ZooKeeper安装配置
ZooKeeper的安装及配置 Mac
一，ZooKeeper安装及配置
1.打开ZooKeeper官网：http://zookeeper.apache.org/
2.点击下载，点击存档（所有版本的信息都在这个目录下）
3.选择所需下载稳定版本 zookeeper-3.4.12.tar.gz
4.下载 zookeeper-3.4.12.tar.gz
5.解压命令：tar -zxvf重命名命令：mv zookeeper-3.4.12 zookeeper
6.移动到/ usr / local文件目录下，命令：
sudo mv zookeeper / usr / local
7.配置环境变量：vim / etc / profile
二，zookeeper 的主要目录结构
LICENSE.txt ivy.xml
NOTICE.txt ivysettings.xml
README.md lib
README_packaging.txt recipes
bin src
build.xml zookeeper-3.4.11.jar
conf zookeeper-3.4.11.jar.asc
contrib zookeeper-3.4.11.jar.md5
dist-maven zookeeper-3.4.11.jar.sha1
docs
bin:一些运行命令
conf：配置文件，zk.cfg需要配置
contrib：附加功能
dist-maven:mvn编译目录
docs:帮助文档
lib：依赖包
recipes:Demo代码
三，配置zoo.cfg
1.官网有如下描述
2.复制配置文件：cp zoo_sample.cfg zoo.cfg
3.客户化配置文件：vim zoo.cfg
tickTime:session超时时间配置
initLimit：集群节点同步时间
syncLimit:集群主节点与从节点发送消息的请求和应答时间
dataDir:默认目录
dataLogDir：日志目录
clientPort:：端口号
创建目录DATADIR和dataLogDir
4.启动zookeeper，到zookeeper bin目录下执行./zkServer.sh start进行启动
四. 连接测试：
1. Cli连接:
> cd zookeeper-3.4.12/bin //切换到 bin目录
> ./zkCli.sh -server 127.0.0.1:2181
[zk: 127.0.0.1:2181(CONNECTED) 0] help //输入help命令
ZooKeeper -server host:port cmd args
stat path [watch]
set path data [version]
ls path [watch]
delquota [-n|-b] path
ls2 path [watch]
setAcl path acl
setquota -n|-b val path
history
redo cmdno
printwatches on|off
delete path [version]
sync path
listquota path
rmr path
get path [watch]
create [-s] [-e] path data acl
addauth scheme auth
quit
getAcl path
close
connect host:port

[zk: 127.0.0.1:2181(CONNECTED) 8] delete /zk_test
[zk: 127.0.0.1:2181(CONNECTED) 9] ls
[zk: 127.0.0.1:2181(CONNECTED) 10] ls /
[zookeeper]
2. 停止Server
> ./zkServer.sh stop //停止后，如果CLi没有关闭，将报错
ZooKeeper JMX enabled by default
Using config: zookeeper-3.4.12/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
3. 配置文件说明
文件名可以任意，不是非得改为zoo.cfg
tickTime: zookeeper中使用的基本时间单位, 毫秒
dataDir: 内存数据快照的保存目录；如果没有自定义Log也使用该目录
clientPort: 监听Cli连接的端口号
