配置JDK

配置JDK。

1. 创建JDK安装目录。

   mkdir -p /usr/local/lib64/jvm/bisheng

2. 下载并解压JDK到对应的安装目录。

   wget -c https://mirrors.huaweicloud.com/kunpeng/archive/compiler/bisheng_jdk/bisheng-jdk-17.0.10-linux-aarch64.tar.gz -O - | tar -C /usr/local/lib64/jvm/bisheng/ -xzf - --no-same-owner

3. 创建自动配置脚本。

   cat > "${HOME}"/SetJavaAlternatives.sh << 'EOF'
   #!/bin/bash
   jvm_path=/usr/lib/jvm
   mkdir -p "${jvm_path}"
   jdk_home_path=/usr/local/lib64/jvm/bisheng/bisheng-jdk-17.0.10
   PRIORITY_ID=901700010
   update-alternatives --install "${jvm_path}"/java-17 java_sdk_17 "${jdk_home_path}" "${PRIORITY_ID}"
   update-alternatives --install "${jvm_path}"/java-17-openjdk java_sdk_17_openjdk "${jdk_home_path}" "${PRIORITY_ID}"
   update-alternatives --install "${jvm_path}"/java-openjdk java_sdk_openjdk "${jdk_home_path}" "${PRIORITY_ID}"
   for BinFilePath in "${jdk_home_path}"/bin/*; do
     if [ -x "${BinFilePath}" ]; then
         BinFileName="$(basename "${BinFilePath}")"
         update-alternatives --install /usr/bin/"${BinFileName}" "${BinFileName}" "${BinFilePath}" "${PRIORITY_ID}"
     fi
   done
   for ManFilePath in "${jdk_home_path}"/man/man1/*; do
     if [ -f "${ManFilePath}" ]; then
         ManFileName="$(basename "${ManFilePath}")"
         update-alternatives --install /usr/share/man/man1/"${ManFileName}" "${ManFileName}" "${ManFilePath}" "${PRIORITY_ID}"
     fi
   done
   EOF

4. 执行自动配置脚本。

   /bin/bash "${HOME}"/SetJavaAlternatives.sh

5. 移除自动配置脚本。

   rm -rf "${HOME}"/SetJavaAlternatives.sh

6. 配置JDK环境变量。
   1. 一键设置Java环境变量。

      cat > /etc/profile.d/JavaEnvironmentVariable.sh << 'EOF'
      # SET JDK Enviroment
      JAVA_HOME=/usr/lib/jvm/java-17
      PATH=$PATH:$JAVA_HOME/bin
      export JAVA_HOME PATH
      EOF

   2. 加载系统环境变量。

      source /etc/profile
