Docker(十一): 安装zookeeper
作者：互联网
docker-compose安装zookeeper
编写docker-compose.yml文件
version: '3.1'
services:
zoo1:
container_name: zoo1
image: zookeeper
hostname: zoo1
ports:
- 2181:2181
networks:
- zookeeper-network
volumes:
- /mydata/zookeeper/zoo1/data:/data
- /mydata/zookeeper/zoo1/conf/zoo.cfg:/conf/zoo.cfg
- /mydata/zookeeper/zoo1/logs:/datalog
restart: always
environment:
ZOO_MY_ID: 1
ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181
zoo2:
container_name: zoo2
image: zookeeper
hostname: zoo2
ports:
- 2182:2181
networks:
- zookeeper-network
volumes:
- /mydata/zookeeper/zoo2/data:/data
- /mydata/zookeeper/zoo2/conf/zoo.cfg:/conf/zoo.cfg
- /mydata/zookeeper/zoo2/logs:/datalog
restart: always
environment:
ZOO_MY_ID: 2
ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181
zoo3:
container_name: zoo3
image: zookeeper
hostname: zoo3
ports:
- 2183:2181
networks:
- zookeeper-network
volumes:
- /mydata/zookeeper/zoo3/data:/data
- /mydata/zookeeper/zoo3/conf/zoo.cfg:/conf/zoo.cfg
- /mydata/zookeeper/zoo3/logs:/datalog
restart: always
environment:
ZOO_MY_ID: 3
ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181
networks:
zookeeper-network:
driver: bridge
注意: 此时zookeeper集群是启动不起来的，查看日志/docker-entrypoint.sh: line 43: /conf/zoo.cfg: Is a directory
解决容器启动失败
在挂载文件夹/mydata/zookeeper/zoo{}/conf创建zoo.cfg文件, 赋权755
cd /mydata/zookeeper/zoo1/conf
rm -rf zoo.cfg/
touch zoo.cfg
chmod 755 zoo.cfg
将另外两个节点按照此命令修改。
此时启动依然启动不起来, 异常为:

分析原因为找不到myid文件。
将zoo.cfg文件修改, dataDir=/data myid文件存放在/data目录下
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.

# https://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours

## Metrics Providers
#
# https://prometheus.io Metrics Exporter

#metricsProvider.httpHost=0.0.0.0
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true
启动zookeeper集群
docker-compose -f docker-compose.yml up -d
在使用zookeeper3.6之后版本，zookeeper启动时会启用jetty容器，占用8080端口， 可在配置文件中admin.serverPort=8888进行修改
