Installing a graphical virtual host system on a VPS

After successfully purchasing buyvm, because I didn’t understand Linux and the website had a large number of visits, I had to learn how to use vps.
After some searching, I found that free graphical management tools include webmin, kloxo, etc.
Kloxo feels complicated, but not bad.
Webmin is also good, but it is still experimental.
A detailed report will be released later.
