Upgrade to debian 9

[plegrand]

Server

• FOG Version: Running Version 1.4.2
• OS: Debian 8

Description

Hello,
I actually use Fog 1.4.2 on a clean Debian 8 installation.
I’m upgrading all my servers to Debian 9 and i was wondering if Fog will works with changes on Debian 9 :
PHP 7
mysql => maria db.

Can i upgrade my saver without risk about php7 and mariadb ?
Does someone already made it ?

Many thanks for your hrlp.

Hi,

There are several post about php7, https://forums.fogproject.org/topic/6285/php-7-0-0-finally-released
No problem with Maria DB

[plegrand]

Then it seems that there is no problem with php7 also. But i cant see for which version of fog it’s OK.
Then you think i can upgrade to debian 9 without probklem ?
Which version of fog are you using ? and what linux version ?

Thanks

[ch3i]

@plegrand I’m using debian 8 and FOG latest RC (Running Version 1.5.0-RC-8, SVN Revision: 6080).
Is it a VM ?

[plegrand]

@ch3i Unfortunately no

[ch3i]

@plegrand said in Upgrade to debian 9:

@ch3i Unfortunately no

Bad news… I’ll test an upgrade on my server at the end of september, I can’t do it before because I’m in deployment.

[plegrand]

@ch3i anyway i think i’m going to upgrade before backup everything.
I will tell you

May be i’ve got to update fog before to the latest stable version : 1.4.4 ?
Then you use mariadb already ?

[Sebastian Roth]

@plegrand Just too many variables in this equation. We sure cannot garantee the upgrage will work without hickup. Just make a proper backup of the whole system or at least full database and better images too.

Then give it a go. We are here to help you fix things if anything goes wrong!!

[plegrand]

@sebastian-roth Then i try
i will tell you if everything is OK

[plegrand]

Upgrade done.
No problem during upgrade
Log seems to be ok
I continue to test

Argh… after reboot :

It seems that during upgrade debian remove some php5 packages but doesn’t reinstall them in php7 version.
After reinstall them it seems to works

aptitude install php7.0-mysql libapache2-mod-php7 php7.0 php7.0-curl php7.0-curl php7.0-fpm php7.0-gd php7.0-mcrypt

I have now to test pxe boot capture and deploy

As said in https://forums.fogproject.org/topic/6285/php-7-0-0-finally-released/15
i add this lines :

php_ver="7.0"
php_verAdds="-7.0"
repo="php-${php_ver}"

But it doesn’t change anything
Any idea ?

[Quazz]

@plegrand You have to remove the php5 packages from the packages= line in /opt/fog/.fogsettings file, I believe.

[ch3i]

@plegrand said in Upgrade to debian 9:

repo=“php-${php_ver}”

I use the latest RC, and I’ve not the repo=“php-${php_ver}”

Can you check the packages config ? have you ?
packages=‘apache2 bc build-essential cpp curl g++ gcc gzip htmldoc lftp libapache2-mod-php5 libc6 libcurl3 m4 mysql-client mysql-server net-tools nfs-kernel-server openssh-server php5 php5-cli php5-curl php5-fpm php5-gd php5-json php5-mcrypt php5-mysqlnd php-gettext sysv-rc-conf tar tftpd-hpa tftp-hpa unzip vsftpd wget xinetd zlib1g’

In my case I have php5 packages…

[plegrand]

This is exactly that i wanted to ask :
Do i have to modify manually this line then remove php5 packages and replace by php7.0 package .

https://wiki.fogproject.org/wiki/index.php?title=.fogsettings#packages

i will try on Monday and will report here the result

[Wayne Workman]

@plegrand Debian 9 would have to use the php 7 packages. I can assure you that the installer works on a clean installation of Debian 9, but I’ve not tested an upgrade from older Debian 8. If you look in my signature, you’ll see some automated tests centered around the fog installer. All those tests are with 100% clean OSs/installs.

In the past, people who have upgraded their OSs on FOG servers have had mixed success. When it goes right, everything is just peachy. When it goes wrong we spend days - sometimes weeks - helping these people figure out the problems. I’d say it’s been about a 60/40 split, 40 being failure.

If you want to avoid the risks of upgrading, this is an article outlining step-by-step how to migrate: https://wiki.fogproject.org/wiki/index.php?title=Migrate_FOG

[plegrand]

@wayne-workman may be could you give me a copy of the .fogsettings file from a fresh install on Debian 9 ?
Thanks

[Wayne Workman]

@plegrand yeah one second.
