Does HAProxy support logging to a file?
I've just installed haproxy on my test server.
Is there a way of making it write its logs to a local file, rather than syslog?
This is only for testing so I don't want to start opening ports / cluttering up syslog with all my test data.
Unfortunately, the only information I can find all revolves around logging to a syslog server.
I tried using:
log /home/user/ha.log local0
in my config. But that told me:
[ALERT] 039/095022 (9528) : sendto logger #1 failed: No such file or directory (errno=2)
When I restarted. So I created the file with touch /home/user/ha.log
and restarted at which point I got:
[ALERT] 039/095055 (9593) : sendto logger #1 failed: Connection refused (errno=111)
Is this possible, or am I going to have to configure syslog etc. to see my test data?

I don't think HAProxy can log to a file, and I suspect the reason for this is that writes to disk are a blocking operation. Why do you really not want to use syslog? Config is not all that tricky. You can assign a local facility to HAProxy and configure your syslog daemon to write those entries to a different file, and not to other syslog files (or network streams), if you're not wanting the HAProxy logs not to be mixed in with everything else.

Haproxy simply doesn't support logging to files.
As stated in the documentation (https://cbonte.github.io/haproxy-dconv/1.8/configuration.html#3.1-log), the "log" statement takes as first parameter an address.
If that's a file, it's a unix socket and HAProxy will speak in the syslog format to this socket.
Haproxy is designed like this because its responsability is to proxy requests, not write files, it delegates writing of log files to syslog.
If you don't want to mess with your machine, you can for example install logstash and run:
logstash -e 'input { unix { path => "/tmp/haprxoy_log.sock" } } output { stdout { } }'
and add:
log /tmp/haprxoy_log.sock
In your haproxy.cfg to test it.

You can change haproxy log config file under /etc/rsyslog.d/
to point the file to the path you like. Not sure about other distribution. For me, I'm using Debian. I changed /etc/rsyslog.d/49-haproxy.conf
to point to /var/log/haproxy/haproxy.log
,
# Create an additional socket in haproxy's chroot in order to allow logging via
# /dev/log to chroot'ed HAProxy processes
$AddUnixListenSocket /var/lib/haproxy/dev/log
# Send HAProxy messages to a dedicated logfile
if $programname startswith 'haproxy' then /var/log/haproxy/haproxy.log
&~
You should also update the log path in /etc/logrotate.d/haproxy
to the new path. So that it will rotate and compress logfile in newly configured path using gzip
.
Then restart rsyslog.service.
sudo systemctl restart rsyslog.service
Now haproxy.log.*
file will be in /var/log/haproxy/

I don't think HAProxy can log to a file, and I suspect the reason for this is that writes to disk are a blocking operation. Why do you really not want to use syslog? Config is not all that tricky. You can assign a local facility to HAProxy and configure your syslog daemon to write those entries to a different file, and not to other syslog files (or network streams), if you're not wanting the HAProxy logs not to be mixed in with everything else.
