Construct
1. Turn off all firewalls and security mechanisms
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# iptables -F
[root@localhost ~]# setenforce 0
Second, the debugger machine installs two network cards, requiring IPs of different network segments
As shown above
Third, the debugger machine opens the routing forwarding function
[root@localhost ~]# vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
Open: sysctl -p
Fourth, configure load distribution (debugger machine)
ipvsadm -A -t IP of the second network card: 80 -s rr
ipvsadm -a -t ip of the second network card: 80 -r web node machine ip: 80 -m -w 1
...................
Query the above configuration
ipvsadm -Ln
Five, web node service configuration
Modify the network card configuration and point the gateway to the IP of the debugger machine
Sixth, close the service occupying port 80 and install httpd
yum -y install httpd
systemctl start httpd
Seven, add the test file page
echo "server1" > /var/www/html/index.html
Eight, open the browser input
http://debugger machine ip
Nine, query the load distribution status
ipvsadm -Lnc
