Zookeeper安装部署

一、下载zookeeper安装文件

[[email protected] ~]# wget http://www.apache.org/dist//zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz

[[email protected] ~]# tar -zxvf zookeeper-3.3.6.tar.gz

[[email protected] ~]# cp -r zookeeper-3.3.6 /usr/local/

[[email protected] ~]# cd /usr/local/

[[email protected] local]# chown -R hadoop:hadoop zookeeper-3.3.6/

二、修改配置文件

[[email protected] local]# cd zookeeper-3.3.6/conf/

[[email protected] conf]# cp zoo_sample.cfg zoo.cfg

[[email protected] conf]# vim zoo.cfg

# 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=/tmp/zookeeper

# the port at which the clients will connect

clientPort=2181

#server.A=B：C：D：其中 A 是一个数字，表示这个是第几号服务器；B 是这个服务器的 ip 地址；C 表示的是这个服务器与集群中的 Leader 服务器交换信息的端口；D 表示的是万一集群中的 #Leader 服务器挂了，需要一个端口来重新进行选举，选出一个新的 Leader，而这个端口就是用来执行选举时服务器相互通信的端口。如果是伪集群的配置方式，由于 B 都是一样，所以不同的 #Zookeeper 实例通信端口号不能一样，所以要给它们分配不同的端口号。

server.1=192.168.101.230:2555:3555

server.2=192.168.101.231:2555:3555

server.2=192.168.101.232:2555:3555

三、修改权限，建立data目录并赋予权限

[[email protected] local]# scp -r zookeeper-3.3.6/ [email protected]:/usr/local/

[[email protected] local]# scp -r zookeeper-3.3.6/ [email protected]:/usr/local/

[[email protected] local]# ssh slave1

[email protected]‘s password:

Last login: Tue Apr  5 16:57:35 2016 from master

[[email protected] ~]# cd /usr/local/

[[email protected] local]# chown -R hadoop:hadoop zookeeper-3.3.6/

[[email protected] local]# su hadoop

[[email protected] local]$ cd zookeeper-3.3.6/

[[email protected] zookeeper-3.3.6]$ cd conf/

[[email protected] conf]$ mkdir /tmp/zookeeper

[[email protected] conf]$ cd /tmp/zookeeper/

[[email protected] zookeeper]$ mkdir data

[[email protected] zookeeper]$ vim myid

1

同理，slave1上myid为2，在slave2上输入myid=3

修改权限，data目录修改属主和属组为hadoop，master、slave1和slave2上都得修改权限

[[email protected] ~]# chown -R hadoop:hadoop /tmp/zookeeper/

四、启动zookeeper

[[email protected] bin]$ ./zkServer.sh start

JMX enabled by default

Using config: /usr/local/zookeeper-3.3.6/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED
