zookeeper分布式部署方案

版本：http://apache.fayea.com/zookeeper/zookeeper-3.4.8/

环境：debian 7/8

说明：最低配置3台

步骤：
1.下载zookeeper-3.4.8并解压缩到合适的位置（本文地址为：/var/local/）

2.配置zookeeper-3.4.8
2.1单机伪分布式部署
注意：部署在同一台电脑时，特别注意不能共用相同的端口号，包括clientPort，server.1-3的端口号

(1)
zookeeper-3.4.8-1
位置：/var/local/zookeeper-3.4.8-1

sudo mkdir -p /var/local/zookeeper-3.4.8-1/data
sudo mkdir -p /var/local/zookeeper-3.4.8-1/data/log
echo 1 > /var/local/zookeeper-3.4.8-1/data/myid
(若无权限：sudo vi /var/local/zookeeper-3.4.8-1/data/myid {1}，即值为1)
cd /var/local/zookeeper-3.4.8-1/conf/ &&sudo mv zoo_sample.cfg zoo.cfg &&sudo vi zoo.cfg
{
clientPort=2181
dataDir=/var/local/zookeeper-3.4.8-1/data
dataLogDir=/var/local/zookeeper-3.4.8-1/data/log
autopurge.snapRetainCount=3
autopurge.purgeInterval=1

server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
}

(2)
zookeeper-3.4.8-2
位置：/var/local/zookeeper-3.4.8-2

sudo cp -p /var/local/zookeeper-3.4.8-1 /var/local/zookeeper-3.4.8-2
sudo vi /var/local/zookeeper-3.4.8-2/data/myid {2}
sudo vi /var/local/zookeeper-3.4.8-2/conf/zoo.cfg
{
clientPort=2182
dataDir=/var/local/zookeeper-3.4.8-2/data
dataLogDir=/var/local/zookeeper-3.4.8-2/data/log
autopurge.snapRetainCount=3
autopurge.purgeInterval=1

server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
}

(3)
zookeeper-3.4.8-3
位置：/var/local/zookeeper-3.4.8-3
sudo cp -p /var/local/zookeeper-3.4.8-1 /var/local/zookeeper-3.4.8-3
sudo vi /var/local/zookeeper-3.4.8-3/data/myid {3}
sudo vi /var/local/zookeeper-3.4.8-3/conf/zoo.cfg
{
clientPort=2183
dataDir=/var/local/zookeeper-3.4.8-3/data
dataLogDir=/var/local/zookeeper-3.4.8-3/data/log
autopurge.snapRetainCount=3
autopurge.purgeInterval=1

server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
}

2.2分布式部署
(1)
zookeeper-3.4.8
位置：node1:/var/local/zookeeper-3.4.8

sudo mkdir -p /var/local/zookeeper-3.4.8/data
sudo mkdir -p /var/local/zookeeper-3.4.8/data/log
echo 1 > /var/local/zookeeper-3.4.8/data/myid
(若无权限：sudo vi /var/local/zookeeper-3.4.8/data/myid {1}，即值为1)
cd /var/local/zookeeper-3.4.8/conf/ &&sudo mv zoo_sample.cfg zoo.cfg &&sudo vi zoo.cfg
{
dataDir=/var/local/zookeeper-3.4.8/data
dataLogDir=/var/local/zookeeper-3.4.8/data/log
autopurge.snapRetainCount=3
autopurge.purgeInterval=1

server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888
}

(2)
位置：node2:/var/local/zookeeper-3.4.8
scp -r node1:/var/local/zookeeper-3.4.8 node2:/var/local/zookeeper-3.4.8
echo 1 > /var/local/zookeeper-3.4.8/data/myid
(若无权限：sudo vi /var/local/zookeeper-3.4.8/data/myid {2}，即值为2)

(3)
位置：node3:/var/local/zookeeper-3.4.8
scp -r node1:/var/local/zookeeper-3.4.8 node2:/var/local/zookeeper-3.4.8
echo 1 > /var/local/zookeeper-3.4.8/data/myid
(若无权限：sudo vi /var/local/zookeeper-3.4.8/data/myid {3}，即值为3)

3.启动及监控
分别启动每台zookeeper即可
3.1单机伪分布式部署
启动：
sudo /var/local/zookeeper-3.4.8-1/bin/zkServer.sh start
sudo /var/local/zookeeper-3.4.8-2/bin/zkServer.sh start
sudo /var/local/zookeeper-3.4.8-3/bin/zkServer.sh start
查看状态：
sudo /var/local/zookeeper-3.4.8-1/bin/zkServer.sh status
sudo /var/local/zookeeper-3.4.8-2/bin/zkServer.sh status
sudo /var/local/zookeeper-3.4.8-3/bin/zkServer.sh status
