From entry to proficiency
Nginx is something that cannot be bypassed in the development process. It is mainly used as a reverse proxy. If we have multiple servers, nginx can play an intermediate coordination role. The front end can freely access the resources of each server through configuration. To proxy—a proxy server, it is common in daily development to allow the front-end to complete cross-domain and successfully access the back-end interface. In fact, it is to forward the original backend request after the local server request, and the forwarded request is a request that has completed the proxy and can normally obtain the returned information
Go to the official website to download and install the nginx package of the windows version- nginx official website
Install to the root directory of the D drive, use the cmd command line to enter nginx.exe in the relevant path and press Enter to start, and enter http://localhost:80 in the browser to see the welcome page of nginx.
load balancing
That is, when we have multiple servers, we can specify the weight value of each server, so that the user's first and second visits are the first server, and the third visit is the second, reducing server pressure and handling high concurrency problem, make more reasonable use of the server.
Through some other configurations, it is also possible to directly access the second server after the first server fails to prevent the occurrence of 'hanging'
We need to search for some nginx commands to test whether it works or not
From starting ./nginx to configuring new content or setting a proxy in the config file, using the reload command to restart after modifying the port number, etc. There are many instructions, you can remember a few basic ones first, and then slowly learn to remember
How to see what services a website uses
Most of the servers that view the interface response headers are nginx or nginx-based proxies
What are the codes written in the nginx.conf file ——server
For proxy configuration, write some jump addresses for call success and failure, write some domain names and ports you want to proxy, and achieve the effect we want
There are indeed a lot of pitfalls, and if you don’t pay attention, you will report an error. I have encountered any parsing resource errors or redirect errors.
as the picture shows
picture:
This place -location is to specify the address of the page resource to be parsed, / is matched with / on the path, and it will automatically jump to this address
It's really simple, it's too simple
