后出现错误
FATAL ERROR: please install the following Perl modules before executing /usr/local/mysql/scripts/mysql_install_db:
Data::Dumper
解决方法
这个是因为缺少autoconf库所以需要安装autoconf库
命令：yum -y install autoconf //此包安装时会安装Data:Dumper模块
安装完autoconf库再次初始化 dumper报错问题消失
# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/mysqldata
