记录word插入文字/图片，生成新word并转为pdf
安装 LibreOffice
sudo yum install libreoffice-headless -y查看是否成功
libreoffice --version手动运行转化：
libreoffice --headless --convert-to pdf --outdir '/www/wwwroot/K-HUISHOUYOU/public/output' '/www/wwwroot/K-HUISHOUYOU/public/output/doc_20250914151052_10852.docx' 2>&1安装完整的 LibreOffice，缺少 libreoffice-writer（处理 .docx 的模块）
sudo dnf install libreoffice-writer -y安装中文字体
查系统已安装完整的中文语言包
locale -a | grep zh查字体是否被安装
fc-list :lang=zh | grep -i noto安装字体：kkgithub.com 镜像
sudo wget -O /usr/share/fonts/noto-cjk/NotoSansCJKsc-Regular.otf \
https://kkgithub.com/notofonts/noto-cjk/raw/main/Sans/OTF/SimplifiedChinese/NotoSansCJKsc-Regular.otf设置权限：
sudo chmod 644 /usr/share/fonts/noto-cjk/*.otf更新字体缓存（这个重要）
sudo fc-cache -fv
