结果

Implemented ten lightweight Bash scripts that automated critical maintenance tasks, freeing team members from repetitive work and preventing the majority of surprise incidents.

工作流

• 1. Create backup-and-prune.sh to tar nightly and prune 30‑day old backups. 2. Create disk-watchdog.sh to alert when disk usage exceeds 80%. 3. Create ssl-expiry-check.sh to warn 14 days before any cert expires. 4. Create log-rotate-and-ship.sh to rotate, compress, and ship logs to cold storage. 5. Create healthcheck-sweep.sh to curl all endpoints and post failures to Slack. 6. Create db-snapshot.sh to perform logical dump and checksum verification. 7. Create user-audit.sh to list active accounts and last login. 8. Create deploy-and-tag.sh to deploy with a git tag and changelog entry. 9. Create uptime-daily-report.sh to email a 6 AM summary of all systems. 10. Create restore-drill.sh to restore the last backup to a scratch directory monthly. 11. Schedule each script via cron with appropriate intervals. 12. Package scripts with comments and deploy in an afternoon.
