Nginx 常用配置

• 静态资源

location / {
  root /usr/share/nginx/html;
  index index.html;
}

• 静态资源(单页面应用)

location / {
  root /usr/share/nginx/html;
  index index.html;
  try_files $uri /index.html;
}

• 反代API接口

location /api {
    proxy_pass http://server:port;
    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;
  }

• SSL 配置

  listen 443 ssl;
  http2 on;
  server_name xxx.com;
  root /usr/share/nginx/html/html/xxx;

  access_log /var/log/nginx/xxx.access.log  main;

  ssl_certificate /cert/fullchain.pem;
  ssl_certificate_key /cert/privkey.pem;
  ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
  ssl_ciphers EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
  ssl_prefer_server_ciphers on;
  ssl_session_cache shared:SSL:10m;
  ssl_session_timeout 10m;
  add_header Strict-Transport-Security "max-age=31536000";

• 反代WS

location /ws/api {
    proxy_pass http://server:port;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    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;
  }

• 最大请求/响应等限制

location /upload/ {
    # 对于上传，可以适当增大此值，让小文件直接在内存中处理
    client_body_buffer_size 128k;
    client_max_body_size 200m;
}
