Docker容器嵌入式开发：Ubuntu上配置Spark环境的基本步骤

# 1. 更新Ubuntu系统
sudo apt-update
sudo apt-upgrade
 
# 2. 安装Java环境
sudo apt install default-jdk
 
# 3. 安装Scala
echo "deb https://downloads.lightbend.com/scala/2.12.X/ ubuntu bionic main" | sudo tee -a /etc/apt/sources.list.d/scala.list
curl -s https://downloads.lightbend.com/scala/2.12.X/DEB-GPG-KEY-scala | gpg --dearmor | sudo apt-key add -
sudo apt-get update
sudo apt-get install scala
 
# 4. 下载并解压Spark
wget https://downloads.apache.org/spark/spark-3.0.1/spark-3.0.1-bin-without-hadoop.tgz
tar -xvf spark-3.0.1-bin-without-hadoop.tgz
 
# 5. 配置环境变量
echo "export SPARK_HOME=/path/to/spark-3.0.1-bin-without-hadoop" >> ~/.bashrc
echo "export PATH=\$SPARK_HOME/bin:\$PATH" >> ~/.bashrc
source ~/.bashrc
 
# 6. 验证Spark安装
spark-shell

以上脚本提供了在Ubuntu系统上安装Spark环境的基本步骤。请注意，在实际操作中，您需要将下载链接替换为最新版本的Spark，并确保正确设置路径。
