nginx proxy server

In recent years, with the continuous development of Internet applications, nginx proxy server plays an increasingly important role in network architecture. As a high-performance HTTP and reverse proxy server, nginx is favored by many enterprises because of its excellent performance in handling static files, load balancing, and acting as a reverse proxy.

The configuration of nginx is flexible and powerful, through a simple configuration can be realized to build a proxy server. The following is a simple example of nginx proxy server configuration:

"`nginx
server {
listen 80.
server_name example.com.

location / {
proxy_pass http://backend_server.
proxy_set_header Host $host.
proxy_set_header X-Real-IP $remote_addr.
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
“`

With the above configuration, nginx can act as a proxy server to forward client requests to the back-end server, and carry the necessary header information during the forwarding process, realizing a simple and efficient proxy function.

nginx proxy server access offshore

In practice, sometimes we need to access resources outside the country through the nginx proxy server, such as foreign API interfaces or foreign websites. In this case, we can set the proxy parameters of nginx to realize the access of foreign resources.

Below is a simple example configuration of nginx proxying offshore resources:

"`nginx
server {
listen 80.
server_name example.com.

location / {
proxy_pass http://overseas_server.
proxy_set_header Host $host.
proxy_set_header X-Real-IP $remote_addr.
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

resolver 8.8.8.8.
}
}
“`

In the above configuration, we specify the offshore DNS servers by setting the resolver parameter, so that nginx can correctly resolve the domain names of offshore resources and realize the access proxy for offshore resources. In this way, the nginx proxy server can easily access the overseas resources and forward them to the client, realizing the need to access the overseas resources.
