How to install Gearman in Homestead on Ubuntu 18?

Question

ubuntu

I decided to improve my level and learn vagrant + homestead for later use on it Laravel
Everything turned out to be installed (the machine on VirtualBox) according to the instructions from the Laravel website .
And now I need a Gearman server.
Maybe I'm not careful or something, but I can't install it, I can't figure out where to enter commands to install the package. Tell me, in which console to enter commands?
If I'm not mistaken, do you need to enter commands already in the console of the Ubuntu virtual machine? But what if I don't know how to authenticate there? Where can I get my username and password?
