How to install a MySQL Server on Ubuntu 16.04 (Xenial)

Steps to go

All commands needs to run as user root or via sudo.

apt-get update
apt-get install mysql-server

Enter a strong password, for the MySQL root user:

Test the MySQL Server

If the installation is completed, you should be able to login to the MySQL server with the command mysql -p.

Reduce IO made by MySQL

service mysql stop
echo "innodb_log_file_size    = 512M" >> /etc/mysql/mysql.conf.d/mysqld.cnf
rm /var/lib/mysql/ib_logfile0
rm /var/lib/mysql/ib_logfile1
service mysql start

Shame on me! I forgot my root password

Cool down. You can use the debian-sys-maint to reset your root password.

mysql --defaults-extra-file=/etc/mysql/debian.cnf
