Upgrading¶
Upgrading a Wazo is done by executing commands through a terminal on the server. You can connect to the server either through SSH or with a physical console.
To upgrade your Wazo to the latest version, you must use the wazo-upgrade
script. You can
start an upgrade with the command:
wazo-upgrade
Note
- You can’t use wazo-upgrade if you have not run the wizard yet
- Upgrading from a deprecated version is not supported.
- When upgrading Wazo, you must also upgrade all associated Wazo Clients. There is currently no retro-compatibility on older Wazo Client versions. The only exception is Wazo 16.16, which is compatible with Wazo Client 16.13.
This script will update Wazo and restart all services.
There are 2 options you can pass to wazo-upgrade:
-d
to only download packages without installing them. This will still upgrade the package containing wazo-upgrade.-f
to force upgrade, without asking for user confirmation
wazo-upgrade
uses the following environment variables:
WAZO_CONFD_PORT
to set the port used to query the HTTP API of wazo-confd (default is 9486)
Upgrade procedure¶
- Read all existing Upgrade notes starting from your version to the latest version.
- For custom setups, follow the required procedures described below (e.g. HA cluster).
- To download the packages beforehand, run
wazo-upgrade -d
. This is not mandatory, but it does not require stopping any service, so it may be useful to reduce the downtime of the server while upgrading. - When ready, run
wazo-upgrade
which will start the upgrade process. Telephony services will be stopped during the process - When finished, check that all services are running (the list is displayed at the end of the upgrade).
- Check that services are correctly working like SIP registration, ISDN link status, internal/incoming/outgoing calls, Wazo Client connections etc.
Version-specific upgrade procedures¶
Upgrading from XiVO 16.13 and before¶
When upgrading from XiVO 16.13 or before, you must use the special XiVO to Wazo upgrade
procedure instead of simply running xivo-upgrade
.
Upgrading a cluster¶
Here are the steps for upgrading a cluster, i.e. two Wazo with High Availability (HA):
On the master : deactivate the database replication by commenting the cron in
/etc/cron.d/xivo-ha-master
On the slave, deactivate the xivo-check-master-status script cronjob by commenting the line in
/etc/cron.d/xivo-ha-slave
On the slave, start the upgrade:
xivo-slave:~$ wazo-upgrade
When the slave has finished, start the upgrade on the master:
xivo-master:~$ wazo-upgrade
When done, launch the database replication manually:
xivo-master:~$ xivo-master-slave-db-replication <slave ip>
Reactivate the cronjobs (see steps 1 and 2)
Upgrading to a specific version of Wazo¶
Upgrading from i386 (32 bits) to amd64 (64 bits)¶
Unsupported versions¶
Troubleshooting¶
Postgresql¶
When upgrading Wazo, if you encounter problems related to the system locale, see PostgreSQL localization errors.
wazo-upgrade¶
If wazo-upgrade fails or aborts in mid-process, the system might end up in a faulty condition. If in doubt, run the following command to check the current state of xivo’s firewall rules:
iptables -nvL
If, among others, it displays something like the following line (notice the DROP and 5060):
0 0 DROP udp -- * * 0.0.0.0/0 0.0.0.0/0 udp dpt:5060
Then your Wazo will not be able to register any SIP phones. In this case, you must delete the DROP rules with the following command:
iptables -D INPUT -p udp --dport 5060 -j DROP
Repeat this command until no more unwanted rules are left.
