2-lvs的NAT模式集群

1.前期配置

主机名	ip地址
lvs1	eno16777736:192.168.162.22 eno33554976:10.27.136.143
web1	eno16777736:192.168.162.26
web2	eno16777736:192.168.162.25

web1:

1. 关闭防火墙

 systemctl stop firewalld.service

2.设置SElinux

 setenforce 0

3.添加lvs1的ip地址为网关

 route add default gw 192.168.162.22  dev eno16777736

4.下载apache服务

 yum install httpd  -y 

5.设置index.html信息

 echo "web2" > /var/ww/html/index.html

6.设置开机自启动

 systemctl enable httpd 

7.重启apache

 systemctl restart httpd  \\重启apache

web2:

1. 关闭防火墙

 systemctl stop firewalld.service

2.设置SElinux

 setenforce 0

3.添加lvs1的ip地址为网关

 route add default gw 192.168.162.22  dev eno16777736

4.下载apache服务

 yum install httpd  -y 

5.设置index.html信息

 echo "web2" > /var/ww/html/index.html

6.设置开机自启动

 systemctl enable httpd 

7.重启apache

 systemctl restart httpd  \\重启apache

lvs1:

1. 关闭防火墙

 systemctl stop firewalld.service

2.设置SElinux

 setenforce 0

3.设置路由转发

echo 1 > /proc/sys/net/ipv4/ip_forward
echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf

4.安装ipvsadm

yum install -y ipvsadm

5.添加虚拟服务器，设置协议和算法

ipvsadm -A -t 10.27.136.143 -s wrr

6.添加真实服务器，设置权重和模式

ipvsadm -a -t 10.27.136.143:80 -r 192.168.162.26 -w 1 -m
ipvsadm -a -t 10.27.136.143:80 -r 192.168.162.25 -w 1 -m

7.查看规则并且保存

ipvsadm -Ln
ipvsadm-save -n > /etc/sysconfig/ipvsadm

8.测试

curl 10.27.136.143
