在Amazon Linux 2安装SDKMan遇GLIBC_2.28未找到错误求助

在Amazon Linux 2 AMI（必须使用官方认证/打补丁镜像，无其他选择）上安装SDKMan，执行以下步骤无报错：

sudo curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"

但运行sdk version时出现错误：

/home/ec2-user/.sdkman/libexec/version: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /home/ec2-user/.sdkman/libexec/version)

系统GLIBC版本为2.26，无法通过yum升级到2.28（会损坏系统），且找不到SDKMan旧版本，求解决办法。

• 安装兼容旧GLIBC的SDKMan历史版本
  先查询SDKMan的历史版本列表：

  curl -s https://api.sdkman.io/2/candidates/sdkman/versions | jq .
  

  选择一个发布时间早于GLIBC 2.28的版本（比如5.12.0及之前），卸载当前SDKMan后手动安装指定版本：

  # 卸载现有SDKMan
  rm -rf ~/.sdkman
  # 替换$VERSION为找到的兼容版本号，例如5.12.0
  curl -s "https://get.sdkman.io/$VERSION" | bash
  source "$HOME/.sdkman/bin/sdkman-init.sh"
  

• 本地编译GLIBC 2.28，临时指定运行时库
  不替换系统GLIBC，编译本地版本供SDKMan单独使用：

  # 安装编译依赖
  sudo yum install -y gcc make bison
  # 创建编译目录并下载源码
  mkdir -p ~/glibc-build && cd ~/glibc-build
  curl -O https://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz
  tar xf glibc-2.28.tar.gz && cd glibc-2.28
  # 配置编译路径（安装到用户目录下的local-glibc）
  mkdir build && cd build
  ../configure --prefix=$HOME/local-glibc --disable-sanity-checks
  # 编译安装
  make -j$(nproc)
  make install
  

  为SDKMan添加别名，自动加载本地GLIBC：

  echo 'alias sdk="LD_LIBRARY_PATH=$HOME/local-glibc/lib:$HOME/local-glibc/lib64 sdk"' >> ~/.bashrc
  source ~/.bashrc
  

  之后直接运行sdk version即可正常使用。

• 手动管理候选工具，绕过SDKMan二进制依赖
  直接下载JDK、Gradle等工具到~/.sdkman/candidates对应目录，手动配置环境变量，无需依赖SDKMan的二进制执行文件，例如：

  # 下载JDK 17到候选目录
  mkdir -p ~/.sdkman/candidates/java/17.0.9
  curl -L https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.9%2B9/OpenJDK17U-jdk_x64_linux_hotspot_17.0.9_9.tar.gz | tar -xz -C ~/.sdkman/candidates/java/17.0.9 --strip-components=1
  # 配置环境变量
  echo 'export JAVA_HOME=$HOME/.sdkman/candidates/java/17.0.9' >> ~/.bashrc
  echo 'export PATH=$JAVA_HOME/bin:$PATH' >> ~/.bashrc
  source ~/.bashrc
