Docker 部署zookeeper集群

编程入门行业动态更新时间:2024-10-24 06:29:03

1、docker 查看zookeeper镜像。

docker NAME zookeeper jplock/zookeeper wurstmeister/zookeeper mesoscloud/zookeeper bitnami/zookeeper mbabineau/zookeeper-exhibitor digitalwonderland/zookeeper tobilg/zookeeper-webui confluent/zookeeper debezium/zookeeper 31z4/zookeeper thefactory/zookeeper-exhibitor emccorp/zookeeper engapa/zookeeper paulbrown/zookeeper duffqiu/zookeeper-cli perrykim/zookeeper strimzi/zookeeper josdotso/zookeeper-exporter openshift/zookeeper-346-fedora20 midonet/zookeeper humio/zookeeper-dev dabealu/zookeeper-exporter phenompeople/zookeeper pravega/zookeeper-operator [root@localhost /]#

我们就选取官方版本 alt="Docker 部署zookeeper集群"/>

docker pull zookeeper

2、集群部署zookeeper有两种方式：

直接启动三个容器，运行zookeeper
利用docker-compose 部署

2.1 在这之前我们需要创建一个自己的网络，用于不同容器的通信。这样做是因为Docker网络分为三种网络模式，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。

docker network create --driver bridge --subnet=172.18.0.0/16 --gateway=172.18.0.1 zoonet

然后执行命令：

docker run -d -p 2181:2181 --name zookeeper_node1 --privileged --restart always --network zoonet --ip 172.18.0.2 \
-v /work/zookeeper/node1/volumes/data:/data \
-v /work/zookeeper/node1/volumes/datalog:/datalog \
-v /work/zookeeper/node1/volumes/logs:/logs \
-e ZOO_MY_ID=1 \
-e "ZOO_SERVERS=server.1=172.18.0.2:2888:3888;2181 server.2=172.18.0.3:2888:3888;2181 server.3=172.18.0.4:2888:3888;2181" 6ad6cb039dfadocker run -d -p 2182:2181 --name zookeeper_node2 --privileged --restart always --network zoonet --ip 172.18.0.3 \
-v /work/zookeeper/node2/volumes/data:/data \
-v /work/zookeeper/node2/volumes/datalog:/datalog \
-v /work/zookeeper/node2/volumes/logs:/logs \
-e ZOO_MY_ID=2 \
-e "ZOO_SERVERS=server.1=172.18.0.2:2888:3888;2181 server.2=172.18.0.3:2888:3888;2181 server.3=172.18.0.4:2888:3888;2181" 6ad6cb039dfadocker run -d -p 2183:2181 --name zookeeper_node3 --privileged --restart always --network zoonet --ip 172.18.0.4 \
-v /work/zookeeper/node3/volumes/data:/data \
-v /work/zookeeper/node3/volumes/datalog:/datalog \
-v /work/zookeeper/node3/volumes/logs:/logs \
-e ZOO_MY_ID=3 \
-e "ZOO_SERVERS=server.1=172.18.0.2:2888:3888;2181 server.2=172.18.0.3:2888:3888;2181 server.3=172.18.0.4:2888:3888;2181" 6ad6cb039dfa

2.2 利用docker-compose 部署zookeeper集群

首先安装docker-compose

方式1、
curl -L ".24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose方法2：1、安装python-pipyum -y install epel-releaseyum -y install python-pip2、安装docker-composepip install docker-compose

安装完成之后，创建数据挂载目录：

[root@localhost root]# mkdir /work/zookeeper/node1
[root@localhost root]# mkdir /work/zookeeper/node2
[root@localhost root]# mkdir /work/zookeeper/node3

然后创建docker-compose文件

[root@localhost root]# mkdir DockerComposeFolder
[root@localhost root]# cd DockerComposeFolder/
[root@localhost DockerComposeFolder]# vim docker-compose.yml

写入如下内容：

version: '3.1'services:zoo1:image: zookeeperrestart: alwaysprivileged: truehostname: zoo1ports:- 2181:2181volumes: # 挂载数据- /work/zookeeper/node1/data:/data- /work/zookeeper/node1/datalog:/datalog- /work/zookeeper/node1/conf:/confenvironment:ZOO_MY_ID: 1ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181networks:default:ipv4_address: 172.18.0.14zoo2:image: zookeeperrestart: alwaysprivileged: truehostname: zoo2ports:- 2182:2181volumes: # 挂载数据- /work/zookeeper/node2/data:/data- /work/zookeeper/node2/datalog:/datalog- /work/zookeeper/node2/conf:/confenvironment:ZOO_MY_ID: 2ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=0.0.0.0:2888:3888;2181 server.3=zoo3:2888:3888;2181networks:default:ipv4_address: 172.18.0.15zoo3:image: zookeeperrestart: alwaysprivileged: truehostname: zoo3ports:- 2183:2181volumes: # 挂载数据- /work/zookeeper/node3/data:/data- /work/zookeeper/node3/datalog:/datalog- /work/zookeeper/node3/conf:/confenvironment:ZOO_MY_ID: 3ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=0.0.0.0:2888:3888;2181networks:default:ipv4_address: 172.18.0.16networks: # 自定义网络default:external:name: zoonet

修改zookeeper配置文件zoo.cof：在/work/zookeeper/node1/conf目录下复制一份zoo.cfg.dynamic.next 重命名为：zoof

内容:

dataDir=/data
dataLogDir=/datalog
tickTime=2000
initLimit=5
syncLimit=5
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=true
server.1=0.0.0.0:2888:3888;2181
server.2=zoo2:2888:3888;2181
server.3=zoo3:2888:3888;2181

然后在当前目录下启动容器:

docker-compose -f docker-compose.yml up -d

利用docker ps 查看启动的容器：发现启动成功

[root@localhost /]# docker ps
