LVS的DR模式的配置

3台虚拟机↓
DIP: 10.0.0.31
RIP: 10.0.0.32
RIP: 10.0.0.33
VIP: 10.0.0.99

LVS:

DIP: 10.0.0.31
VIP: 10.0.0.99

#配置VIP，增加eth0:0网卡
    cd /etc/sysconfig/network-scripts/
    cp ifcfg-eth0 ifcfg-eth0:0

#配置内容如下:
    vim ifcfg-eth0:0
    DEVICE=eth0:0
    ONBOOT=yes
    BOOTPROTO=static
    IPADDR=10.0.0.99
    NETMASK=255.255.255.252

#重启网卡
	service network  restart

web1和web2:

RIP: 10.0.0.32
RIP: 10.0.0.33
VIP: 10.0.0.99

#添加VIP，增加lo:0
    cd /etc/sysconfig/network-scripts/
    cp ifcfg-lo ifcfg-lo:0

vim ifcfg-lo:0	
#内容如下：
    DEVICE=lo:0
    IPADDR=10.0.0.99
    NETMASK=255.255.255.252
    ONBOOT=yes

#重启网卡
	service network  restart

#安装Apache，并创建页面
	yum -y install httpd
#启动httpd
	service httpd start

#创建测试页面
    vim /var/www/html/index.html
    内容自己定义

#关闭防火墙
    service iptables stop
    setenforce 0

web1和wed2同时都操作:

#修改arp通告和响应级别
    echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
    echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
    echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
    echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
    route add 10.0.0.99 dev lo

LVS: 增加虚拟服务器

#安装ipvsadm
    yum -y install ipvsadm
    ipvsadm -A -t 10.0.0.99:80 -s rr
    ipvsadm -a -t 10.0.0.99:80 -r 10.0.0.32:80 -g
    ipvsadm -a -t 10.0.0.99:80 -r 10.0.0.33:80 -g
    ipvsadm -Ln
    service ipvsadm save
