Let’s first change the header so that you can also recognize the IP address of the requesting client on the web server. Instead, the internal IP address of the HAProxy can be seen in both cases. If you look at the output exactly, then you will find that no place your IP address appears. If you now call the info.php via port 80 or 81, you will see a few more information about your webserver and about the connection setup. Just put a new file after ‘/ var / Write to the file: To get to a few of the headers on the web server, I have PHP installed directly.

This is because the TCP session is not closed immediately and you have the opportunity to send another request to the already opened TCP session. Only when there are more than five seconds between two requests is your TCP session redistributed and possibly landed on another web server. Although configured as a balancing mode roundrobin, you stick to one of the webserver for about five seconds. What do you see?Įxtend the interval of the queries until you switch again between the individual web servers. You should always change between web1 and web2.Ĭhange the port to 81 and ask the test.txt again in short term. Now, use your public IP address and port 80 to retrieve the test.txt file several times at short intervals. Create a text file on your webserver in the / var / and write the hostname. This means your requests are also distributed over port 81 between web1 and web2. Port 81 is configured without a sticky session. your requests are distributed between the web servers.įor Port 81 (Layer-4 Loadbalancing) it behaves similarly. Port 80 does not have a sticky session configured, i.e. Port 80 has a so-called Layer-7 Loadbalancing (to recognize at the mode http). All requests that HAProxy receives on port 80 are forwarded to the backend servers, which are grouped under the group “port_80”. Let’s take a quick look at the configuration of why this is so. Again, the web server should present its standard page. If this works, try the same with port 81. You should get a default web page from Apache2. Just call the IP address of your HAProxy server in your web browser. You can easily test whether your HAProxy works. If everything has worked, then your installation should look as follows. You can check the configuration file and the command to restart the network interfaces from your HAProxy server. For web1 I have 10.0.0.2 and for web2 I have taken 10.0.0.3.
#Install haproxy on kali linux upgrade
Now edit the file ‘/ etc / network / interfaces’ on your servers and upgrade the network interface eth1 with an internal IP.
#Install haproxy on kali linux install
$ apt-get -y install vim wget libapache2-mod-php5 I would like to use PHP5 later in order to output a few data on the web server. All possible dependencies should be solved, at the end you will then have a web server with PHP5 available. Installing your WebserverĪll subsequent commands simply run on both webservers so that the installations are the same. With the configuration you have a working HAProxy. At the end of the file, create a few listeners and create the corresponding backend services.

You can skip both the global and the defaults section. First open the file ‘haproxy.cfg’ and get a brief overview. You can find all configuration files in ‘/ etc / haproxy’. Inet addr:10.0.0.1 Bcast:10.0.0.255 configure some bindings on your HAProxy so that we can provide a service with different configuration options per binding afterwards. Restarting networking (via systemctl): ifconfigĮth0 Link encap:Ethernet HWaddr 1e:db:db:8b:c1:01Įth1 Link encap:Ethernet HWaddr 1e:db:db:8b:c1:02 Then restart the network and check whether the interface eth1 is configured. Just edit the file / etc / network / interfaces and insert: auto eth1 Now configure the internal network on the HAProxy server. I install some more stuff like ‘vim’ or ‘wget’, you can do without it, of course. In Debian, you simply use apt-get to install the required packages. Installation HAProxyįirst, prepare your Cloud Server with HAProxy. You can, of course, use any other distribution, such as CentOS. On my servers I installed a fresh Debian 8. If your cloud hosting provider does not provide you with internal networks, simply work with the public IP addresses of your new servers. With gridscale, you can configure internal Layer-2 networks and network your Cloud Servers internally. In this article, I use cloud servers on our platform ? but you can also use the installation and configuration on any other hosting provider. First install three new servers with your cloud hosting provider.
