Problem Description
In Graph, Chinese fonts cannot be displayed (the font becomes "square" or not displayed at all), as shown in the following figure:
problem causes
This is not "garbled", but a missing font. In Zabbix, pictures are used to present chart data, and the corresponding font files need to be found when rendering fonts on pictures. If the font is not configured correctly (the font does not support Chinese or the font cannot be found), the font cannot be rendered in the picture, and squares will be displayed or this is completely blank.
solution
Search for the ttf keyword in the code, and then gradually track down the font loading path.
Debian and Zabbix ???
#!/bin/sh
# Install fonts containing Chinese fonts
apt-get install fonts-wqy-microhei
# update alternative zabbix -frontend-font
update-alternatives --install /usr/share/zabbix/fonts/graphfont.ttf \
zabbix -frontend-font /usr/share/fonts/truetype/wqy/wqy-microhei.ttc 10
# Configure to use wqy-microhei.ttc font
update-alternatives --config zabbix -frontend-font
CentOS and Zabbix
Applicable to CentOS 6.9, CentOS 7.x release version:
#!/bin/sh
# You can also use your favorite fonts, whatever you want, you need Chinese fonts
yum install -y wqy-microhei-fonts.noarch
# CentOS release 6.9 (Final) and Zabbix 4.2
update-alternatives --install /usr/share/zabbix/assets/fonts/graphfont.ttf \
zabbix-web-font /usr/share/fonts/wqy-microhei/wqy-microhei.ttc 10
# CentOS Linux release 7.5.1804 (Core) and Zabbix 4.0 .1
update-alternatives --install /usr/share/zabbix/assets/fonts/graphfont.ttf \
zabbix-web-font /usr/share/fonts/wqy-microhei/wqy-microhei.ttc 10
