笔记:zookeeper Hello World
下载zookeeper-3.4.6 , 试用了一下
standlone
启动
./bin/zkServer.sh start
注: Usage: ./bin/zkServer.sh {start|start-foreground|stop|restart|status|upgrade|print-cmd}_
用cli工具就可以操作了
./bin/zkCli.sh -server 127.0.0.1:2181
[zk: 127.0.0.1:2181(CONNECTED) 0] help
ZooKeeper -server host:port cmd args
connect host:port
get path [watch]
ls path [watch]
set path data [version]
rmr path
delquota [-n|-b] path
quit
printwatches on|off
create [-s] [-e] path data acl
stat path [watch]
close
ls2 path [watch]
history
listquota path
setAcl path acl
getAcl path
sync path
redo cmdno
addauth scheme auth
delete path [version]
setquota -n|-b val path
cluster
改 conf/zoo.cfg 文件,添加下面两行 (我用173和207两台机器组建 cluster)
server.1=10.15.4.173:2888:3888
server.2=10.15.4.207:2888:3888
创建myid文件
在173上 echo 1 > /tmp/zookeeper/myid
在207上 echo 2 > /tmp/zookeeper/myid
在两台机器都启动 (./bin/zkServer.sh start)
173上查看
$ ./bin/zkServer.sh status
JMX enabled by default
Using config: /home/payne/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: leader
207上查看
$ ./bin/zkServer.sh status
JMX enabled by default
Using config: /home/payne/zookeeper-3.4.6/bin/../conf/zoo.cfg
Mode: follower
注:没有 myid, 或者只启动一台,zkCli.sh 连接不上
