最新版本的 zookeeper 已经使用了 maven 进行管理了、不再需要安装 Ant
下载完成之后、使用 Idea 作为一个 maven 项目打开
拷贝配置文件
- 拷贝
zoo_sample.cfg文件至相同文件夹下，名为：zoo.cfg，配置全部使用默认； - 创建
/tmp/zookeeper目录、用于存放 zk 数据. - 拷贝
log4j.properties文件至：zookeeper-server/src/main/resources，文件名还是log4j.properties不变. - 将
resource标记为Resources Root
增加启动项
找到类 org.apache.zookeeper.server.quorum.QuorumPeerMain
在参数中加上 conf/zoo.cfg
修改pom文件中scope
将 scope 注释掉

执行server
执行 main 方法前建议执行命令 mvn clean install -DskipTests

启动成功
执行client
如 server 一般、配置入口类 org.apache.zookeeper.ZooKeeperMain
将下面的依赖的 scope 注释掉
<dependency> <groupId>commons-cli</groupId> <artifactId>commons-cli</artifactId> </dependency> 复制代码
