一、官方网站下载安装包

 

Index of /zookeeper

选择需要的版本，下载相关压缩包（例：apache-zookeeper-3.7.0-bin.tar.gz ）

二、正式安装

1、解压目录，并且新建data目录

[root@i-slebi7x6 opt]# cd zookeeper/
[root@i-slebi7x6 zookeeper]# ls
apache-zookeeper-3.7.0.tar.gz
[root@i-slebi7x6 zookeeper]# tar -zxf  apache-zookeeper-3.7.0-bin.tar.gz
[root@i-slebi7x6 zookeeper]# ls
apache-zookeeper-3.7.0-bin  
[root@i-slebi7x6 zookeeper]# cd apache-zookeeper-3.7.0-bin
[root@i-slebi7x6 apache-zookeeper-3.7.0-bin]# ls
bin  conf  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.md
[root@i-slebi7x6 apache-zookeeper-3.7.0-bin]# mkdir data
[root@i-slebi7x6 apache-zookeeper-3.7.0-bin]# ls
bin  conf  data  docs  lib  LICENSE.txt  NOTICE.txt  README.md  README_packaging.md

2、复制conf目录下的zoo_sample.cfg为zoo.cfg。

[root@i-slebi7x6 conf]# cp zoo_sample.cfg zoo.cfg
[root@i-slebi7x6 conf]# ls
configuration.xsl  log4j.properties  zoo.cfg  zoo_sample.cfg

3、修改相关属性，配置dataDir地址。

zoo_sample.cfg

# 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=/tmp/zookeeper
# 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.
#
# http://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
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true

zoo.cfg

4、执行bin/zkServer.sh，启动zookeeper。

[root@i-slebi7x6 bin]# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/apache-zookeeper-3.7.0-bin/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

停止zookeeper

./zkServer.sh stop

5、启动CLI

[root@i-slebi7x6 bin]# ./zkCli.sh

深入理解 Mocha 测试框架：从零实现一个 Mocha

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集

(20200916 Solved)docker-compose up创建容器自动退出

问题描述如题，创建容器后自动退出了。并且docker start container无效解决方案原因是缺失了控制终端的配置，需要在docker-compose.yml中增加tty:true ，有时候这样也不行，需要再增加一个command:/bin/bash，命令不一定是这个，需要是一个不会退出的命令，然后用-d后台启动容器。Referencesdocker-compose启动容器后自动退出...
