mcollective安装和使用

其实跟puppet关系不大，只不过都是puppet实验室的东西。

安装好activeMQ，只要在Master机器上安装即可。
修改activemq的配置并重启：
# vi apache-activemq-5.6.0/conf/activemq.xml
在
</persistenceAdapter>
下面增加：
<plugins>
<statisticsBrokerPlugin/>
<simpleAuthenticationPlugin>
<users>
<authenticationUser username=”mcollective” password=”secret” groups=”mcollective,everyone”/>
<authenticationUser username=”admin” password=”secret” groups=”mcollective,admin,everyone”/>
</users>
</simpleAuthenticationPlugin>
<authorizationPlugin>
<map>
<authorizationMap>
<authorizationEntries>
<authorizationEntry queue=”>” write=”admins” read=”admins” admin=”admins” />
<authorizationEntry topic=”>” write=”admins” read=”admins” admin=”admins” />
<authorizationEntry topic=”mcollective.>” write=”mcollective” read=”mcollective” admin=”mcollective” />
<authorizationEntry queue=”mcollective.>” write=”mcollective” read=”mcollective” admin=”mcollective” />
<authorizationEntry topic=”ActiveMQ.Advisory.>” read=”everyone” write=”everyone” admin=”everyone”/>
</authorizationEntries>
</authorizationMap>
</map>
</authorizationPlugin>
</plugins>
在
<transportConnector name=”openwire” uri=”tcp://0.0.0.0:61616″/>
下面增加：
<transportConnector name=”stomp” uri=”stomp://0.0.0.0:61613“/>

重启activemq：
# apache-activemq-5.6.0/bin/activemq stop
# apache-activemq-5.6.0/bin/activemq start

所有机器上安装mcollective：
# yum install mcollective mcollective-client mcollective-common rubygem-stomp

修改配置文件client.cfg：
# /etc/mcollective/client.cfg
plugin.psk = unset

connector = stomp
plugin.stomp.host = 10.24.1.47
plugin.stomp.port = 61613
plugin.stomp.user = mcollective
plugin.stomp.password = secret

修改配置文件server.cfg：
# /etc/mcollective/server.cfg
daemonize = 1
plugin.psk = unset

connector = stomp
plugin.stomp.host = 10.24.1.47
plugin.stomp.port = 61613
plugin.stomp.user = mcollective
plugin.stomp.password = secret

启动mcollective：
# service mcollective restart

密码plugin.stomp.password错误可能导致如下错误：
mcollectived[13674]: connection.receive returning EOF as nil

测试：
