== SME 9, based on CentOS 6 ==

----
  
=== Prerequisites ===
+
The [http://wiki.contribs.org/index.php?title=SME_on_CentOS_6&oldid=18561 previous] instructions on how to install SME packages on CentOS 6 minimal are now out of date, but are still available in the history [http://wiki.contribs.org/index.php?title=SME_on_CentOS_6&action=history archive].  Please see [[SME9Alpha | SME9Alpha]] for the latest development steps.
* VIrtual machine (Vmware, Parallels or Virtualbox)
 
* Centos Minimal 64-bit architecture. 32-bit may follow later
 
* Access to EPEL, RPMForge and ATrpms repositories
 
* Setting up a RPM Building environment
 
  
=== Current status ===
+
The [http://wiki.contribs.org/index.php?title=SME_on_CentOS_6&oldid=18561 previous] version can be usefull as a starting point for:
* Identify all SME Server specific packages (John C.) See notes below.
+
* Creating an OpenVZ template for SME
* Setting up a RPM building environment (Ian W.)
+
* Building SME on other future CentOS versions
* booting CentOS 6 with the SME packages installed. (Daniel)
+
* Building SME on CentOS like distros
* Notes:
 
** Some RPMs need to be got from EPEL, RPMForge and ATrpms
 
** Needs a hack in yum-priority.conf
 
** selinux-policy-targeted and authconfig need to be removed
 
** You have to completely disable SELinux in /etc/sysconfig/selinux
 
** LOTS of things are broken, but then that's no great surprise.
 
** If we have a booting system we can start to look at fixing it.
 
** nke has been playing on 32 bit as well - I guess it will probably be worth replicating from 64 to 32 to see what happens.

<noinclude>[[Category:Howto]][[Category:SME9-Development]]
There are two paths that I can see to testing this:
 
 
 
1. Install CentOS 6 Minimal and try to add the equivalent 6 packages and see what is missing.
 
 
 
2. Install CentOS 6 Minimal and then try to add existing SME v8 (el5) packages
 
 
 
This how-to takes on route 1.
 
 
 
== Installing CentOS 6 minimal ==
 
First a few notes on CentOS 6 minimal, which is a bare bones install with very little on board. You can download a copy from one of the CentOS mirrors [http://www.centos.org/modules/tinycontent/index.php?id=30 here]
 
 
 
* As per above note, only use Virtual Machine for testing purposes. A good free VM package can be obtained [https://www.virtualbox.org/wiki/Downloads here]
 
* You might want to note down as much as possible so you yourself and others can reproduce the actions
 
* Don't use yum with the '-y' flag (install/upgrade without further user interaction) when using the yum install/upgrade commands. (beware copy/paste yum commands)
 
* you might want to note down all packages listed by yum to be installed/upgraded AND their dependencies
 
* When you are using 64-bit, please add '--exlcude=*86' at the end of the yum command line. This will prevent i386/i686 packages to be installed as 'required' dependencies
 
* Make regular snapshots of your Virtual Machine and describe them specifically. At least when you've reached an important milestone for yourself
 
 
 
 
 
=== Enable networking ===
 
 
 
Each boot you have to start the network etc etc. I decided it was better with the minimal install and touch as little as possible - if I could then get SME packages installed I could then use that to configure networking later.
 
 
 
To start the networking
 
./etc/sysconfig/network-scripts/ifup-eth eth0
 
 
 
or
 
dhclient eth0
 
 
 
or if you want to assign a IP address yourself.
 
ifconfig eth0 192.168.1.2
 
echo "nameserver 192.168.1.254" >> /etc/resolv.conf
 
route add default gw 192.168.1.254 eth0
 
 
To make your changes permanent you will need to edit the configuration file to make it active on boot. There is only the vi text editor, you can also install nano.
 
yum install nano
 
nano /etc/sysconfig/network-scripts/ifcfg-eth0
 
and set ONBOOT=”YES”
 
 
 
For the current purposes I decided to start manually each time so I that left the base settings as untouched as possible.
 
 
 
=== Enable SSH ===
 
 
 
On first run make sure we have ssh installed so we can use a terminal to login - much easier for copy and pasting stuff :
 
yum install open-ssh*
 
 
 
To get to the sshd service you will need this on each boot :
 
service iptables stop
 
service sshd start
 
 
 
== SME Server specific/required packages ==
 
To get a list of all specific SME Server packages you can run:
 
rpm -qa | grep 'smeserver\|e-smith'| sed -e 's/-[0-9].*//'|sort > smeserver-packages.txt
 
 
 
 
 
== SME Server specific/required perl packages ==
 
I decided to attack perl first as the SME stuff is written in it.
 
 
 
Here is a list of perl files from v8 and their equivalent in CentOS 6 if available....
 
 
 
To get a list of the file names in v8 either do (all file starting with the string 'perl'):
 
rpm -qa --qf '%{NAME}\n' name=perl\*
 
(Thanks Shad !)
 
 
 
or as per suggestion on the lists (All files containing the string 'perl')
 
rpm -qa | grep perl | sed -e 's/-[0-9].*//'
 
(Thanks Gordon !)
 
 
 
To get a alphabetically sorted list (which is easier to compare lists) add '|sort' to the commands above.
 
rpm -qa --qf '%{NAME}\n' name=perl\*|sort
 
rpm -qa | grep perl | sed -e 's/-[0-9].*//'|sort
 
 
 
To export the list to a plain text file you could do:
 
rpm -qa | grep perl | sed -e 's/-[0-9].*//'|sort > perl-list.txt
 
(Thanks HF !)
 
 
 
{{Note box|Which command will be the de facto standard to use so we are all talking about the same list??}}

I am now going to try and lob in the existing/missing el5 versions to see what happens. My guess is we will need to rebuild the required modules.
 
 
 
== FormMagick ==
 
Next will be an attack on FormMagick - there is no package in the default install so need to figure that out. In may indeed be horrible, but we can live with it for now.
 
 
 
Hopefully with perl and FormMagick installed, most of the SME stuff *should* basically install.
 
 
 
 
 
== Discussion, help and share ==
 
* Please consult/subscribe to the devs list for more information. [http://lists.contribs.org/mailman/listinfo/devinfo devinfo mailinglist] and in particular all threads starting with " SME on CentOS 6"
 
* There is a IRC channel where people who are interested in this effort 'hang out'. You're most welcome to drop by and/or join. It's free! ;-)
 
** You do not have to install anything to pay the channel a visit. All you need is a nice nickname and right click [http://webchat.freenode.net?channels=SME_server&uio=Mj10cnVlJjk9dHJ1ZSYxMT03Mg13 here] to open the channel in a new browser window or tab.

Back to SME Server 9.0 Development


Important.png Note:
This page is now obsolete, kept for reference only. see SME Server 9 Release Notes



The previous instructions on how to install SME packages on CentOS 6 minimal are now out of date, but are still available in the history archive. Please see SME9Alpha for the latest development steps.

The previous version can be usefull as a starting point for:

  • Creating an OpenVZ template for SME
  • Building SME on other future CentOS versions
  • Building SME on CentOS like distros
