Lets try and reset the Security Credentials and see if that resolves the issue.
In the XI GUI, Click on Admin > Reset Security Credentials and click on the Update Credentials button.
Try that and let us know how it works for you.

Also, what's the output of ls -l /usr/local/nagiosxi/html/includes/components/ccm/?

I will reset the security credentials and try the upgrade again.

Same error as before

Posted: **Fri Jul 14, 2017 3:05 pm**

There is a permission issue with that PHP script causing the Apache 500 error.
To fix it, login as root to the server and run the following

Code: Select all

chown nagios.nagios /usr/local/nagiosxi/html/includes/phpmailer/PHPMailerAutoload.php
chmod 640 /usr/local/nagiosxi/html/includes/phpmailer/PHPMailerAutoload.php

If that is resolved, and you are still getting the SQL login error, login to the XI GUI and go to the Admin > Reset Security Credentials menu and just click the Update Credentials button without changing anything.
Then check and see if the SQL login error is resolved.

I don't have a PHPMailerAutoload.php file - this is all that's in the phpmailer folder

root@server phpmailer]# ls
class.phpmailer.php class.pop3.php class.smtp.php

I am back to a pre upgrade attempt - do I need to run the upgrade again for this file to be created?

Posted: **Mon Jul 17, 2017 8:30 am**

So I reran the install and now the file is there -

[root@Chunk includes]# cd phpmailer/
[root@Chunk phpmailer]# ls
class.phpmailer.php class.pop3.php class.smtp.php PHPMailerAutoload.php
[root@Chunk phpmailer]# ls -la

On thing to do is to verify the settings in this KB article if your system in behind a proxy server.
https://support.nagios.com/kb/article/n ... oxies.html
If after going through the KB article, you still have issues, do the following

Run this while logged in as root to the Nagios server.

Code: Select all

tail -f /var/log/httpd/*_log

Then try and login to the XI GUI and if you still cannot login, post the full output of the tail command.

I've already made all of the recommended proxy changes.

Looks like I got it working -

I found this thread https://support.nagios.com/forum/viewto ... 16&t=35730 and ran

Code: Select all

cd /usr/local/nagiosxi/html
find . -type f -exec chmod 640 {} \;
find . -type d -exec chmod 750 {} \;

I can now log into the system.

Thanks for the help

There are more permission issues with the PHP scripts that Nagios uses. Let's fix all of them by running the following as root.

Code: Select all

chown nagios.nagios /usr/local/nagiosxi/html/includes/*
chmod 640 /usr/local/nagiosxi/html/includes/*

If you still see the "failed to open stream" error in the ssl_error_log file, reset the permissions and see if you can login after they have been fixed.
