Cara Mengamankan Nginx dengan Letsencrypt di Rocky Linux/Centos 8

Ini dikembangkan oleh Internet Security Research Group (ISRG) dan dipercaya oleh semua browser utama. Ini digunakan untuk mengotomatiskan proses pembuatan sertifikat, validasi, penandatanganan, implementasi, dan pembaruan sertifikat untuk situs web yang aman.

Sertifikat hanya berlaku selama 90 hari, jadi Anda perlu memperbaruinya secara manual atau atau menyiapkan sistem perpanjangan otomatis,

Let's encrypt mendukung penerbitan sertifikasi otomatis untuk Apache, Nginx, Plex, dan HAproxy. Kami akan membahas nginx dalam panduan ini.

Memasang Certbot Let's Encrypt Client

Masuk ke server menggunakan ssh [email protected] -p port :

ssh [email protected]

Perbarui semua paket Anda ke versi terbaru yang tersedia.

sudo dnf update -y

Instal Nginx

sudo dnf install -y nginx

Mulai dan aktifkan nginx

systemctl start nginx
systemctl enable nginx

Untuk ini mari buat konfigurasi nginx:
Konfigurasi Nginx yang diperbarui:

server {
    listen 80;
    server_tokens off;
    client_max_body_size 10M;
    server_name site1.citizix.com;

    access_log /var/log/nginx/site1.citizix.com/access.log;
    error_log /var/log/nginx/site1.citizix.com/error.log;
    ignore_invalid_headers off;

    ## Deny illegal Host headers
    if ($host !~* ^(site1.citizix.com)$ ) {
        return 444;
    }

    root /var/www/site1.citizix.com;

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header   Host $host;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Host $server_name;
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   X-Scheme $scheme;
        proxy_connect_timeout 60s;
        proxy_send_timeout 60s;
        proxy_read_timeout 60s;
    }

}

Instal Klien Certbot

Certbot adalah alat baris perintah yang digunakan untuk menyederhanakan proses untuk mendapatkan dan memperbarui sertifikat SSL Let's Encrypt untuk situs web Anda.

sudo systemctl stop nginx

sudo certbot --nginx --non-interactive --agree-tos --email [email protected] -d site1.citizix.com
