How to do reverse proxy in nginx

How does nginx do a reverse proxy?

The network structure is as shown above.

Maybe you only have one public IP address. But you have a website on your intranet If you need to map to the external network and do not want to add other non-80 ports, you can directly use nginx as a reverse proxy.

First, configure the nginx.conf file.

http { include mime.types; default_type application/octet-stream; client_max_body_size 8m; ################################################################################ include /usr/local/u-mail/config/nginx/reverse-proxy.conf; ################################################################################ #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; upload_progress proxied 1m; ############################################################################### gzip on; #client_max_body_size 50m; client_body_buffer_size 256k; client_header_timeout 3m; client_body_timeout 3m; send_timeout 3m; proxy_connect_timeout 300s; proxy_read_timeout 300s; proxy_buffer_size 64k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_ignore_client_abort on; ############################################################################### include vhost/*.conf; }

The above configuration file refers to the /usr/local/u-mail/config/nginx/reverse-proxy.conf;

configuration file. You can use relative paths for this filling, or The absolute path can be filled in. For the sake of demonstration, the absolute path will be filled in directly.

Then look at the referenced configuration file information.

As above. Then restart the nginx service directly. Check whether it is normal and whether there is any error. If there is no error message, it is OK. If you have multiple websites, you can set multiple server sections in reverse-proxy.conf. .One website and one section. Separate them. It will be convenient to check next time.
