Ubuntu OS xen虚拟机上测试LVS和Keepalived负载均衡
Ubuntu OS xen虚拟机上测试lvs和keepalived负载均衡
网络拓扑：
虚拟机管理器和xen虚拟机实例：
step1: 安装LVS和keepalived:在director服务器上，分别安装LVS和keepalived软件，使用命令：
$sudo apt-get install ipvsadm
装keepalived，使用命令：
$sudo apt-get installkeepalived
step2：配置keepalived：安装装完之后，在/etc/keepalived目录下建立keepalived.conf文件，写入配置文件如下：
# Global Configuration
global_defs {
lvs_id director1
}
# VRRP Configuration
vrrp_instance LVS {
state MASTER
interface eth0
virtual_router_id 51
priority 150
advert_int 1
authentication {
auth_type PASS
auth_pass 123456
}
virtual_ipaddress {
192.168.122.38
}
# Virtual ServerConfiguration - for WWW service
virtual_server 192.168.122.3880 {
delay_loop 1
lb_algo rr

persistence_timeout 60
protocol TCP
# Real Server 1 configuration
real_server 192.168.122.36 80{

nb_get_retry 3
delay_before_retry 3
}
real_server 192.168.122.37 80{

}
}
}
