Thank you blogger for sharing!
The key command: setfont
But you need to check the fonts to be written after setfont.
Enter the font directory: /lib/kbd/consolefonts, you can see all the fonts in the current system.
Then choose the largest one and execute:
setfont latarcyrheb-sun32
After running, you can see the obvious effect, if you can't find 32, you can also choose
setfont sun12x22
Make this font take effect at boot
Configure the statement "setfont latarcyrheb-sun32" into /etc/profile
echo 'setfont latarcyrheb-sun32' >> /etc/profile
Restart to take effect
Note : If the profile does not work, configure it to /etc/bashrc
