However, sometimes we’d like to have root access on our mysql databases via sudo. This is possible when performing the following steps as root:

  1. $ touch /root/.my.cnf
  2. $ chmod 600 /root/.my.cnf
  3. Put the following text into /root/.my.cnf: 
    [client]
password        = <mysql root password>
port            = 3306
host            = localhost
socket          = path/to/your/mysql.sock

When having a .my.cnf file in the home-directory, executing mysql starts the mysql-client under the currently logged-in user and by using the password provided in the ~/.my.cnf file. This also means, that

$ sudo -H mysql

starts the mysql-client under mysql-”root.” The option “-H” is necessary because sudo has to change the home-directory to the system’s root user, i.e., /root/. Otherwise, mysql uses the ~/.my.cnf file of the user executing sudo.
