The default HAPROXY install will will not log to a file…

You will need to modify Rsyslog and HAProxy configuration.

  • Rsyslog: Edit /etc/rsyslog.conf 
    # rsyslog v5 configuration file
   
# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html
   
#### MODULES ####
   
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imklog   # provides kernel logging support (previously done by rklogd)
#$ModLoad immark  # provides --MARK-- message capability
   
# ENABLED THIS FOR HAPROXY LOGGING
# Provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514
$UDPServerAddress 127.0.0.1
  • HAProxy: Add /etc/rsyslog.d/haproxy with the following contents 
    $template Haproxy,"%msg%\n"
local0.=info -/var/log/haproxy/haproxy.log;Haproxy
local0.notice -/var/log/haproxy/haproxy-status.log;Haproxy
### keep logs in localhost ##
local0.* ~
  • After the changes, you will need to restart both HAProxy and Rsyslog.
