机器为 172.25.1.23 172.25.1.24 172.25.1.28 可以在/conf/users.properties中寻找 http://172.25.1.28:8161/index.html admin admin
TCP端口61616(主从集群172.25.1.23,172.25.1.24,172.25.1.28) 管理端口8161
软件下载 zookeeper下载地址: https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz Activemq下载地址 http://activemq.apache.org/components/classic/download/
首先需要初始化系统及安装JDK，并配置环境变量
export JAVA_HOME=/opt/app/jdk1.8.0_251 export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
1、zookeeper安装 解压apache-zookeeper-3.6.1-bin.tar.gz /opt/app/zookeeper
cp /opt/app/zookeeper/conf/{zoo_sample,zoo}.cfg 修改为zoo.cfg文件如下 dataDir=/opt/app/zookeeper/data dataLogDir=/opt/app/zookeeper/logs
server.1=172.25.1.23:2888:3888 server.2=172.25.1.24:2888:3888 server.3=172.25.1.28:2888:3888 admin.serverPort=8888
同步至其它两台服务器 然后再修改以下相关参数
10.23 echo "1" >>/opt/app/zookeeper/data/myid 10.24 echo "2" >>/opt/app/zookeeper/data/myid 10.28 echo "3" >>/opt/app/zookeeper/data/myid
2、activemq安装 解压apache-activemq-5.16.0-bin.tar.gz至 /opt/app/activemq目录下面 进入/opt/app/activemq/conf目录 cp activemq.xml activemq.xml_bak 修改activemq.xml <persistenceAdapter> <!-- <kahaDB directory="${activemq.data}/kahadb"/> --> <replicatedLevelDB directory="${activemq.data}/leveldb" replicas="3" bind="tcp://0.0.0.0:0" zkAddress="172.25.1.23:2181,172.25.1.24:2181,172.25.1.28:2181" zkPath="/activemq/leveldb-stores" hostname="172.25.1.23" /> #注意hostname修改为各个主机的IP地址 修改jetty.xml cp jetty.xml jetty.xml_bak vi jetty.xml 将localhost修改为0.0.0.0 <property name="host" value="0.0.0.0"/>
3、activemq同步并启动 activemq同步至其它两台服务器 并修改activemq.xml配置文件 hostname=
启动
cd /opt/app/activemq/bin ./activemq start
三台都执行 只有一台提供服务 同步8161也只有一台可以打开
可以在/conf/users.properties中寻找 http://172.25.1.28:8161/index.html admin admin
出现以下报错就别折腾了，换版本为apache-activemq-5.15.9-bin.zip zookeeper也可以换一个低版本的。 至于以下报错，没有查出来是什么原因。 包括最新版本同样有这样的报错。 就是在三台中，把master杀掉后，slave不能自动接管。直接报错。 清理zk和data下面的以及修改日志，都不能解决。 只有换低一点版本。
以上文档，是用了最新的版本，但有问题，只是不想去改文档 ，直接换成apache-activemq-5.15.9-bin.zip
