zookeeper伪分布集群配置

1、上传tar文件zookeeper-3.4.12.tar.gz

2、解压zookeeper-3.4.12.tar.gz

[root@localhost zookeeper]# tar -zxvf zookeeper-3.4..tar.gz 

3、重命名为zk01

[root@localhost zookeeper]# mv zookeeper-3.4. zk01

4、配置zoo.cfg

tickTime=
initLimit=
syncLimit=
dataDir=/mirana/software/zookeeper/zk01/data
dataLogDir=/mirana/software/zookeeper/zk01/datalog

clientPort=

server.=127.0.0.1::
server.=127.0.0.1::
server.=127.0.0.1::

5、在添加myid文件，这里的myid里面的内容对应zoo.cfg中的server.x的x，所以这里写1

[root@localhost zookeeper]# cd zk01
[root@localhost zk01]# mkdir data
[root@localhost zk01]# mkdir data && cd data
[root@localhost data]# echo 1 > myid

6、复制zk01到zk02和zk03

[root@localhost zookeeper]# cp zk01 zk02 -R
[root@localhost zookeeper]# cp zk01 zk03 -R

7、修改zk02的zoo.cfg和myid如下：

[root@localhost zookeeper]# cd zk02/
[root@localhost zk02]# cat conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/mirana/software/zookeeper/zk02/data
dataLogDir=/mirana/software/zookeeper/zk02/datalog

clientPort=2182

server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890

[root@localhost zk02]# cat data/myid
2

8、修改zk03的zoo.cfg和myid如下：

[root@localhost zookeeper]# cd zk03/
[root@localhost zk03]# cat conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/mirana/software/zookeeper/zk03/data
dataLogDir=/mirana/software/zookeeper/zk03/datalog

clientPort=2183

server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890

[root@localhost zk03]# cat data/myid
3

9、分别启动三个zookeeper

[root@localhost zookeeper]# zk01/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /mirana/software/zookeeper/zk01/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost zookeeper]# zk02/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /mirana/software/zookeeper/zk02/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost zookeeper]# zk03/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /mirana/software/zookeeper/zk03/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

10、查看三个zookeeper的状态

[root@localhost zookeeper]# zk01/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /mirana/software/zookeeper/zk01/bin/../conf/zoo.cfg
Mode: follower
[root@localhost zookeeper]# zk02/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /mirana/software/zookeeper/zk02/bin/../conf/zoo.cfg
Mode: leader
[root@localhost zookeeper]# zk03/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /mirana/software/zookeeper/zk03/bin/../conf/zoo.cfg
Mode: follower
