Nginx 反向代理配置
把一個域名代理到本地服務的標準寫法。
範本正文
server {
listen 443 ssl;
server_name app.example.com;
ssl_certificate /etc/nginx/certs/app.crt;
ssl_certificate_key /etc/nginx/certs/app.key;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
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;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 60s;
}
location /api/ {
proxy_pass http://127.0.0.1:8100;
}
}怎麼用
新增子域名或上線新服務時複製修改。
使用要點
- 漏掉 X-Forwarded-Proto，後端會以為用戶訪問的是 http，容易生成錯的跳轉連結。
- 改完先 nginx -t 再 reload，避免配置錯導致整站掛掉。
