CDH使用MySQL数据库的使用记录

本人记录了下CDH配置Mysql的问题，仅供自己参看

1.mysql的重要配置文件my.cnf(默认在/etc/my.cnf)，记录了datadir 目录等，

2.datadir 目录记录mysql的安装位置，默认情况下是 /var/lib/mysql，需要位于具有足够可用空间的分区上

3.设置MySQL root密码和其他与安全相关的设置。在新的安装中，根密码为空。

按照/usr/bin/mysql_secure_installation文件进行展示修改密码

4.为Cloudera软件创建数据库

mysql -u root -p

Enter password: 123
