1.更新系统
由于这里是刚重装的纯净系统，所以需要先升级一下。

yum -y update

2.使用yum安装nodejs和npm
一般安装软件前最好更新一下，避免出现一些乱七八糟的错误。

curl --silent --location https://rpm.nodesource.com/setup_9.x | bash -
yum install nodejs -y
#验证一下
[root@YUN84231334 ~]# node -v
v9.11.2
[root@YUN84231334 ~]# npm -v
5.6.0
[root@YUN84231334 ~]# npx -v
9.7.1

运行过程：

[root@YUN84231334 ~]# curl --silent --location https://rpm.nodesource.com/setup_9.x | bash -

                           [-o source [source ...]] [-t token] [-e url] [-s]
                           [-h]


optional arguments:
  -v, --version                   output the version number
  -p port, --port port            specify server port
  -a address, --address address   specify server host
  -u url, --proxy-url url         request through upstream proxy
  -f host, --force-host host      force the netease server ip
  -o source [source ...], --match-order source [source ...]
                                  set priority of sources
  -t token, --token token         set up proxy authentication
