nginx goes global http_proxy proxy

Today I come to share with you about nginx go global http_proxy proxy, I hope to help friends in need. As an operations engineer, I am well aware of the problems encountered in the actual work, so I will provide you with a detailed introduction to the configuration and use of nginx go global http_proxy proxy.

What is http_proxy proxy?

http_proxy代理，顾名思义，就是通过代理服务器来转发http请求和响应的代理。它可以帮助我们实现一些特定的需求，比如代理ip访问速度、访问外网等。

Configure nginx to walk the global http_proxy proxy

First, we need to add the following to the nginx configuration file:

```nginx
http {
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server {
listen 80; }
location / {
proxy_pass http://backend; proxy_http_version 1.1; proxy_http_version 1.1
proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_sets_header
proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; proxy_set_upgrade
proxy_set_header Connection $connection_upgrade; proxy_set_header Host $http_upgrade
proxy_set_header Host $host.
proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Real-IP $remote_addr
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header
proxy_set_header X-Forwarded-Proto $scheme;
}
}
upstream backend {
server backend1.example.com; }
server backend2.example.com; }
}
}
```

In the configuration above, we

An http proxy server is defined and two backend servers are defined through the upstream module. In the location block, we used proxy_pass to set the address of the proxy. In addition, we set some http headers so that the backend servers can get the client's information correctly.

Using the global http_proxy proxy

After the configuration is done, we can use the global http_proxy proxy. For example, we can set the proxy server address in the browser to be the address and port number of the nginx server, so that all http requests will be forwarded through nginx.

export http_proxy=http://nginx-server:80

With the above command, we can set the http_proxy variable to the address and port number of the nginx server, thus implementing a global http proxy.

wrap-up

通过以上的配置和使用方法，我们可以实现nginx走全局http_proxy代理。这样可以帮助我们实现一些特定的需求，比如代理ip访问速度、访问外网等。希望本文对大家有所帮助，如果有什么疑问或者建议，欢迎留言讨论。
