ubuntu16.04安裝zookeeper

zookeeper須要java，見http://www.javashuo.com/article/p-fuaghjly-gt.html 

cd /app
wget http://mirror-hk.koddos.net/apache/zookeeper/zookeeper-3.5.5/apache-zookeeper-3.5.5-bin.tar.gz
tar zxvf apache-zookeeper-3.5.5-bin.tar.gz
mv apache-zookeeper-3.5.5-bin zookeeper
cp conf/zoo.sample.cfg conf/zoo.cfg
vim conf/zoo.cfg
mkdir data
vim data/myid
echo 1 > data/myid # 這個確保和下面的server.x後面的數字對應

vim /etc/hosts

# /etc/hosts
# 自定義Hosts
10.13.6.1     kafka-node1
10.13.6.2     kafka-node2
10.13.6.3     kafka-node3

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=/app/zookeeper/data
# 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

# 節點配置信息
server.1=kafka-node1:2888:3888
server.2=kafka-node2:2888:3888
server.3=kafka-node3:2888:3888

#server.A=B:C:D
#　其中 A 是一個數字，表示這個是第幾號服務器；
#　B 是這個服務器的 ip 地址；
#　C 表示的是這個服務器與集羣中的 Leader 服務器交換信息的端口；
#　D 表示的是若是集羣中的 Leader 服務器故障，須要一個端口來從新進行選舉，選出一個新的 Leader，而這個端口就是#用來執行選舉時服務器相互通訊的端口。
#
# 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=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

其餘2個節點同理，注意myid設置不同
