HAProxy만 사용시 keepalived 관련 옵션은 지워야 한다. 안지우면 deviation 발생.

haproxy 로그 설정

# to have these messages end up in /var/log/haproxy.log you will

# need to:

#

# 1) configure syslog to accept network log events. This is done

# by adding the '-r' option to the SYSLOGD_OPTIONS in

# /etc/sysconfig/syslog

#

# 2) configure local2 events to go to the /var/log/haproxy.log

# file. A line like the following can be added to

# /etc/sysconfig/syslog

#

# local2.* /var/log/haproxy.log

/etc/sysconfig/rsyslog

SYSLOGD_OPTIONS="-m 0 -r"

vi /etc/rsyslog.conf

local2.* /var/log/haproxy.log

service rsyslog restart
