Zookeeper+ActiveMQ 集羣實現

基礎環境：

系統環境：centos6.7

軟件包:zookeeper-3.4.10.tar.gz

ZooKeeper集羣

主機ip	消息端口	通訊端口
192.168.33.17	2181	2888：3888
192.168.33.18	2181	2888：3888
192.168.33.19	2181	2888：3888

ActiveMq集羣

主機ip	集羣間的通訊端口	消息端口	控制檯端口
192.168.33.17	62621	61616	8161
192.168.33.18	62621	61616	8161
192.168.33.19	62621	61616	8161

zookeeper集羣安裝配置（須要在全部集羣節點配置）：

0.ZooKeeper依賴於Java,請先安裝好java，並配置好環境變量。

1.配置ZooKeeper環境變量

# vim /etc/profile
export ZOOKEEPER=/usr/local/zookeeper-3.4.10
export PATH=$ZOOKEEPER/bin:$PATH

2.修改配置文件名

mv zoo_sample.cfg zoo.cfg

3. 修改配置文件

vim zoo.cfg

主要修改兩個地方,以下：

(1)data文件目錄默認不存在須要手動建立

dataDir=/usr/local/zookeeper-3.4.10/data

 

(2)配置文件最後增長集羣服務器ip及端口信息

server.1=192.168.33.17:2888:3888
server.2=192.168.33.18:2888:3888
server.3=192.168.33.19:2888:3888

4.在Zookeeper主目錄下建立data目錄

mkdir data
cd data/

在data文件夾下創建myid(三個節點，0，1，2)

#vim myid

0

5.啓動zookeeper

cd /usr/local/zookeeper-3.4.10/bin
./zkServer.sh start

6.查看ZooKeeper進程

[root@localhost bin]# jps
2406 QuorumPeerMain
2487 Jps

7.查看節點狀態(能夠看到該節點角色爲master)

# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper-3.4.10/bin/../conf/zoo.cfg
Mode: leader

 

ActiveMQ集羣配置：

1.vim usr/local/activemq5.15/conf/activemq.xml

(1)修改brokerName,三臺機器的brokerName相同,都爲"activemq-cluster"

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

(2)修改數據庫爲replicatedLevelDB

注:hostname 填寫本機的ip

<persistenceAdapter>
<!--
            <kahaDB directory="${activemq.data}/kahadb"/>
-->

        <replicatedLevelDB
                directory="${activemq.data}/leveldb"
                replicas="3"
                bind="tcp://0.0.0.0:62621"
                zkAddress="192.168.33.17:2181,192.168.33.18:2181,192.168.33.19:2181"
                hostname="192.168.33.19"
                zkPath="/activemq/leveldb-stores"
/>
        </persistenceAdapter>

2.三臺mq機器分別啓動mq服務

/usr/local/activemq5.15/bin/activemq start

3.集羣測試

訪問http://192.168.33.17:8161/

http://192.168.33.18:8161/

http://192.168.33.19:8161/

能夠發現只有一臺機器可以訪問到，則集羣配置成功

4.zookeeper client端，查看zookeeper集羣信息

 zkCli.sh

[zk: localhost:2181(CONNECTED) 4]  ls /activemq/leveldb-stores
[00000000002, 00000000003, 00000000001]

能夠看到有三個節點信息

5.經過idea,安裝zookeeper插件，也能夠查詢到ActiveMq集羣信息

01

{"id":"activemq-cluster","container":null,"address":"tcp://192.168.33.18:62621","position":-1,"weight":1,"elected":"0000000001"}

02

{"id":"activemq-cluster","container":null,"address":null,"position":-1,"weight":1,"elected":null}

03

{"id":"activemq-cluster","container":null,"address":null,"position":-1,"weight":1,"elected":null}

能夠看到，192.68.33.18爲目前active的機器。
