通过Virtual IP无法访问到我的MySQL服务器，怎么回事，可以ping通的

load balancer Virtual IP　192.168.100.59

●Load balancer Machine 1
　IP Address:192.168.100.57(MySQL Cluster管理Machine)
　Hostname:loadb1
　Domain name:loadb1.localdomain.com

l●Load balancer Machine 2
　IP Address:192.168.100.58
　Hostname:loadb2
　Domain name:loadb2.localdomain.com

●SQL NODE/NDB NODE(Data NODE) 1

●SQL NODE/NDB NODE(Data NODE) 2
　IP Address:192.168.100.56

通过Virtual IP　192.168.100.59无法访问到192.168.100.55/192.168.100.56任意一个服务器。

heartbeat和ldirectord配置如下：
/etc/ha.d/ha.cf
logfacility local0
bcast eth0
mcast eth0 225.0.0.1 694 1 0
auto_failback off
node loadb1
node loadb2
respawn hacluster /usr/lib/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster

/etc/ha.d/haresources
loadb1 \
IPaddr::192.168.100.59/24/eth0/192.168.100.255 \
ldirectord::ldirectord.cf \
LVSSyncDaemonSwap::master

/etc/ha.d/authkeys
auth 3

/etc/ha.d/ldirectord.cf
# Global Directives

virtual = 192.168.100.59:3306
service = mysql
real = 192.168.100.55:3306 gate
real = 192.168.100.56:3306 gate
checktype = negotiate
login = "ldirector"
passwd = "ldirectorpassword"
database = "ldirectordb"
request = "SELECT * FROM connectioncheck"
scheduler = wrr

在192.168.100.57/192.168.100.58上：
/etc/init.d/ldirectord stop
/etc/init.d/heartbeat start
一切正常，没有发生错误。

从相同网络（192.168.100.x）中的其它服务器用虚拟IP地址192.168.100.59
来访问MySQL数据库: mysql -h 192.168.100.59 -u ldirector -p 失败！！！！

SmallLinux000:/usr/src# mysql -u ldirector -p -h 192.168.100.59
Enter password:
