环境 ：

1、2台centos6.5虚拟机已装好puppet

选用rabbitMQ

安装过程：

1、安装rabbitmq 

yum install erlang

yum install rabbitmq-server

/etc/rc.d/init.d/rabbitmq-server start #启动rabbitmq服务

/etc/rc.d/init.d/rabbitmq-server status #查看rabbitmq状态

加载amqp_client和rabbit_stomp插件

ln -s /usr/lib/rabbitmq/lib/rabbitmq_server-3.1.5/sbin/rabbitmq-plugins /usr/sbin/rabbitmq-plugins #创建命令rabbitmq-plugins的软连接

ln -s /usr/lib/rabbitmq/lib/rabbitmq_server-3.1.5/sbin/rabbitmq-env /usr/sbin/rabbitmq-env #创建命令rabbitmq-env的软连接

rabbitmq-plugins enable rabbitmq_stomp #开启rabbitmq_stomp插件

rabbitmq-plugins enable rabbitmq_management #开启rabbitmq_management插件为后边建立exchanges队列最准备

默认的登录用户名密码均为guest

/etc/rc.d/init.d/rabbitmq-server restart

tailf /var/log/rabbitmq/rabbit\@puppetserver.log #可以从日志看到stomp插件加载成功,而且能够查到遇到的错误原因，根据原因去google就能找到问题原因。

 创建rabbitmq.config配置文件，修改监听端口为61613

vim /etc/rabbitmq/rabbitmq.config

[ 

 {rabbitmq_stomp, [{tcp_listeners, [61613]}]} 

].

/etc/rc.d/init.d/rabbitmq-server restart

netstat -nlp | grep beam #默认监听端口为61613

删除默认账户guest，为MCollective创建账户“mcollective”并设置密码为“secret”，然后设置权限。

创建虚拟主机组
rabbitmqctl  add_vhost /mcollective
Creating vhost "/mcollective" ...
...done.

设置用户访问虚拟主机组的权限
 rabbitmqctl set_permissions -p "/mcollective" mcollective ".*" ".*" ".*"
Setting permissions for user "mcollective" in vhost "/mcollective" ...
...done.

[root@puppetserver rpms]# rabbitmqctl delete_user guest Deleting user "guest" ... ...done. [root@puppetserver rpms]# rabbitmqctl add_user mcollective secret Creating user "mcollective" ... ...done. [root@puppetserver rpms]# rabbitmqctl set_permissions -p "/" mcollective ".*" ".*" ".*" Setting permissions for user "mcollective" in vhost "/" ... ...done. [root@puppetserver sbin]# rabbitmqctl list_users #查看监听用户 Listing users ... mcollective [] ...done.

我的/etc/mcollective/cilent.cfg配置文件

main_collective = mcollective

collectives = mcollective

libdir = /usr/libexec/mcollective

logger_type = console

loglevel = warn

# Plugins

securityprovider = psk

#plugin.psk = unset

plugin.psk = a36cd839414370e10fd281b8a38a4f48

connector = rabbitmq

plugin.rabbitmq.vhost = /mcollective

plugin.rabbitmq.pool.size = 1

plugin.rabbitmq.initial_reconnect_delay = 0.01

plugin.rabbitmq.max_reconnect_delay = 30.0

plugin.rabbitmq.use_exponential_back_off = true

plugin.rabbitmq.max_reconnect_attempts = 0

plugin.rabbitmq.randomize = false

plugin.rabbitmq.timeout = -1

plugin.rabbitmq.pool.1.host = master.wei.com

plugin.rabbitmq.pool.1.port = 61613

plugin.rabbitmq.pool.1.user = mcollective

plugin.rabbitmq.pool.1.password = secret

plugin.rabbitmq.pool.1.ssl = false

# Facts

factsource = yaml

plugin.yaml = /etc/mcollective/facts.yaml

/etc/mcollective/server.cfg配置文件

main_collective = mcollective

collectives = mcollective

libdir = /usr/libexec/mcollective

logfile = /var/log/mcollective.log

loglevel = info

daemonize = 1

# Plugins

securityprovider = psk

#plugin.psk = unset

plugin.psk = a36cd839414370e10fd281b8a38a4f48

connector = rabbitmq

plugin.rabbitmq.vhost = /mcollective

plugin.rabbitmq.pool.size = 1

plugin.rabbitmq.initial_reconnect_delay = 0.01

plugin.rabbitmq.max_reconnect_delay = 30.0

plugin.rabbitmq.use_exponential_back_off = true

plugin.rabbitmq.max_reconnect_attempts = 0

plugin.rabbitmq.randomize = false

plugin.rabbitmq.timeout = -1

plugin.rabbitmq.pool.1.host = master.wei.com

plugin.rabbitmq.pool.1.port = 61613

plugin.rabbitmq.pool.1.user = mcollective

plugin.rabbitmq.pool.1.password = secret

plugin.rabbitmq.pool.1.ssl = false

# Facts

factsource = yaml

plugin.yaml = /etc/mcollective/facts.yaml

服务端重启mcollective服务 service mcollective restart

client端mco ping

就说明可以了。

安装的时候遇到的问题：

一、

这错误是由于新版本2.5.2以上连接mq是不支持用stomp方式去连的

将配置文件中的connector用rabbitmq

二、

注意：启用rabbitmq-management插件时会把你前面建立的用户mcollective删掉，这是你需要重新建立mcollective用户。
