HAProxy Configuration Manager

HAProxy uses a single configuration file which makes it too difficult to manage a large number of domains. This tool will (hopefully) help in managing the configuration with ease.

Initial Setup

Clone the repository

git clone https://github.com/jyotishp/haproxy-config-generator.git

Modify the header.cfg file to include all your required defaults. Make sure to change the path to SSL certificate file to the right one.

Make sure there is some file (at least an empty one) with the name haproxy.cfg in the conf.d directory.

Create a symbolic link of haproxy.cfg to /etc/haproxy/haproxy.cfg

sudo ln -s `pwd`/conf.d/haproxy.cfg /etc/haproxy/haproxy.cfg

Optional

In case you want to have a separate directory to save your configuration, open the file haconf with any text editor and change the line base_dir = './conf.d/' to base_dir = 'path_to_conf_directory/'. If you are doing this, the symbolic link for actual configuration file should be changed accordingly.

You can also consider adding haconf to /usr/bin or /bin for ease of use. But in this case make sure you modify base_dir variable to appropriate configuration directory path in the script.

How to use

Managing Domains

Adding a domain

haconf domain add <domain> <port_number> <list_of_space_seperated_IPs>

For example, if you want to add example.iiit.ac.in pointing to 127.0.0.1 listening on port 80 haconf domain add example.iiit.ac.in 80 127.0.0.1

Deleting a domain

haconf domain del <domain>

Listing loaded domains

haconf domain list

Caution

• Work is still in progress for adding ACL rules.
• As of now, the script only handles 80 and port 443.
• Everyting on port 80 is redirected to 443 on haproxy (this won't effect the reverse proxy behaviour).
