| − | __TOC__
| |
| − | == SME 9, based on CentOS 6 ==
| |
| − | An overview of related SME9 development pages can be found [[:Category:SME9-Development|here]].
| |
| − |
| |
| − |
| |
| − | === Prerequisites ===
| |
| − | * VIrtual machine (Vmware, Parallels or Virtualbox)
| |
| − | * Centos Minimal 64-bit architecture. 32-bit may follow later
| |
| − | * <strike>Access to EPEL, RPMForge and ATrpms repositories</strike>
| |
| − | * [[Setting_up_RPM_Building_for_SME_Server|Setting up a RPM Building environment]]
| |
| − |
| |
| − | === User Feedback ===
| |
| − | Unstructured user feedback can be noted here: [[SME9DEV_user_feedback|SME9DEV user feedback]]. Issues that require developers attention should be logged in our Bug Tracker. (See below)

| − | [http://wiki.contribs.org/SME9BuildQueue#SME_9_Error_list_and_affected_packages SME 9 error list]
| |
| − |
| |
| − | === Considerations ===
| |
| − | * Primary and only goal for now is the transition of SME Server based on CentOS 5.8 to SME Server based on CentOS6.3
| |
| − | * SysVinit is no longer the default with the release of RHEL6, beyond RHEL6 systemd will be used
| |
| − | * perl has a new location of the filesystem. New: /usr/share/perl5/vendor_perl instead Old: /usr/lib/perl5/site_perl/
| |
| − | * perl version 5.8.8 is the new default version on RHEL6. This requires a review of all the perl module rpms which are specific for perl 5.8.5
| |
| − |
| |
| − | == 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
| |
| − | * Make regular snapshots of your Virtual Machine and describe them specifically. At least when you've reached an important milestone for yourself
| |
| − |
| |
| − |
| |
| − | ==== Installing the ISO ====
| |
| − | * Just install a minimal el6 installation (I just installed a few utilities like htop, screen, rsync, vim, openssh-clients mc etc…). You can use either the DVD, the minimal CD install, a net install with PXE, it's up to you
| |
| − | * wellsi: I have used CentOS-6.3-x86_64-minimal.iso
| |
| − |
| |
| − |
| |
| − | ==== 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
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | ./etc/sysconfig/network-scripts/ifup-eth eth0
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | or
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | dhclient eth0
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | <div class="mw-collapsible mw-collapsed" data-collapsetext="Collapse" data-expandtext="More on networking">
| |
| − | or if you want to assign a specific IP address (e.g. 192.168.1.2).
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | ifconfig eth0 192.168.1.2
| |
| − | echo "nameserver 192.168.1.254" >> /etc/resolv.conf
| |
| − | route add default gw 192.168.1.254 eth0
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | 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.
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | yum install nano
| |
| − | nano /etc/sysconfig/network-scripts/ifcfg-eth0
| |
| − | </syntaxhighlight>
| |
| − | and set ONBOOT=”YES”
| |
| − | </div>
| |
| − |
| |
| − | ==== Enable SSH ====
| |
| − | SSH is present but is disabled at this stage. To enable ssh issue:
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | service sshd start
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | ==== Disable SELinux ====
| |
| − | It will be easier to see what's going on (and turn off selinux at kernel level, just to be sure)
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | sed -i -e 's/rhgb quiet/selinux=0/g' /boot/grub/grub.conf
| |
| − | sed -i -e 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | ==== Remove selinux-policy-targeted and authconfig ====
| |
| − | They conflict with some e-smith/smeserver packages
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | yum remove selinux-policy-targeted authconfig
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | == Configure basic requirements ==
| |
| − | ==== Configure SME9 repositories ====
| |
| − |
| |
| − | See the following bugs tracking issues with repositories:
| |
| − | * [[bugzilla:7294|Bug #7294: rpms that still need to be rebuilt or sourced for the SME9 repositories]]
| |
| − | * [[bugzilla:7298|Bug #7298: Import perl-Unix-ConfigFile from rpmforge]]
| |
| − | * [[bugzilla:7292|Bug #7292: more rpms in the SME8 repositories that have a lower version in our SME9 repositories]]
| |
| − | * [[bugzilla:7305|Bug #7305: smeserver-yum doesn't provide the /etc/yum.smerepos.d dir]]
| |
| − |
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | yum install wget
| |
| − | </syntaxhighlight>
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | mkdir /tmp/repo.bak
| |
| − | mv /etc/yum.repos.d/*.repo /tmp/repo.bak/
| |
| − | wget -O /etc/yum.repos.d/sme9.repo http://bugs.contribs.org/attachment.cgi?id=3623
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | ==== Import needed GPG Keys ====
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | rpm --import http://sme-mirror.firewall-services.com/releases/8/smeos/x86_64/RPM-GPG-KEY-SMEServer
| |
| − | rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
| |
| − | rpm --import https://fedoraproject.org/static/217521F6.txt
| |
| − | rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
| |
| − | rpm --import http://www.salstar.sk/pub/yum/keys/RPM-GPG-KEY-Fedora-Pre-Extras
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | ==== Clean yum cache ====
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | yum clean all
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | ==== Install e-smith and smeserver packages ====
| |
| − | Now, you should be ready to install all the e-smith and smeserver packages (and their dependencies). This should pull about 400 packages
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | yum install smeserver\* e-smith\* --enablerepo=smeos8,smeupdates8
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | It should install the following packages and their dependancies. See [[#SME_Server_specific.2Frequired_packages|here]] how to retrieve a list of the required packages from an installed SME8 server.
| |
| − | e-smith
| |
| − | e-smith-LPRng
| |
| − | e-smith-apache
| |
| − | e-smith-backup
| |
| − | e-smith-devtools
| |
| − | e-smith-dynamicdns-dyndns
| |
| − | e-smith-dynamicdns-dyndns.org
| |
| − | e-smith-dynamicdns-tzo
| |
| − | e-smith-dynamicdns-yi
| |
| − | e-smith-flexbackup
| |
| − | e-smith-horde
| |
| − | e-smith-hosts
| |
| − | e-smith-imp
| |
| − | e-smith-ingo
| |
| − | e-smith-ldap

| − | e-smith-php
| |
| − | e-smith-pptpd
| |
| − | e-smith-proftpd
| |
| − | e-smith-proxy
| |
| − | e-smith-qmailanalog
| |
| − | e-smith-quota
| |
| − | e-smith-radiusd
| |
| − | e-smith-turba
| |
| − | e-smith-viewlogfiles
| |
| − | smeserver-release
| |
| − |
| |
| − | ==== Move everything from rc7.d to rc4.d ====
| |
| − | All the links in rc4.d should then point to e-smith-service
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | rm -f /etc/rc4.d/*
| |
| − | cp -a /etc/rc7.d/* /etc/rc4.d/
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | ==== Install a few missing packages ====
| |
| − |
| |
| − | See the following bugs:
| |
| − | *[[bugzilla:7233|Bug #7233: e-smith-ldap should require openldap-servers]]
| |
| − | *[[bugzilla:7252|Bug #7252: e-smith-radiusd should require freeradius-ldap]]
| |
| − | *[[bugzilla:7234|Bug #7234: e-smith-apache should require mod_ssl]]
| |
| − | *[[bugzilla:7297|Bug #7297: e-smith-hosts should require dhcp]]
| |
| − |
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | yum install mod_ssl freeradius-ldap openldap-servers dhcp
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | ==== Move some perl modules ====
| |
| − | We need to copy some perl modules to a new directory, because @INC has changed in EL6:
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | cp -a /usr/lib/perl5/site_perl/esmith/* /usr/share/perl5/vendor_perl/esmith
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | ==== Create a service entry for rsyslog ====
| |
| − | We need to create a new service entry in the DB, because the standard syslog package is now rsyslog:
| |
| − | * See [[bugzilla:7221|Bug #7221: Change from syslog to rsyslog]] and [[bugzilla:7322|Bug #7322: Change from syslog to rsyslog - Add link]] This step can be removed when e-smith-base-5.4.0-8 is available.
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | /sbin/e-smith/db configuration set rsyslog service status enabled
| |
| − | cp -a /etc/rc7.d/S05syslog /etc/rc4.d/S05rsyslog
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | ==== Run post-upgrade ====
| |
| − | We can now try to post-upgrade
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | /sbin/e-smith/signal-event post-upgrade
| |
| − | /sbin/e-smith/signal-event reboot
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | ==== The system boots but completly broken :-) ====
| |
| − | Ok, so the system should now boot, but is really not usable, after a quick look, at least the following doesn't work as expected:
| |
| − |
| |
| − | * The console on the first boot don't really work. It asks for the admin password <strike>(and BTW the password appears in cleartext)</strike> but it's all
| |
| − | * <strike>No network interfaces are detected by the console menu (because kudzu is not installed, only available in SME repo, and require an older python which conflicts with the the one * from EL6)</strike>
| |
| − | * slapd won't start
| |
| − | * httpd won't start
| |
| − | * squid won't start
| |
| − | * manually running expand-template has no effect (and no error message is printed). But signal-event seems to work (files get expanded and services restarted)
| |
| − | * as the network interface are not configured, all the services which requires the internel IP (or the external one) in their config (at least sshd squid and dnscache) won't start
| |
| − | * <strike>qpsmtpd won't start (can't locate Qpsmtpd/TcpServer.pm in @INC)</strike>
| |
| − | * There's probably a lot more which is not working
| |
| − |
| |
| − |
| |
| − | * wellsi: Is there an easy way to get SSH access to it at this point?

| |
| − | == SME Server specific/required packages ==
| |
| − | To get a list of all specific SME Server packages you can run:
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | rpm -qa | grep 'smeserver\|e-smith'| sed -e 's/-[0-9].*//' | sort > smeserver-packages.txt
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − |
| |
| − | == SME Server specific/required perl packages ==
| |
| − | To get a list of the file names ''containing'' the string 'perl' on a running SME8 server.
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | rpm -qa | grep perl | sed -e 's/-[0-9].*//' | sort
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | or, as per suggestion on the lists (All files ''starting'' with the string 'perl')
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | rpm -qa --qf '%{NAME}\n' name=perl\* | sort
| |
| − | </syntaxhighlight>
| |
| − |
| |
| − | To export the list to a plain text file you could do:
| |
| − | <syntaxhighlight lang="Bash">
| |
| − | rpm -qa | grep perl | sed -e 's/-[0-9].*//' | sort > perl-list.txt

| − | 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.
