Question

CentOS下的LVS+keepalived+tomcat7的集群，只有当一台tomcat关掉才会去访问另一台tomcat？求大神急救

现在的问题就是，它不会去轮流的访问不同机器上的tomcat服务器，但是高可用没问题，容灾也没问题，就是不会负载均衡。。。。。。。。。。。。。。。求大神解答

配置如下：========
主机：[root@lcg2 keepalived]# vi keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
test@sina.com
}
notification_email_from admin@test.com
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id LVS_MASTER
}

vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 51
priority 90
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.249.100
}
}

virtual_server 192.168.249.100 8080{
delay_loop 6
lb_algo rr
lb_kind DR
nat_mask 255.255.255.0
persistence_timeout 2
protocol TCP

real_server 192.168.249.2 8080 {
weight 1
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
connect_port 8080

}
}

real_server 192.168.249.3 8080 {
weight 1
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
connect_port 8080
}
}
real_server 192.168.249.4 8080 {
weight 3
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
connect_port 8080
}
}
real_server 192.168.249.5 8080 {
weight 3
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
connect_port 8080
}
}
}
