浏览数：29 / 时间：2015年06月12日

    安装好了mysql监控神器innotop，正得意，innotoop不可用，其错误提示为install_driver(mysql) failed: Can‘t load ‘/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/mysql/mysql.so‘ for module DBD::mysql: libmysqlclient.so.15: cannot open shared object file:...经查原有又是DBD惹的祸，这个问题已经发生过好几次了。

1、故障现象
[root@dbsrv1 ~]# cat /etc/issue

3、关于perl-DBD-MySQL
DBD::mysql is the Perl5 Database Interface driver for the MySQL database. In other words: DBD::mysql is an interface between the Perl programming language and the MySQL programming API that comes with the MySQL relational database management system. Most functions provided by this programming API are supported. Some rarely used functions are missing, mainly because no-one ever requested them. :-)
