使用root权限

su -
visodu
在 root    ALL=(ALL)       ALL 下添加
your_login_name    ALL=(ALL)       ALL

sudu -i

ip地址端口设计
192.168.56.19  63631  61616  8161
192.168.56.20  63631  61616  8161
192.168.56.21  63631  61616  8161

配置防火墙

vim /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 63631 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 61616 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8161 -j ACCEPT 
service iptables restart

三台机器下载安装包到usr/local/src
apache-activemq-5.11.1-bin.tar.gz

解压安装文件
cd /usr/local/src
tar -zxvf apache-activemq-5.11.1-bin.tar.gz
mv apache-activemq-5.11.1 ../mq-node-01
mv apache-activemq-5.11.1 ../mq-node-02
mv apache-activemq-5.11.1 ../mq-node-03

赋予activemq执行权限
chmod 755 /usr/local/mq-node-01/bin/activemq
chmod 755 /usr/local/mq-node-02/bin/activemq
chmod 755 /usr/local/mq-node-03/bin/activemq
 

配置集群使用leveldb
修改三台机器配置文件
brokerName="xxxxx" 名字保证一样

vim /usr/local/mq-node-01/conf/activemq.xml
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="xxxxx" dataDirectory="${activemq.data}">

。。。。。。。。。
 
<persistenceAdapter> 
<!-- kahaDB directory="${activemq.data}/kahadb"/ --> 
 <replicatedLevelDB
           directory="${activemq.data}/leveldb"
           replicas="3"
           bind="tcp://0.0.0.0:63631"
           zkAddress="192.168.56.19:2181,192.168.56.20:2181,192.168.56.21:2181"
           hostname="192.168.56.19"
           zkPath="/activemq/leveldb-stores"
           />
</persistenceAdapter> 

。。。。。。。
</broker> 

vim /usr/local/mq-node-02/conf/activemq.xml

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="xxxxx" dataDirectory="${activemq.data}"> 
。。。。。。。。。
<persistenceAdapter> 
<!-- kahaDB directory="${activemq.data}/kahadb"/ --> 
 <replicatedLevelDB
           directory="${activemq.data}/leveldb"

           hostname="192.168.56.20"
           zkPath="/activemq/leveldb-stores"
           />
</persistenceAdapter> 
。。。。。。。。。
</broker>

vim /usr/local/mq-node-03/conf/activemq.xml 

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="xxxxx" dataDirectory="${activemq.data}"> 
。。。。。。。。。
<persistenceAdapter> 
<!-- kahaDB directory="${activemq.data}/kahadb"/ --> 
 <replicatedLevelDB
           directory="${activemq.data}/leveldb"
           replicas="3"
           bind="tcp://0.0.0.0:63631"
           zkAddress="192.168.56.19:2181,192.168.56.20:2181,192.168.56.21:2181"
           hostname="192.168.56.21"
           zkPath="/activemq/leveldb-stores"
           />
</persistenceAdapter> 
。。。。。。。。。
</broker>

启动activemq
/usr/local/mq-node-01/bin/activemq start
/usr/local/mq-node-02/bin/activemq start
/usr/local/mq-node-03/bin/activemq start

查看日志
tail -f /usr/local/mq-node-01/data/activemq.log
tail -f /usr/local/mq-node-02/data/activemq.log
tail -f /usr/local/mq-node-03/data/activemq.log

管控台地址和密码
http://192.168.56.19:8161 

http://192.168.56.20:8161

http://192.168.56.21:8161

默认用户名和密码为：admin/admin 

使用密码访问activemq(可选，建议配置)
vim /usr/local/mq-node-01/conf/activemq.xml 
vim /usr/local/mq-node-02/conf/activemq.xml 
vim /usr/local/mq-node-03/conf/activemq.xml 

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="xxxxx" dataDirectory="${activemq.data}">

。。。。。。。。

<plugins>
  <simpleAuthenticationPlugin> 
  <users> 
    <authenticationUser username="xxx" password="xxxxxx" groups="users,admins"/> 
  </users> 
  </simpleAuthenticationPlugin> 
</plugins>

。。。。。。。。

</broker>

修改管控台密码(可选，建议配置)

确保 authenticate 的值为 true（默认） 
vim /usr/local/mq-node-01/conf/jetty.xml 
vim /usr/local/mq-node-02/conf/jetty.xml 
vim /usr/local/mq-node-03/conf/jetty.xml 

<bean id="securityConstraint" class="org.eclipse.jetty.util.security.Constraint"> 
    <property name="name" value="BASIC" /> 
    <property name="roles" value="admin" /> 
    <property name="authenticate" value="true" /> 
</bean> 

vim /usr/local/mq-node-01/conf/jetty-realm.properties
vim /usr/local/mq-node-02/conf/jetty-realm.properties 
vim /usr/local/mq-node-03/conf/jetty-realm.properties  

# Defines users that can access the web (console, demo, etc.) 
# username: password [,rolename ...] 
admin:xxxxx, admin 
 
注意:用户名和密码的格式是 
用户名 : 密码 ,角色名 

重启
/usr/local/mq-node-01/bin/activemq restart 
/usr/local/mq-node-02/bin/activemq restart 
/usr/local/mq-node-03/bin/activemq restart 
设置开机启动(可选，建议配置)
vi /etc/rc.local 

## ActiveMQ
/usr/local/mq-node-01/bin/activemq  start
/usr/local/mq-node-02/bin/activemq  start
/usr/local/mq-node-03/bin/activemq  start

java访问地址
failover:(tcp://192.168.56.19:61616,tcp://192.168.56.20:61616,tcp://192.168.56.21:61616)?randomize=false
