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:

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

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

Servidor FTP: pure-ftpd

Nota

Esta secção é opcional

Instalar

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

Configurar

# 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
echo "133 022" > /etc/pure-ftpd/conf/Umask
# The port range for passive mode (opening outwards)
echo "5400 5600" > /etc/pure-ftpd/conf/PassivePortRange
# Creating an SSL certificate for FTP
openssl req -x509 -nodes -newkey rsa:1024 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem
chmod 400 /etc/ssl/private/pure-ftpd.pem
# Restart FTP server
service pure-ftpd restart

Criar uma conta de utilizador

# Creating a user accountr
MYUSER=demo
useradd -g client -d /home/data/ftp/$MYUSER -s /bin/ftponly -m $MYUSER -k /home/data/ftp/template/
passwd $MYUSER
# Fix the user's FTP root
chmod a-w /home/data/ftp/$MYUSER
# Creating empty directories that will be the future Lizmap Web Client directories
mkdir /home/data/ftp/$MYUSER/qgis/rep1 && chown $MYUSER:client /home/data/ftp/$MYUSER/qgis/rep1
mkdir /home/data/ftp/$MYUSER/qgis/rep2 && chown $MYUSER:client /home/data/ftp/$MYUSER/qgis/rep2
mkdir /home/data/ftp/$MYUSER/qgis/rep3 && chown $MYUSER:client /home/data/ftp/$MYUSER/qgis/rep3

mkdir /home/data/ftp/$MYUSER/qgis/rep5 && chown $MYUSER:client /home/data/ftp/$MYUSER/qgis/rep5
# Create a directory to store the cached server
mkdir /home/data/cache/$MYUSER
chmod 700 /home/data/cache/$MYUSER -R
chown www-data:www-data /home/data/cache/$MYUSER -R

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

Retrieve and install Lizmap Web Client

cd /var/www/

Com um ficheiro ZIP

Retrieve the latest available stable version from https://github.com/3liz/lizmap-web-client/releases/

cd /var/www/
# Options
VERSION=3.3.0
# Archive recovery with wget
wget https://github.com/3liz/lizmap-web-client/releases/download/$VERSION/lizmap-web-client-$VERSION.zip
# Unzip archive
unzip $VERSION.zip
# virtual link for http://localhost/lizmap/
ln -s /var/www/lizmap-web-client-$VERSION/lizmap/www/ /var/www/html/lizmap
# Remove archive
rm $VERSION.zip

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:

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

Development version with git

Aviso

A versão de desenvolvimento está frequentemente a sofrer alterações, devido a isso podem ocorrer alguns bugs. Não a utilize em ambiente de produção.

  • The first time

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
  • Para atualizar sua versão a partir do repositório principal

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

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:

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

E também a partir do 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&

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.
