Apakah bisa SSL terinstall gratis dan seumur hidup?

Jawabannya bisa, karena sudah ada SSL gratis yang disediakan oleh Provider SSL Lets Encrypt. Caranya gampang, anda perlu install Apache, di Ubuntu Server 20.04 nya dan buat virtual host domain/subdomain anda contohnya disini saya menggunakan subdomain ssl.alvianaufan.my.id.

Buat file .conf untuk setting virtual hostnya:

nano /etc/apache2/conf-enable/vhost.conf

– Lalu masukkan code berikut:

<VirtualHost *:80>
ServerAdmin webmaster@alvianaufan.my.id
DocumentRoot "/var/www/html"
ServerName ssl.alvianaufan.my.id
ServerAlias www.ssl.alvianaufan.my.id
ErrorLog /etc/apache2/error.log
CustomLog /etc/apache2/access.log common
</VirtualHost>

– Save dan exit.

Pastikan untuk subdomain ssl.alvianaufan.my.id dan alias www.ssl.alvianaufan.my.id sudah mengarah ke alamat IP Apache Server nya. Bisa setting melalui panel nameserver domain utamanya ya. Contohnya disini saya menggunakan panel nameserver cloudflare:
Setelah itu install certbot python3 melalui console server.
```
apt install certbot python3-certbot-apache
```

Jalankan generate SSL nya menggunakan command certbot:

certbot --apache -d ssl.alvianaufan.my.id -d www.ssl.alvianaufan.my.id

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/ssl.alvianaufan.my.id/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/ssl.alvianaufan.my.id/privkey.pem
   Your cert will expire on 2022-04-06. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

Jika sudah silahkan cek akses subdomain nya melalui browser.
– SSL sudah berhasil aktif dan pada keterangan periode aktif nya hanya 3 bulan. Dan setelah 3 Bulan maka certbot akan menjalankan generate SSL baru secara otomatis.

Pastikan status certbot.timer nya aktif, agar auto generate ssl nya dapat berjalan dengan sendirinya.

systemctl status certbot.timer

● certbot.timer - Run certbot twice daily
