zookeeper3.5.5 集群安装

机器三台做集群
其实每台机器操作一致。

1.下载zookeeper
http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.5/apache-zookeeper-3.5.5-bin.tar.gz

2.解压zookeeper
tar xvf apache-zookeeper-3.5.5-bin.tar.gz

$ cd apache-zookeeper-3.5.5-bin/
$ cd conf/
$ cp zoo_sample.cfg zoo.cfg 
$ cat zoo.cfg 
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/apache-zookeeper-3.5.5-bin/tmp
clientPort=2181
server.1=10.190.210.177:2888:3888
server.2=10.190.210.191:2888:3888
server.3=10.190.210.192:2888:3888

4.每台机器myid要不同

$ mkdir  /usr/local/apache-zookeeper-3.5.5-bin/tmp
$ echo 1 >  /usr/local/apache-zookeeper-3.5.5-bin/tmp/myid ##第一台机器
$ echo 2 >  /usr/local/apache-zookeeper-3.5.5-bin/tmp/myid ##第二台机器
$ echo 3 >  /usr/local/apache-zookeeper-3.5.5-bin/tmp/myid ##第三台机器

5 查看状态

$ ../bin/zkServer.sh  restart
$  ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/soft/zookeeper-3.5.5/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: follower

6 执行客户端创建
$ ./zkCli.sh
[zk: localhost:2181(CONNECTED) 0] ls /
[zookeeper]
[zk: localhost:2181(CONNECTED) 1] create /zoo hello
Created /zoo
[zk: localhost:2181(CONNECTED) 2] ls /
[zoo, zookeeper]
再在其他服务器上使用zkCli.sh
可以查看到刚刚的操作数据
