I installed MySQL using mysql-installer-5.5.20.0.msi on Windows 7. From the cmd window, I run \"mysqlshow -u root -p\". It asked for a password, then return
For me, three steps solved this problem on windows 10:
I downloaded MySQL server community edition zip and extracted it in the D drive. After that I went to bin folder and did cmd on that folder. I followed the below steps and all works:
D:\tools\mysql-8.0.17-winx64\bin>mysqld -install
Service successfully installed.
D:\tools\mysql-8.0.17-winx64\bin>mysqld --initialize
D:\tools\mysql-8.0.17-winx64\bin>net start mysql
The MySQL service is starting...
The MySQL service was started successfully.
