一、环境准备
1.1 查看系统环境
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
[root@localhost ~]# uname -m
x86_64
[root@localhost ~]# uname -r
3.10.0-862.el7.x86_64
1.2 关闭防火墙和selinux
1.2.1 关闭防火墙
[root@localhost ~]# /bin/systemctl stop firewalld
[root@localhost ~]# /bin/systemctl disable firewalld
1.2.2 关闭selinux
[root@localhost ~]# getenforce #查看selinux是否开启
Enforcing #enforcing表示selinux开启的，
[root@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config #修改配置文件，需要重启才后永久关闭
[root@localhost ~]# setenforce 0 #临时关闭selinx
[root@localhost ~]# getenforce #查看是否关闭
Disabled
二、安装epel源

完毕！
3.2、查看安装node

3.6 升级node到稳定版
[root@localhost ~]# n stable
installing : node-v12.18.2
mkdir : /usr/local/n/versions/node/12.18.2
fetch : https://nodejs.org/dist/v12.18.2/node-v12.18.2-linux-x64.tar.xz
installed : v12.18.2 (with npm 6.14.5)
Note: the node command changed location and the old location may be remembered in your current shell.
old : /usr/bin/node
new : /usr/local/bin/node
To reset the command location hash either start a new shell, or execute PATH="$PATH"
3.7、升级npm到最新
[root@localhost ~]# npm install -g npm
/usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js
/usr/local/bin/npx -> /usr/local/lib/node_modules/npm/bin/npx-cli.js
/usr/local/lib
└── npm@6.14.5
3.8、验证是否是最新稳定版
[root@localhost ~]# node -v
v12.18.2
[root@localhost ~]# npm -v
6.14.5
3.9、n工具指定node版本，命令打包编译
n exec 12 cnpm install
注释：
n：为指定使用的工具
exec：命令使用的方法
12：为node版本
cnpm：执行的工具
install：执行安装命令
