Enable and start the haproxy service on each server: # chkconfig haproxy on # service haproxy start If you change the HAProxy configuration, reload the haproxy service. Installing HAProxy. Before start installing search, the package availability using # apt search haproxy. Once you see the package available, install it using, # apt install haproxy. Afterwards, you can double check the installed version number with the following command. To enable HAProxy to be started on bootup.

This tutorial will explain how to load balancing two Tomcat instances with HAProxy in openSUSE.

The environment will be simulated with three virtual machines and VirtualBox:

Haproxy
#Server FQDNIP
1haproxy-server.dalanzg.com192.168.56.101HAProxy - Port 80
2tomcat-server1.dalanzg.com192.168.56.102Apache Tomcat - Port 8080
3tomcat-server2.dalanzg.com192.168.56.103Apache Tomcat - Port 8080

Check the following post to configure openSUSE with Internet and statick IP address by using YaST on VirtualBox

Steps

Install HAProxy

Friedland doorbell manual. Install HAProxy in server #1

Check HAProxy works in server #1 from your host machine.

Install Apache Tomcat

Steps for servers #2 and #3:

  • Download apache-tomcat-8.5.34.tar.gz
  • Deploy Apache Tomcat and change permissions
  • Start service
  • Create a static html file

And create a static html file.

Check you can reach the index page from servers #2 and #3:

  • http://192.168.56.102:8080/dalanzg
  • http://192.168.56.103:8080/dalanzg

Load Balancing Across Multiple Backend Servers with HAProxy

The HAProxy configuration will work with the following features:

  • All the Apache request will be balanced from http://192.168.56.101/dalanzg to:
    • http://192.168.56.102:8080/dalanzg
    • http://192.168.56.103:8080/dalanzg
  • The stats will be accessed with:
    • http://192.168.56.101:9000/stats
    • User authentication:
      • User: admin
      • Password: haproxy

Edit haproxy.cfg configuration file.

Restart HAProxy.

Check stats with authentication in http://192.168.56.101:9000

Go several times to http://192.168.56.101/dalanzg

And now, shutdown Tomcat 2 and check that http://192.168.56.101/dalanzg is still working in Tomcat 1.

And tomcat2 is down in stats page.

An openSUSE virtual machine will be configured to have a static IP address and Internet connection on VirtualBox.This scenario is really useful if you want to install a specific application in guest and you need to communicate from your host.Therefore, the virtual machine will have two network adapters:NAT -> Internet connection Host-only-adapter -> Static IP address (192.168.56.200) and FQDN server1.dalanzg.com Steps Settings for VirtualBox Virtual machine network settings Settings for network devices Settings for VirtualBox First, create a Host Network Manager in VirtualBox.

Installing Haproxy On Windows 8.1

HAProxy is a very fast and reliable solution for high availability, load balancing, It supports TCP and HTTP-based applications. Nowadays most of the websites need 99.999% uptime for their site, which is not possible with single server setup. Then we need some high availability environment that can easily manage with single server failure.

This article will help you to install HAProxy on CentOS, RHEL servers and will configure a Layer 4 Load Balancing (Transport Layer). Which will balance load and transfer requests to different-2 servers based on IP address and port numbers.

Step 1 – Install HAProxy

HAProxy package is available under the default yum repository for CentOS, Redhat systems. Use the following yum package manager command to install HAProxy on your system.

Step 2 – Configure HAProxy

Update your HAProxy configuration file /etc/haproxy/haproxy.cfg as per your requirement, You may also use below given configuration file as an example of setup and modify it.

[ Update red mark values as per your network setup ]

Change the ips in configuration file as per your network setup. In HTTP Site Configuration section if any request on ip 192.168.10.10 on port 80, this will be redirected to port 80 of 192.168.10.100 or 192.168.10.101 servers. Similarly in HTTPS Site Configuration if any request on ip 192.168.10.10 on port 443, this will be redirected to port 443 of 192.168.10.100 or 192.168.10.101 servers.

You also need to make a few changes in the configuration file as per your system configuration.

  • nbproc <value> # Number of processing cores in your system.
  • mode <value> # ‘http’ for http site and ‘tcp’ for https site
  • balance <value> # Type of load balancing like ‘source’, ’roundrobin’ etc.

    • Step 3 – Start HAProxy Service

    Start HAProxy service using the following command, also configure it to auto-start on system boot.

    And You have done it.

    Congratulation’s! you have successfully configured HAProxy load balancer. Read next article to enable haproxy stats and setup ACL in HAProxy.
