一. 原生安装

1. 环境准备

必须要有java8以上版本

2. 下载Zookeeper

https://www.apache.org/dyn/closer.lua/zookeeper/zookeeper-3.5.10/apache-zookeeper-3.5.10.tar.gz

3. 上传Zookeeper到虚拟机

4. 解压缩

当前文件下创建一个目录

 mkdir zookeeper

移动到zookeeper包里面

mv apache-zookeeper-3.5.10.tar.gz /usr/local/src/zookeeper/

解压缩

  cd zookeeper
 tar -zxvf apache-zookeeper-3.5.10.tar.gz

5. 配置

进入

 cd apache-zookeeper-3.5.10/
 cd conf/

原本的zoo_sample.cfg无法使用，需要创建一个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.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/tmp/zookeeper
# the port at which the clients will connect
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

需要改变dataDir 在当前目录创建zkdata目录，存放数据

mkdir zkdata

dataDir改为/usr/local/src/zookeeper/apache-zookeeper-3.5.10/conf/zkdata 重新上传zoo.cfg

6. 启动zookeeper

进入zookeeper的bin

 ./zkServer.sh start

启动成功

[root@192 bin]# ./zkServer.sh start
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/src/zookeeper/apache-zookeeper-3.5.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

查看状态

./zkServer.sh status

关闭

./zkServer.sh stop

2. Docker安装

1. 环境配置

java8以上，docker

2. 安装

查看zookeeper版本

docker search zookeeper

下载最新版本，可以指定版本

docker pull zookeeper:latest

创建挂载数据

mkdir -p /root/docker/zookeeper/data

3. 启动容器

查看zookeeper镜像

docker images

docker run -d -p 2181:2181 -v /root/docker/zookeeper/data:/data/ --name zookeeper --privileged 36c607e7b14d

参数说明

-d # 表示在一直在后台运行容器
-p 2181:2181 # 对端口进行映射，将本地2181端口映射到容器内部的2181端口
--name # 设置创建的容器名称
-v # 将本地目录挂载到容器指定目录；
--privileged  # 镜像id或者镜像名称也可以

4. 查看启动

docker ps

5. 进入容器

docker exec -it 069a2219323c /bin/bash

中间id是容器id

进入bin

cd bin

启动

./zkCli.sh
