ipvsadm与keepalived整合
1.准备两台虚拟服务器(DR),分别安装ipvsadm和keepalivedyum -y install ipvsadm
yum -y install keepalived
2.配置keepalived.conf
#修改IP为192.168.2.137的DR
vi /etc/keepalived/keepalived.conf
#修改内容如下
! Configuration File for keepalived
global_defs {
notification_email {
root@localhost
}
notification_email_from lvs@localhost
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id LVS_DEVEL
}
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 51
priority 50
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.2.150/24 dev eth0 label eth0:1
}
}
virtual_server 192.168.2.150 8080 {
delay_loop 6
lb_algo wlc
lb_kind DR
nat_mask 255.255.255.0
persistence_timeout 50
protocol TCP
real_server 192.168.2.137 8080 {
weight 1
HTTP_GET {
url {
path /
status_code 200
}
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
}
real_server 192.168.2.138 8080 {
weight 1
HTTP_GET {
url {

status_code 200
}
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
}
}

}
connect_timeout 3

}
}
}
3.准备两台RealServer(RS)
IP为:
192.168.2.137
192.168.2.138
4.分别为RealServer安装httpd服务
yum -y install httpd
5.启动httpd
service httpd start
6.启动keepalived
service keepalived start
#可以查看一个是主,一个是从
ifconfig
7.请求192.168.2.150:8080可以看到访问结果
