MariaDB homebrew install errors

Question

I have just installed MariaDB via homebrew on my Mac. At the end of the installation I got the following error:

Warning: The post-install step did not comple         


        

Answer 1

None of the solution here helped, I had to do this:

The post-install step did not complete successfully MySQL Mac OS Sierra

in short,

• I made a backup of the folder /usr/local/var/mysql , then removed it
• removed Mariadb brew remove mariadb
• reinstalled Mariadb brew install mariadb
• run brew services start mariadb

After that I could access with mysql -u root
