2. Configure the network environment, set static IP, and be able to access the Internet

3. Check if ipvsadm is installed, if not install ipvsadm rpm-ql ipvsadm first

4. install ipvsadm rpm-y install ipvsadm

5. Set Virtual IPifconfig eth0:1 192.168.2.150/24

6. Install multiple Linux servers as RealServers, which can be apache or tomcat. The experimental environment is two RealServers. The static IPs are: 192.168.2.137 192.168.2.138

7. To modify the packet source IP settings, you need to set the kernel parameter echo "1" >/proc/sys/net/ipv4/conf/eth0/arp_ignoreecho "1" >/proc/sys/net/ipv4/conf/all/arp_ignoreecho "2" >/proc/sys/net/ipv4/conf/all/arp_announceecho "2" >/proc/sys/net/ipv4/conf/eth0/arp_announce

8. Set the alias IP of the NIC on the RealServer of the two machines: 192.168.2.150 ifconfig lo:1 192.168.2.150 netmask 255.255.255.255 broadcast 192.168.2.150

9. Add a route setting on the virtual server (DR): route add -host 192.168.2.150 dev eth0:1

10. Add route add -host 192.168.2.150 dev lo:1 on both machines RealServer

11. Install httpdyum -y install httpd#httpdservice httpd start/stop/restart on both RealServers

12. Check whether the web service installation on both machines is successful and can access 192.168.2.137192.168.2.138

13. Using ipvsadm Administration on Virtual Server (DR) Add Cluster Services #Create Cluster Services ipvsadm -Cipvsadm -A -t 192.168.2.150:80 -s wlcipvsadm -a -t 192.168.2.150:80 -r 192.168.2.138-g -w 1ipvsadm -a -t 192.168.2.150:80 -r 192.168.2.137-g -w 1#View ipvsadm -Lnipvsadm -L

14. To check our configuration, visit 192.168.2.150, if you can see the content on both RealServers it means success
