- 安装zookeeper单机版
1、将最后面附件中的压缩包上传到linux服务器解压：
[root@CLOUD172 opt]# tar –xvf zookeeper-3.4.13.tar.gz
2、进入conf目录，将zoo_sample.cfg启用，重命名为zoo.cfg。
[root@CLOUD172 opt]# cd zookeeper-3.4.13/conf
[root@CLOUD172 conf]#mv zoo_sample.cfg zoo.cfg
3、打开zoo.cfg，修改下面两处配置：
dataDir=/opt/zookeeper-3.4.13/data #数据存储的目录
clientPort=2181 #服务监听的端口
4、进入bin目录，启动zookeeper服务：
[root@CLOUD172 bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.13/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@CLOUD172 bin]#
如果打印的日志像上面这样，就说明zookeeper启动成功了，则把该机器IP和端口2181在GAIA的zookeeper地址上配置。
5、查看zookeeper运行状态：
[root@CLOUD172 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.13/bin/../conf/zoo.cfg
Mode: standalone
[root@CLOUD172 bin]#
6、停止zookeeper运行状态：
[root@CLOUD172 bin]# ./zkServer.sh stop
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.13/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
You have mail in /var/spool/mail/root
[root@CLOUD172 bin]#
7、连接到zookeeper查看数据
[root@CLOUD172 bin]# ./zkCli.sh -server 10.10.1.33:2181

- 安装集群的zookeeper，同机部署两个实例。
1、创建两个目录server1和server2，分别存放两个实例：
[root@CLOUD172 zookeeper]# ll
总用量 8
drwxr-xr-x. 3 root root 4096 2月 18 14:17 server1
drwxr-xr-x. 3 root root 4096 2月 18 14:20 server2
[root@CLOUD172 zookeeper]#
2、进入conf目录，将zoo_sample.cfg启用，重命名为zoo.cfg
[root@CLOUD172 zookeeper]# cd server1/zookeeper-3.4.13/conf/
[root@CLOUD172 conf]# mv zoo_sample.cfg zoo.cfg
[root@CLOUD172 zookeeper]# cd server2/zookeeper-3.4.13/conf/
[root@CLOUD172 conf]# mv zoo_sample.cfg zoo.cfg
3、打开zoo.cfg进行集群配置：
（1）Server1的配置如下：
dataDir=../data #数据存储的目录
clientPort=2181 #服务监听的端口
server.1=10.10.1.33:2888:3888 #实例1交互实例2时占用的端口
server.2=10.10.1.33:2889:3889 #实例2交互实例1时占用的端口
（2）Server2的配置如下：
dataDir=../data
clientPort=2181
server.1=10.10.1.33:2888:3888
server.2=10.10.1.33:2889:3889
server.A=B:C:D中的A是一个数字,表示这个是第几号服务器,B是这个服务器的IP地址，C第一个端口用来集群成员的信息交换,表示这个服务器与集群中的leader服务器交换信息的端口，D是在leader挂掉时专门用来进行选举leader所用的端口。
4、创建serverId标识：
（1）进入server1和bin同级的文件夹，创建data目录，进入data目录，创建myid文件，文件内容输入“1”：
[root@CLOUD172 zookeeper-3.4.13]# pwd
/opt/zookeeper/server1/zookeeper-3.4.13
[root@CLOUD172 zookeeper-3.4.13]# mkdir data
[root@CLOUD172 zookeeper-3.4.13]# cd data
[root@CLOUD172 data]# touch myid
[root@CLOUD172 data]# echo "1" > myid
[root@CLOUD172 data]# more myid
1
[root@CLOUD172 data]#
（2）同理配置server2的myid：
[root@CLOUD172 zookeeper-3.4.13]# pwd
/opt/zookeeper/server2/zookeeper-3.4.13
[root@CLOUD172 zookeeper-3.4.13]# mkdir data
[root@CLOUD172 zookeeper-3.4.13]# cd data
[root@CLOUD172 data]# touch myid
[root@CLOUD172 data]# echo "2" > myid
[root@CLOUD172 data]# more myid
1
[root@CLOUD172 data]#
5、分别进入bin目录启动两个实例，查看两个实例的状态，发现一主一从：
[root@CLOUD172 bin]# pwd
/opt/zookeeper/server1/zookeeper-3.4.13/bin
[root@CLOUD172 bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/server1/zookeeper-3.4.13/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@CLOUD172 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/server1/zookeeper-3.4.13/bin/../conf/zoo.cfg
Mode: follower
You have mail in /var/spool/mail/root
[root@CLOUD172 bin]#
[root@CLOUD172 bin]# pwd
/opt/zookeeper/server2/zookeeper-3.4.13/bin
[root@CLOUD172 bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/server2/zookeeper-3.4.13/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
You have mail in /var/spool/mail/root
[root@CLOUD172 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/server2/zookeeper-3.4.13/bin/../conf/zoo.cfg
Mode: leader
[root@CLOUD172 bin]#
6、Zookeeper其他操作同单机版。
