Cannot connect to MySQL because the Perl DBD::mysql module is not installed or not found.

?Perl DBD::mysql module is not installed? 有和我一樣遇到這個問題嗎？

[root@hive percona-toolkit-2.2.4]# pt-duplicate-key-checker -h 127.0.0.1 -u root -p root

Cannot connect to MySQL because the Perl DBD::mysql module is not installed or not found.? Run 'perl -MDBD::mysql' to see the directories that Perl searches for DBD::mysql.? If DBD::mysql is not installed, try:

? Debian/Ubuntu? apt-get install libdbd-mysql-perl

? RHEL/CentOS? ? yum install perl-DBD-MySQL

? OpenSolaris? ? pgk install pkg:/SUNWapu13dbd-mysql
