Upgrading your SIPIS installation¶
We recommend that you create a full backup of your SIPIS machine regularly. When doing SIPIS upgrades (or when moving SIPIS to a different machine) your backup needs to include at least the following items:
- Files from
- Your TLS certificates and keys.
sipisdatabase (it is unusable without
- Your username and password for Acrobits’ repository (however, you can get a new one from Acrobits).
Configuration files version¶
Occassionally we make changes to a default configuration file. In that case the upgrade process will ask you if you want to replace the configuration file by the new version. This is Debian’s package manager asking you. If this happens, you should answer No so that you keep your currently-installed version.
New version from the package will be installled with the suffix
.dpkg-dist. If you answered Yes, your version will be renamed by adding suffix
.dpkg-old. In both cases you should check the differences between the old and new version to decide what settings you think are best for you.
If you answer Yes you may get an error saying
FATAL: password authentication failed for user "sipis". While it may
sound scary, it just means that our script could not connect to your
Settings.xml file and run
Regular upgrading means upgrading without moving between Debian versions. This upgrade is usually as simple as running
apt-get update && apt-get upgrade
The upgrade will stop SIPIS server, install a new version and start it again.
This upgrades all Debian packages. If you want to upgrade only SIPIS, run
apt-get update && apt-get install sipis.
Make sure that you have only this server set up as NotificationServer in your Settings.xml file:
<NotificationServer Name="*" Host="pnm.cloudsoftphone.com" Port="6552" Premium="No" RequiresTls="Yes" />
Migrating to a different server¶
Migrating SIPIS installation to a different machine is fairly straightforward procedure.
- Do a clean installation of SIPIS on the target machine.
- Stop SIPIS on both source and target machines.
- Move the database between the machines: that means dropping the database on the new server (if you created it), and importing the database from the old server.
- Copy contents of /etc/sipis to the new server (replacing ones from the installation).
Upgrading to Debian 9 – Stretch¶
We replaced the parts of SIPIS infrastructure in the new version of SIPIS for Debian 9 Stretch. The upgrade to new Debian version (and new versions of SIPIS) requires several manual steps. We assume that you are running Debian 8 Jessie which hosts only SIPIS installed using our installation guide and no other service. Even if that is not the case, you or your system administrator should be able to use this guide to do the upgrade.
If you want to use new SIPIS in Debian 8 Jessie, you can use SIPIS from our Stretch repository. In the first step change only Acrobits.list file and skip step 5 (upgrading postgres database). We did not push these updates to Jessie repository because they require manual changes to configuration.
Update addresses to Debian repositories. In the files
/etc/apt/sources.list(this is for Debian upgrade) and
/etc/apt/sources.list.d/Acrobits.list(this is for SIPIS upgrade) replace every occurence of
stretch. For example the Acrobits.list file should now read.
deb http://username:firstname.lastname@example.org/debian stretch main
These packages will work also on Debian 10 Buster.
apt-get update apt-get dist-upgrade
This will install a new version of Debian and new version of SIPIS package. However, there are more steps that need to be done.
- Install our new package named
loadbalancer2that will replace
apt-get install loadbalancer2
Remove file /etc/stunnel/tcpudpbridge.conf if it exists (if you are using TLS).
(optional) Upgrade postgresql database from 9.4 (default in Debian 8 Jessie) to 9.6 (default in Debian 9 Stretch).
If you do not fully understand this step, skip it. This step may cause you to lose data. Your sipis should still work without this.
The following three commands will upgrade postgreql database. Replace
OLDVERSION with appropriate version (9.4 and 9.6 for upgrade from Debian 8 to Debian 9).
pg_dropcluster --stop NEWVERSION main pg_upgradecluster OLDVERSION main pg_dropcluster OLDVERSION main
/etc/sipis/Settings.xmlfile and change Server Port from 4998 to 14998 (do NOT change
Nameparameter) For example:
<Server Name="SipisOne" Address="0.0.0.0" Port="14998" />
If you use TLS, edit file
- Provide path to Certificate and PrivateKey.
Certificate and PrivateKey must be readable by user
Enable start of LoadBalancer2:
systemctl enable LoadBalancer2.service
Reboot the machine
