server {
    listen 80;
    server_name service1.example.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

server {
    listen 80;
    server_name service2.example.com;

    location / {
        proxy_pass http://localhost:4000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

    location /service1 {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /service2 {
        proxy_pass http://localhost:4000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

# 1、安装Certbot，Certbot是一个自动化工具，可以帮助你获取和安装SSL证书
# 对于Ubuntu/Debian
sudo apt update
sudo apt install certbot python3-certbot-nginx

# 对于CentOS/RHEL
sudo yum install epel-release
sudo yum install certbot python3-certbot-nginx

# 2. 获取SSL证书，使用Certbot为每个子域名获取SSL证书：
sudo certbot --nginx -d service1.example.com -d service2.example.com

    return 301 https://$host$request_uri;

server {
    listen 443 ssl;
    server_name service1.example.com;

    ssl_certificate /etc/letsencrypt/live/service1.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/service1.example.com/privkey.pem;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

server {
    listen 80;
    server_name service2.example.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name service2.example.com;

    ssl_certificate /etc/letsencrypt/live/service2.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/service2.example.com/privkey.pem;

    location / {
        proxy_pass http://localhost:4000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

自动续费

Let's Encrypt的证书有效期为90天。Certbot会自动设置一个cron任务来续期证书。你可以手动测试续期
sudo certbot renew --dry-run
#linux #nginx #ssl
