Servizi

Per configurare Servizi, fai clic sul pulsante Modifica sotto il riepilogo.

Avvertimento

QGIS Server deve essere installato nello stesso computer di Lizmap Web Client

  • WMS subdomain URLs list (optional): The use of multiple domain names is one of the classic optimizations when a web application uses OpenLayers (as Lizmap Web Client). You can enter a list of subdomains separated by comma.

    • You must use a list of subdomains relative to the domain with which is used Lizmap Web Client. For example, if your main domain name is maps.example.com, then you can use a.maps.example.com, b.maps.example.com, c.maps.example.com, d.maps.example.com.

    • Ovviamente si deve configurare il server Apache «virtual host» per tener conto di questo sottodomini, per esempio con la variabile:

      ServerAlias \*.maps.example.com
      
  • Server cache storage type

    • file: Tiles cached are stored in a server directory by layer
    • sqlite: The tiles are stored in a sqlite database by layer
    • redis: the tiles are stored into a Redis database
  • Cache root directory: the folder where the cache is stored. It must be writable by the Apache server.

  • Server cache expiration time (s): the time in seconds during which each tile is retained. This is a default value for layers whose time has not been configured with the plugin.

    • Le tiles memorizzate nella cache precedenti a quella data vengono automaticamente aggiornate.
    • un valore di 0 significa che le tiles non scadono
    • Il tempo di scaddenza deve essere adattato cambiando la data.
  • Send request to QGIS Server or external service with: 2 methods php or curl. Use first if curl is not installed on the server.

  • Debug mode: saves some queries to a log file: lizmap/var/log/messages.log

  • Allow visitors to request an account: If this option is enabled, a new link “Registration” will be added in the public menu. By clicking on this link, the visitor displays a form that allows it to request an account to administrator. He must complete some fields (name, email, due to demand) then validates the form to send the request.

  • Administrator e-mail: If a valid e-mail address is given, then the Lizmap Web Client notifications will be sent. For example, each account creation request via the registration form generates an email sent to this address.

  • sender e-mail and sender name: when Lizmap sends an e-mail like notifications or for password reset, if needs the email address and the name of a sender.

proxy for External requests

Lizmap may need to access to some internet services. So, if it is installed behind a web proxy (typically in an intranet), you need to indicate what is the proxy.

You should check the checkbox «Use a proxy server» and fill these fields:

  • Host of the proxy server: the address of the proxy
  • Port of the proxy server: the tcp port of the proxy
  • Type of the proxy: the protocol used to access to the proxy: http or socks5. It is only supported when curl is used.
  • Login and password: sometimes an authentication is needed to access to the proxy
  • Domains for which the proxy will not be used: there are some requests that should not go to the proxy, typically requests to your QGIS server, or requests to a local server that serves map backgrounds etc… You have at least to set it with «localhost,127.0.0.1».

Repositori

Per ogni repository Lizmap, sono elencati:

  • The main informations: label and path
  • The list of rights with the groups concerned
  • Action buttons:
    • Visualizza: mostra una pagina che elenca le mappe presenti in questo repository
    • Modifica: mostra il modulo di modifica del repository
    • Remove: cancella il repositori dalla configurazione del Lizmap Web Client
    • Svuota cache: elimina l’intera cache di tutti i livelli dei progetti del repository

You can create a new repository using the button Create a repository located at the top and bottom of the section Repositories.

Aggiungi un repositori

Per creare un repository, devi fornire:

  • ** un id **: una parola senza spazi, accenti o caratteri speciali
  • ** un’etichetta **: il nome che verrà visualizzato per questo repository, gli accenti e gli spazi consentiti
  • a local folder path: the full path on the server to the folder that contains the QGIS projects and data
  • Allow repository themes: This option enables the possibility for the publisher to set a theme for the repository and themes for each map. See Creare temi semplici.

Definire i diritti per ogni gruppo

After creating the directory, the repository modification form is displayed automatically and defines the following rights for each group:

  • Visualizza repository :

    • all users of checked groups can access maps of this repository
    • the group anonymous is unregistered users and allows to make public maps
  • Use the Edition tool

    When this option is checked, the group users have access to the editing tool for all of Lizmap repository maps for which the edition was configured.

  • Always see complete layers data, even if filtered by login

    This option is in connection with the filtering feature data layers per group. See Filtered layers - Filtering data in function of users. Check the box for deciding which groups can see all the time all the data, even when a filter is active on some layers.
