Ubuntu系统安装MariaDB数据库的方法

安装mariadb  下载二进制包
shell> groupadd mysql
shell> useradd -r -g mysql mysql
我输入的是
shell> useradd -g mysql mysql
shell> cd /usr/local
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz   
shell> ln -s full-path-to-mysql-VERSION-OS mysql
解压我安装自己的方式解压的

shell> mv mysql-VERSION-OS mysql

shell> cd mysql
shell> chown -R mysql .
