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"
