OS：RHEL8
首先下载需要安装的字体，我这边下载的是阿里巴巴的字体。打开https://alibabafont.taobao.com/，按照要求下载自己需要的字体。
首先安装 ：fontconfig mkfontscale
yum install -y fontconfig mkfontscale
安装完毕就可以使用fc-list 命令查看系统中已经安装的字体.
fc-list
/usr/share/fonts/dejavu/DejaVuSerif-Bold.ttf: DejaVu Serif:style=Bold
/usr/share/fonts/paratype-pt-sans/PTS76F.ttf: PT Sans:style=Bold Italic

fc-list :lang=zh

/usr/share/fonts/google-droid/DroidSansFallback.ttf: Droid Sans:style=Regular
......
以上可以看到字体都放在/usr/share/fonts/这个目录下，我们将下载的字体上传到这个目录下。
进入到/usr/share/fonts/ 目录下：依次运行以下命令 建立字体索引信息，更新字体缓存。
cd /usr/share/fonts
mkfontscale
mkfontdir
fc-cache -fv
至此，字体安装完毕。可以通过fc-list :lang=zh来查看安装的字体：
fc-list :lang=zh
