flume启动SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]

这个日志信息表示，Flume使用了SLF4J作为日志门面，但是实际的日志实现是Log4jLoggerFactory而不是SLF4J自己的默认实现。这是因为Flume默认使用了Log4j作为日志实现，而不是SLF4J提供的简单日志实现。

这个信息并不是错误，而是提醒你当前使用的日志实现是Log4jLoggerFactory。如果你想使用SLF4J提供的简单日志实现，你需要手动配置Flume使用SLF4J桥接Log4jLoggerFactory。你可以在Flume的配置文件中配置log4j.logger.org.apache.flume=INFO来控制Flume的日志输出级别。

这段文本是一个错误日志，它指出在运行某个程序时出现了错误。错误的具体信息是“Unrecognized option: --conf/opt/flume-1.9.0/conf”，说明程序无法识别选项“--conf/opt/flume-1.9.0/conf”。这个问题可能是由于程序在解析命令行参数时出现了错误导致的。

根据您提供的信息，看起来您的Flume Agent在向目标服务器发送事件时出现了连接错误：`Caused by: java.net.ConnectException: 拒绝连接: localhost/127.0.0.1:44444`。这个错误通常表示Flume Agent无法连接到目标服务器。可能的原因包括：

1. 目标服务器没有启动或网络不通畅。

2. 目标服务器的端口号不正确。

3. 防火墙等网络安全设置可能会阻止Flume Agent连接到目标服务器。

为了解决这个问题，您可以尝试以下几个步骤：

1. 确认目标服务器已经启动并且网络通畅，可以尝试使用`telnet`等工具进行测试。

2. 确认目标服务器的端口号是否正确。

3. 确认防火墙等网络安全设置是否允许Flume Agent连接到目标服务器。您可以尝试关闭防火墙或者添加相应的规则。

如果以上方法无法解决问题，建议您提供更详细的错误信息或日志信息，以便更好地诊断问题。
