Installing Lizmap Web Client on Linux Debian or Ubuntu

Примечание

If you want to quickly install and test Lizmap Web Client in a few steps, you can follow those instructions.

Generic Server Configuration with Nginx server

This documentation provides an example for configuring a server with the Debian 9 distribution. We assume you have base system installed and updated.

Предупреждение

This page does not describe how to secure your Nginx server. It’s just for a demonstration.

Configure Locales

For simplicity, it is interesting to configure the server with UTF-8 default encoding.

# configure locales
locale-gen fr_FR.UTF-8 #replace fr with your language
dpkg-reconfigure locales
# define your timezone [useful for logs]
dpkg-reconfigure tzdata
apt install ntp ntpdate

Примечание

It is also necessary configure the other software so that they are using this default encoding if this is not the case.

Installing necessary packages

Предупреждение

Lizmap web client is based on Jelix 1.6. You must install at least the 5.6 version of PHP. The dom, simplexml, pcre, session, tokenizer and spl extensions are required (they are generally turned on in a standard PHP 5.6/7.x installation)

sudo su # only necessary if you are not logged in as root
apt update # update package lists
apt-get install curl openssl libssl1.1 nginx-full nginx nginx-common

On debian 10, install these packages:

apt-get install php7.3-fpm php7.3-cli php7.3-bz2 php7.3-curl php7.3-gd php7.3-intl php7.3-json php7.3-mbstring php7.3-pgsql php7.3-sqlite3 php7.3-xml php7.3-ldap

On Ubuntu 18.04 or later, install these packages:

apt-get install php7.3-fpm php7.3-cli php7.3-bz2 php7.3-curl php7.3-gd php7.3-intl php7.3-json php7.3-mbstring php7.3-pgsql php7.3-sqlite3 php7.3-xml php7.3-ldap

Web configuration

Create a new file /etc/nginx/sites-available/lizmap.conf:

server {
    listen 80;

    server_name localhost;
    root /var/www/html/lizmap;
    index index.php index.html index.htm;

    # compression setting
    gzip_vary on;
    gzip_proxied any;
    gzip_comp_level 5;
    gzip_min_length 100;
    gzip_http_version 1.1;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript text/json;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ [^/]\.php(/|$) {
       fastcgi_split_path_info ^(.+\.php)(/.*)$;
       set $path_info $fastcgi_path_info; # because of bug http://trac.nginx.org/nginx/ticket/321
       try_files $fastcgi_script_name =404;
       include fastcgi_params;

       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       fastcgi_param PATH_INFO $path_info;
       fastcgi_param PATH_TRANSLATED $document_root$path_info;
       fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
       fastcgi_param SERVER_NAME $http_host;
    }
}

You should declare the lizmap.local domain name somewhere (in your /etc/hosts, or into your DNS..), or replace it by your own domain name.

Enable the virtual host you just created:

ln -s /etc/nginx/sites-available/lizmap.conf /etc/nginx/sites-enabled/lizmap.conf

Generic Server Configuration with Apache2 server

To install QGIS-server on apache refer to the official QGIS documentation https://docs.qgis.org/latest/en/docs/server_manual/index.html

Installing necessary packages

Предупреждение

Lizmap web client is based on Jelix 1.6. You must install at least the 5.4 version of PHP. The dom, simplexml, pcre, session, tokenizer and spl extensions are required (they are generally turned on in a standard PHP 5.4 installation)

Примечание

At least the current version supports PHP 7, so it should be straight forward to install it on current debian 9 or ubuntu 16.04.

sudo su # only necessary if you are not logged in as root
apt update # update package lists

On debian 10, install these packages:

apt install php7.3-fpm php7.3-cli php7.3-bz2 php7.3-curl php7.3-gd php7.3-intl php7.3-json php7.3-mbstring php7.3-pgsql php7.3-sqlite3 php7.3-xml php7.3-ldap

On Ubuntu 18.04 LTS

apt install xauth htop curl libapache2-mod-fcgid libapache2-mod-php7.3 php7.3-cgi php7.3-gd php7.3-sqlite php7.3-curl php7.3-xmlrpc python-simplejson software-properties-common

Enable geolocation

The automatic geolocation provided by Lizmap relies on Google services. To enable it, your webGIS must be placed under a secure protocol, like HTTPS. See for more details:

https://sites.google.com/a/chromium.org/dev/Home/chromium-security/deprecating-powerful-features-on-insecure-origins

https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-apache-in-ubuntu-16-04

Restart Nginx

You must restart the Nginx server to validate the configuration.

service nginx restart

Create directories for data

QGIS files and other cache files will be stored into these directories.

 mkdir /home/data
 mkdir /home/data/cache/
# optional
 mkdir /home/data/ftp
 mkdir /home/data/ftp/template/
 mkdir /home/data/ftp/template/qgis

Spatial Database: PostgreSQL

Примечание

This section is optional, but required if you want to enable editing capabilities on a layer. See Prerequisites.

PostgreSQL and PostGIS can be very useful to manage spatial data centralized manner on the server.

Install

# Install packages
apt-get install postgresql postgresql-contrib postgis pgtune

# A cluster is created in order to specify the storage directory
mkdir /home/data/postgresql
service postgresql stop
pg_dropcluster --stop 9.6 main
chown postgres:postgres /home/data/postgresql
pg_createcluster 9.6 main -d /home/data/postgresql --locale fr_FR.UTF8 -p 5678 --start

# Creating a "superuser" user
su - postgres
createuser myuser --superuser
# Modifying passwords
psql
ALTER USER postgres WITH ENCRYPTED PASSWORD '************';
ALTER USER myuser WITH ENCRYPTED PASSWORD '************';
\q
exit

Adapting the PostgreSQL configuration

We will use pgtune, an utility program that can automatically generate a PostgreSQL configuration file adapted to the properties of the server (memory, processors, etc.)

# PostgreSQL Tuning with pgtune
pgtune -i /etc/postgresql/9.6/main/postgresql.conf -o /etc/postgresql/9.6/main/postgresql.conf.pgtune --type Web
cp /etc/postgresql/9.6/main/postgresql.conf /etc/postgresql/9.6/main/postgresql.conf.backup
cp /etc/postgresql/9.6/main/postgresql.conf.pgtune /etc/postgresql/9.6/main/postgresql.conf
nano /etc/postgresql/9.6/main/postgresql.conf
# Restart to check any problems
service postgresql restart
# If error messages, increase the linux kernel configuration variables
echo "kernel.shmall = 4294967296" >> /etc/sysctl.conf # to increas shred buffer param in kernel
echo "kernel.shmmax = 4294967296" >> /etc/sysctl.conf
echo 4294967296 > /proc/sys/kernel/shmall
echo 4294967296 > /proc/sys/kernel/shmmax
sysctl -a | sort | grep shm
# Restart PostgreSQL
service postgresql restart

FTP Server: pure-ftpd

Примечание

This section is optional

Install

apt-get install pure-ftpd pure-ftpd-common

Configure

# Creating an empty shell for users
ln /bin/false /bin/ftponly
# Configuring FTP server
echo "/bin/ftponly" >> /etc/shells
# Each user is locked in his home
echo "yes" > /etc/pure-ftpd/conf/ChrootEveryone
# Allow to use secure FTP over SSL
echo "1" > /etc/pure-ftpd/conf/TLS
# Configure the properties of directories and files created by users

Development version with Git

Предупреждение

The development version is always changing, and bugs can occur. Do not use it in production.

Предупреждение

Using the code from GIT, either from the git clone or the automatic ZIP created by GitHub on-the-fly, needs to build the package first. It is not possible to use this code directly. If you don’t want to build, you must use some Lizmap Web Client ZIP packages which are ready to be installed, as written in the step before.

  • First installation

The source code in the Git repository is missing external PHP and Javascript packages. In order to install and build some files, you need to install PHP Composer, NodeJs and Npm, as well as some other tools like Make. Read the CONTRIBUTING.md file, provided with the source code, to have details about how to install these tools and to build the package.

apt-get install git
cd /var/www/
VERSION=master
# Clone the master branch
git clone https://github.com/3liz/lizmap-web-client.git lizmap-web-client-$VERSION
# Go into the git repository
cd lizmap-web-client-$VERSION
# Create a personal branch for your changes
git checkout -b mybranch
# Launch PHP Composer, Npm etc, to install external dependencies
make build
  • To update your branch from the master repository

cd /var/www/lizmap-web-client-$VERSION
# Check that you are on the branch: mybranch
git checkout mybranch

# If you have any changes, make a commit
git status
git commit -am "Your commit message"

# Save your configuration files!
lizmap/install/backup.sh /tmp

# Update your master branch
git checkout master && git fetch origin && git merge origin/master
# Apply to your branch, marge and manage potential conflicts
git checkout mybranch && git merge master
# Apply rights
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

You should then update dependencies (like external PHP and javascript packages). See the CONTRIBUTING.md file provided with the source code.

Примечание

It is always good to make a backup before updating.

Configure Lizmap with the database support

Lizmap needs a database to store its own data and to access to data used in your Qgis projects, with its editing tool.

Create profiles.ini.php into lizmap/var/config by copying profiles.ini.php.dist.

cd lizmap/var/config
cp profiles.ini.php.dist profiles.ini.php
cd ../../..

PostgreSQL

For the editing of PostGIS layers in Web Client Lizmap operate, install PostgreSQL support for PHP.

sudo apt-get install php7.3-pgsql
sudo service nginx restart

Into a fresh copy of lizmap/var/config/profiles.ini.php, you should have:

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

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

This is the configuration by default to use Sqlite. You should change these sections to use Postgresql, and indicate several parameters to access to your Postgresql database:

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

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

You can use a specific schema to store lizmap tables. And you may want that lizmap could access to other schema. You then have to set search_path correctly. Example:

search_path=lizmap,my_schema,public

If you have setup a service file for postgresql onto your server, you may want to indicate a postgresql service instead of indicating login, password and so on. Use then the service parameter:

[jdb:jauth]
driver=pgsql
service=my_service
database="your_database"
search_path=lizmap,public

[jdb:lizlog]
driver=pgsql
service=my_service
database="your_database"
search_path=lizmap,public

Spatialite

Enable Spatialite extension

To use editing on layers spatialite,you have to add the spatialite extension in PHP. You can follow these instructions to do so: http://www.gaia-gis.it/gaia-sins/spatialite-cookbook-fr/html/php.html

Lizmap Web Client tests whether the spatialite support is enabled in PHP. If it is not, then spatialite layers will not be used in the editing tool. You can always use PostgreSQL data for editing.

Give the appropriate rights to the directory containing Spatialite databases

So that Lizmap Web Client can modify the data contained in databases Spatialite, we must ensure that the webserver user (www-data) has well write access to the directory containing each Spatialite file

For example, if a directory contains a QGIS project, which uses a Spatialite database placed in a db directory at the same level as the QGIS project:

/path/to/a/lizmap_directory
|--- mon_projet.qgs
|--- bdd
   |--- my_spatialite_file.sqlite

So you have to give the rights in this way:

chown :www-data /path/to/a/lizmap_directory -R
chmod 775 /path/to/a/lizmap_directory -R

Примечание

So if you want to install Lizmap to provide access to multiple map publishers, you should tell them to always create a db directory at the same level as the QGIS projects in the Lizmap Web Client directory. This will facilitate the admin work that just have to change the rights of this unique directory.

Configuring Lizmap and launching the installer

Give the appropriate rights to directories and files

Set rights for Nginx/Apache, so php scripts could write some temporary files or do changes.

cd /var/www/lizmap-web-client-$VERSION/
lizmap/install/set_rights.sh www-data www-data
chown :www-data lizmap/install/qgis/edition/ -R
chmod 775 lizmap/install/qgis/edition/ -R

Setup configuration

Create lizmapConfig.ini.php, localconfig.ini.php and edit them to set parameters specific to your installation. You can modify lizmapConfig.ini.php to set the url of qgis map server and other things.

cd lizmap/var/config
cp lizmapConfig.ini.php.dist lizmapConfig.ini.php
cp localconfig.ini.php.dist localconfig.ini.php
cd ../../..

In case you want to enable the demo repositories, just add to localconfig.ini.php the following:

[modules]
lizmap.installparam=demo

Launching the installer

After creating configuration files, you can launch the installer

php lizmap/install/installer.php

It will finished the installation, and will create all SQL tables needed by Lizmap.

First test

For testing launch: http://localhost/lizmap in your browser.

In case you get a 500 - internal server error, run again:

cd /var/www/lizmap-web-client-$VERSION/
lizmap/install/set_rights.sh www-data www-data

Примечание

Replace localhost with the address or IP number of your server.

In the administration panel, you should check the QGIS server version and the WMS server URL with the URL of QGIS Server.

If you didn’t install the demo, you can check that you have well installed Lizmap and configured QGIS Server within Lizmap by checking the qgis_server section in this URL: http://localhost/lizmap/index.php/view/app/metadata

{
    "qgis_server":{
        "test":"OK",
        "mime_type":"text\/xml; charset=utf-8"
    }
}

Lizmap is accessible, without further configurations, also as WMS and WFS server from a browser:

http://localhost/lizmap/index.php/lizmap/service/?repository=montpellier&project=montpellier&VERSION=1.3.0&SERVICE=WMS&REQUEST=GetCapabilities

http://localhost/lizmap/index.php/lizmap/service/?repository=montpellier&project=montpellier&SERVICE=WFS&REQUEST=GetCapabilities

and from QGIS:

http://localhost/lizmap/index.php/lizmap/service/?repository=montpellier&project=montpellier&VERSION=1.3.0&

http://localhost/lizmap/index.php/lizmap/service/?repository=montpellier&project=montpellier&

Примечание

Access to the WMS and WFS servers can be limited by assigning privileges to specific repositories, see the administration section.

Lizmap modules

Previously, we explained how we could add QGIS Server plugins to add more features to QGIS Server. Now that we have Lizmap Web Client up and running, we can add some Lizmap modules to add again some features.

The list is available in the Lizmap introduction. On their GitHub repository, their is usually their install instructions. You should follow them. However here are the main instructions to install a module.

Installing modules with Composer

You can install modules with Composer, the package manager for PHP. Of course it is possible only if the author of the module has created a package of his module. A such package has a name, for example lizmap/lizmap-pgmetadata-module`. The documentation of the module should indicate it.

You must install Composer. See instructions on its web site http://getcomposer.org.

You must create a composer.json file into lizmap/my-packages/ by copying the composer.json.dist from this directory. And launching a first time Compose

cp -n lizmap/my-packages/composer.json.dist lizmap/my-packages/composer.json
composer install --working-dir=lizmap/my-packages

Then you can install the package of the module

composer require --working-dir=lizmap/my-packages "lizmap/lizmap-pgmetadata-module"

If you want to install a new version of the module, just execute:

composer update --working-dir=lizmap/my-packages

Read the documentation of the module to know if there are additional steps to configure it.

To finish the installation, run again the installer of Lizmap:

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

installing modules without Composer

To install a module without Composer, retrieve the zip file of the module.

  • Extract the module into lizmap/lizmap-modules/. For instance, for the module PgMetadata :

$ ls -hl lizmap/lizmap-modules/pgmetadata/
total 44K
drwxrwxr-x 2 etienne etienne 4,0K nov.  17 12:38 classes
drwxrwxr-x 2 etienne etienne 4,0K nov.   4 12:50 controllers

-rw-rw-r-- 1 etienne etienne  146 nov.   4 10:38 events.xml
drwxrwxr-x 2 etienne etienne 4,0K nov.   4 10:09 forms
drwxrwxr-x 2 etienne etienne 4,0K nov.   4 12:50 install
drwxrwxr-x 4 etienne etienne 4,0K nov.   4 10:09 locales

drwxrwxr-x 2 etienne etienne 4,0K nov.  17 12:38 www
  • Edit the lizmap/var/config/localconfig.ini.php, in the modules section, add a new line for the given module (check the documentation of the module to setup the correct values):

[modules]
pgmetadata.access=2
  • Read the documentation of the module to know if there are additional steps to configure it.

  • Run the installation :

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