启动集群

docker-compose up

后台启动

docker-compose up -d

查看启动状态

docker-compose ps

查看主从关系:

echo stat | nc www.wenbronk.com 2181

可看另外两个端口 2182, 2183

还可以在启动时直接指定

docker run -d \
-p 2181:2181 \
--name zk1 \
--link zk2:zknode2 \
--link zk3:zknode3 \
--net foo \
-e SERVER_ID=1 \
-e ADDITIONAL_ZOOKEEPER_1=server.1=0.0.0.0:2888:3888 \
-e ADDITIONAL_ZOOKEEPER_2=server.2=zknode2:2888:3888 \
-e ADDITIONAL_ZOOKEEPER_3=server.3=zknode3:2888:3888 \
zookeeper

docker run -d \
-p 2182:2181 \
--name zk2 \
--link zk1:zknode1 \
--link zk3:zknode3 \
--net foo \
-e SERVER_ID=1 \
-e ADDITIONAL_ZOOKEEPER_1=server.1=zknode1:2888:3888 \
-e ADDITIONAL_ZOOKEEPER_2=server.2=0.0.0.0:2888:3888 \
-e ADDITIONAL_ZOOKEEPER_3=server.3=zknode3:2888:3888 \
zookeeper

docker run -d \
-p 2183:2181 \
--name zk3 \
--link zk2:zknode2 \
--link zk1:zknode1 \
--net foo \
-e SERVER_ID=1 \
-e ADDITIONAL_ZOOKEEPER_1=server.1=zknode1:2888:3888 \
-e ADDITIONAL_ZOOKEEPER_2=server.2=zknode2:2888:3888 \
-e ADDITIONAL_ZOOKEEPER_3=server.3=0.0.0.0:2888:3888 \
