NOTE: Normally it is recommended to install MariaDB server instead of classic MySQL server !!
# systemctl stop mariadb # systemctl disable mariadb # yum remove mariadb-server mariadb mariadb-libs ! consider consequences of following: # rm- rf /var/lib/mysql # wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm # rpm -ivh mysql-community-release-el7-5.noarch.rpm # vim /etc/yum.repos.d/mysql-community.repo make sure you have enabled correct repo for the version you want, by default it is 5.6 # yum install mysql-server # systemctl start mysqld # systemctl enable mysqld # mysql_secure_installation
