nginx动静分离,怎么做proxy_pass-----upstream

可以将静态资源和动态资源分别放在不同的服务器上，然后使用nginx的proxy_pass模块将请求转发到对应的upstream中。配置文件示例：

upstream dynamic_backend {
server localhost:8080;
}
upstream static_backend {
server localhost:8090;
}
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://dynamic_backend;
}
location /static/ {
proxy_pass http://static_backend;
}
}

在给出的 Nginx 配置中，`mxapi.hckcooler.com` 代理了 `fsapiBackend` 这个服务。可以看到以下配置：

location /fs/ {
    proxy_pass http://fsapiBackend/;
    ...
}
location =/fs/v2/mails/deliver {
    proxy_pass http://fsapiBackend/v2/mails/deliver;
    ...
}

这些配置指定了请求路径以及对应的代理后端，都是指向 `fsapiBackend`。因此，`mxapi.hckcooler.com` 代理的是 `fsapiBackend` 服务。

解释一下server { listen 81; server_name 10.28.8.1; location / { proxy_pass http://10.8.19.9:81/; client_max_body_size 500m; add_header Access-Control-Allow-Methods 'GET,POST,OPTIONS'; add_header Access-Control-Allow-Origin *; add_header backendCode $upstream_status; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header REMOTE-HOST $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $Server_name; proxy_connect_timeout 30s; proxy_read_timeout 60s; proxy_send_timeout 60s; proxy_buffering off; }

这段配置是一个 Nginx 的服务器块，监听 81 端口，并且以 IP 地址 `10.28.8.1` 作为域名。这个服务器块的主要作用是将客户端的请求代理到另一个服务器上，这个服务器的地址是 `http://10.8.19.9:81/`。

当客户端发送请求时，Nginx 会将请求发送到 `http://10.8.19.9:81/` 上，并且将响应返回给客户端。在这个过程中，Nginx 还会对一些 HTTP Header 进行修改，例如将 `Host`、`X-Real-IP`、`X-Forwarded-For` 等 Header 设置为客户端的真实信息，这些信息对于后端服务器来说是很有用的。

此外，这个配置还添加了一些额外的 Header，例如 `Access-Control-Allow-Methods`、`Access-Control-Allow-Origin` 等，这些 Header 可以帮助客户端进行跨域请求。`client_max_body_size` 则是设置了客户端请求的最大体积，`proxy_buffering off` 则是关闭了 Nginx 的缓存功能。
