# 安装zookeeper程序包

cd   /opt/

mkdir /usr/local/zookeeper

#注意要bin版本

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.6.2/apache-zookeeper-3.6.2-bin.tar.gz

tar -xzvf  apache-zookeeper-3.6.2-bin.tar.gz

mv apache-zookeeper-3.6.2-bin  zookeeper-3.6.2

/bin/cp zookeeper-3.6.2/* /usr/local/zookeeper/  -a

# 修改配置文件

mkdir /usr/local/zookeeper/data/

mkdir /usr/local/zookeeper/logs/

touch /usr/local/zookeeper/data/myid

echo 1 > /usr/local/zookeeper/data/myid

mv /usr/local/zookeeper/conf/zoo_sample.cfg /usr/local/zookeeper/conf/zoo.cfg

# vi  /etc/profile

export ZOOKEEPER_HOME=/usr/local/zookeeper
PATH=$ZOOKEEPER_HOME/bin:$PATH

source /etc/profile

 vi  /usr/local/zookeeper/conf/zoo.cfg

修改并追加以下内容：
clientPort=2181
#zookeeper02节点的这个位置为2182，zookeeper03节点的这个位置为2183
dataDir=/usr/local/zookeeper/data    
# zookeeper02和zookeeper03节点要修改成响应的目录。
dataLogDir=/usr/local/zookeeper/logs 
# zookeeper02和zookeeper03节点要修改成响应的目录。
server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
按照上面的修改继续修改zookeeper02和zookeeper03的配置项。
