因为字体兼容性的原因,在显示中文时可能会有乱码出现

root@zabbix-server fonts]#pwd
/usr/share/zabbix/assets/fonts
#支持ttf和ttc后缀的字体文件
[root@zabbix-server fonts]#mv graphfont.ttf graphfont.ttf.bak
[root@zabbix-server fonts]#mv SIMYOU.TTF graphfont.ttf
[root@zabbix-server fonts]#ls
graphfont.ttf graphfont.ttf.bak
#注意:字体文件路径和名称的定义在文件/usr/share/zabbix/include/defines.inc.php中配置
#可以修改下面FONT_NAME指定新字体件,注意不需加文件后缀
[root@zabbix-server ~]#grep FONT_NAME /usr/share/zabbix/include/defines.inc.php
define('ZBX_GRAPH_FONT_NAME', 'graphfont'); // font file name
define('ZBX_FONT_NAME', 'graphfont');


root@ubuntu2004:/usr/share/zabbix/assets/fonts# mv SIMYOU.TTF graphfont.ttf
root@ubuntu2004:/usr/share/zabbix/assets/fonts# ls
graphfont.ttf  graphfont.ttf.bak  MSYH.TTC
root@ubuntu2004:/usr/share/zabbix/assets/fonts# grep FONT_NAME /usr/share/zabbix/include/defines.inc.php
define('ZBX_GRAPH_FONT_NAME',		'graphfont'); // font file name
define('ZBX_FONT_NAME', 'graphfont');
root@ubuntu2004:/usr/share/zabbix/assets/fonts#

注意:乱码和语言环境无关,英语环境也支持中文显示,但会有乱码
