1Panel配置

1. 脚本安装

curl -sSL https://resource.fit2cloud.com/1panel/package/quick_start.sh -o quick_start.sh && sh quick_start.sh

2. 配置镜像加速

在容器-> 配置中设置，否则安装软件会失败。

https://docker.211678.top
https://docker.1panel.live
https://hub.rat.dev
https://docker.m.daocloud.io
https://do.nark.eu.org
https://dockerpull.com
https://dockerproxy.cn
https://docker.awsl9527.cn

3. 容器安装组件

通过应用商店直接安装了kafka、mysql组件。

mysql组件安装完成，可以直接连接成功的。

验证本地程序发送kafka测试。

  def main(args: Array[String]): Unit = {val topic = "test"val props = new Properties()props.setProperty(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,"192.168.80.100:9092")props.setProperty(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,classOf[StringSerializer].getName)props.setProperty(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,classOf[StringSerializer].getName)val producer = new KafkaProducer[String,String](props)var a = 0for(a <- 1 to 10){println(a)val metadata = producer.send(new ProducerRecord(topic, "key" + a)).get()println(s"topic:${metadata.topic()} partition: ${metadata.partition()} offset:${metadata.offset()}")}producer.close()}

在验证kafka组件连接时，出现下面异常。

24/08/13 16:14:25 WARN NetworkClient: [Producer clientId=producer-1] Error connecting to node 1Panel-kafka-FHRb:9092 (id: 0 rack: null)

这里连接无法识别是容器的名称 1Panel-kafka-FHRb 不能识别。

192.168.80.100是我本地的虚拟机IP地址。
刚才的错误是我本地电脑连接时出现的，所以最直接的办法，在本地host添加映射。
注意：这里是我本地机器添加的映射

192.168.80.100 1Panel-kafka-FHRb

再次通过程序发送kafka成功。
