默认的，通过 yum install -g nodejs 安装 nodejs 为 0.1x 版本的。
如果需要其他版本，则需要指定 nodejs 源。
6.x
- curl --silent --location https://rpm.nodesource.com/setup_6.x | bash -
5.x
- curl --silent --location https://rpm.nodesource.com/setup_5.x | bash -
4.x
- curl --silent --location https://rpm.nodesource.com/setup_5.x | bash -
0.1x
- curl --silent --location https://rpm.nodesource.com/setup | bash -
指定 6.x 版本以后，如下提示，表示成功
