Instalação do Lizmap Web Client em Linux Debian ou Ubuntu
Generic Server Configuration
This documentation provides an example for configuring a server with the Debian 9 distribution. We assume you have base system installed and updated.
Aviso
This page does not describe how to secure your Nginx server. It’s just for a demonstration.
Configurar Idiomas
Para simplificar, é importante configurar o servidor com a codificação padrão UTF-8.
# 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
Nota
Também é necessário configurar outro software para que o mesmo passe a utilizar esta codificação padrão, se não for esse o caso.
Instalação dos pacotes necessários
Aviso
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)
On debian 9, install these packages:
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
apt-get install php7.0-fpm php7.0-cli php7.0-bz2 php7.0-curl php7.0-gd php7.0-intl php7.0-json php7.0-mbstring php7.0-pgsql php7.0-sqlite3 php7.0-xml php7.0-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/php7.0-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
Ativar a geolocalização
A geolocalização automática fornecida pelo Lizmap depende dos serviços da Google. Para ativação da mesma o site webGIS deve ser colocado sob um protocolo seguro, como o HTTPS. Para mais detalhes ver:
Restart Nginx
You must restart the Nginx server to validate the configuration.
service nginx restart
Criar diretórios para os dados
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 DBMS: PostgreSQL
Nota
Esta secção é opcional
PostgreSQL e PostGIS podem ser muito úteis para a gestão de dados espaciais de forma centralizada no servidor.
Instalar
# 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
Adaptação da configuração do PostgreSQL
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

Map server: QGIS Server
Nota
Details for the installation may differ for specific versions of the operating system. Please refer to http://qgis.org/en/site/forusers/download.html for up to date documentation.
First declare the QGIS repository into a /etc/apt/sources.list.d/debian-qgis.list file. Its content should be:
deb http://qgis.org/debian-ltr stretch main
Install also the Qgis key for the package manager
# Add keys
sudo gpg --recv-key CAEB3DC3BDF7FB45
sudo gpg --export --armor CAEB3DC3BDF7FB45 | sudo apt-key add -
Update the package repository and install the Qgis packages:
# Update package list
sudo apt-get update
# Install QGIS Server
sudo apt-get install qgis-server python-qgis
Nota
See https://docs.qgis.org/testing/en/docs/user_manual/working_with_ogc/server/index.html for more information on QGIS Server.

Set rights for Nginx, 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
Create lizmapConfig.ini.php, localconfig.ini.php and profiles.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, and profiles.ini.php to store data in a database other than an sqlite database.
cd lizmap/var/config
cp lizmapConfig.ini.php.dist lizmapConfig.ini.php
cp localconfig.ini.php.dist localconfig.ini.php
cp profiles.ini.php.dist profiles.ini.php
cd ../../..
In case you want to enable the demo repositories, just add to localconfig.ini.php the following:
[modules]
lizmap.installparam=demo
Then you can launch the installer
php lizmap/install/installer.php
For testing launch: http://127.0.0.1/lizmap in your browser.
Caso apareça a mensagem 500 - internal server error, execute novamente o instalador:

# 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
Nota
É sempre bom fazer um backup antes de atualizar.
Atribua as permissões apropriadas aos diretórios e ficheiros
cd /var/www/lizmap-web-client-$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
Primeiro teste
Go to the Lizmap Web Client home to see if the installation was performed correctly: http://localhost/lizmap
Nota
Substitua localhost pelo endereço IP do seu servidor.
O Lizmap deverá estar também acessível, sem configurações adicionais, como servidores WMS e WFS a partir de um navegador:
E também a partir do QGIS:
http://localhost/lizmap/index.php/lizmap/service/?repository=montpellier&project=montpellier&
Nota
O acesso aos servidores WMS e WFS pode ser limitado pela atribuição de privilégios a repositórios específicos, consulte a secção de administração.
Editing tool: Configure the server with the database support
Nota
Esta secção é opcional
PostgreSQL
Para a edição de camadas PostGIS funcionar no Lizmap Web Client, instale o suporte PostgreSQL para PHP.
sudo apt-get install php7.0-pgsql
sudo service nginx restart
Nota
Para edição, é altamente recomendável utilizar uma base de dados PostgreSQL. Isso simplifica muito a instalação e recuperação de dados introduzidos pelos utilizadores.
Spatialite
Ativar a extensão Spatialite
To use editing on layers spatiatlite,you have to add the spatialite extension in PHP. You can follow these instructions to do so: http://www.gaia-gis.it/spatialite-2.4.0-4/splite-php.html
Lizmap Web Client tests whether the spatialite support is enabled in PHP. If it is not, then spatialities layers will not be used in the editing tool. You can always use PostgreSQL data for editing.
Atribua as permissões apropriadas ao diretório que contém as bases de dados Spatialite
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
Por exemplo, se um diretório contém um projeto QGIS, que utiliza uma base de dados Spatialite colocada num diretório db no mesmo nível do projeto QGIS:
/path/to/a/lizmap_directory
|--- mon_projet.qgs
|--- bdd
|--- my_spatialite_file.sqlite
Então terá que atribuir as permissões desta forma:
chown :www-data /path/to/a/lizmap_directory -R
chmod 775 /path/to/a/lizmap_directory -R
Nota
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.
