1、拉取鏡像
sudo docker pull daocloud.io/daocloud/zookeeper:3.4.10
2、查看
sudo docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/hello-world latest e38bc07ac18e 9 days ago 1.85 kB
daocloud.io/daocloud/zookeeper 3.4.10 f2249a75c5d0 7 months ago 143 MB
daocloud.io/library/mysql 5.7.4 aa5364eb3d85 3 years ago 252 MB
3 運(yùn)行容器,設(shè)置了掛載卷，設(shè)置了3個(gè)暴露端口，
sudo docker run -it --volumes-from mysql-data --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 --restart always -d daocloud.io/daocloud/zookeeper:3.4.10
4、進(jìn)入容器，并配置zookeeper
sudo docker exec -it zookeeper /bin/bash
5 看下目錄結(jié)構(gòu)
bash-4.3# cd /
bash-4.3# ls
bin datalog etc media proc sbin tmp zookeeper-3.4.10
conf dev home mnt root srv usr
data docker-entrypoint.sh lib opt run sys var
注意，zookeeper的安裝目錄在 /zookeeper-3.4.10，而配置文件在/conf
bash-4.3# cd conf/
bash-4.3# ls
configuration.xsl log4j.properties zoo.cfg zoo_sample.cfg
bash-4.3# vi zoo.cfg
clientPort=2181
dataDir=/data
dataLogDir=/datalog
tickTime=2000
initLimit=5
syncLimit=2
maxClientCnxns=60
可以看到，它已經(jīng)把data目錄配置好了，就在根目錄下的data文件夾下。我們直接拿來用就行了
