# 解压缩zookeeper
tar -zxvf /home/hadoop/apache-zookeeper-3.8.2-bin.tar.gz -C /export/server/

# 创建超链接zookeeper
ln -s /export/server/apache-zookeeper-3.8.2-bin/ /export/server/zookeeper

# 移动并且重命名为zoo.cfg
mv /export/server/zookeeper/conf/zoo_sample.cfg /export/server/zookeeper/conf/zoo.cfg

# 编辑zoo.cfg

# 编辑myid文件
vim /export/server/zookeeper/zkData/myid
# node1为1，node2为2，node3为3
1/2/3

# root权限下，修改配置文件
vim /etc/profile

# ZOOKEEPER 文件位置
export ZOOKEEPER_HOME=/export/server/zookeeper
export PATH=$PATH:$ZOOKEEPER_HOME/bin

# 使配置文件生效
source /etc/profile

# 编辑zk脚本，一键启动三个node的zookeeper
vim /usr/local/bin/zk
