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
