. Here's how I automated multi-server FTP deployment for TrendVidStream , a video platform running on 4 LiteSpeed servers. The Problem Manual FTP deployment to 4 servers is slow, error-prone, and tedious. I needed: Parallel deployment to all servers Automatic exclusion of sensitive files LiteSpeed cache clearing after deploy Post-deploy verification The Solution: ops.sh A bash script wrapping lftp for parallel FTP mirroring. Configuration File # deploy_hosts.conf # CRITICAL: Must have Unix line endings (LF only, NO \r) # format: alias|host|user|pass|remote_path dwv|ftp.dailywatch.video|user1|pass1|/htdocs tvh|ftp.topvideohub.com|user2|pass2|/htdocs tvs|ftp.trendvidstream.com|user3|pass3|/htdocs vvv|ftp.viralvidvault.com|user4|pass4|/htdocs Deploy Script #!/bin/bash # ops.sh - Multi-server deployment automation set -euo pipefail CONFIG_FILE = "deploy_hosts.conf" EXCLUDE_PATTERNS =( "--exclu
