Resolved Can't start Apache Server..

[Jiji]

Hello,
Since last update, my website is offline. in the service window, i found that Apache server is not running, when i try to activate it i see : Unable to start service: Unable to manage service by apache_control_adapter: ('start', 'web'). Error:
when i try to open my website : 502 Bad Gateway OR 403 Forbidden.
I am running Plesk on Debian.
Any Help please ?

Have you tried running plesk repair web?

Plesk Repair Utility: Web

Also check
# apachectl -t
and the output of
# service apache2 start
for errors.

Could you please post the output of the apache-error-log?

 /var/log/httpd/error_log

And the output of:

service httpd status

Please also have a look here

 

[Bitpalast]

I can only repeat

Also check
# apachectl -t
and the output of
# service apache2 start
for errors.

 

[Jiji]

Could you please post the output of the apache-error-log?

 /var/log/httpd/error_log

And the output of:

service httpd status

Please also have a look here

Thak you for the reply, the output of the commande is :
service httpd status
● httpd.service
Loaded: not-found (Reason: No such file or directory)
Active: inactive (dead)

 

[Bitpalast]

You are on Debian, there it is
# service apache2 status

 

[Jiji]

And i don't have the /var/log/httpd/error_log file there is no httpd folder

 

[Jiji]

You are on Debian, there it is
# service apache2 status

Hi the output is :

[Bitpalast]

How about /var/log/apache2/error.log or /var/log/apache2/error_log?

Please also try
# apachectl -t

It checks the syntax of your configuration files. Most issues result from faulty configuration files or SSL configurations.

 

[Jiji]

Thank you,
root@stock:~# apachectl -t
Syntax OK

 

[Bitpalast]

In this case, the reason for the error is in /var/log/apache2/error.log (or error_log).

Here is the content of /var/log/apache2/error.log :

Now we're cooking ...
Please see this article with the solution: Unable to start Apache: Unable to find IPv4 address of server.example.com

Hi, thank you M. Peter it work fine for me can you tell me please why i found this after resolving the problem :
8828#0: *3364 open() "/httpdocs/wp-includes/js/jquery/ui/position.min.js" failed (13: Permission denied)

and the website don't work correctly

 

[Bitpalast]

This can have various reasons. For example, the owner of /httpdocs is not set to <username>saserv, or the permissions of /wp-includes is not <username>sacln. Maybe a security setting was applied that direct access to /wp-includes paths is disabled. Maybe the file or directory modes are incorrect (e.g. no read access for psaserv or psacln). Yo could start with
# plesk repair web <domainname>
(repairs web server configuration)
# plesk repair fs <domainname>
(repairs file permissions)
You could then remove security settings from the wordpress toolkit security page.

 

[Jiji]

i see thank you, here is the output of # plesk repair fs <domainname>
There are files or directories with suspicious permissions in the
root directory of the domain 'my domain .................... [WARNING]
httpdocs/wp-config.php

How can i remove security settings from the wordpress toolkit security page please ? and excuse my questions i'am new on Plesk usdaly i use cpanel :/

 

[Bitpalast]

In Wordpress Toolkit click on the "check security" button.
