We can distribute the load across many servers. Our frontend section is configured, via its default_backend directive, to forward requests to a pool of servers defined in a backend section called webservers. You can read about acl directive for more details. If you want to divert users from different countries to different server locations, you can use access control lists acl directive in the frontend section.

We can also add an option forwardfor directive to the defaults section so that it applies across the board to all proxies. Then the web server can look for and parse this header to get the original, client IP address. To do this, we added a header called forwardfor to the incoming request before it is passed along to the web servers. We don't want to log our proxy server's IP address. We also want to capture the client's source IP address in our web server's logs. You can add as many bind directives to frontend as you want. You can use either an IP address or an asterisk *, which means any IP address configured on this machine. Open /etc/haproxy/haproxy.cfg configuration file: sudo vi /etc/haproxy/haproxy.cfgĪdd the following lines to the bottom of the /etc/haproxy/haproxy.cfg file: frontend firstbalance We will have it listen on the HAProxy IP address at port 80.

listen: A shorthand notation which combines frontend and backend features into a single command.

backend: Defines a pool of servers that the frontend will forward requests to.

frontend: Defines a reverse proxy which will listen for incoming requests on a specific IP address and port.

In addition to global and defaults you can add: Now let's put HAProxy in front of your web server(s).Īt the bottom of the /etc/haproxy/haproxy.cfg file, below the configurations listed above, we will add one or more new sections. The defaults section contains all of the proxies settings.Īfter editing /etc/haproxy/haproxy.cfg, restart the haproxy service for the changes to take effect: sudo service haproxy restart This section contains user, group, log directives, and stats. The global section contains settings that apply to the HAProxy process itself.

The following /etc/haproxy/haproxy.cfg file starts a server with the default settings: global The HAProxy main configuration file is located at /etc/haproxy/haproxy.cfg. You can also find created files in the following locations: /etc/default/haproxy

Install the haproxy package with following command: sudo apt-get -y install haproxyĪfter installation, verify that HAProxy is working: haproxy -v Shell access to the server using either SSH or the DCD's remote console.A provisioned server running Ubuntu 16.04 LTS.Familiarity with the ProfitBricks Data Center Designer (DCD).For more information, read this article on the DCD Load Balancer Component. Note: If your load balancing needs are minimal, and a basic round-robin set-up will cover your requirements, you may want to use the load balancer component in the ProfitBricks DCD instead. It has several features which allow it to work well with web traffic, such as its ability to inspect and direct clients based on their HTTP messages. HAProxy is a free, open-source reverse proxy and load balancer with the ability to handle hundreds of thousands of simultaneous connections. Enable your website or service to handle more traffic.

Let you do maintenance, upgrade software, deploy websites, or swap out servers without disrupting service.

Reduce the load on each individual machine.

Load balancing provides better performance, availability, and redundancy because it spreads work among many back-end servers. This tutorial will cover an overview of the features and benefits of using load balancing with HAProxy.
