Centos7.5系统下安装mysql5.6 初始化默认数据库运行此命令：/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/   --datadir=/data/mysqldata

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
