nginx load balancing instance analysis

Note on load balancing of nginx. As you can see, since our website is in the early stages of development, nginx only acts as an agent for one back-end server. However, as our website’s reputation has grown and more and more people are visiting, one server cannot handle it. , so we added multiple servers. How do we configure proxies for so many servers? Here we take two servers as an example to demonstrate for everyone. 1. Upstream load balancing module description case: The following sets the load balancing server list. upstreamtest.net{ip_hash;server192.168.10.13:80;server192.168.10.14:80down;server192.1

How to use Nginx to handle Vue's development environment

How to use Nginx to handle Vue's development environment

1. The local test domain name needs to be the same as the online domain name in order to correctly deliver cookies and perform SSO testing. Note: Since the relevant cookies are added to the fourth-level domain name after sso login, the local test domain name and the online interface domain name need to be the same. 2. The plan is to configure the host file so that the online domain name points to localhost: 127.0.0.1product.xxx.xxx.com and configure nginx for corresponding forwarding: server{listen80;listen[::]:80;server_name${product.xxx.xxx. com};location/api{proxy_passhtt

How to solve nginx 502 Bad Gateway error

How to solve nginx 502 Bad Gateway error

This configuration specifies what kind of errors nginx encounters when fetching data from a back-end host. It will go to the next back-end host. What is written in it is all the 502s that will appear. In this case, the default is errortimeout. Error refers to crashes, disconnections, etc. Timeout refers to read blocking timeout, which is easier to understand. I usually write it all: proxy_next_upstreamerrortimeoutinvalid_headerhtt
