u Mster keepalived配置

只需要将更改lb_kind TUN，backup机对应修改即可！

[root@localhost ~]# vi /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

notification_email {

88fly@163.com

chenhaibo@myhexin.com

sysadmin@firewall.loc

}

notification_email_from Alexandre.Cassen@firewall.loc

smtp_server smtp.163.com

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 {

192.168.15.253

}

virtual_server 192.168.15.253 80 {

#delay_loop 10

lb_algo wlc

lb_kind TUN

# persistence_timeout 1

protocol TCP

# sorry_server 127.0.0.1 80

real_server 192.168.15.233 80 {

weight 1

TCP_CHECK {

connect_timeout 1

nb_get_retry 3

delay_before_retry 3

connect_port 80

}

real_server 192.168.15.234 80 {

weight 1

TCP_CHECK {

connect_timeout 1

nb_get_retry 3

delay_before_retry 3

connect_port 80

}

注：测试时将keepavlived里配置信息（weight、connect_timeout等）可自行设置。若要查看测试效果，则设置（connect_timeout 1 、weight 1 ，便于查看切换)
