Homebrew installation and basic operation commands

Homebrew installation

Today I plan to install MySQL on MAC, because I don't want to install it by downloading the installation package, I want to install it through the command line, and I found the package management artifact (maybe the reason for my ignorance), that is "HomeBrew".

Through understanding, it is found that Homebrew is a missing package management tool under the macOS platform , with many useful functions such as installation, uninstallation, update, viewing, and searching. How simple is it? Package management can be achieved with just one instruction, without you having to care about various dependencies and file paths, which is very convenient and fast. Homebrew will install all these tools to the /usr/local/Cellardirectory and /usr/local/bincreate a symbolic link.
