1、创建 ~/DevToolKit 文件夹：
2、进入到 /DevToolKit 目录中：
cd ~/DevToolKit/
3、下载 zookeeper-3.4.10.tar.gz：
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
4、解压缩 zookeeper-3.4.10.tar.gz：
tar -zxvf zookeeper-3.4.10.tar.gz
5、进入到 /home/jiangyi/DevToolKit/zookeeper-3.4.10/conf 目录中：
cd zookeeper-3.4.10/conf/
6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：
cp zoo_sample.cfg zoo.cfg
7、用 vim 打开 zoo.cfg 文件并修改其内容为如下：
# The number of milliseconds of each tick
# zookeeper 定义的基准时间间隔，单位：毫秒
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.
# do not use /tmp for storage, /tmp here is just
# example sakes.
# dataDir=/tmp/zookeeper
# 数据文件夹
dataDir=/home/jiangyi/DevToolKit/zookeeper-3.4.10/data
# 日志文件夹
dataLogDir=/home/jiangyi/DevToolKit/zookeeper-3.4.10/logs
# the port at which the clients will connect
# 客户端访问 zookeeper 的端口号
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
#http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
8、保存并关闭 zoo.cfg 文件:
9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/bin 目录中：
cd ../bin/
10、用 vim 打开 /etc/ 目录下的配置文件 profile：
vim /etc/profile
并在其尾部追加如下内容：
export ZOOKEEPER_HOME=/home/jiangyi/DevToolKit/zookeeper-3.4.10/
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH
11、使 /etc/ 目录下的 profile 文件即可生效：
source /etc/profile
12、启动 zookeeper 服务：
zkServer.sh start
13、查询 zookeeper 状态：
zkServer.sh status
14、关闭 zookeeper 服务：
zkServer.sh stop
15、重启 zookeeper 服务：
zkServer.sh restart
16. 切换到root用户，设置防火墙，ip屏蔽取消
firewall-cmd --permanent --add-port=2181/tcp
firewall-cmd --permanent --add-port=20880/tcp
firewall-cmd --permanent --add-port=20881/tcp
firewall-cmd --permanent --add-port=29060/tcp
firewall-cmd --reload
systemctl restart firewalld.service
