使用yum安装了 perl perl-devel相关包（注意：此处安装MySQL时，没有输出安装相关Detail的信息，是因为Perl相关模组没有安装的缘故，此处还漏掉了安装perl-Data-Dumper）
[root@azrlnx06 jirasetup]# yum install -y perl perl-devel
安装完Perl相关组件后，重新安装MySQL，如下所示，安装成功，但是没有输出安装相关Detail的信息（因为没有安装perl-Data-Dumper），启动MySQL报错

找到MySQL的错误日志，然后检查/var/lib/mysql/azrlnx06.err错误日志，发现如下错误信息：
