# 安装最新版 Nodejs
Nodejs 比其他的软件好安装多了，直接去官网下载 Linux Binaries (x64)版
Nodejs-download
这里下载最新版本 21.6.1
# 安装并配置环境变量
下载下来解压之后放到 /usr/local/node 下
然后去配置环境变量
# 配置环境变量
进入 /etc/profile.d 目录下，创建一个 web.sh 文件
将之前的 nginx mysql redis 都加到环境变量里来
#/etc/profile.d/web.sh | |
export PATH="/usr/local/redis/bin:/usr/local/nginx/sbin:/usr/local/mysql/bin:/usr/local/node/bin:$PATH" |
然后执行 source /etc/profile
现在就可以在任何目录下使用 node 了
# 安装 yarn,pnpm 和 pm2
经过这几年的 nodejs 开发，发现 yarn 和 pnpm 的用法更简单高效，所以选择安装这 2 个
npm install -g yarn pnpm pm2 |
国内环境使然，yarn 和 pnpm 的代理都配置一下国内源，这里推荐淘宝源，中科大源和华为源
华为源: https://mirrors.huaweicloud.com/repository/npm/
中科大源: https://mirrors.tuna.tsinghua.edu.cn/npm/
淘宝源: https://registry.npmmirror.com
# 设置为淘宝源 | |
yarn config set registry https://registry.npmmirror.com | |
pnpm config set registry https://registry.npmmirror.com | |
npm config set registry https://registry.npmmirror.com |
# 设置 pm2 开机自启
[root@VM-12-5-opencloudos root]# pm2 startup | |
