出现错误：

     FATAL ERROR: please install the following Perl modules before executing /usr/local/mysql/scripts/mysql_install_db:

Data::Dumper   

解决方法 ：安装autoconf库

  命令：yum-y install autoconf   //此包安装时会安装Data:Dumper模块

安装完autoconf库，再运行/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/     ，问题消失！！！
