My apache has stopped working

Help please, my apache has stopped working, when I try to activate it it says:

WARNING!

Job for httpd.service failed because the control process exited with error code.
See "systemctl status httpd.service" and "journalctl -xe" for details.

WARNING!

● httpd.service - Web server Apache
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

  Process: 21926 ExecStart=/usr/local/apache/bin/apachectl start (code=exited, status=1/FAILURE)

How can I solve it? I don't have too much knowledge.

Please provide more info about the problem.

1. Have you done some changes (changed apache config, recompiled apache, etc) before the problem appeared ?

2. Are there some errors in:

Code: [Select]

/usr/local/apache/logs/error_log
3. Try to restart apachce and show us output of "journalctl -xe":

Code: [Select]

service httpd restart
journalctl -xe

[root@server ~]# service httpd restart
Redirecting to /bin/systemctl restart httpd.service

I have not touched anything, nor have I compiled.

systemctl status httpd -l

what is output of above command?

There is a syntax error in some apache config file:

Code: [Select]

may 22 13:26:54 server.notices.com apachectl[47086]: AH00526: Syntax error on line 17 of /usr/local/apache/conf.d/vhost>
Unfortunately it isn't possible to identify which file causes the problem because the line is truncated in your output.

I recommend you to check the output of "journalctl -xe" more closely to identify the problematic file, open it in some editor and investigate the line 17 of the file. It will help you to understand which directive isn't recognized by apache. In case it doesn't help you then show us content of the problematic file.

Unfortunately the latest log provided by you doesn't contain anything about the error and doesn't allow to identify the problematic file either.

Try to identify the problematic file using the file:

Code: [Select]

/usr/local/apache/logs/error_log
Open it using "less", "vi" or some other editor and read content from the end to beginning.

Or just run:

Code: [Select]

/usr/local/apache/bin/apachectland read output.

Run a configuration test with apachectl:

Code: [Select]

sudo apachectl configtest
If everything is ok, the configtest command will return the message Syntax OK. If there is a syntax error, configtest will output the invalid configuration option with the filename and the line number.
