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
[plain] view
plain copy
print?
[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
[html] view
plain copy
print?
[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
[plain] view
plain copy
print?
[root@localhost deploy]# cd /opt/deploy/zookeeper-3.3.6/conf
四、拷贝zoo_samle.cfg为zoo.cfg
[plain] view
plain copy
print?
[root@localhost conf]# cp zoo_sample.cfg zoo.cfg
五、编辑zoo.cfg文件
[plain] view
plain copy
print?
[root@localhost conf]# vi zoo.cfg
修改为:
[html] view
plain copy
print?
# 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
[plain] view
plain copy
print?
[root@localhost conf]# export ZOOKEEPER_INSTALL=/opt/deploy/zookeeper-3.3.6
[root@localhost conf]# export PATH=$PATH:$ZOOKEEPER_INSTALL/bin
七、启动
[plain] view
plain copy
print?
[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
[plain] view
plain copy
print?
[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

[root@localhost conf]# vi zoo.cfg
修改为:
[html] view
plain copy

# 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

# 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
[plain] view
plain copy
print?
[root@localhost conf]# export ZOOKEEPER_INSTALL=/opt/deploy/zookeeper-3.3.6
[root@localhost conf]# export PATH=$PATH:$ZOOKEEPER_INSTALL/bin
七、启动
[plain] view
plain copy
print?
[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]#

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

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
