FOG installation errors

@Sebastian-Roth You are absolutely correct. This server was built and is managing by another team outside of our institution. We don’t have direct control over it.

Sebastian Roth · Nov 11, 2019, 1:53 PM

@TaTa I don’t think it’s a good idea to install FOG on such a server!

That said we can still help you do this. Edit the file fogproject/lib/redhat/config.sh and jump to line 40. Change mysql mysql-server in that line to mariadb mariadb-server .

This is on your own risk!

TaTa · Nov 11, 2019, 7:56 PM

@Sebastian-Roth Thank you. What are the risks?

Sebastian Roth · Nov 11, 2019, 8:04 PM

@TaTa If you have NFS shares, FTP, Apache, TFTP services running on that server the FOG installer might mess up those configs.

I’m getting Installing package: mariadb-server..........................Failed! (Will try later)

@TaTa Please upload the latest install error log here so we can have a look.

@TaTa Ok, let’s see what you have installed already: rpm -qa | grep -i -e "mysql" -e "mariadb"

@TaTa Wow, that seems like a little mess. There is mariadb101u-config which comes from the IUS repo and then you have mysql-community-... packages installed as well. No ...-server as far as I can see. Do you know if there is meant to be a database server running on this machine? Maybe run ls -al /var/lib/mysql* to see if there are some DB files left. Just to get the full picture.

TaTa · Nov 11, 2019, 10:01 PM

@Sebastian-Roth I get ls: cannot access /var/lib/mysql*: No such file or directory.

Sebastian Roth · Nov 11, 2019, 4:05 PM

@TaTa Ok, so seems like there never was a DB server installed. To resolve this issue I’d consider removing the package mariadb101u-config manually. As you can see here it should hold the “config file my.cnf and my.cnf.d directory”. Probably best to take backup copies of those files before remove the package. Use find /etc -iname "*my*" to get a list of files to backup.

Then run yum remove mariadb101u-config and change fogproject/lib/redhat/config.sh again. Put in mysql-community-client mysql-community-server instead of mariadb mariadb-server and re-run the installer.

@Sebastian-Roth Thank you! I’m getting a bit further. The installer can’t set a password for fogproject account due New password: BAD PASSWORD: The password is shorter than 14 characters. Is there a way I can set it manually or change password length in the script so will be 14 characters or more?

Sebastian Roth · Nov 12, 2019, 4:53 PM

@TaTa Take a look at fogproject/lib/common/functions.sh line 1261. At the end of the line where it says .../dev/urandom | fold -w12 | head -n1) change the figure 12 to a higher value.

By the way. If you want to install with a proper root password set for the database you will run into an issue with the current version. I hope to get this fixed soon!

TaTa · Nov 12, 2019, 5:51 PM

@Sebastian-Roth I changed it to 14 and 16 but is getting this error. Looks like password is not complex enough

@TaTa The data being pulled in for the password is out of urandom, so it is not implausible that, as the log indicates, a given line may not include a digit or upper case letter. You may be able to run the installer a few more times and get a random password that conforms to the system’s password requirements. You may also be able to create a partial /opt/fog/.fogsettings with strong passwords compliant with your systems password policies. Format and settings are available in the Wiki. I haven’t tested this, but my understanding is that anything not set in .fogsettings is requested by the installer.

Edit: the setting you are likely interested in is password=.

TaTa · Nov 12, 2019, 9:27 PM

@Daniel-Miller I created the files but it’s still not working. This is a new installation. I don’t think it looks into .fogsettings before creating this new account.

TaTa · Nov 12, 2019, 3:57 PM

I no longer getting password too simple. It looks like it’s not accepting the password. I can set password for fogproject manually but the installation does not like this account created beforehand.

@TaTa hmm … weird. You might try using chpasswd instead of passwd. I think that is available in RHEL … maybe by default. If it is, in functions.sh#L1262, change:

echo -e "$password\n$password" | passwd $username >>$workingdir/error_logs/fog_error_${version}.log 2>&1

to

echo -e "$username:$password" | chpasswd >>$workingdir/error_logs/fog_error_${version}.log 2>&1

Don’t have a RHEL system handy to test it with, however.

Daniel Miller · Nov 13, 2019, 3:23 PM

@TaTa Actually, what is the result of getenforce?

Was searching around a bit and apparently, SELinux can cause some strange behavior…
