2、故障解决
###查看当前系统的dbi与dbd包，，如下表明2个包都已安装
# rpm -qa|grep -i dbi
perl-DBI-1.52-2.el5
# rpm -qa|grep -i dbd
perl-DBD-Pg-1.49-4.el5_8
perl-DBD-MySQL-3.0007-2.el5
###我们首先卸载这2个rpm包
# rpm -e --nodeps perl-DBI-1.52-2.el5
# rpm -e --nodeps perl-DBD-MySQL-3.0007-2.el5
###下面使用yum方式分别安装这2个包
# yum install perl-DBI
