4. Edit the System log configuration

# vim/etc/rsyslog.conf

By default, the following settings will read the configuration files in the/etc/rsyslog.d/*.conf directory

$IncludeConfig/etc/rsyslog.d/*.conf

5. Create a separate configuration file for Haproxy

# vim/etc/rsyslog.d/haproxy.conf

$ModLoad IMUDP

$UDPServerRun 514

local3.*/var/log/haproxy.log

A message file is also written #如果不加下面的的配置则除了在/var/log/haproxy.log in the log

6. Configure the Rsyslog Master profile to open the remote log

# Vim/etc/sysconfig/rsyslog

Syslogd_options= "-C 2-r-M 0"

#-c 2 using compatibility mode, default is-C 5

#-r turning on remote logging

#-m 0 marks the timestamp. The unit is the minute, which is 0 o'clock, which means disabling the feature

7. Restart Haproxy and Rsyslog services

#/etc/init.d/rsyslog restart

#/etc/init.d/haproxy restart

8. View Haproxy Status

#/etc/init.d/haproxy status

Haproxy installation is complete.
