haproxy各应用场景配置实例
一、http服务器配置示例#---------------------------------------------------------------------
#Global settings
#---------------------------------------------------------------------
global
# to have these messages end up in/var/log/haproxy.log you will
# need to:
#
# 1) configure syslog to accept network logevents.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
#
