CentOS 7.2 Installation mariadb detailed process _linux

MARIADB Introduction

MARIADB database management System is a branch of MySQL, mainly by the open source community in the maintenance, the use of GPL licensed license MARIADB is fully compatible with MySQL, including APIs and command line, so that it can easily become a replacement for MySQL. On the storage engine side, use XTRADB (English: xtradb) to replace the MySQL InnoDB. MARIADB, led by MySQL founder Michael Widenius (English: Michael Widenius), had previously sold his company, MySQL AB, to Sun at a price of 1 billion dollars, and since then, as Sun was acquired by Oracle, MySQL's ownership also falls into Oracle's hands. The name of MARIADB is from the name of Michael Widenius's daughter Maria.
