zookeeper搭建

1、解压

tar -zxf zookeeper-3.4.6.tar.gz

2、修改配置文件

[root@cluster3 hadoop]# cd zookeeper-3.4.6/conf/
[root@cluster3 conf]# cp zoo_sample.cfg zoo.cfg
[root@cluster3 conf]# vi zoo.cfg 

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
server.1=cluster1:2888:3888
# 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=/usr/local/hadoop/zookeeper-3.4.6/data
dataLogDir=/usr/local/hadoop/zookeeper-3.4.6/logs
# the port at which the clients will connect
clientPort=2181
server.4=cluster4:2888:3888
server.5=cluster5:2888:3888
# 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=3
# Purge task interval in hours
"zoo.cfg" 30L, 1011C written

3、修改myid

[root@cluster3 conf]# cd /usr/local/hadoop/zookeeper-3.4.6/data
[root@cluster3 data]# vi myid
3

[root@cluster3 conf]# scp /usr/local/hadoop/zookeeper-3.4.6 root@cluster4:/usr/local/hadoop/
[root@cluster3 data]# scp /usr/local/hadoop/zookeeper-3.4.6 root@cluster5:/usr/local/hadoop/

[root@cluster4 conf]# cd /usr/local/hadoop/zookeeper-3.4.6/data
[root@cluster4 data]# vi myid
4
[root@cluster5 conf]# cd /usr/local/hadoop/zookeeper-3.4.6/data
[root@cluster5 data]# vi myid
5

4、启动

在cluster4、cluster5启动
[root@cluster4 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /usr/local/hadoop/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@cluster5 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /usr/local/hadoop/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

5、查看

[root@cluster5 bin]# ./zkServer.sh status
JMX enabled by default
Using config: /usr/local/hadoop/zookeeper-3.4.6/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
这个可能是脚本问题，暂时不管。
