1,ZooKeeper集群安装,可以参考 ZooKeeper集群环境搭建实践
2,下载https://github.com/killme2008/Metamorphosis/tree/metamorphosis-all-1.4.6.2,如果不想自己编译可以直接下载,我这里选择自己编译,主要是以后如果出现问题自己可以修改其源码,重新编译
3,maven编译,maven环境自己搜索配置好,下载all项目后需要编译其子项目metamorphosis-server-wrapper。dos环境进入其目录下mvn eclipse:eclipse,完成后导入到eclipse,用eclipse插件编译。或者直接dos该目录下执行mvn clean install -Dmaven.test.skip=true。完成后target目录下生产其jar包;
可以在工程创建lib文件夹,输入以下命令:mvn dependency:copy-dependencies -DoutputDirectory=lib (不加DoutputDirectory会默认输出到targed/dependency下)。再把install的jar包也copy到lib下。
4,完成编译后上传到服务器
需要修改conf/server.ini文件
[system]brokerId=2
numPartitions=1
serverPort=8123
ashboardHttpPort=8120
unflushThreshold=0
unflushInterval=10000
maxSegmentSize=1073741824
maxTransferSize=1048576
deletePolicy=delete,168
deleteWhen=0 0 6,18 * * ?
flushTxLogAtCommit=1
stat=true
dataPath=/data1/metaq/data
dataLogPath=/data1/metaq/log
[zookeeper]
zk.zkConnect=192.168.1.1:2181,192.168.1.2:2181,192.168.1.3:2181
zk.zkSessionTimeoutMs=30000
zk.zkConnectionTimeoutMs=30000
zk.zkSyncTimeMs=5000
;; Topics section
[topic=test]
[topic=meta-test]
集群的话需要修改上面标红部分,brokerId保证每个服务器节点上不一样就行
dataPath,dataLogPath如果自己制定,需要每台服务器mkdir
分发到个节点,在每台节点的bin下都执行metaServer.sh start
需要停止时执行metaServer.sh stop
查看状态sh metaServer.sh status
5,应用例子
