Perl DBD::mysql module is not installed  有和我一样遇到这个问题吗？

[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
