How to configure nginx reverse proxy

Reverse proxy is the most commonly used server function in work and is often used to solve cross-domain problems. Let’s briefly introduce how to implement reverse proxy.

First enter the main configuration file of Nginx:

vim /etc/nginx/nginx.conf

(Recommended tutorial:nginx usage tutorial)

Then we go to the server block of the http module location/, add a line to redirect the default URL to the proxy_pass configuration of the largest learning website Bilibili:

Save and exit after changing,nginx -s reloadReload, enter the default URL, and now jump directly to station B, implementing a simple proxy.

In actual use, the request can be forwarded to another server on this machine, or it can be jumped to a service on a different port based on the access path.

For example, we listen to port 9001, and then perform reverse proxy for requests to access different paths:

Forward requests to access http://127.0.0.1:9001/edu to http:/ /127.0.0.1:8080

Forward the request to access http://127.0.0.1:9001/vod to http://127.0.0.1:8081

How to configure this , first open the main configuration file, and then add a server block under the http module:

server { listen 9001; server_name *.sherlocked93.club; location ~ /edu/ { proxy_pass http://127.0.0.1:8080; } location ~ /vod/ { proxy_pass http://127.0.0.1:8081; } }

There are some other instructions for reverse proxy, you can learn about it:

1. proxy_set_header: in Change the request header information from the client before sending it to the backend server.

2. proxy_connect_timeout: Configure the timeout period for Nginx to try to establish a connection with the backend proxy server.

3. proxy_read_timeout: Configure Nginx to wait for the corresponding timeout after issuing a read request to the backend server group.

4. proxy_send_timeout: Configure Nginx to wait for the corresponding timeout after sending a write request to the backend server group.

5. proxy_redirect: used to modify the Location and Refresh in the response header returned by the back-end server.
