["ERROR 2005 (HY000): Unknown server host 'localhost' (-2)"," [404]"]

Hello, I have already found the topic of 2021, but the problem has not been solved there. I installed ceberpanel several times on Ubuntu 22.04 and when installing wordpress I get the same error [“ERROR 2005 (HY000): Unknown server host ‘localhost’ (-2)”," [404]"]. Does anyone know the solution, and why does cyberpanel installed from scratch make such errors? Thanks

Welcome @bestperson Happy you are here

Did you do cyberpanel installation on a clean os ?

Hello, yes 3 times from scratch, I chose different php for example 7,4 and 8, the result is the same
CyberPanel — панель управления для VDS сервера LiteSpeed Linux Ubuntu 20.04. Установка Wordpress - YouTube A year ago there were problems with ssl, but everything was fine with the installation of wordpress

Please use this tutorial and no other - 01 - Installing CyberPanel

Choose Ubuntu 20.04 or Ubuntu 22 if you can

This is exactly what I use, I have enough experience using it, but I can’t understand why wordpress is not installed

What do you mean ? You tried to install wordpress through manager or manually via file manager ?

I put it now especially for you on Ubuntu 22.04. Here is a video broadcast for you Установка и тестирование сайта на Cyberpanel - YouTube , here is the error log all that is there. If there are any other journal, tell me where to look and I’ll send them to you/CUiYufdqbto. 2023-03-13 14:54:11.988057 [INFO] [1869] [PlainConf] [virtualHostConfig:] module [cache] add param [storagepath /usr/local/lsws/cachedata/$VH_NAME]

Hello, is there anything you can do to fix this?

For the wordpress error did you try Wordpress: Installation failed. Error message: [404] - #46 by nick.chomey

Yes, I tried everything that is written there, the result is the same(I wrote about it at the very beginning)

In general, everything is fine on Ubuntu 20.04, at least there is no error, as well as free server support). All the best!
