个人简介

本文的大概内容：
一、业务场景：报错kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING
我通过docker命令启动kafka，进入kafka容器之后，过一二秒没做操作，就出现退出容器的情况，通过zookeeper客户端连接kafka配置的zookeeper发现可以连接的上，但是查看kafka日志却报错kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING
二、错误日志：Will not attempt to authenticate using SASL (unknown error) (org.apache.zookeeper.ClientCnxn)

由于kafka运行是通过docker镜像的方式运行的，而且zookeeper外部的客户端也可以连接上zookeeper就排除了，zookeeper的异常情况，那么剩下的只可能是kafka运行的命令出问题了，我之前的运行命令如下：
docker run -dit --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka \\
-p 9092:9092 \\
-e KAFKA_BROKER_ID=0 \\

-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 \\

-t wurstmeister/kafka
把监听的0.0.0.0改成服务器ip地址
docker run -dit --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka \\
-p 9092:9092 \\
-e KAFKA_BROKER_ID=0 \\

-e KAFKA_LISTENERS=PLAINTEXT://106.14.132.94:9092 \\
-v /etc/localtime:/etc/localtime \\
-t wurstmeister/kafka
但是还是有出错的情况：

奇怪的是zookeeper的节点有kafka相关的数据了
SASL全称Simple Authentication and Security Layer，是一种用来扩充C/S模式验证能力的机制。
三、解决方案
网上百度了一堆没用的，我一一列举出来
第一个说是通过官网发现，在zookeeper 3.4.5之前，sasl认证是没有办法规避的，在3.4.6版本后修复了这个bug，因为不停的去检测认证虽然对功能没有什么影响，但是比较耗费服务器性能，比较占用容器资源。zk升级到3.4.6+的版本，可我的版本是zookeeper-3.4.13，肯定是符合的，无效。
第二个说是让zookeeper绕过sasl安全机制，禁用sasl认证，直接向系统获取资源。在conf目录下的zoo.cfg文件添加配置，zookeeper.sasl.client=false，然后重启zookeeper，亲身试过，无效。
第三个说是端口开放的问题，防火墙啊，入口和出口规则限制啊，这些符合，因为我可以通过客户端工具连接zookeeper，所以不存在端口问题，无效。
第四个说是给zookeeper做安全配置，但是我的初衷是对Kafka客户端使用SASL身份验证，但不要求kafka对Zookeeper进行SASL身份验证，我不关心kafka < - > zookeeper之间的安全校验问题，我就想单纯的通过docker进行运行kafka，可以让我进到容器内部进行测试发送消息。所以我还在寻找绕开sasl认证的办法，通过在apache bug管理官网：https://issues.apache.org/jira/browse/ZOOKEEPER-1657，我大致看了看还是和上面类似的解决方案。
大致的意思就跟第一个说的差不多，不停的去检测认证虽然对功能没有什么影响，但是比较耗费服务器性能，比较占用容器资源。
下面的解决方案也如出一辙。
除此之外，还发现了一篇帖子的解决方案也大体相同
只不过我都尝试过，发现都不起效果。
然后我去查看有关SASL配置项
X509AuthenticationProvider.superUser：Java系统属性：zookeeper.X509AuthenticationProvider.superUser）支持SSL的方法，使ZooKeeper集合管理员能够以“超级”用户身份访问znode层次结构。当此参数设置为X500主体名称时，只有具有该主体的经过身份验证的客户端才能绕过ACL检查并拥有所有znode的完全权限。
zookeeper.superUser：Java系统属性：zookeeper.superUser）与zookeeper.X509AuthenticationProvider.superUser类似，但对于基于SASL的登录是通用的。它存储可以作为“超级”用户访问znode层次结构的用户的名称。
看了这些配置，发现并没什么作用。到这里我基本放弃了绕开sasl认证的办法了，网上也找不到更多有用的消息，还不如老老实实的配置安全认证，这里我参考了二篇博文，第一篇是集群模式的：https://blog.csdn.net/sdksdk0/article/details/95336382，第二篇是https://www.orchome.com/553。又熬到快十二点半了，熬不动了，睡觉睡觉，希望有大神可以帮忙解决这个绕开sasl认证的问题，至于权限认证的问题，等也时间再慢慢实现。这里我提供kafka和zookeeper的启动命令给大神作参考。
具体实现可参考：https://liaozhiwei.blog.csdn.net/article/details/120716913
早上起床接着排查
第五个说的是zookeeper客户端 和服务器连接时版本问题，不过我并没有用程序连接，无效
第六个说的是zookeeper服务器主动断开与客户端的连接问题，修改配置，无效
这个时候我去看了看zookeeper的日志信息，发现也报错了
这个时候，我将之前改过的配置都还原，把原有的镜像都删除，重新启动docker运行镜像
kafka
docker run -dit --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka \\

然后发现zookeeper的错误信息日志

又找了找，还是没什么用
用netstat查看网络连接状态
netstat -antp | grep 2181
用tcpdump抓包和wireshark分析
tcpdump -vv host 106.14.132.94 and port 2181 -w 2181.cap
tcpdump -r 2181.cap
没有发现什么有用信息，这个时候原来的sasl认证的错误信息没有了，出现了新的问题。
zookeeper还是老样子，可以连接上
后面我会持续更新这个bug的解决过程，直到彻底解决，也希望有大佬可以在评论区留下宝贵的经验，让我可以少走弯路。

以上就是今天要讲的内容，还希望各位读者大大能够在评论区积极参与讨论，给文章提出一些宝贵的意见或者建议，合理的内容，我会采纳更新博文，重新分享给大家。

以上是关于Will not attempt to authenticate using SASL (unknown error) (org.apache.zookeeper.ClientCnxn)的主要内容，如果未能解决你的问题，请参考以下文章
spark 写 hbase 数据库，遇到Will not attempt to authenticate using SASL (unknown error)
Will not attempt to authenticate using SASL (unknown error) (org
Will not attempt to authenticate using SASL (unknown error) (org.apache.zookeeper.ClientCnxn)
zookeeper 客户端连接报： Will not attempt to authenticate using SASL
Will not attempt to authenticate using SASL (unknown error) (org.apache.zookeeper.ClientCnxn)
为什么连接HBase报错：Will not attempt to authenticate using SASL (unknown error)？
