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
