Centos6.5 安装 MariaDB-10.0.20-linux-x86_64.tar.gz

下载mariadb ：https://downloads.mariadb.org/ 我选择mariadb-10.0.20-linux-x86_64.tar.gz这个版本

复制安装文件 /opt 目录下 并解压到当前目录 tar -zxf mariadb-10.0.20-linux-x86_64.tar.gz

把解压的文件名改为mariadb

groupadd mysql

useradd -g mysql mysql

cd /opt/mariadb

chown -R mysql:mysql /opt/mariadb/data

把mariadb/support-files下的my-medium.cnf复制到mariadb目录下，并改为my.cnf

cp support-files/mysql.server /etc/rc.d/init.d/mysqld

chmod +x /etc/rc.d/init.d/mysqld

cp support-files/my-large.cnf /etc/my.cnf
