zookeeper运行与配置
配置
注：以下为单例模式运行下的配置
# tar xvzf zookeeper-3.4.13.tar.gz
# mkdir -p /var/lib/zookeeper
# cd zookeeper-3.4.13/
// 手工创建zoo.cfg配置
# cd conf/
# vim zoo.cfg //内容如下
tickTime=2000
dataDir=/var/lib/zookeeper
clientPort=2181
说明：
dataDir
tickTime 供Zookeeper使用的基本时间单位（单位毫秒），用于执行心跳，同时最小会话超时时间将会是tickTime的两倍。
dataDir 必须指向一个已存在目录，用于存在内存数据库快照，除非特别指明，否则为更新至数据库的事务日志（the location to store the in-memory database snapshots and, unless specified otherwise, the transaction log of updates to the database.）
clientPort 用于监听客户端连接的端口。
运行
# cd ../bin
# pwd
/usr/local/zookeeper/zookeeper-3.4.13/bin
# ls
README.txt zkCleanup.sh zkCli.cmd zkCli.sh zkEnv.cmd zkEnv.sh zkServer.cmd zkServer.sh zkTxnLogToolkit.cmd zkTxnLogToolkit.sh
# zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.4.13/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
注：停止运行 zkServer.sh stop
测试
连接到ZooKeeper
# zkCli.sh -server 127.0.0.1:2181

Maven运行与配置
确保安装了java jdk并正确设置了JAVA_HOME
配置
下载bin.zip压缩包，解压到目标路径(例中 D:\Program Files\apache-maven-3.5.4\
)，设置MAVEN_HOME环境变量，如下
Cmd输入mvn -v测试
