haproxy doesn't start

Question

Installed a new Ubuntu 10.04 server and logging in as root I installed haproxy using apt-get.

I can run haproxy directly as a daemon but when I do /etc/init.d/haproxy start nothing happens.. not even an error message.

netstat -a shows nothing is using the http port I'm trying to balance with haproxy...

Ideas?

Edit

1. I noticed that apt-get install haproxy says this in the end:

   update-rc.d: warning: /etc/init.d/haproxy missing LSB information update-rc.d: see http://wiki.debian.org/LSBInitScripts

2. /etc/default/haproxy says ENABLED=1

Solution 1

Edit /etc/default/haproxy and make sure it has a line that says ENABLED=1 in it.

The default is ENABLED=0. This is done because haproxy has no sane default configuration, so you need to first configure it, then enable it.

Solution 2

I had the same issue, where setting ENABLED had no effect due to the "test" line always failing. Found the reason: you have to edit /etc/default/haproxy instead of the init script.

Solution 3

I know this a year old thread.. but just trying to share what i have learned..

use /etc/init.d/haproxy reload or service haproxy reload and it will reload fine.. afterall we just want it to start right ;)

Solution 4

Did you try to start it as root, or with sudo? If you are like me, you sometimes forget to add sudo to the front of the commands. I tried all your commands without sudo, and they failed as you described. However, with sudo in front of them, using a default haproxy.cfg file from install, it is now running without problems. Just thought I'd point that even with the correct configs, for me it won't go without sudo.

Solution 5

I ran into this same issue after first installing the ubuntu maintained package and then (after realizing the version did not support the feature i needed) Installing a ppa newer version of haproxy. The init.d script that i wound up with pointed to /usr/sbin/haproxy when in fact my executable was in /usr/local/sbin/haproxy. the debug output "sh -xv /etc/init.d/haproxy start" mentioned earlier made this problem pretty obvious.

I set ENABLED=1, still nothing..

Assaf, you still need to configure haproxy. If the config file is not correct, it won't start, and probably has printed errors into the system logs (check /var/log/daemon.log and /var/log/syslog)

:) yes, done as root

Why it does not start without any verbose message? It's really confusing!
