Step 1: Switch to Root User

Open your terminal and execute the following command to become the root user:

Step 2: View debian-sys-maint User and Password

Execute this command to display the Debian System Maintenance (debian-sys-maint) user and its password:

# cat /etc/mysql/debian.cnf
# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host     = localhost
user     = debian-sys-maint
password = **************
socket   = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host     = localhost
user     = debian-sys-maint
password = **************
socket   = /var/run/mysqld/mysqld.sock

Note down the debian-sys-maint user’s password for use in the next step.

Step 3: Connect to the Local MySQL Server

Use the debian-sys-maint credentials to connect to your MySQL server:
