测试环境上跑一个storm和zookeeper的应用.
测试环境要求不是那么高,所以zookeeper可以和Storm在同一个系统上.
zookeeper的安装运行比较简单,以zookeeper-3.4.8为例.
cp conf/zoo_sample.cfg conf/zoo.cfg
vim zoo.cfg
# The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=/export/data/zookeeper # the port at which the clients will connect clientPort=2181 # the maximum number of client connections. # increase this if you need to handle more clients #maxClientCnxns=60 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir autopurge.snapRetainCount=2 # Purge task interval in hours # Set to "0" to disable auto purge feature autopurge.purgeInterval=1
下面这两个设置了可以减少日志的输出
autopurge.snapRetainCount=2
autopurge.purgeInterval=1
启动方法:
sh bin/zkServer.sh start
storm启动时,需要在storm.yaml中设置zookeeper的地址,就写127.0.0.1即可
storm.zookeeper.servers: - "127.0.0.1"
