== SME Server 9.0 on top of Scientific Linux ==

−

The installation instructions of SME Server functionality are based on minimal installation of Scientific Linux 6.3 64-bit and SME Server 9.~~0alpha1~~ repository. Please use a virtual environment to test your results. Virtual environments may include e.g. VirtualBox (free), VMWare, KVM or Xen.

The installation instructions of SME Server functionality are based on minimal installation of Scientific Linux 6.5 64-bit and SME Server 9.0 repository. Please use a virtual environment to test your results. Virtual environments may include e.g. VirtualBox (free), VMWare, KVM or Xen.

==== Install SL minimal ====

−

SME Server functionality is only tested with a minimal install of Scientific Linux. To ~~be able to~~ install 'SL minimal' one ~~must~~ use the ~~DVD~~ install ~~ISO. Other available downloads like~~ the ~~LiveCD etc~~. ~~do not have~~ the ~~option to install 'SL minimal'~~.

SME Server functionality is only tested with a minimal install of Scientific Linux. To install 'SL minimal' one can use the boot.iso. A internet connection is required. The URL required for performing a net install must point to the /pub/scientific-linux/6.5/x86_64/os/ diretory of the mirror you use.

−

You can download the SL ~~DVD install CD from either [http://ftp~~.~~scientificlinux.org/linux/scientific/6.3/x86_64/~~iso~~/SL-63-x86_64-2012-08-02-Install-DVD.iso here], [http://ftp1.scientificlinux.org/linux/scientific/6.3/x86_64/iso/SL-63-x86_64-2012-08-02-Install-DVD.iso here] or [ftp://ftp.scientificlinux.org/linux/~~scientific~~/6.3/x86_64/iso/SL-63-x86_64-2012-08-02-Install-DVD.iso here]~~. Install SL minimal in your virtual environment which should have at least:

You can download the SL boot.iso from one of the many scientific mirrors. Install SL minimal in your virtual environment which should have at least:

* 1Gb RAM memory

~~When using~~ the ~~SL install DVD you have~~ the ~~option to select what to install. Please~~ select 'minimal' and leave all other options as per their defaults.

Boot the boot.iso and follow instruction. Once the graphical installer starts, select 'minimal' and leave all other options as per their defaults.

Once the installation has finished, please reboot and continue with enabling networking and SSH.

==== Enable networking and SSH ====

−

~~Login~~ as root with the password what was provided at installation time. To enable networking please issue:

This step may not be required. Please check after login with ifconfig your networking configuration. Otherwise, login as root with the password what was provided at installation time. To enable networking please issue:

ifup eth0

−

This will bring up eth0 based on your local available DHCP server. Please check you IP with 'ipconfig' and 'ip link show'. During the configuration of SME Server functionality, final and fixed IP addresses will be configured.

service sshd start

−

~~To enable~~ SSH ~~please issue:~~

SSH will now be enabled. Please log in remotely via SSH and further instructions are based on the fact that you are remotely logged in via ssh. Specifically for Cut and Paste operations.

==== Install nano and wget ====

If you are not familiar with vi or vim, you can install the nano editor. This page assumes that you have installed nano. Please install nano and wget as follows by issuing as root on the console:

yum install nano wget

==== Disable SELinux ====

−

SELinux is enabled by default. We want to disable it for there are a few services (httpd) that get blocked by SELinux. To check ~~this~~ you can enter the command:

SELinux is enabled by default. We want to disable it for there are a few services (e.g. httpd) that get blocked by SELinux. To check the status of SELinux you can enter the command:

getenforce

−

and to disable SELinux ~~enter~~ the ~~command~~:

SELinux uses policies that conflict with some of the SME Server services ports like https. One can adjust the allowed ports, or remove the SELinux policies and disable SELinux by the following commands:

setenforce 0

sed -i -e 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config

yum remove selinux-policy-targeted

−

~~SELinux uses policies that conflict with some of the SME Server services ports like https. One can adjust the allowed ports, or remove the SELinux policies~~

−

~~yum remove selinux-policy-targeted~~

−

==== ~~Merge repo's SME and~~ SL ====

==== Update SL ====

−

~~To be able~~ to ~~download~~ the ~~required packages we need to add the SME Server repo's. The auto-selected~~ (~~closest~~) ~~mirror may not be the fastest, and you may want to hash out the 'mirrorlist=' line entries and replace them with 'baseURL=' with a repo location of your choice. Please see this the [http~~:~~//mirror.contribs.org/mirrors/ download locations overview].~~

Now is a good time to update your SL installation with the latest (security) updates:

yum update

−

==== ~~Yum install~~ ====

==== Add SME Server repo ====

−

~~<nowiki>~~

To be able to download the required packages we need to add the SME Server repo:

−

yum install e-smith\* smeserver\* aspell aspell-en at audit-libs-python autoconf automake bc bind-libs bind-utils cronie cronie-anacron crontabs cyrus-sasl-md5 dhcp dosfstools ed eject elfutils elfutils-libs fetchmail ftp gettext glib gpm hesiod hmaccalc imake iptraf iptstate isdn4k-utils libXdmcp libgomp libselinux-python libsmbclient libsysfs libxml2-python lm_sensors lockdev lsof lvm2 m2crypto man mcstrans minicom mkbootdisk mlocate mod_ssl mtools mt-st mutt neon net-snmp net-snmp-utils openldap-servers patch pcmciautils postgresql-libs pyxf86config rpm-build rp-pppoe setserial strace sudo sysfsutils syslinux tcpdump telnet time tmpwatch traceroute unzip usbutils usermode vim-common vim-enhanced wget wodim xz zip zlib php-pear-Net-URL perl-Compress-Raw-Bzip2 perl-IO-Compress-Bzip2 rsync tnef freeradius-ldap --exclude=centos*,smeserver-release --nogpg

nano -w /etc/yum.repos.d/smeos9.repo

−

</~~nowiki>~~

−

~~Install 497 Package(s)~~

and paste the following into it:

−

~~Upgrade 19 Package(s)~~

−

~~Total download size~~: ~~226 M~~

−

==== ~~Yum update~~ ====

[smeos9]

−

~~After the initial yum install we need to update to the latest versions available in the repositories~~.

enabled=1

MirrorList=http://mirrorlist.contribs.org/mirrorlist/smeos-9

name=SME Server9 - os

enablegroups=1

gpgcheck=1

includepkgs = e-smith\* smeserver\* *.sme.* clamav* clamd* *dar mod_authnz* mhash tbb perl-* htop proftpd php-pear-* GeoIP mod_auth_tkt radiusclient-ng nut-client nut pyzor oidentd rssh pam_abl clamav par2cmdline DCC wv checkpassword pam pv razor-agents clam-db initscripts checkpassword-pam

−

~~yum update --nogpg~~

Now we can install the required packages from the repo's. The ''includepkgs'' line in the SME Server repo file ensure that '''only''' the required packages for SME Server will come from the SME repo's, and all others from the sl repo's.

yum install e-smith\* smeserver\* *.sme.* initscripts --exclude=smeserver-release*,*86 --nogpg

−

This will result in the ~~below~~ summary. The numbers may vary depending on the changes in the repositories.

This will result in the following summary. The numbers may vary depending on the changes in the repositories.

After yum is finished and all packages are installed, we can remove the temporary /etc/yum.repos.d/smeos9.repo file:

rm -f /etc/yum.repos.d/smeos9.repo

==== Post-upgrade/reboot ====

Line 88: Line 96:

/sbin/e-smith/signal-event post-upgrade

/sbin/e-smith/signal-event reboot

{{note box | Please note that as of this point SME Server functionality is in place and in control. This means that your normal admin tasks have to be adapted to the SME Server principales described in the [[SME_Server:Documentation:Administration_Manual|Administration Manual]].}}

== First use ==

==== Set root password ====

After the first boot, there is the opportunity to restore from a backup and a new root (admin) password will be asked. This may be the same as you used for the initial installation of SL or you can set a new one. After setting the root password, SME Server will configure additional settings and automatically reboot.

−

==== ~~First use~~ ====

==== Configuration ====

−

* Set admin password

When the system has rebooted, it is ready for SME Server configuration of network and services settings. To start this process, please login as root and type:

−

* autoreboot

console

−

* console

−

* reboot

and select 'configure this server'. After configuration, the server will reboot itself, re-configure itself based on the user choices and is in full operational mode ready for full use.

−

* Adjust yum repositories (add SL ~~and~~ remove ~~centos)~~

After the reboot, you can access the server-manager (https://your_ip/server-manager) and login as admin and the root password. In server-manager one can enable ssh and set various ssh options.

==== Adjust yum repositories ====

By default SME Server assumes it has CentOS as base linux system, In this case we use Scientific Linux, so we have to remove the CentOS specific repo's and add the SL repo's.

NOTES:

* The default SME Server repo's are part of sme-base

* The default (CentOS) repo's get re-initialized on yum-update

* so..... with an update of sme-base or a post-install, the repo's turn back to SME defaults

To remove the CentOS specific repo's issue the following commands as root:

db yum_repositories delete base

db yum_repositories delete addons

Line 101: Line 129:

db yum_repositories delete contrib

db yum_repositories delete extras

db yum_repositories delete fasttrack

db yum_repositories delete updates

and update the yum repositories db

signal-event yum-modify

Now we need to configure the SME repo's to *only* include SME Specific packages or packages that are not available in the SL repo's, and we need to configure the SL repo's the SME Server way.

Add SL repo's the 'SME Server way'

TBA

and update and activate the revised yum repo's configuration with the following command:

signal-event yum-modify

== Current status ==

The above instructions should have brought you 'on par' with SME Server 9.0
