一、安装包不存在

[root@localhost ~]# yum install -y node
    No package node available.
    Error: Nothing to do

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70]  
解决方案：

[root@localhost ~]# yum search node
    [root@localhost ~]# yum install -y npm
    [root@localhost ~]# node -v
    v6.17.1

二、、在这里可以查看全部版本及各种环境的安装文件  
https://nodejs.org/dist/

三、把 v6.17.1 升级到 v8.17.0  
1、安装n组件

[root@localhost ~]# npm install -g n

/usr/bin/n -> /usr/lib/node_modules/n/bin/n
    /usr/lib
    └── n@7.0.0

2、安装nodejs指定版本

[root@localhost ~]# n 8.17.0

安装效果

installing : node-v8.17.0
           mkdir : /usr/local/n/versions/node/8.17.0
           fetch : https://nodejs.org/dist/v8.17.0/node-v8.17.0-linux-x64.tar.xz
       installed : v8.17.0 (with npm 6.13.4)
    
    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"

说明：  
（1）默认nodejs安装路径是 /usr/bin/node  
（2）而n组件安装路径是 /usr/local/bin/node  
3、编辑系统环境变量

[root@localhost ~]# vim /etc/profile

4、在配置文件最后加上环境变量内容

export N_PREFIX=/usr/local/n/versions/node/8.17.0/ #node实际安装位置
    export PATH=$N_PREFIX/bin:$PATH

5、使配置的环境变量生效

[root@localhost ~]# source /etc/profile

6、查看当前版本

[root@localhost ~]# node -v
    v8.17.0

7、其它  
\]\# curl -sL https://rpm.nodesource.com/setup\_8.x | bash -

[root@localhost ~]# yum install -y nodejs
    [root@localhost ~]# npm -v
    6.13.4
    [root@localhost ~]# node -v
    v8.17.0

未完，后续扩展！
