使用docker搭建zookeeper集群

使用docker搭建zookeeper集群

docker下zookeeper镜像构建

git clone https://gogs.cuisongliu.com/docker-library/zookeeper.git[/code] 
构建zookeerper的自定义镜像,需要修改基础镜像(只要是jdk 环境即可)

cd zookeeper
docker build -t jerry/zookeeper:latest .


配置集群zookeeper的网络设置
docker network 设置

docker network create zoo


配置集群zookeeper的公共配置
配置zoo.cfg 配置文件

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/data
clientPort=2181
dataLogDir=/opt/log
server.1=zk1:2888:3888
server.2=zk2:2888:3888
server.3=zk3:2888:3888
server.4=zk4:2888:3888
server.5=zk5:2888:3888
server.6=zk6:2888:3888


dataDir ：zookeeper的数据目录

clientPort： 外部访问端口

dataLogDir： zookeeper的日志目录

server.1=zk1:2888:3888 ： 节点端口之间通信

docker-compose的zookeeper集群配置
docker-compose.yml:

zoo1:
image: jerry/zookeeper:latest
restart: always
net: zoo
container_name: zk1
volumes:
- /mnt/data/zoo1:/opt/data
- /mnt/logs/zoo1:/opt/log
- /mnt/docker-project/zookeeper/zoo:/opt/zookeeper/conf
ports:
- "2181:2181"
expose:
- "2888"
- "3888"
zoo2:
image: jerry/zookeeper:latest
restart: always
net: zoo
container_name: zk2
volumes:
- /mnt/data/zoo2:/opt/data
- /mnt/logs/zoo2:/opt/log
- /mnt/docker-project/zookeeper/zoo:/opt/zookeeper/conf
ports:
- "2182:2181"
expose:
- "2888"
- "3888"
zoo3:
image: jerry/zookeeper:latest
restart: always
container_name: zk3
net: zoo
volumes:
- /mnt/data/zoo3:/opt/data
- /mnt/logs/zoo3:/opt/log
- /mnt/docker-project/zookeeper/zoo:/opt/zookeeper/conf
ports:
- "2183:2181"
expose:
- "2888"
- "3888"
zoo4:
image: jerry/zookeeper:latest
restart: always
container_name: zk4
net: zoo
volumes:
- /mnt/data/zoo4:/opt/data
- /mnt/logs/zoo4:/opt/log
- /mnt/docker-project/zookeeper/zoo:/opt/zookeeper/conf
ports:
- "2184:2181"
expose:
- "2888"
- "3888"
zoo5:
image: jerry/zookeeper:latest
restart: always
container_name: zk5
net: zoo
volumes:
- /mnt/data/zoo5:/opt/data
- /mnt/logs/zoo5:/opt/log
- /mnt/docker-project/zookeeper/zoo:/opt/zookeeper/conf
ports:
- "2185:2181"
expose:
- "2888"
- "3888"
zoo6:
image: jerry/zookeeper:latest
restart: always
container_name: zk6
net: zoo
volumes:
- /mnt/data/zoo6:/opt/data
- /mnt/logs/zoo6:/opt/log
- /mnt/docker-project/zookeeper/zoo:/opt/zookeeper/conf
ports:
- "2186:2181"
expose:
- "2888"
- "3888"


net 设置之前的zoo 网络

container_name：当前容器名称，设置名称好做集群。

docker-compose up -d


ps: 在zoo.cfg文件中定义的server机器上都创建dataDir和dataLogDir定义的目录，同时在dataDi目录下创建myid文件，该文件的内容根据server定义的不同而不同，如server.1 该文件的内容是1，server.2 该文件内容是 2，以此类推.
