Mysql 5.6

Debian 8

Firstly install mysql 5.6 repositor from mysql community:

mkdir /usr/src/mysql
cd /usr/src/mysql
wget https://dev.mysql.com/get/mysql-apt-config_0.3.6-1debian8_all.deb
dpkg -i  mysql-apt-config_0.3.6-1debian8_all.deb

When asked for products (select server -> mysql-5.6 ->Apply)

apt-get update
apt-get install mysql community server

When asked for root password leave it blank for now

mysql_secure_installation

#Remove anonymous users? Yes
#Disallow root login remotely?Yes
#Remove test database and access to it? Yes
#Reload privilege tables now? Yes

You can test that your mysql is running. Don't forget to set in /etc/mysql/my.cnf in [mysqld] section options for best performance as discused in scalling section of manual([[1]]:

innodb_flush_log_at_trx_commit = 2 
innodb_file_format = barracuda
innodb_buffer_pool_size = 8GB

Size for innodb buffer is basicaly half of your available RAM if you have 16G or more but respect your free RAM:(for 2G set 256M, 4G set 512M, 6G set 2G, 8G set 3G) /etc/init.d/mysql restart
