Questions about setting up multiple servers on one website

纯真萨满

Due to the needs of the development of the website, I want to rent two servers for one website, but the related technology is not very well understood. Here, I want to ask how to realize the database sharing data between the two servers, so that the occurrence of When the failure fails, another server assumes the operation of the entire website and keeps the database running without losing data?
Experts with relevant experience, please give a detailed plan and tips, thank you!

If the two servers are in the same computer room, you can set up a main server and a backup server to synchronize the data.

Data security is a very complicated application
It must be considered in terms of hardware and software. Of course, the cost factor is also very important.
There must be redundancy on the hardware, optimization of the software, and convenient backup and data synchronization mechanism.
Of course, you can only do as many things as you have.

The two servers are not in the same computer room. I just want to realize the functions of the Southern site (Southern server), Northern site (Northern server), and Hong Kong site (Hong Kong server) similar to some large websites. How to achieve it?
