@sebastian-roth Hi Sebastian, my bad, same exact error after I ran the iptable commands, forgot to indicate in my reply

Just did the commands as recommended in your last post,

@sebastian-roth Hi Sebastian, have run the commands as indicated. Running this in GUI mode with Terminal as Root

[root@sglfog01 jquek]# iptables -X
[root@sglfog01 jquek]# iptables -F
[root@sglfog01 jquek]# iptables -t nax -X
iptables v1.4.21: can’t initialize iptables table `nax’: Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
[root@sglfog01 jquek]# iptables -t nat -F
[root@sglfog01 jquek]# iptables -t mangle -X
[root@sglfog01 jquek]# iptables -t mangle -F
[root@sglfog01 jquek]# iptables -P INPUT ACCEPT
[root@sglfog01 jquek]# iptables -P FORWARD ACCEPT
[root@sglfog01 jquek]# iptables -P OUTPUT ACCEPT

After that, tried to open Fog Console and still fails

@sebastian-roth Hi Sebastian, noted and I attempted to upgrade PHP from v5.4.16 to v7.0.25, but it seems that it only upgraded certain components

I then tried to remove all versions of PHP by running yum -y remove php* and then installing PHP v7, but then it seems that it is not able to remove certain components of v5.4.16, resulting in a mixed environment where there are components of both v5.4.16 and v7.0.25 when I run the tail -n command

Error message when trying to load the Fog Console is as shown:

Network Error
A communication error occurred: “Operation timed out”

The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

For assistance, contact your service desk.

@wayne-workman Hi Wayne, thanks for spotting the error. Did another run and it also indicates SELINUX as permissive

cat /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=permissive
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

@tom-elliott Hi Tom, managed to upgrade PHP to version 7.0.25, but the Fog Console is still not launching

[root@sglfog01 jquek]# php -v
PHP 7.0.25 (cli) (built: Oct 27 2017 13:55:11) ( NTS )
Copyright 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright 1998-2017 Zend Technologies
with Zend OPcache v7.0.25, Copyright 1999-2017, by Zend Technologies

Any other ideas or suggestions?

@sebastian-roth Hi Sebastian, I managed to check out the contents of my SELINUX Config file by running this command using my root account,

cat /etc/systemconfig/selinux

# 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=permissive
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are pr$
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

And it does seem my SELINUX has already been set to permissive

And running the getenforce command does reveal my SELINUX to be permissive as well

[root@sglfog01 jquek]# getenforce
Permissive

And these are my httpd logs today as requested

@wayne-workman Hi Wayne, yes, I have seen and followed the article you posted to the dot, but I still ended up with this problem

Hi Sebastian,

Sure, I will run the command getenforce as root and then post the output here tomorrow

May I know by apache error log, you are referring to this? tail -n 100 /var/log/httpd/error_log

Thank you in advance

Hi Sebastian,

Thank you for your advice. Unfortunately, I have already performed the steps in your reply

I re-ran them in multi-user mode as the root account again and rebooted in graphical mode and still the Fog Management Console was showing me the hourglass

I have tried both 10.30.4.240/fog/management and localhost/fog/management and there is no difference

Please kindly advise, thank you!

Hi All,

Would really appreciate some help as I have been banging my head against the wall for a week. Re-setup CentOS7 and Fog numerous times and this is my 4th attempt with a clean CentOS 7 setup with clean install of Fog 1.4.4

I am still unable to get the Fog Management Console to launch and getting a network error. I have followed the suggestions in the Fog Wiki to run the following command, tail -n 100 /var/log/httpd/error_log, and these are the results,

[root@sglfog01 jquek]# tail -n 100 /var/log/httpd/error_log

These are the settings in my /var/www/html/fog/lib/fog/config.class.php

{
    define('DATABASE_TYPE', 'mysql'); // mysql or oracle
    define('DATABASE_HOST', 'localhost');
    define('DATABASE_NAME', 'fog');
    define('DATABASE_USERNAME', 'root');
    define('DATABASE_PASSWORD', "");
}

These are the setting in my /opt/fog/.fogsettings

installtype='N'
snmysqluser='root'
snmysqlpass=''
snmysqlhost='localhost'
installlang='1'

Any advice is appreciated, thank you!
