1、進入NodeJs官網，獲取到nodeJs的安裝地址（在linux下的安裝地址）
附上地址：https://npm.taobao.org/mirrors/node/v15.5.0/
我這里安裝的是15.5版本的。
2、然后將下載下來的tar文件拷貝到centos服務器上
- 建議使用XFTP上傳，如果直接拖動的服務器上，可能導致解壓縮的時候會失敗
3、在linux下進行安裝NodeJs
- 解壓文件
[root@localhost node]# tar -zxvf node-v15.5.0-linux-x64.tar.gz

- 配置系統環境變量
[root@localhost bin]# vim /etc/profile
在profile文件中末尾，添加node的環境變量
# setting nodejs path
export NODE_HOME=/opt/node/node-v15.5.0-linux-x64
export PATH=$NODE_HOME/bin:$PATH
然后保存退出
- 使環境變量生效
[root@localhost bin]# source /etc/profile
4、驗證是否安裝成功
[root@localhost /]# node -v
v15.5.0
[root@localhost /]# npm -v
7.3.0
出現上述結果證明安裝成功！
