Mysql installation on Linux <CentOS> server, by itself due Centos yum Mysql branch source Mariadb replaced MySQL, so had to choose embodiment rpm or tar.gz package installation,
But in order to later in other LInux such as Ubuntu installation are also proficient in MySQL, it is recommended to use tar.gz, installation guide -http: //blog.csdn.net/qq_32331073/article/details/76252559
