Resolved All apache configuration files are missing

[Ivan_K]

When saving the Apache module configuration (the web interface was used), all Apache configs are lost. Attempting to restore them results in an error:

Не удалось настроить веб-сервер:Execution failed. Command: httpdmng Arguments: Array ( [0] => --reconfigure-all ) Details: Execution failed.

This problem happened on a hot server. Please help as soon as possible

Usually, it is caused by the fact that the Apache configuration file /etc/httpd/conf.modules.d/00-base.conf is missing. As this file belongs to the Apache package, reinstall this package:

# yum reinstall httpd

After that, to apply the changes, repair the web servers' configuration using the command plesk repair web.

What is the output of the command:

# ls -la /etc/httpd/conf.modules.d/

Like I say, there are a lot of configuration files missing.

 

[IgorG]

Make sure that module mod_unixd is enabled: Apache fails to start: undefined symbol: ap_unixd_setup_child

 

[Ivan_K]

I was able to run Apache. But now, some domains give the default page instead of the site (for example https://www.krephaus.ru/). And some of them redirect to another domain (for example Web Server's Default Page)

And I keep getting an error:

Although, apache is working:
