Linux下安装Zookeeper

Zookeeper是一个协调服务,可以用它来作为配置维护、名字服务、分布式部署;

下面,我来分享一下在Linux下安装Zookeeper的整个步骤,让大家少走弯路。

一、Zookeeper下载

[root@localhost 下载]# wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz  
--2016-01-15 23:15:57--  http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz  
正在解析主机 mirror.bit.edu.cn (mirror.bit.edu.cn)... 114.247.56.117  
正在连接 mirror.bit.edu.cn (mirror.bit.edu.cn)|114.247.56.117|:80... 已连接。  
已发出 HTTP 请求,正在等待回应... 200 OK  
长度:11833706 (11M) [application/octet-stream]  
正在保存至: “zookeeper-3.3.6.tar.gz”  
100%[======================================================================>] 11,833,706   171KB/s 用时 68s      
2016-01-15 23:17:07 (170 KB/s) - 已保存 “zookeeper-3.3.6.tar.gz” [11833706/11833706])  

 

二、解压

[root@localhost deploy]# tar -zxvf /home/lk/下载/zookeeper-3.3.6.tar.gz   
解压完之后,会在deploy文件夹下面得到一个zookeeper-3.3.6的文件夹

 

三、进入到conf目录

[root@localhost deploy]# cd /opt/deploy/zookeeper-3.3.6/conf  

 

四、拷贝zoo_samle.cfg为zoo.cfg

[root@localhost conf]# cp zoo_sample.cfg zoo.cfg  
 

五、编辑zoo.cfg文件

[root@localhost conf]# vi zoo.cfg 

修改为:

# The number of milliseconds of each tick
tickTime=2000  
# The number of ticks that the initial  
# synchronization phase can take  
initLimit=10  
# The number of ticks that can pass between  
# sending a request and getting an acknowledgement  
syncLimit=5  
# the directory where the snapshot is stored.  
dataDir=/usr/zookeeper  
dataLogDir=/usr/zookeeper/log  
# the port at which the clients will connect  
clientPort=2181  
server.1=192.168.32.129:2888:3888  

 六、设置环境变量

[root@localhost conf]# export ZOOKEEPER_INSTALL=/opt/deploy/zookeeper-3.3.6
[root@localhost conf]# export PATH=$PATH:$ZOOKEEPER_INSTALL/bin 

七、启动

[root@localhost bin]# ./zkServer.sh start  
JMX enabled by default  
Using config: /opt/deploy/zookeeper-3.3.6/bin/../conf/zoo.cfg  
Starting zookeeper ... STARTED  
[root@localhost bin]#   

八、测试zookeeper

[root@localhost bin]# ./zkCli.sh -server 192.168.32.129:2181  

如果是本地连接,那么不需要 -server 192.168.32.129:2181,默认是本地

注意:如果出现拒绝连接,请检查如下:

1、防火墙是否关闭  systemctl stop firewalld

2、需要将192.168.32.129 映射到本地 /etc/hosts文件中,否则无法连接
