安装字体配置和中文语言包

sudo yum install -y fontconfig langpacks-zh_CN.noarch

检查是否已有中文字体：

fc-list :lang=zh

$root@xla001 alternatives$ # fc-list :lang=zh
/usr/share/fonts/google-noto-cjk/NotoSansCJK-DemiLight.ttc: Noto Sans CJK TC,Noto Sans CJK TC DemiLight:style=DemiLight,Regular

/usr/share/fonts/google-noto-cjk/NotoSerifCJK-Black.ttc: Noto Serif CJK SC,Noto Serif CJK SC Black:style=Black,Regular

/usr/share/fonts/google-noto-cjk/NotoSansCJK-Light.ttc: Noto Sans CJK SC,Noto Sans CJK SC Light:style=Light,Regular

/usr/share/fonts/google-noto-cjk/NotoSansCJK-Black.ttc: Noto Sans CJK SC,Noto Sans CJK SC Black:style=Black,Regular

/usr/share/fonts/google-noto-cjk/NotoSansCJK-Thin.ttc: Noto Sans CJK SC,Noto Sans CJK SC Thin:style=Thin,Regular

我们将google-noto-cjk/NotoSansCJK-DemiLight.ttc直接使用，将zabbix-web-ui 重命名

mv /etc/alternatives/zabbix-web-ui-font /etc/alternatives/zabbix-web-ui-font.bak

ln -sf重新创建软链接

ln -fs /usr/share/fonts/google-noto-cjk/NotoSansCJK-DemiLight.ttc /etc/alternatives/zabbix-web-font

ln -fs /usr/share/fonts/google-noto-cjk/NotoSansCJK-DemiLight.ttc /etc/alternatives/zabbix-web-ui-font

刷新一下页面，Zabbix 7.2图形中文字符乱码问题搞定，能正常显示中文。
