Apache Not Working

Post by patricklunney » 2017/12/04 18:52:13

Hi all, I've spent hours troubleshooting my apache config and browsed many forums, but have hit a roadblock.
I took the same httpd.conf file from a working apache server and am trying to use the IP until I get the DNS changed. I don't expect the sites to work yet because of the OpenID Connect setup but I should at least be able to start apache and hit index.html.

Here are the error logs:

Code: Select all

# service httpd start
Redirecting to /bin/systemctl start httpd.service
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

I do have virtual hosts set up in sites-enabled. Here are the important parts in httpd.conf:

Code: Select all



# Load config files in the "/etc/httpd/conf.d" directory, if any.
IncludeOptional conf.d/*.conf
IncludeOptional sites-enabled/*.conf
AddDefaultCharset utf-8
And the sites-enabled.conf files look like this:

Code: Select all

<VirtualHost *:80>
   ServerName 10.227.82.72
   DocumentRoot /var/www/sites/
   ErrorLog /var/www/sites/error.log
   CustomLog /var/www/sites/requests.log combined
</VirtualHost>
Let me know if I can provide anything else.

Shouldn't ServerName be the dns entry your client's will be using ?
Run

Code: Select all

apachectl configtest
in order to find what is the issue.

Try restorecon -RFv /etc/httpd/ and see if that helps.
The future appears to be RHEL or Debian. I think I'm going Debian.

I actually got it to work by commenting out the custom logs.

Code: Select all

<VirtualHost *:80>
   ServerName 10.227.82.72
   DocumentRoot /var/www/sites/
   # ErrorLog /var/www/sites/error.log
   # CustomLog /var/www/sites/requests.log combined
</VirtualHost>
And that did it. Any idea why that would cause an issue?

Make sure the path /var/www/sites/ exists. Seems more appropriate for them to be somewhere like /var/log/httpd/sites/.

Selinux prevents the apache to write outside the predefined constraints.
You can use

Code: Select all

semanage fcontext -a -t (context of /var/log/httpd) "/var/www/sites/*.log" && restorecon -RFvv /var/www/sites/
.

Note:I'm not sure if the regex is OK, you have to test it.Also replace the context type.

Don't write logs under /var/www as selinux sees writes there as an attempt to compromise your httpd server. Write them under /var/log/httpd where they're meant to be.
