rabbitmq部署在机房，添加镜像集群后，需要做高可用，当单机故障时可以切换到另外一台
1.修改rabbitmq的配置，引入修改相关配置的文件
# vim /usr/local/rabbitmq/sbin/rabbitmq-defaults
# 添加这行
CONFIG_FILE=${SYS_PREFIX}/etc/rabbitmq/rabbitmq.conf
# 添加修改端口的配置
vim /usr/local/rabbitmq/etc/rabbitmq/rabbitmq.conf
#数据管理端口（默认端口为5672）
listeners.tcp.default=5673
#界面管理端口（默认端口为15672）
management.tcp.port=15672
management.tcp.ip=0.0.0.0
chown -R rabbitmq.rabbitmq /etc/rabbitmq/
2.配置负载均衡程序haproxy
添加haproxy的相关配置
useradd haproxy -s /sbin/nologin
# 编写 haproxy 的启动脚本
vim /etc/init.d/haproxy
#!/bin/sh## chkconfig: - 85 15# description: HA-Proxy is a TCP/HTTP reverse proxy which is particularly suited \# for high availability environments.# processname: haproxy# config: /etc/haproxy/haproxy.cfg# pidfile: /var/run/haproxy.pid# Script Author: Simon Matter <simon.matter@invoca.ch># Version: 060600# Source function library.if [ -f /etc/init.d/functions ]; then. /etc/init.d/functionselif [ -f /etc/rc.d/init.d/functions ] ; then. /etc/rc.d/init.d/functionselseexit 0fi# Source networking configuration.. /etc/sysconfig/network# Check that networking is up.[ ${NETWORKING} = "no" ] && exit 0# This is our service nameBASENAME=`basename $0`if [ -L $0 ]; thenBASENAME=`find $0 -name $BASENAME -printf %l`BASENAME=`basename $BASENAME`fiBIN=/usr/sbin/$BASENAMECFG=/etc/$BASENAME/$BASENAME.cfg[ -f $CFG ] || exit 1PIDFILE=/var/run/$BASENAME.pidLOCKFILE=/var/lock/subsys/$BASENAMERETVAL=0start() {quiet_checkif [ $? -ne 0 ]; thenecho "Errors found in configuration file, check it with '$BASENAME check'."return 1fiecho -n "Starting $BASENAME: "daemon $BIN -D -f $CFG -p $PIDFILERETVAL=$?echo[ $RETVAL -eq 0 ] && touch $LOCKFILEreturn $RETVAL}stop() {echo -n "Shutting down $BASENAME: "killproc $BASENAME -USR1RETVAL=$?echo[ $RETVAL -eq 0 ] && rm -f $LOCKFILE[ $RETVAL -eq 0 ] && rm -f $PIDFILEreturn $RETVAL}restart() {quiet_checkif [ $? -ne 0 ]; thenecho "Errors found in configuration file, check it with '$BASENAME check'."return 1fistopstart}reload() {if !

3.添加haproxy的配置
# cat /etc/haproxy/haproxy.cfg #---------------------------------------------------------------------# Global settings#---------------------------------------------------------------------global# 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#log 127.0.0.1 local2chroot/usr/local/haproxypidfile/usr/local/haproxy/haproxy.pidmaxconn50000user haproxygroup haproxydaemonnbproc1# turn on stats unix socketstats socket /usr/local/haproxy/stats#---------------------------------------------------------------------# common defaults that all the 'listen' and 'backend' sections will# use if not designated in their block#---------------------------------------------------------------------defaultsmodetcplog global# option httplogoption tcplogoption dontlognulloption http-server-close# option forwardfor except 127.0.0.0/8# optionredispathretries 3timeout queue 1mtimeout connect 10stimeout client2mtimeout server2mtimeout http-keep-alive 10stimeout check 10smaxconn 3000#---------------------------------------------------------------------# HAProxy statistics backend#---------------------------------------------------------------------listen haproxy-monitoring bind *:4321mode httpstats enablestats refresh 30sstats uri/statsstats realm HAProxy\ Statisticsstats auth admin:adminstats hide-version#---------------------------------------------------------------------# main frontend which proxys to the backends#---------------------------------------------------------------------listen rabbitmq_cluster bind 0.0.0.0:5672mode tcpbalance roundrobinserver rabbitmq_01 192.168.254.187:5673 check inter 2000 rise 2 fall 3server rabbitmq_02 192.168.254.196:5673 check inter 2000 rise 2 fall 3#---------------------------------------------------------------------# main frontend which proxys to the backends#---------------------------------------------------------------------listen rabbitmq_webbind 0.0.0.0:27651mode tcpbalance roundrobinserver rabbitmq_01 192.168.254.187:15672 check inter 2000 rise 2 fall 3server rabbitmq_02 192.168.254.196:15672 check inter 2000 rise 2 fall 3#---------------------------------------------------------------------# round robin balancing between the various backends
# 配置开机自动启动
chkconfig --add haproxy
chkconfig haproxy on
chkconfig --list haproxy
4.配置keepvid
# 自动启动haproxy的监控脚本
mkdir /etc/keepalived/
vim /etc/keepalived/check_haproxy.sh
#!/bin/bashA=`ps -C haproxy --no-header | wc -l`if [ $A -eq 0 ];then#/usr/local/haproxy/sbin/haproxy -f /etc/haproxy/haproxy.cfg &killall haproxy/etc/init.d/haproxy startecho "haproxy start done" >>/etc/haproxy/haproxy_start.logsleep 3if [ `ps -C haproxy --no-header | wc -l` -eq 0 ];then/etc/init.d/keepalived stopecho "keepalived stop"fifi
chmod +x /etc/keepalived/check_haproxy.sh
# keepalived的启动文件
