Docker swarm 配置zk集群高可用

一创建服务器挂在目录

mkdir -pv /data/docker/composes/prod/middleware/zookeeper_cluster/zoo1/{conf,data,datalog};
mkdir -pv /data/docker/composes/prod/middleware/zookeeper_cluster/zoo2/{conf,data,datalog};
mkdir -pv /data/docker/composes/prod/middleware/zookeeper_cluster/zoo3/{conf,data,datalog};

二zk,yml 配置

version: '3.1'

  GIE-ECP-overlay-network:
    external: true

三配置文件配置

每个服务器目录下 /data/docker/composes/prod/middleware/zookeeper_cluster/zoo1/conf/zoo.cfg 配置

zookeeper1 zoo.conf

clientPort=2181
dataDir=/opt/zookeeper-3.4.13/data
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
server.1=0.0.0.0:2888:3888
server.2=zookeeper2:2888:3888
server.3=zookeeper3:2888:3888

zookeeper2 zoo.conf

clientPort=2181
dataDir=/opt/zookeeper-3.4.13/data
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
server.1=zookeeper1:2888:3888
server.2=0.0.0.0:2888:3888
server.3=zookeeper3:2888:3888

server.1=zookeeper3:2888:3888
server.2=zookeeper2:2888:3888
server.3=0.0.0.0:2888:3888

每个服务器目录下 /data/docker/composes/prod/middleware/zookeeper_cluster/zoo1/conf/log4j.properties配置

log4j.rootLogger=INFO,console,dailyFile
​
#TODO 发布到阿里云记得添加，另外控制台不输出(只输出warn或者error信息)
​
#log4j.logger.org.mybatis = INFO
​
log4j.logger.com.imooc.mapper=INFO
​
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.encoding=UTF-8
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%l] - [%p] %m%n
​
# 定期滚动日志文件，每天都会生成日志
​
log4j.appender.dailyFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.dailyFile.encoding=UTF-8
log4j.appender.dailyFile.Threshold=INFO
​
# TODO 本地日志地址，正式环境请务必切换为阿里云地址
​
log4j.appender.dailyFile.File=C:/logs/maven-ssm-alipay/log.log4j
log4j.appender.dailyFile.DatePattern='.'yyyy-MM-dd
log4j.appender.dailyFile.layout=org.apache.log4j.PatternLayout
log4j.appender.dailyFile.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%l] - [%p] %m%n

每个服务器配置myid 1 myid 2 myid 3

例如/data/docker/composes/prod/middleware/zookeeper_cluster/zoo1/data/myid 内容以为1
