zookeeper安装

1.解压

[root@hadoop001 /]# cd /usr/
[root@hadoop001 usr]# ls
bin  etc  games  hadoop330  include  java  lib  lib64  libexec  local  sbin  share  src  tmp
[root@hadoop001 usr]# mkdir zookeeper370
[root@hadoop001 usr]# ls
bin  etc  games  hadoop330  include  java  lib  lib64  libexec  local  sbin  share  src  tmp  zookeeper370
[root@hadoop001 usr]# cd ..
[root@hadoop001 /]# cd /opt/
[root@hadoop001 opt]# ls
apache-hive-3.1.2-bin.tar.gz       hbase-2.4.2-bin.tar.gz  VMwareTools-10.3.21-14772444.tar.gz
apache-zookeeper-3.7.0-bin.tar.gz  rh                      vmware-tools-distrib
[root@hadoop001 opt]# tar -zxvf apache-zookeeper-3.7.0-bin.tar.gz -C /usr/zookeeper370

其他两台操作一样

2.如果不是root需要修改hadoop主机的权限

[root@hadoop001 opt]# sudo chown -R hadoop:hadoop /usr/zookeeper370/apache-zookeeper-3.7.0-bin/

3.配置服务器编号

[root@hadoop001 apache-zookeeper-3.7.0-bin]# mkdir -p zkData
[root@hadoop001 apache-zookeeper-3.7.0-bin]# ls
bin  conf  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.md  zkData
[root@hadoop001 apache-zookeeper-3.7.0-bin]# cd zkData/
[root@hadoop001 zkData]# touch myid
[root@hadoop001 zkData]# vi myid 
[root@hadoop001 zkData]# cat myid 
001

其他两台002,003
[root@hadoop002 apache-zookeeper-3.7.0-bin]# cd zkData/
[root@hadoop002 zkData]# touch myid
[root@hadoop002 zkData]# vi myid 
[root@hadoop002 zkData]# cat myid 
002


[root@hadoop003 apache-zookeeper-3.7.0-bin]# cd zkData/
[root@hadoop003 zkData]# touch myid
[root@hadoop003 zkData]# vi myid 
[root@hadoop003 zkData]# cat myid 
003

添加环境变量

[root@hadoop001 etc]# vi /etc/profile

#zookeeper3.7.0
export ZOOKEEPER_HOME=/usr/zookeeper370/apache-zookeeper-3.7.0-bin
export PATH=$ZOOKEEPER_HOME/bin:$PATH

[root@hadoop001 ~]# source /etc/profile
[root@hadoop001 etc]# 

[root@hadoop001 conf]# scp -r /etc/profile root@hadoop002:/etc/

[root@hadoop002 conf]# source /etc/profile

[root@hadoop001 conf]# scp -r /etc/profile root@hadoop003:/etc/

[root@hadoop003 conf]# source /etc/profile

4.修改配置文件

[root@hadoop001 apache-zookeeper-3.7.0-bin]# cd /usr/zookeeper370/apache-zookeeper-3.7.0-bin/conf/
[root@hadoop001 conf]# ls
configuration.xsl  log4j.properties  zoo_sample.cfg
[root@hadoop001 conf]# cp zoo_sample.cfg zoo.cfg
[root@hadoop001 conf]# vim zoo.cfg
[root@hadoop001 conf]# cat 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=/usr/zookeeper370/apache-zookeeper-3.7.0-bin/zkData
dataLogDir=/usr/zookeeper370/apache-zookeeper-3.7.0-bin/tmp/logs

[root@hadoop001 conf]# 

[root@hadoop001 conf]# cd ..

[root@hadoop001 conf]# scp -r /usr/zookeeper370 root@hadoop002:/usr/
[root@hadoop001 conf]# scp -r /usr/zookeeper370 root@hadoop003:/usr/

[root@hadoop001 hbase-2.4.2]# scp -r /usr/hbase242 root@hadoop003:/usr/

5.集群操作

分别启动Zookeeper

查看状态

[root@hadoop001 apache-zookeeper-3.7.0-bin]# bin/zkServer.sh start
[root@hadoop001 apache-zookeeper-3.7.0-bin]# bin/zkServer.sh status

启动客户端

[root@hadoop001 apache-zookeeper-3.7.0-bin]# bin/zkCli.sh

#或者
[root@hadoop001 apache-zookeeper-3.7.0-bin]# bin/zkCli.sh -server localhost:2181

[zk: localhost:2181(CONNECTED) 0] help
[zk: localhost:2181(CONNECTED) 1] ls /
