Excerpt from fogsettings
snmysqluser='root' snmysqlpass='' snmysqlhost='localhost'The install wiki article had no mention of setting up a password or user, and when the fog installation script asked, I selected that the password was blank. Disk space is not an issue either:

Is selinux set to be permissive or disabled? Or is it still set as enforcing?
sestatussetenforce 0(temporary fix)Is iptables/firewalld?
systemctl status firewalld
iptables -L -n -
To reiterate, I followed the install guide on the wiki exactly.
selinux is set to permissive:
SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: permissive Mode from config file: permissive Policy MLS status: enabled Policy deny_unknown status: allowed Max kernel policy version: 28Status of firewalld:

Pulled from git for RC21, Fixed errors in the fogsettings file. During installation, a selinux alert was generated:
SELinux is preventing /usr/bin/passwd from ioctl access on the file /home/ullsadmin/git/fogproject/bin/error_logs/fog_error_1.3.0-RC-21.log. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that passwd should be allowed ioctl access on the fog_error_1.3.0-RC-21.log file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

@AngryScientist In permissive mode, SELinux generates messages as it would in enforcing, but it doesn’t take any action to block anything whatsoever. Please try what I posted below.

Okay, sorry Wayne, your post got lost in my text walls.[ullsadmin@localhost ~]$ mysql -D fog ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)This is beyond my knowledge…
EDIT: Restarting mysqld fixed the issue. Now I will see if it stays after reboot…
EDIT2: It does not stay, boooo. -
@AngryScientist When it throws the error again, try these and see if one works:
mysql -D fog -u root -h localhostmysql -D fog -u root -h 127.0.0.1 -

This sounds like a mariaDB (aka mySql) issue. And it sounds like it’s just not configured to start on startup if systemctl start mysqld.service fixes it. This article might could help.
https://mariadb.com/kb/en/mariadb/starting-and-stopping-mariadb-automatically/I thought that the database got configured to automatically start on the apt-get/yum install.
I have cent os 7 and have never had to do any sort of configuration for fog services to run on startup. -

In centos 7 the way to start maridadb on boot is probably:
systemctl eanble mysqldI’m still waiting to hear back on the commands I posted.
-
systemctl enable mysqldTypo correction!
I will reboot my FOG server later today and give you the results of your suggestions. Right now I am reveling in the wonders of 5GBps imagine speed. 1.2.0 on my old hardware topped out at 1.2GBps

A lot of that has to do with the performance improvements of FOG 1.3.0 RC, a change was made to how the images are compressed and decompressed for imaging and some people reported 50 to 100% speed increases.

RC-22 Officially released.
Please update and hopefully you’ll see all the latest goodies and what not. (Hopefully this will be fixed for you too.)
Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

I know how to do a git pull, but what is the official upgrade procedure? -
-
In very simple terms:
https://wiki.fogproject.org/wiki/index.php?title=Upgrade_to_trunk
Essentially, open a terminal.
Cd to the installer directory.
If you loaded the repo from git, make sure you’re on the dev-branch:
git checkout dev-branchEnsure you’re environment is setup without customizations:
git reset --hardPull the latest:
git pullCd to the BIN directory:
cd binInstall as normal.
./installfog.sh -yPlease help us build the FOG community with everyone involved.
