分享一次部署经历，docker+dubbo+zookeeper

安装：拉取指定版本镜像

docker pull zookeeper:3.4 

创建运行在后台的zookeeper容器

docker run -d --name=zk-1 zookeeper:3.4 docker run -d --name=zk-2 zookeeper:3.4 docker run -d --name=zk-3 zookeeper:3.4 

进入容器

docker exec -it zk-1 /bin/bash 

退出容器

exit 

查看zookeeper容器运行日志

docker logs -f zk-1 docker logs -f zk-2 docker logs -f zk-3 

[root@VM-8-9-centos ~]# docker run -d --name=zk-1 zookeeper:3.4 eb7a7e029aea2539845e6e091026bfe48a645e57d63154267d79e088549a0524 [root@VM-8-9-centos ~]# docker run -d --name=zk-2 zookeeper:3.4 2405fb92253f3822dc293b5bfd4510d7115836c47d884f42c761c601be326a54 [root@VM-8-9-centos ~]# docker run -d --name=zk-3 zookeeper:3.4 ea0949dfa1297fdc968cf218b388cb60b07c8147b6aed3c3e5f8ddfda00f31d9 [root@VM-8-9-centos ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ea0949dfa129 zookeeper:3.4 "/docker-entrypoint.…" 19 seconds ago Up 17 seconds 2181/tcp, 2888/tcp, 3888/tcp zk-3 2405fb92253f zookeeper:3.4 "/docker-entrypoint.…" 27 seconds ago Up 26 seconds 2181/tcp, 2888/tcp, 3888/tcp zk-2 eb7a7e029aea zookeeper:3.4 "/docker-entrypoint.…" 37 seconds ago Up 35 seconds 2181/tcp, 2888/tcp, 3888/tcp zk-1 

容器中没有vim等软件，需要先更新

apt update apt install vim apt install net-tools 

zookeeper配置文件zoo.cfg

clientPort=2181 dataDir=/data dataLogDir=/datalog tickTime=2000 initLimit=5 syncLimit=2 autopurge.snapRetainCount=3 autopurge.purgeInterval=0 maxClientCnxns=60 server.1=172.17.0.2:2888:3888 server.2=172.17.0.3:2888:3888 server.3=172.17.0.4:2888:3888 

启动命令

bash bin/zkServer.sh start bash bin/zkServer.sh start /conf/zoo.cfg 查看状态 bash bin/zkServer.sh status 关闭 bash bin/zkServer.sh stop 

修改过后，bash bin/zkServer.sh运行不生效，docker restart id
