When installing mysql and memcached, why is there only a server side and a client side

for example:
both software can be divided into client and server. Is it impossible to install only the server when deploying the server? Why do I have to install a client?

is mainly because mysql has its own communication protocol, and if the development environment needs debugging, it must be necessary
. Of course, if you ask if there is no special cs side that can be accessed, I can tell you that there is couchdb you can take a look at the http/json interface, and the browser can access


of course you can install only one server. The client is just convenient for you to debug on the command line
