前言
DevOps工具栈中基本工具安装是非常常见和重要的，比如NodeJS的安装，PM2的安装，Docker的安装等等。下面
Node安装
Node的安装步骤如下：
Step1. 下载gz安装包
cd ~/download
wget https://nodejs.org/dist/latest-v12.x/node-v12.22.12-linux-x64.tar.xz
Step2. 创建Node的安装目录
VERSION=v12.22.12
DISTRO=linux-x64
sudo mkdir -p /usr/local/lib/nodejs
sudo tar -xJvf node-$VERSION-$DISTRO.tar.xz -C /usr/local/lib/nodejs
Step3 设置环境变量
. ~/.profile
echo > ~/.profile
vim ~/.profile
把下面的配置加入到上面的配置文件~/.profile里面
# Nodejs
VERSION=v12.22.12
DISTRO=linux-x64
export PATH=/usr/local/lib/nodejs/node-$VERSION-$DISTRO/bin:$PATH
Step4 环境变量生效
. ~/.profile
Step5 验证是否安装成功
[root@iZ0jl7nhcg5nazavryytxkZ ~]# node -v
v12.22.12
[root@iZ0jl7nhcg5nazavryytxkZ ~]# npm -v
6.14.16
[root@iZ0jl7nhcg5nazavryytxkZ ~]# npx -v
6.14.16
[root@iZ0jl7nhcg5nazavryytxkZ ~]# npm version
{

uv: '1.40.0',
v8: '7.8.279.23-node.57',
zlib: '1.2.11'
}
pm2安装
pm2的安装比较简单，直接执行下面的命令
[root@iZ0jl7nhcg5nazavryytxkZ ~]# npm install pm2 -g

Docker安装
在Redhat企业版上安装Ｄｏｃｋｅｒ十分的简单，直接输入下面的命令 yum install docker
其输出如下：
[root@iZ0jl7nhcg5nazavryytxkZ ~]# yum install docker
