Trunk install, fog.conf vhost file issue

Wayne Workman

wherever you put the fog installation files, look inside of bin/error_log, there will be numbered files in there that contain the output of commands from the installer. Let’s see what the last few lines in there are? Those last few are where it bombed.

The fog_error_8179.log file contains this:

@kurtblah What is the output of getenforce and sestatus and systemctl status firewalld ?

kurtblah

getenforce --> permissive

sestatus and firewalld status:

@kurtblah what happens if you manually run systemctl enable mysqld and systemctl enable mysql ?

kurtblah

@Wayne-Workman

[root@localhost ~]# systemctl enable mysqld
Failed to execute operation: No such file or directory
[root@localhost ~]# systemctl enable mysql
Failed to execute operation: No such file or directory

MariaDB is installed and works.

Wayne Workman

@kurtblah what about systemctl enable mariadb ?

kurtblah

systemctl enable mariadb

returns nothing. running the mysql command works fine.

[root@localhost bin]# mysql

The munged lines in the fog.conf vhost file and the installer output look to me like IPv6 addresses

kurtblah

From what I can tell, the installer is adding lines to the fog.conf file that keeps the httpd service from restarting.

I can take out the bad lines from the fog.conf file and the httpd service restarts as it should.

kurtblah

This is where the installer bombs out:

 * Setting up SSL FOG Server...................................OK
 * Restarting Apache2 for fog vhost............................Failed!

Wayne Workman

@kurtblah Ok, so what happens when that file is left alone, and you run systemctl restart httpd and then systemctl status httpd -l

kurtblah

[root@localhost bin]# systemctl restart httpd
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

@kurtblah Sorry for so many commands. I’m working through you like I would if I were there at the terminal.

What is the output of this: ip addr show

kurtblah

no problem. here’s the ip addr:

Wayne Workman

@kurtblah So, do you need IPv6 on this system for some reason?

If not, here’s instructions to turn it off for you:

backup interface config:
cp /etc/sysconfig/network-scripts/ifcfg-enp1s0 /etc/sysconfig/network-scripts/ifcfg-enp1s0.old

Edit the interface config:
vi /etc/sysconfig/network-scripts/ifcfg-enp1s0

Change these lines to off or zero or no:

NETWORKING_IPV6=no
IPV6INIT=no

If the lines are not there, you can try to add them.

Restart the interface - this command is sorta dangerous if the node is far away and the config is bad, the interface could fail to come back up, so keep that in mind:

ifdown enp1s0;ifup enp1s0

After doing this, try to re-run the fog installer and see what happens. Hopefully it works.

To put the old config file back if you want:

rm -f /etc/sysconfig/network-scripts/ifcfg-enp1s0
cp /etc/sysconfig/network-scripts/ifcfg-enp1s0.old /etc/sysconfig/network-scripts/ifcfg-enp1s0
ifdown enp1s0;ifup enp1s0

kurtblah

Disabling IPv6 did the trick. I ran:

 sudo echo "1" > /proc/sys/net/ipv6/conf/all/disable_ipv6

and the installer ran normally. I’ll need to shut it down permanently.

Thank you for your help. Is this IPv6 issue consistent in all of the builds?

-kurt

Wayne Workman

@kurtblah probably. And there isn’t the man power to do an overhaul on that. IPV6 will have to wait for the 2.0 rewrite.

Sebastian Roth

Not sure if we should still change the installer script to ignore those IPv6 addresses… @Developers ?

Wayne Workman

@Sebastian-Roth I think the installer should ignore IPv6 addresses.

Tom Elliott

I’m pretty sure I’ve added the code buts to only worry about IPv4 but could use confirmation of this.
