Industrial SSL & CDN Deployment
Full-Stack Security: Let’s Encrypt + Cloudflare Strict Architecture
Server-Side SSL Generation (Certbot)
Sabse pehle server par Certbot install karke certificate generate karein:
sudo certbot –nginx -d sumitdevops.com -d www.sumitdevops.com
Yeh command aapke Nginx config file mein ssl_certificate ki lines apne aap add kar degi.
Cloudflare DNS & Proxy Hijacking
- Cloudflare Dashboard mein A Record add karein.
- Proxy status hamesha Proxied (Orange Cloud) rakhein.
- GoDaddy Nameservers ko Cloudflare ke Nameservers se replace karein.
Strict SSL Mode Configuration
Ab Cloudflare dashboard mein SSL/TLS -> Overview par jayein:
Isse kya hoga? Cloudflare check karega ki aapke server par Let’s Encrypt ka valid certificate hai ya nahi. Agar hai, tabhi connection allow karega.
🛠️ Industrial Troubleshooting (15 Real Cases)
Case 1: Redirect Loop (301)
Problem: Website baar-baar redirect ho rahi hai.
Fix: Server par HTTP->HTTPS redirect hai aur Cloudflare ‘Flexible’ mode par hai. Dono jagah HTTPS force karein ya mode ‘Full’ karein.
Case 2: 522 Origin Connection Timeout
Problem: Cloudflare aapke server tak nahi pahunch paa raha.
Fix: Check karein server ki Firewall (UFW/Security Group) Port 443 allow kar rahi hai ya nahi.
Case 3: Missing Intermediate Cert
Problem: Android phones par SSL error aa raha hai.
Fix: Nginx mein `fullchain.pem` use karein, sirf `cert.pem` nahi.
Case 4: Mixed Content Warning
Problem: Green lock nahi aa raha.
Fix: Cloudflare dashboard -> Edge Certificates -> Automatic HTTPS Rewrites ON karein.
