MySQL download, installation, configuration (version 5.7.19)

My computer is win7 64-bit system, and I will record the problems encountered in the installation of mysql5.7.19 version:

1: Download the compressed package

1. Download MySQL Community Server 5.7.19 from the MySQL official website , this version is a free version.
