測(cè)試環(huán)境上跑一個(gè)storm和zookeeper的應(yīng)用.
測(cè)試環(huán)境要求不是那么高,所以zookeeper可以和Storm在同一個(gè)系統(tǒng)上.
zookeeper的安裝運(yùn)行比較簡(jiǎn)單,以zookeeper-3.4.8為例.
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
下面這兩個(gè)設(shè)置了可以減少日志的輸出
autopurge.snapRetainCount=2
autopurge.purgeInterval=1
啟動(dòng)方法:
sh bin/zkServer.sh start
storm啟動(dòng)時(shí),需要在storm.yaml中設(shè)置zookeeper的地址,就寫127.0.0.1即可
storm.zookeeper.servers: - "127.0.0.1"
