安装步骤

第一步：上传zookeeper-3.4.8.tar.gz并解压

1. #usr/local/ 下创建zookeeper文件夹[root@localhost /]# mkdir /usr/local/zookeeper 2. #解压tar: tar -zxvf zookeeper-3.4.8.tar.gz  3. #usr/local/zookeeper/下复制三份解压后的文件：   [root@localhost donggua]# cp -r zookeeper-3.4.8 /usr/local/zookeeper/zookeeper01   [root@localhost donggua]# cp -r zookeeper-3.4.8 /usr/local/zookeeper/zookeeper02   [root@localhost donggua]# cp -r zookeeper-3.4.8 /usr/local/zookeeper/zookeeper03

第二步：配置zookeeper

2.1 在zookeeper01中创建一个 data的文件夹

[root@localhost zookeeper01]# mkdir data

2.2 在data中创建一个myid的文件

[root@localhost zookeeper01]# cd data/[root@localhost data]# ls[root@localhost data]# [root@localhost data]# [root@localhost data]# touch myid

2.3 在myid文件的内容为1

[root@localhost data]# vim myid #写入内容为1

2.4 zookeeper01、zookeeper03依次类推

zookeeper02:

[root@localhost zookeeper02]# mkdir data[root@localhost zookeeper02]# cd data/[root@localhost data]# touch myid[root@localhost data]# echo 2 > myid[root@localhost data]# vim myid

zookeeper03:

[root@localhost zookeeper03]# mkdir data[root@localhost zookeeper03]# cd data/[root@localhost data]# touch myid[root@localhost data]# echo 3 > myid

2.5 修改配置文件

2.5.1修改zookeeper01的配置文件：

[root@localhost /]# cd /usr/local/zookeeper/zookeeper01/[root@localhost zookeeper01]# lsbin          data             lib                   recipes                  zookeeper-3.4.8.jar.sha1build.xml    dist-maven       LICENSE.txt           srcCHANGES.txt  docs             NOTICE.txt            zookeeper-3.4.8.jarconf         ivysettings.xml  README_packaging.txt  zookeeper-3.4.8.jar.asccontrib      ivy.xml          README.txt            zookeeper-3.4.8.jar.md5[root@localhost zookeeper01]# cd conf/  #进入zookeeper01的配置文件路径下[root@localhost conf]# lltotal 12-rw-r--r--. 1 root root  535 Feb 25 09:21 configuration.xsl-rw-r--r--. 1 root root 2161 Feb 25 09:21 log4j.properties-rw-r--r--. 1 root root  922 Feb 25 09:21 zoo_sample.cfg[root@localhost conf]# cp zoo_sample.cfg  zoo.cfg #zoo_sample.cfg 复制一份 命名为：zoo.cfg[root@localhost conf]# lltotal 16-rw-r--r--. 1 root root  535 Feb 25 09:21 configuration.xsl-rw-r--r--. 1 root root 2161 Feb 25 09:21 log4j.properties-rw-r--r--. 1 root root  922 Feb 25 10:01 zoo.cfg-rw-r--r--. 1 root root  922 Feb 25 09:21 zoo_sample.cfg[root@localhost conf]# vim zoo.cfgdataDir=/usr/local/zookeeper/zookeeper01/data/ #配置zookeeper01的data路径clientPort=2181 #配置端口号server.1=192.168.31.103:2881:3881 #配置三个zookeeper节点，注意端口号不能重复server.2=192.168.31.103:2882:3882server.3=192.168.31.103:2883:3883

2.5.2修改zookeeper02的配置文件：

同2.5.1 复制zoo_sample.cfg 一份命名为：zoo.cfg
编辑如下内容：

dataDir=/usr/local/zookeeper/zookeeper02/data/ #配置zookeeper02的data路径clientPort=2182 #配置端口号server.1=192.168.31.103:2881:3881 #配置三个zookeeper节点，注意端口号不能重复server.2=192.168.31.103:2882:3882server.3=192.168.31.103:2883:3883

2.5.3修改zookeeper03的配置文件：

同2.5.1 复制zoo_sample.cfg 一份命名为：zoo.cfg
编辑如下内容：

dataDir=/usr/local/zookeeper/zookeeper03/data/ #配置zookeeper03的data路径clientPort=2183 #配置端口号server.1=192.168.31.103:2881:3881 #配置三个zookeeper节点，注意端口号不能重复server.2=192.168.31.103:2882:3882server.3=192.168.31.103:2883:3883

2.6 启动zookeeper集群

[root@localhost zookeeper]# cd zookeeper01/bin/[root@localhost bin]# ./zkServer.sh start #stuas 查看状态， stop 关闭[root@localhost zookeeper]# cd zookeeper02/bin/[root@localhost bin]# ./zkServer.sh start #stuas 查看状态， stop 关闭[root@localhost zookeeper]# cd zookeeper03/bin/[root@localhost bin]# ./zkServer.sh start #stuas 查看状态， stop 关闭

第三步 zookeeper启动脚本编写：

[root@localhost zookeeper]# vim zookeeper-start.sh #!/bin/shcd zookeeper01/bin/./zkServer.sh startcd ../..cd zookeeper02/bin/./zkServer.sh startcd ../..cd zookeeper03/bin/./zkServer.sh startcd ../..

出现错误的解决：

查看状态时出现：

[root@localhost bin]# ./zkServer.sh statusZooKeeper JMX enabled by defaultUsing config: /usr/local/zookeeper/zookeeper01/bin/../conf/zoo.cfgError contacting service. It is probably not running.

解决：
1. 是否关闭防火墙或者端口是否开放
2. data/myid 的内容是否和当前节点是否匹配： zookeeper01-> 1,
zookeeper02 ->2, zookeeper03->3
3.conf/zoo.cfg中，端口号是否匹配。
