yum -y install ipvsadm*
echo 1 > /proc/sys/net/ipv4/ip_forward 路由器功能，ip轉(zhuǎn)發(fā)
ipvsadm -C
ipvsadm -At 192.168.56.101:80 -s rr 輪叫模式
ipvsadm -at 192.168.56.101:80 -r 192.168.0.2 -m
ipvsadm -at 192.168.56.101:80 -r 192.168.0.3 -m
ipvsadm -L -n

2、real-server-1：

ifconfig eth0 192.168.0.2 netmask 255.255.255.0
route add default gw 192.168.0.1

3、real-server-2

代碼如下:

ifconfig eth0 192.168.0.3 netmask 255.255.255.0
route add default gw 192.168.0.1
route -n 查看路由表

 
二、lvs-ipturn
