在172.20.26.198LVS服务器上安装ipvsadm
yum install ipvsadm -y
# 配置LVS:
#添加集群服务,调度方式如果不指定默认是wlc
ipvsadm -A -t 172.20.26.200:80
# 添加后端真实服务器工作模式如果不指定默认是DR模式-m为NAT模式如需指定使用-g
ipvsadm -a -t 172.20.26.200:80 -r 172.20.26.218
ipvsadm -a -t 172.20.26.200:80 -r 172.20.26.210
#查看lvs配置
ipvsadm –Ln
### 访问测试
[rootnode2 ~]# curl 172.20.26.200
this is 26.218 page
[rootnode2 ~]# curl 192.168.75.200
this is 26.210 page DR模式二 基于六台服务器部署keepalived lvs DR模式架构(前端带路由)负载均衡的高可用集群
修改网络模式前将所需软件包安装完成
客户端机器网卡模式为桥接模式
路由器上开启数据包的转发
echo 1 /proc/sys/net/ipv4/ip_forward
两台后端服务器
yum install nginx -y 安装nginx
yum install tcpdump -y 安装抓包工具
echo this is RS1.152.129 pages /usr/share/nginx/html/index.html
echo this is RS2.152.128 pages /usr/share/nginx/html/index.html
两台LVS服务器A、B
yum install ipvsadm -y
yum install keepalived -y
echo 1 /proc/sys/net/ipv4/ip_forward
实验环境各台服务器网络配置
1、CIP服务器的网关设置为R外IP172.20.26.6 2、充当路由器的服务器R外的网关设置为物理机的网关地址172.20.26.254 充当路由器的服务器R内的网关设置为仅主机模式的默认网关地址192.168.152.2 3、LVS服务器A的VIP网关设置为路由器R内的IP地址

各台服务器均能相互ping通各台服务器selinux关闭、firewalld关闭开机启动禁用。 LVS服务器A、B上配置ipvsadm
配置LVS:
ipvsadm -A -t 192.168.152.200:80 -s rr
ipvsadm -a -t 192.168.152.200:80 -r 192.168.152.129
