Error in apache2 when I try to do multicast tasks



  • Hello, I apologize for the English. I am updating from Fog 1.5.0 and in versions 1.5.1, 1.5.2, 1.5.3 and 1.5.4 I have had problems with apache2. When I try to create a Multicast task, I create the task and send Wake on Lan correctly, but they get stuck in boot.php and the portal stops, then I restart the apache service and everything normal, I can start the task manually starting each PC. Checking /etc/apache2/apache2.conf I have the following:

    I use Debian 8 64, probe reinstall in Debian 9 64 but the error remains. Has anyone else had this error?

    If this is still not solved, I would like to look into the php-fpm configuration and the log file related to php-fpm. From the apache side your initial post says session time has expired. I’m seeing a lot of multicast posts in the forum. There may be something else going on we don’t expect.



  • @tom-elliott you’re right, I’m using debian 8 and the default configuration of SELinux was in enforcing. With the command that you gave me, it changes to permissive.
    In the end I disabled SELinux completely, I did it in the following way:

    nano /etc/selinux/config
    # This file controls the state of SELinux on the system.
    # SELINUX= can take one of these three values:
    # enforcing - SELinux security policy is enforced.
    # permissive - SELinux prints warnings instead of enforcing.
    # disabled - No SELinux policy is loaded.
    SELINUX=disabled
    # SELINUXTYPE= can take one of these two values:
    # default - equivalent to the old strict and targeted policies
    # mls     - Multi-Level Security (for military and educational use)
    # src     - Custom policy built from source
    SELINUXTYPE=default
    
    # SETLOCALDEFS= Check local definition changes
    SETLOCALDEFS=0
    
    

    Thank you very much, I think it’s already working.

    Typically I see this when SELinux hasn’t been set to permissive/disabled.

    Please try running the command setenforce 0 and restarting php-fpm with: systemctl restart php-fpm httpd

    Mind you, I’m not sure what OS your FOG Server is running, but this really seems like an SELinux issue.

    I’ve been seeing this as well on Centos 7. (haven’t tested multicasting, it happens elsewhere too)

    I have switched Apache over to mpm_event (insread of mpm_prefork) which seems to help a lot. I don’t know if it’s safe to just switch to it on production (especially without configuration for it), but it’s possible there are some issues with prefork in combination with php-fpm.

    There isn’t really much of a point to use mpm_prefork if we’re using php-fpm anyway.



  • Checking more thoroughly I found a PHP error
    in /var/www/html/fog/lib/fog/fogcontroller.class.php
    I’m going to review a bit to see what I find. Here are bugs also reported?
