I had an existing Amazon Linux EC2 instance running Apache 2.2 and PHP 5.3. After uninstalling the old versions of Apache PHP using (sudo yum remove 'php*' 'httpd*'), I then installed Apache 2.4 and PHP 7.1.

However, I am now unable to start Apache. It simply fails to start without returning any errors:

[ec2-user@srv ~]$ sudo service httpd start
Starting httpd:           [FAILED]

I have checked the error logs at /var/log/httpd/ - nothing.
I have checked the system error logs at /var/log/messages - nothing.

I have tried starting Apache using httpd -e debug but there are no errors shown. All this command outputs is a list of modules being loaded, and then nothing:

[ec2-user@srv ~]$ sudo httpd -e debug
[Wed Dec 06 15:27:05.088704 2017] [so:debug] [pid 12707] mod_so.c(266): AH01575: loaded module access_compat_module from /etc/httpd/modules/mod_access_compat.so
[Wed Dec 06 15:27:05.088924 2017] [so:debug] [pid 12707] mod_so.c(266): AH01575: loaded module actions_module from /etc/httpd/modules/mod_actions.so
(...)
[Wed Dec 06 15:27:05.107018 2017] [so:debug] [pid 12707] mod_so.c(266): AH01575: loaded module ssl_module from /etc/httpd/modules/mod_ssl.so
[Wed Dec 06 15:27:05.113433 2017] [so:debug] [pid 12707] mod_so.c(266): AH01575: loaded module php7_module from /etc/httpd/modules/libphp-7.1.so
[ec2-user@srv ~]$

And still, Apache is not running:

[ec2-user@srv ~]$ sudo service httpd status
httpd is stopped

I have tried disabling the libphp-7.1 module, and then I get a different debug error:

AH00526: Syntax error on line 11 of /etc/httpd/conf.d/nbn-raw.conf:
Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration

Which makes sense, because PHP is then not being loaded. So I suspect it is related to PHP 7.1.

The contents of /etc/httpd/conf.d/nbn-raw.conf:

Alias /nbn/ /var/www/html/nbn/

<Directory "/var/www/html/nbn">
        # allow .htaccess to do rewrites
        AllowOverride FileInfo AuthConfig Limit

        Options FollowSymLinks
        Order allow,deny
        Allow from all

        php_value include_path ".:/usr/share/pear:/usr/share/php:/var/www/html/nbn/rtc/lib/Pheanstalk:/var/www/html/nbn/rtc/lib"
</Directory>

I have also checked the syntax of the apache conf files in the /etc/httpd/conf.d directory, but there are no errors returned there either:

[ec2-user@srv ~]$ apachectl configtest
Syntax OK

Can anyone help me with this issue?
Can anyone suggest anything I might have missed, or any additional log files I could check?

Currently, I have a XenServer and XenCenter setup with my root account which allows me to manage all the VM's on the server.

I'd like to know if it is possible to create client accounts in XenServer which have permissions that are set so they can only manage 1 or 2 VM's instead of all the VM's on the server and the server itself.

So to clarify - I want to be able to create user accounts that do not have root privilages in XenServer so that other people can login and manage 1 or 2 VM's which are assigned to their account.

Is it possible to do this?
