CentOS7.5+ANSYS19.2
刚接触这个，折腾了一天才搞好，记录一下
Centos7.5下载
https://archive.kernel.org/centos-vault/7.5.1804/isos/x86_64/
用Chrome下载速度比较慢，几百K/s，还经常失败，开了迅雷会员，复制链接在迅雷中下载比较快，能达到5-7M/s。
系统盘制作
用的rufus-3.20（链接：https://pan.baidu.com/s/1ZknJf2x_S6b5LeWqtV1CBg?pwd=7ax2 提取码：7ax2 ）
插上U盘，注意U盘会被格式化，打开rufus
这个U盘以前存了CentOS7.9的系统，所以我这里设备名字变成了CentOS7。
选择上面下载好的镜像文件，点击开始。
装系统
用的旧笔记本，型号联想z40-70，重新安装的CentOS系统，没有保留原本的Windows，电脑里原本的文件也都会被删掉。
U盘插到笔记本上，按开机键之后一直按Fn+F2，进入BISO
通过方向键选择USB设备，根据右侧提示按Alt+F6将USB上移至第一位，按Alt+F10保存并退出，或者进入EXIT选择Exiting Saving Changes保存并退出。
之后选择install centos7，正常开始安装，选择安装位置，有一点要注意软件选择默认的最小安装是没有图形界面的，要选择GUI或者GNOME才有图形界面。之后重启完成安装。
U盘识别
ANSYS的安装包我通过U盘拷贝的，但是CentOS无法识别NTFS和exFAT格式的U盘。
用命令su root切换到root用户，在终端输入以下命令，前两行是NTFS的，后两行是exFAT（参照以下两篇文章https://blog.csdn.net/qq_49590218/article/details/117734146 https://blog.csdn.net/u013948852/article/details/99849262）
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum install ntfs-3g
yum install -y http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
yum install exfat-utils fuse-exfat
ANSYS安装
按照硫酸亚铜大佬的教程安装（https://www.cnblogs.com/liusuanyatong/p/11259608.html），基本与视频中一样，只有在后面运行的时候，终端多出一条Qt的警告Qt: Session management error: None of the authentication protocols specified are supported，不影响使用，参考这篇文章（https://blog.csdn.net/qq_43213352/article/details/89043034），切换非root用户启动就没有警告了。
这一过程终端显示的内容如下：
