Is there a GUI for HAProxy?

I'm setting up a haproxy 1.

5.16 server on Fedora 12. It seems very easy. I'm running into problems that are similar to things that other users have posted about. See "stats.log" for changes.

This seems like a fairly fundamental issue that I can't seem to find out how to fix. I can't find anything in the docs or the man pages. Does anyone know if there is a GUI interface for haproxy, or a config file for setting it up? If not, are you running something that replaces it?

For reference: I did try using the /etc/haproxy.cfg file and I keep getting this message when I run haproxy: In haproxy 1.16 the server side includes a configuration file "haproxy.cfg" - and its name is used instead of the full path.

You can find this configuration file on the "http-servers" section of the web interface. (The file is automatically created). Its path will probably be something like /etc/haproxy.

If you want to have this server listen on another network interface than localhost, you should set up an additional network interface (say eth2) and add it to the file /etc/sysconfig/network-scripts/ifcfg-eth2. To do so, you should create it as: Code: DEVICE=eth2. TYPE=Ethernet. BOOTPROTO=static. IPADDR=10.012 NETMASK=255.0 ONBOOT=yes. #ONBOOT=yes. DEFROUTE=yes. IPV4FAILUREFATAL=no. IPV6INIT=yes. NAME=eth2. Then reboot the server. This causes haproxy to listen to interface eth2 (not eth0), so that your new network interface will be brought up before haproxy.

And that's it. Please make sure you backup your config file before rebooting.

Can you run HAProxy on Windows?

You can and I just did on my Windows machine.

The first thing to be aware of is that HAProxy doesn't work very well on Windows (and I don't mean the version you get in Debian, I mean the latest version from the official repositories), it requires 32 bits compatibility and it needs some special configuration to work properly.

HAProxy on Windows. You can get HAProxy 3.1 from the official repositories of Debian Squeeze, but you need to install it by hand. In fact, it works better to install it by hand than using apt-get because apt-get doesn't download the required third party libraries and it also makes a bunch of unnecessary dependencies:

./configure --prefix=/usr/local/haproxy make all. Sudo make install. After this, you must update the /etc/hosts file to have the correct IP for haproxy. We will create two files: /etc/hosts.local for each IP we want to use and /etc/hosts for the default one, with something like this: 10 haproxy. So we will run haproxy in the 10.10 IP, and then we will be able to check if the configuration has been done correctly by going to this IP: The response must be STATUS:UP and the process state must be CLOSED. If it's not like this, HAProxy has probably not been installed correctly. You can check if the correct IP has been set by doing: dig 10.10 If the IP is set correctly, the next step is to configure some parameters in /etc/ha.cf . There are some defaults which we'll skip for now but you can see the defaults here.

We'll edit the defaults file, adding a few lines. By default, only one process per CPU will be started (useful to avoid CPU overloads if many processes need to be handled). Also, we'll use a maxconn of 100 for the maximum number of connections HAProxy can handle.

You can check the defaults file with: cat /etc/ha.
