What is ZooKeeper?

ZooKeeper是用于维护配置信息，命名，提供分布式同步和提供组服务的集中式服务。 所有这些类型的服务都以某种形式被分布式应用程序使用。 每次实施它们时，都会进行很多工作来修复不可避免的错误和竞争条件。 由于难以实现这类服务，因此应用程序最初通常会跳过它们，这会使它们在存在更改的情况下变得脆弱，并且难以管理。 即使部署正确，这些服务的不同实现也会导致管理复杂。

集群

环境：单台宿主机（192.168.192.128），启动三个zookeeper容器。

这里涉及一个问题，就是Docker容器之间通信的问题，这个很重要！

[root@recall-gpu-01 ~]# docker network ls
NETWORK ID     NAME       DRIVER    SCOPE
cf4c40eade1c   bridge     bridge    local
c8279f8d143e   host       host      local
e9fcc824e3eb   minikube   bridge    local
058a268a86b9   none       null      local

Docker有三种网络模式，bridge、host、none，在你创建容器的时候，不指定–network默认是bridge。

bridge：为每一个容器分配IP，并将容器连接到一个docker0虚拟网桥，通过docker0网桥与宿主机通信。也就是说，此模式下，你不能用宿主机的IP+容器映射端口来进行Docker容器之间的通信。

host：容器不会虚拟自己的网卡，配置自己的IP，而是使用宿主机的IP和端口。这样一来，Docker容器之间的通信就可以用宿主机的IP+容器映射端口

none：无网络。

=====================================================

先在本地创建目录：

                    "Gateway": "10.11.11.1"

然后我们修改一下zookeeper容器的创建命令。

\1. 由于2888 、3888 不需要暴露，就不映射了；

\2. 指定自己的网络，并指定IP；

\3. 每个容器之间环境是隔离的，所以容器内所用的端口一样：2181/2888/3888

[root@localhost admin]# mkdir -p /usr/local/zookeeper-cluster/node5
[root@localhost admin]# mkdir -p /usr/local/zookeeper-cluster/node6

新建任意目录，然后在里面新建一个文件
