[root@localhost mysql]# ./scripts/mysql_install_db  --user=mysql

-bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: No such file or directory

貌似提示注释器错误，没有/usr/bin/perl文件或者档案，解决办法（安装perl跟perl-devel即可）：

执行  yum -y install perl perl-devel

后在初始化数据库即可。

 bin/mysql_install_db
FATAL ERROR: please install the following Perl modules before executing /usr/bin/mysql_install_db:
Data::Dumper

yum install -y perl-Data-Dumper 即可。。
