搭建NAT模式的HTTP环境
网络拓扑图如下
网络环境
RS1 192.168.198.138
RS2 192.168.198.120
LVS：
DIP 192.168.198.128
vip 172.16.253.105
路由R1：
172.16.253.166
192.168.80.128
Client 192.168.80.129
RS1,RS2的网关指向192.168.198.128，client的网关指向R1
实现NAT模式的轮询rr模式

添加路由转发选项
[root@VS ~]# vim /etc/sysctl.d/99-sysctl.conf
net.ipv4.ip_forward=1
[root@VS ~]# sysctl -p /etc/sysctl.d/99-sysctl.conf \\刷新生效
net.ipv4.ip_forward = 1
[root@VS ~]# route add -net 192.168.80.0/24 gw 172.16.253.166
[root@VS ~]# route -n

配置LVS的调度算法为rr轮询
[root@VS ~]# yum -y install ipvsadm
[root@VS ~]# ipvsadm -A -t 172.16.253.105:80 -s rr \\-t指定TCP协议，-s指定调度算法为轮询
[root@VS ~]# ipvsadm -a -t 172.16.253.105:80 -r 192.168.198.138 -m \\添加192.168.198.138 RS1服务器到LVS调度，-m 为nat类型
[root@VS ~]# ipvsadm -a -t 172.16.253.105:80 -r 192.168.198.120 -m
[root@VS ~]# ipvsadm -Ln \\查看LVS调度信息
