zookeeper的zoo.cfg文件包含以下内容:
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/path/to/data
clientPort=2181
dataLogDir=/path/to/logs (可选)
其中,tickTime表示通信心跳时间,initLimit表示LF初始通信时限,syncLimit表示LF同步通信时限,dataDir表示保存zookeeper中的数据的目录,clientPort表示客户端连接端口,dataLogDir表示日志目录(可选)。

zookeeper 的zoo.cfg常用配置及含义
ZooKeeper是一个分布式协调服务,它通过维护分布式系统中的统一命名空间来协调不同的进程。在ZooKeeper的配置文件zoo.cfg中,可以设置一些常用的配置参数来影响ZooKeeper的行为。以下是一些常用的配置参数及其含义:
1. `tickTime`:ZooKeeper使用的基本时间单位(毫秒),用于心跳和超时。默认值为2000毫秒。
2. `dataDir`:ZooKeeper存储数据快照和事务日志的目录路径。
3. `clientPort`:ZooKeeper服务器监听客户端连接的端口号。
4. `initLimit`:ZooKeeper集群中的初始同步限制(以tickTime的倍数为单位)。它定义了一个follower初始连接到leader所允许的时间范围。
5. `syncLimit`:ZooKeeper集群中的同步限制(以tickTime的倍数为单位)。它定义了一个follower与leader之间保持同步所允许的时间范围。
6. `maxClientCnxns`:每个客户端IP地址允许的最大并发连接数。
7. `autopurge.snapRetainCount`:自动清理功能中保留的快照文件数量。
8. `autopurge.purgeInterval`:自动清理功能执行的时间间隔(小时)。
这些只是一些常见的配置参数,还有其他参数可以根据具体需求进行设置。在使用ZooKeeper时,根据实际情况调整这些参数的值可以改善ZooKeeper的性能和可靠性。
Using config: /opt/moudle/zookeeper-3.5.7/bin/../conf/zoo.cfg Starting zookeeper ... FAILED TO START
As an AI language model, I do not have access to the specific details of your system configuration or the error logs, so I cannot provide you with a specific solution. However, here are some general troubleshooting steps that you can try:
1. Check the zookeeper logs: The zookeeper logs may provide more information about the reason for the failure. Check the logs in /opt/moudle/zookeeper-3.5.7/logs/ and look for any error messages.
2. Check the zookeeper configuration file: Make sure that the zoo.cfg file is properly configured and all the necessary settings are set correctly.
3. Check the zookeeper port: Make sure that the port specified in the zoo.cfg file is not already in use by another process.
4. Check the zookeeper installation: Make sure that the zookeeper installation is complete and all the necessary dependencies are installed.
5. Check the system resources: Make sure that there are enough system resources (memory, CPU, disk space, etc.) available for zookeeper to run.
If none of these steps work, you may need to seek further assistance from a system administrator or a zookeeper expert.
