rsyslog 默认情况下，需要在514端口监听UDP，所以可以把/etc/rsyslog.conf如下的注释去掉
# Provides UDP syslog reception $ModLoad imudp $UDPServerRun 514
新增以下条目： \\\\ 和haproxy.conf中的要一致
local0.* /var/log/haproxy.log local1.* /var/log/haproxy.log
# vim /etc/sysconfig/rsyslog
#SYSLOGD_OPTIONS=\
SYSLOGD_OPTIONS=\
重启rsyslog服务
# /etc/init.d/rsyslog restart
重启haproxy
# service haproxy stop
# service haproxy start
查看haproxy.log
# tail -f /var/log/haproxy.log

三、keepalived安装配置
1、在主服务器上安装keepalived
注：安装keepalived需要 gcc gcc-c++ glib* openssl-devel popt-devel libnl-devel make 依赖包。如果系统是64位的，那么可能需要32位、64位的都要安装。
# tar zxvf keepalived-1.2.12.tar.gz
# cd keepalived-1.2.12
# ./configure --prefix=/usr/local/keepalived
configure: creating ./config.status config.status: creating Makefile
config.status: creating genhash/Makefile
config.status: creating keepalived/core/Makefile config.status: creating lib/config.h config.status: creating keepalived.spec config.status: creating keepalived/Makefile config.status: creating lib/Makefile
config.status: creating keepalived/vrrp/Makefile config.status: creating keepalived/check/Makefile config.status: creating keepalived/libipvs-2.6/Makefile
Keepalived configuration ------------------------
Keepalived version : 1.2.12 Compiler : gcc
Compiler flags : -g -O2 -DFALLBACK_LIBNL1 Extra Lib : -lssl -lcrypto -lcrypt -lnl Use IPVS Framework : Yes IPVS sync daemon support : Yes
IPVS use libnl : Yes Use VRRP Framework : Yes Use VRRP VMAC : Yes SNMP support : No SHA1 support : No Use Debug flags : No
注：必须看到以下提示，说明配置正确，才能继续安装
Use IPVS Framework : Yes
IPVS sync daemon support : Yes
Use VRRP Framework : Yes

（或者修改keepalived执行命令的目录和keepalived配置文件的目录，
修改/etc/rc.d/init.d/keepalived, 寻找大约15行左右的. /etc/sysconfig/keepalived, 修改为： . /usr/local/keepalived/etc/sysconfig/keepalived, 即指向正确的文件位置 \\\\这个修改根据你的实际目录修改
修改/usr/local/keepalived/etc/sysconfig/keepalived文件，设置正确的服务启动参数 \\\\这项根据你的实际目录修改
