CentOS7安装nodeJs
1、进⼊NodeJs官⽹，获取到nodeJs的安装地址（在linux下的安装地址）
2、然后将下载下来的tar⽂件拷贝到centos服务器上
建议使⽤XFTP上传，如果直接拖动的服务器上，可能导致解压缩的时候会失败
3、在linux下进⾏安装NodeJs
解压⽂件
[root@localhost node]# tar -zxvf node-v15.5.

配置系统环境变量
[root@localhost bin]# vim /etc/profile
在profile⽂件中末尾，添加node的环境变量
# setting nodejs path
export NODE_HOME=/opt/node/node-v15.5.0-linux-x64
centos7没有vim命令export PATH=$NODE_HOME/bin:$PATH
然后保存退出
使环境变量⽣效
[root@localhost bin]# source /etc/profile
4、验证是否安装成功
[root@localhost /]# node -v
v15.5.0
[root@localhost /]# npm -v
7.3.0
出现上述结果证明安装成功！
