keepalived 问题

Question

我的keepalived 日志显示我的负载均衡几已经进入master状态

下面是keepalived的配置文件

! Configuration File for keepalived global_defs {     #  notification_email {     #    acassen@firewall.loc     #    failover@firewall.loc     #    sysadmin@firewall.loc     #  }     #  notification_email_from Alexandre.Cassen@firewall.loc     #  smtp_server 192.168.200.1     #  smtp_connect_timeout 30     router_id LVS_DEVEL    } vrrp_instance VI_1 {         state MASTER             interface eth0          virtual_router_id 51       priority 100                 advert_int 5               authentication {              auth_type PASS         auth_pass 1111     }     virtual_ipaddress {             192.168.200.88     } } virtual_server 192.168.200.88 80 {         delay_loop 6                       lb_algo wrr                   lb_kind DR         nat_mask 255.255.255.0               persistence_timeout 0             protocol TCP                          real_server 192.168.200.101 80 {         weight 1                         TCP_CHECK {                             connect_timeout 5                   nb_get_retry 3                    delay_before_retry 3             connect_port 80                 }     }     real_server 192.168.200.100 80 {         weight 1         TCP_CHECK {             connect_timeout 5             nb_get_retry 3             delay_before_retry 3             connect_port 80         }     } }

我单独访问100  和 101 机器都能正常访问 页面  但是通过88 负载均衡机器就访问不到  ， 这几台机器网络都能ping同   起防火墙都关闭了    ， 为什么 负载均衡没正常转发啊？？？？？

Answer 1

Keepalived+LVS或者LVS都是做高可用的，不是做负载均衡的。

你配置了Keepalived，还必须正确配置LVS的DR或者TUN。不然是用不了的。

Answer 6

keepalive不是做高可用的吗，负载均衡是不是还需要一些组件来支持啊，例如apache,或者lvs

Answer 7

是啊，那你的配置下lvs,不要再纠结keepalive的配置了

Answer 8

lvs是linux2.6内核自带了

Answer 9

DR模式需要realserver也绑定vip地址
