[原创]LVS/NAT模式负载均衡示例

LVS/NAT:

LB:

eth0:
    inet 192.168.57.120/24 brd 192.168.57.255 scope global eth0
    inet 192.168.57.126/24 brd 192.168.57.255 scope global secondary eth0:126
eth1:
    inet 10.10.57.120/24 brd 10.10.57.255 scope global eth1
    inet 10.10.57.2/24 brd 10.10.57.255 scope global secondary eth1:2

lvs命令:

ipvsadm -A -t 192.168.57.126:8080 -s wlc -p 30

ipvsadm -a -t 192.168.57.126:8080 -r 10.10.57.122:8080 -w 10 -m

ipvsadm -a -t 192.168.57.126:8080 -r 10.10.57.123:80 -w 10 -m

ip addr add 192.168.57.126/24 brd 192.168.57.255 dev eth0 label eth0:126

ip addr add 10.10.57.2/24 brd 10.10.57.255 dev eth1 label eth1:2

echo "1" >/proc/sys/net/ipv4/ip_forward         #LVS/NAT模式必须要开启包转发

 

RS:

关闭eth0端口, eth1端口的网关必须配置为10.10.57.2,并确保默认路由为eth1，否则不能返回应答包.
