Command line for LB

Help!
1

Can not use command line for load balancing configuration?
I tried to use HAProxy as LB, but I couldn’t find a command line for LB.

There isn’t an actual CLI tool for HAProxy, but it does have a management socket to which you can send commands like described in the management documentation:

thank you for your answer.
I will try to use that management socket.
