==Installing And Configuring Your SME Server Software==
The following sections explain in detail the process of installing the SME Server software.
The following sections explain in detail the process of installing the SME Server software.
{{Note box|It is recommnded that a user take note of details in the [[https://wiki.koozali.org/SME_Server:10.0#Installing | Release Notes for SME10 - Installing ]] and in particular the section covering [[https://wiki.koozali.org/index.php?title=SME_Server:10.0&mobileaction=toggle_view_desktop#Known_issues_upgrade_from_SME9 | Known Issues ]]
}}
{{Note box|If you have previously installed and configured a server and are reinstalling the software, please be aware that you should use the procedure described [[#Upgrading_From_A_Previous_Version|here]] in order to preserve your existing configuration and data. Simply performing a new installation will erase all previously existing user accounts, user directories, i-bay contents and web site and configuration parameters. If you have not already done so, you may - depending on the size of the data - wish to back up the contents of your server onto one of your desktop computers. You can do so easily by selecting "Backup or restore" from the server manager, as explained in chapter 10.1.||

When the installer sees a single disk whether on virtual or physical hardware it will not install any RAID functions for obvious reasons, but LVM will be selected: on virtual hardware you may prefer to not use LVM depending on your deployment plan. This can be specifed as shown below.

===Licensing Terms and Conditions===
In installing the SME Server software, you are agreeing to the open source licensing terms and conditions associated with it. You can read these terms and conditions in Chapter 1.2. of this guide under the title Software Licensing Terms and Conditions .

===RAID Support (Disk Mirroring and striping)===
With SME Server, you have the ability to set up disk mirroring and striping, also called RAID. In disk mirroring, your data is written to two separate hard disks installed in your server. One is the mirror of the other. Should the primary disk experience a hardware failure, the mirror disk will continue operations as if nothing had happened. All of your data will be protected from the single disk failure. This does NOT replace the need for backups! Other levels of RAID offer similar protections with more disks incorporated.

All of your data will be protected from the single disk failure. This does NOT replace the need for backups! Other levels of RAID offer similar protections with more disks incorporated.
=====Hardware RAID=====
=====Hardware RAID=====
With hardware RAID, you use a special RAID disk controller to perform the actual striping across multiple disks. As RAID is performed in hardware, the performance may be faster than software mirroring, depending on the capabilities of the various hardware. Additionally Hardware RAID can simplify configuration and array rebuilds because to the operating system, the entire RAID disk system looks like one single disk. You should be able to use any supported SATA or SCSI hardware RAID controller. NB: other options than mirroring may be supported by the controller.

<!--** If you are going to use hardware RAID, you should NOT choose Install - Dual hard disk with software RAID-1 mirroring during the installation process described in section 1.5.4. Installing the Software. (Doing so will enable software mirroring.) Instead, you should do a regular installation of the software. See [[Booting]]-->

===Upgrading From A Previous Version===
Upgrading is somewhat more complex than a clean install on a system as settings and data from the old system need to be preserved. For this reason, we start with the Upgrade procedures.

It is necessary to backup the old server and then restore to the new server. Contribs will need to be reinstalled.}}
With a physical server the simplest way to do this is via a [[SME_Server:Documentation:Administration_Manual:Chapter6#Option 8: Perform backup to USB device|Console Backup]] to a USB disk attached to the old server. Alternatively use one of the Backup & Restore options available in the Server Manager panel, i.e. backup to desktop, or backup to workstation (either to attached USB or network share). Other non-standard options exist to Backup virtual servers that do not have USB ports etc, and Restore to similar virtual systems, e.g. using SSH. Many virtual servers can also be configured to pass-through USB ports from the host to the hosted machines allowing a USB drive to be mounted, but this is an advanced topic and cannot be covered here: consult the documentation of the virtual host system in use.
{{Tip box|msg=The Restore from USB on first boot function (on a newly installed SME 10 server), will only utilise backups that are saved as smeserver.tgz files, which are the [[SME_Server:Documentation:Administration_Manual:Chapter6#Option 8: Perform backup to USB device|Console Backup]] to USB or the server manager backup to Desktop. The server manager backup to Workstation (either to USB or network share) creates a "backupdate.dar" type filename (or multiple split parts) & cannot be used to restore using the Restore on first boot function, it can only be used for restores from server manager. The new install must have its backup to workstation configured as per the old install.}}
{{Tip box|msg=The Restore from USB on first boot function (on a newly installed SME 10 server), will only utilise backups that are saved as '''smeserver.tgz''' files, which are the [[SME_Server:Documentation:Administration_Manual:Chapter6#Option 8: Perform backup to USB device|Console Backup]] to USB or the Server Manager backup to Desktop. The Server Manager "Backup to Workstation" (either to USB or network share) creates a "backupdate.dar" type filename (or multiple split parts) and cannot be used to restore using the "Restore on first boot" function, it can only be used for restores from the Server Manager. The new install must have its backup to workstation configured as per the old install.}}
{{Note box|msg=It is highly recommended that USB drives to be used for backing up '''SME 9.x''' servers prior to an upgrade to 10.n be formatted with a Linux file system. When formatting a USB to use for restore it can be type FAT or FAT32, and is preferred to be ext3 or ext4. If ext4 it should '''not''' be formatted with an OS more recent than RHEL6 for SME9; this is because ext4 has seen multiple incompatible options added with time that are not back-compatible with earlier releases. So, the simple way is to mount the USB dive to the SME 9.x server you wish to back up and format it ext 3 or 4. Ensure that is is then unmounted. The USB drive must '''not''' be mounted before running console/Server Manager backup or the backup will fail to find the drive.}}

Your SME Server needs information about your local network in order to communicate with the other computers on your network. This includes the IP address and the subnet mask on your server's internal interface. Because your server acts as a gateway and firewall, these will differ from the IP address and subnet mask on the external interface.

{{Warning box|If you configure your server in server-gateway mode make sure the IP address for the internal interface and the one for the external interface are in different ranges that do not overlap. Unless you know why you don't want to do so, it is best to use addresses from the ARIN reserved IPv4 blocks as follows:
*10.0.0.0/8 IP addresses: 10.0.0.0 – 10.255.255.255
*172.16.0.0/12 IP addresses: 172.16.0.0 – 172.31.255.255

Do please note "that only a portion of the “172” and the “192” address ranges are designated for private use. The remaining addresses are considered “public,” and thus are routable on the global Internet". The 172 block can be problematic and is perhaps best avoided.}}
If you plan to operate in server and gateway mode (explained in greater detail below), your server will act as a relay between your local network and the Internet. Because no computer on your local network, other than your server, directly interacts with the external world, the IP addresses assigned to those computers need only be unique with regards to your local network. (It doesn't matter if a computer on someone else's local network uses the same IP address, because the two machines will not be in direct contact.) As a result, we are able to use special "non-routable IP addresses" for your local network, including the internal interface of your server.
