Zookeeper 运行 或与标准端口 2181 用法无关？
Zookeeper running or not in relation to standard port 2181 usage?
CLOUDERA QUICKSTART 5.13如下
我不确定开箱即用的 zookeeper 是否 运行ning，如果是，那么它是否可以可靠地工作？我在独立模式下尝试从我下载的来自 kafka 提供的版本中 运行 zookeeper 时得到这个：

基本上，我发现观察结果与标准描述不相符。
由于您的错误说明您有一个
Address already in use
你应该弄清楚（正如 beny23 所说）哪个进程占用了那个端口：
lsof -i :2181
一旦你有一个动物园管理员 运行 你应该看到像这样的日志：

在你的配置中你应该定义服务器名称，我有这一行（我在 kubernetes 集群中部署了 zookeeper）
server.1=zookeeper-0.zookeeper.default.svc.cluster.local:2888:3888
无论如何你需要声明它（在你的 zoo.cfg 中）或者在启动时将它作为变量传递。

在你的配置中你应该定义服务器名称，我有这一行（我在 kubernetes 集群中部署了 zookeeper）
server.1=zookeeper-0.zookeeper.default.svc.cluster.local:2888:3888
无论如何你需要声明它（在你的 zoo.cfg 中）或者在启动时将它作为变量传递。
