heartbeat+lvs+ldirectord+mysql集群

ldirectord无法检测到mysql服务的，mysql启动了ipvsadm -L查看显示所有mysql权重都为0，ldirectord也没启动，已安装了DBI和DBD::mysql,两台机器的出错不一样，启动ldirectord提示出错：DBD driver has not implemented the AutoCommit attribute at /usr/local/lib/perl/5.10.1/DBI.pm line 717. 另一台错误为：
/usr/bin/perl: symbol lookup error: /usr/local/lib/perl/5.10.1/auto/DBD/mysql/mysql.so: undefined symbol: mysql_init？？
