 原因：系统没有按安装DBI组件。

       DBI(Database Interface)是perl连接数据库的接口。其是perl连接数据库的最优秀方法，他支持包括Orcal,Sybase,mysql,db2等绝大多数的数据库。        解决办法：安装DBI、Data-ShowTable、DBD-mysql ( 假设你已安装完perl和mysql数据库 )。具体如下： 到 下载三个文件DBI-1.601.tar.gz、Data-ShowTable-3.3.tar.gz、DBD-mysql-3.0007_1.tar.gz ，分别处于DBI,DATA,BDB目录下。注意下载的DBI的版本不能太低，如之前作者下载过低版本DBI-1.20不能编译通过。 下载后最好保存在目录：/usr/local/src下，并解压产生各模块的安装文件目录。如下 [root@localhost src]#tar zxvf DBI-1.601.tar.gz [root@localhost src]#tar zxvf Data-ShowTable-3.3.tar.gz [root@localhost src]#tar zxvf DBD-mysql-3.0007_1.tar.gz 安装DBI [root@localhost src]# cd DBI-1.601 [root@localhost DBI-1.601]# perl Makefile.PL [root@localhost DBI-1.601]# make [root@localhost DBI-1.601]# make test [root@localhost DBI-1.601]# make install 安装Data-ShowTable [root@localhost src]# cd Data-ShowTable-3.3 [root@localhost Data-ShowTable-3.3]# perl Makefile.PL  [root@localhost Data-ShowTable-3.3]# make  （注：第一次make出错，再make多几次） [root@localhost Data-ShowTable-3.3]# make install （注：无需make test） 安装DBD-mysql [root@localhost src]# cd DBD-mysql-3.0007_1 [root@localhost DBD-mysql-3.0007_1]# perl Makefile.PL --libs="-L/usr/local/mysql-6.0.9-alhpa/lib/mysql -lmysqlclient -lz -lrt -lcrypt -lnsl -lm"  --cflags=" -I/usr/local/mysql-6.0.9-alpha/include/mysql -g -DUNIV_LINUX" --testuser=root --testsocket=/home/cserken/mysql/tmp/mysql.sock [root@localhost DBD-mysql-3.0007_1]# make [root@localhost DBD-mysql-3.0007_1]# make test [root@localhost DBD-mysql-3.0007_1]# make install 安装完毕 注意：make test之前mysql server要启动，并且要知道server的socket。本文在调试模式下启动mysql server，可获取到socket。 [root@localhost src]# cd /usr/local/mysql-6.0.9-alpha （mysql 安装路径） [root@localhost mysql-6.0.9-alpha]# gdb libexec/mysqld  (gdb) r --user=root The program being debugged has been started already.
