pm2 安装

centos7.9 版本 
以下是在 CentOS 7.9 上使用 nvm 安装 Node.js 的步骤：安装 nvm：bashCopy Codecurl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash在终端中重新加载 shell 配置或打开一个新的终端窗口：bashCopy Codesource ~/.bashrc安装适用于您的系统的 Node.js 版本。例如，您可以尝试安装 v14.17.6：bashCopy Codenvm install v14.17.6使用 nvm 切换到安装的 Node.js 版本：bashCopy Codenvm use v14.17.6确认 Node.js 版本已切换成功：bashCopy Codenode -v现在，您应该能够使用较新版本的 Node.js，而不会出现与 glibc 版本不兼容的错误。npm install pm2 -gpm2 结合pm2 进行脚本控制
