1.1 查看系統環境
[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

1.2.1 關閉防火牆
[root@localhost ~]# /bin/systemctl stop firewalld
[root@localhost ~]# /bin/systemctl disable firewalld
1.2.2 關閉selinux
[root@localhost ~]# getenforce #查看selinux是否開啟
Enforcing #enforcing表示selinux開啟的，
[root@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config #修改配置文件，需要重啟才后永久關閉
[root@localhost ~]# setenforce 0 #臨時關閉selinx
[root@localhost ~]# getenforce #查看是否關閉
Disabled
二、安裝epel源

3.6 升級node到穩定版
[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、升級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、驗證是否是最新穩定版
[root@localhost ~]# node -v
v12.18.2
[root@localhost ~]# npm -v
6.14.5
3.9、n工具指定node版本，命令打包編譯
n exec 12 cnpm install
注釋：
n：為指定使用的工具
exec：命令使用的方法
12：為node版本
cnpm：執行的工具
install：執行安裝命令
