Upgrade Lizmap Web Client

Upgrading from Lizmap 2.x

Upgrading from Lizmap 3.x versions

From 3.0 versions to upper, here is how to upgrade.

Data backup

Backup your data into a directory (ex: /tmp) with the lizmap/install/backup.sh script, so you could reinstall them if the installation failed.

lizmap/install/backup.sh /tmp

If you want to backup by hand, you should backup at least these files:

var/db/jauth.db
var/db/logs.db
var/config/installer.ini.php
var/config/liveConfig.ini.php (if it exists)
var/config/lizmapConfig.ini.php
var/config/localconfig.ini.php
var/config/profiles.ini.php

Replace Lizmap files

Get the Lizmap archive by downloading an archive on the release page.

You should then :

replace the lib/ directory by the new lib/ directory
replace files into lizmap/ directory by the new lizmap/ files
If the replacement has erased some files that you haven’t done any backup before, restore them with lizmap/install/restore.sh /tmp

Launch the installer

You have to launch the installer, it will upgrade some stuff: database tables, configuration etc..

sudo lizmap/install/clean_vartmp.sh
php lizmap/install/installer.php
sudo lizmap/install/clean_vartmp.sh

Nota

if you upgrade from 3.0 or 3.1 to Lizmap 3.2/3.3, and if you are using the ldap authentication with the ldapdao module, you have to know that this module is included into Lizmap 3.2/3.3 and is pre-configured. So, before launching the installer, you have to remove the ldapdao module you’ve installed, and you have to configure the ldapdao module in a little different manner than when installing it by hand. See the ldap configuration section in this manual.

Delete Jelix temporary files

rm -rf /var/www/$MYAPP-$VERSION/temp/lizmap/*

Redefine the rights to the application files

cd /var/www/$MYAPP-$VERSION
chown :www-data temp/ lizmap/var/ lizmap/www lizmap/install/qgis/edition/ -R
chmod 775 temp/ lizmap/var/ lizmap/www lizmap/install/qgis/edition/ -R

Migrating from Sqlite to Postgresql

You may have installed Lizmap with Sqlite. You should then have these files lizmap/var/db/jauth.db and lizmap/var/db/logs.db, where some data like users, permissions and logs are stored. And you should have this configuration into lizmap/var/config/profiles.ini.php:

[jdb:jauth]
driver=sqlite3
database="var:db/jauth.db"

[jdb:lizlog]
driver=sqlite3
database="var:db/logs.db"

It you have a such configuration, you can migrate data to a Postgresql database.

First, create a Postgresql database, and then change the configuration into lizmap/var/config/profiles.ini.php, by setting access parameters to the Postgresql database. It is recommended to create a schema into the database, for example lizmap , if it contains already some tables.

For example :

[jdb:jauth]
driver=pgsql
host=localhost
port=5432
database="your_database"
user=my_login
password=my_password
search_path=lizmap,public

[jdb:lizlog]
driver=pgsql
host=localhost
port=5432
database="your_database"
user=my_login
password=my_password
search_path=lizmap,public

See the chapter about installation to know more about these parameters.

Then you can launch these scripts which will migrate the data.

php lizmap/scripts/script.php lizmap~database:migrateusers
php lizmap/scripts/script.php lizmap~database:migratelog

If there are no errors, you can then go onto lizmap with your browser, and check that you can authenticate yourself. You should see also the list of users into the administration panel. If this is the case, you can backup files jauth.db and logs.db and you can delete them.

If something goes wrong and you cannot fix the issue, revert the database access into lizmap/var/config/profiles.ini.php as before, like this :

[jdb:jauth]
driver=sqlite3
database="var:db/jauth.db"

[jdb:lizlog]
driver=sqlite3
database="var:db/logs.db"

And Lizmap should work well, but still with Sqlite.
