HAProxy will hangs when I upgrade to pfsense 2.3.4
-
@Cow:
Manually downgraded to haproxy-1.7.2 provided in pfSense 2.3.3 "fix" the service.
pkg add https://pkg.pfsense.org/pfSense_v2_3_3_amd64-pfSense_v2_3_3/All/haproxy-1.7.2.txzWARNING: Running the command above may break your package dependency and break your firewall. Do not run the command on production environment.
I am not sure if it is a config / local problem or not.
Needs more confirmation.I'm having the same problem.
If I try to install the older version I get a notification that haproxy is already installed.
Is there a way to install the older version while keeping the config? -
I also am having the same issue. It hangs the pfsense box. Any idea when we could expect a fix so it starts working again in 2.3.4?
haproxy is a great product and we use it extensively, I presume it has to be upgraded to work properly with 2.3.4.
Running : Pfsense 2.3.4
Haproxy: 1.7.4 pfsense package 0.52_7Thanks
-
The same problem at my site, also having pfSense 2.3.4, HAProxy 1.7.4.
To be exact, just WebGUI hangs and the WebGUI restart or php-fpm restart (console option 11 or 16) returns it to be responsive again.
And as @Cow mentioned, running HAProxy in foreground or debug mode manually is a quick workaround, but no long-term solution.
-
Those of you experiencing this problem, can you post more about both your GUI and your HAProxy configurations?
Is HAProxy handling your GUI connections in some way? Or is your GUI on an alternate port? Do you have the HAProxy dashboard widget active?
Need some more specifics about the HAProxy end of things as well, general config info, frontend/backend config, etc.
Since the same version of HAProxy (1.7.4) is also on 2.4, I'd be curious to know if anyone has a problem with that as well, or if it's working as expected.
-
HAProxy is not handling any GUI connections for pfSense (it is only active as a reverse proxy and installed through the packages supplied in pfSense).
I had the dashboard widget active, but I have removed it cause it was noticed that it could possibly be a solution.I do not feel confortable sharing all my config from haproxy, but I'm using a shared frontend on port 443 for multiple backends.
The backend consists of multiple different web servers on different ports (some connections are plain http, some are https).Other common settings:
Enable HAProxy: ticked
Maximum connections: 1024
Carp monitor: disabled
Internal stats port: 2200
Syslog has been setup.
DNS servers have been entered in the Global DNS resolvers list.
No mail configurated

That's fine, I don't need all of your specifics, mostly what I mentioned: Listening port(s) for the GUI and haproxy and if they are connected in some way, and answers to my other questions.
I setup a simple haproxy instance on 2.4 with the widget, SSL offloading to a backend server, and it works fine there. I'll have to setup another web server to test 2.3.4, but I'd like to know more about how you have the haproxy and GUI daemons set to listen/bind on the firewall at least.
-
Hmmm. With a pretty simple setup with SSL offloading here, this works just fine as always. Then I have another fairly complicated one with lots of backends, multiple frontends and the pfSense GUI itself behind HAproxy plus the LUA ACME plugin, this works perfectly fine as well.
Both have HAproxy on 80/443 and GUI at 4443, the HTTP => HTTPS redirect disabled for webGUI.

here is my binding if it can help.

I'm having the same issue. I run haproxy on port 4343 which doesn't conflict with any other ports.
I'd also like to know more about these awesome domains:
acl dragondreams_acl hdr_end(host) -i dragondreams.ca
acl dragondoodles_acl hdr_end(host) -i dragondoodles.ca -
[…]
listen HAProxyLocalStats
bind 127.0.0.1:8080 name localstats
[…]
frontend httpWEBSites
bind 127.0.0.1:8080 name 127.0.0.1:8080
[…]Should your stats and a live frontend really be bound to the same port? Try moving the stats to port 2200. HAProxy may be smart enough to do the right thing there, but it's better not to tempt fate.

Is that a typo? That should probably be 2048. Otherwise it seems sane.

Yeah, it was a typo :-\

I searched my log files from the long saturday night - the only message that I could find related and suspect are problems before reboot like
2017-05-06 23:40:30 Error (3) PHP-CGI rc.initial.reboot: The command '/usr/local/etc/rc.d/haproxy.sh stop' returned exit code '1', the output was 'Stopping haproxy. Waiting for PIDS: 76571\. Stopping haproxy. No matching processes were found'My config is running fine after degrading to 1.7.2 - it's a very basic setup with two backends online and ssl/https frontend with sni.

I reproduced the issue on a fresh install. It seems that there is a problem with DNS resolvers of haproxy.
1. Install a fresh pfSense 2.3.4-RELEASE (amd64)
2. Install haproxy from package manager
3. Add a backend with your favourite web server
3. Add a HTTP frontend, listen to any:8080, set the default backend.
4. Check Enable HAProxy, Maximum connections: 500, Internal stats port: 2200
5. In the DNS servers section: click new server, Name: local, DNSserver:127.0.0.1, DNSport:53
6. Apply changes.
7. HAProxy looks like up and running.
8. Setup firewall rules and visit port 8080 / 2200. No response.
9. Visit haproxy stats page few times, and webConfigurator should hang now.–
EDIT: amd64. -
OK, that I can reproduce on 2.3.4 and 2.4. The key is having the DNS resolver configured inside haproxy. It appears to get hung up attempting to query the UNIX socket for stats. Even if I try to hit that manually, it never receives a response. If I start haproxy manually in the foreground (Disable daemon mode), the stats command succeeds.
-
I can also confirm that if I remove the DNS entries in Haproxy it no longer hangs pfsense. However, it is still not routing the calls to any internal server. I presume the daemon issue still exist.
-
However, it is still not routing the calls to any internal server.
Does it show a 503 service unavailable error?
–-
EDIT: Could you try disabling ssl offloading (if enabled) and see if it work or not? -
Got it to work, Had a typo (SSL) and once fixed everything seems to work like normal as long as I do not add any DNS entries into haproxy.
Thanks for all the help, much appreciated.

FYI- Same problem with haproxy 1.7.4 on plain FreeBSD, so not specific to our package. I did just copy over the config and adjust though, so it could be in one of the directives there but nothing seems obvious yet. Still trying things out.
