# Service stats.chalec.org

Service de statistiques/métriques du candidat chaton de Libre en communs basé sur le logiciel libre StatoolInfos : https://forge.devinsy.fr/devinsy/statoolinfos.  

Responsable : Christian Momon (@cpm)  

Anciens responsables : n/a.

# Installation basique du site web

Actuellement, le site web est statique et généré par la moulinette `statoolinfos` toutes les heures.

Installer les paquets :
```
apt-get install nginx python3-certbot-nginx
```

Ouvrir les ports http (80) et https (443) :
```
ufw allow 'Nginx HTTP'
ufw allow 'Nginx HTTPS'
```

Configurer a minima le site web dans `/etc/nginx/sites-available/stats.chalec.org` :
```
server
{
    listen 80;
    listen [::]:80;

    server_name stats.chalec.org; 

    access_log /var/log/nginx/stats.chalec.org-access.log;
    error_log /var/log/nginx/stats.chalec.org-error.log;
}
```

Activer la configuration :
```
cd /etc/nginx/sites-enabled/
ln -s ../sites-available/stats.chalec.org
```

Vérifier que c'est bon et recharger :
```
nginx -t && systemctl reload nginx
```

Configurer le certificat SSl : 
```
certbot --nginx 
```

Créer un fichier générique `cat /etc/nginx/statoolinfos.conf` qui sera includé plus tard :
```
   location /.well-known/statoolinfos/ 
   {
       types 
       {
            text/plain    properties;
       }

       alias /srv/statoolinfos/well-known/statoolinfos/;
       autoindex on;
   }
```

Mettre beau le fichier `/etc/nginx/sites-enabled/stats.chalec.org` :
``` 
server
{
    listen 80;
    listen [::]:80;

    server_name stats.chalec.org;

    access_log /var/log/nginx/stats.chalec.org-access.log;
    error_log /var/log/nginx/stats.chalec.org-error.log;

    #return 302 https://$host$request_uri;
    return 302 https://stats.chalec.org$request_uri;
}

server
{
    set_real_ip_from  192.169.1.1;
    real_ip_header proxy_protocol;
    listen [::]:443 ssl ipv6only=on;
    listen 443 ssl proxy_protocol;

    server_name stats.chalec.org;

    access_log /var/log/nginx/stats.chalec.org-access.log;
    error_log /var/log/nginx/stats.chalec.org-error.log;

    ssl_certificate /etc/letsencrypt/live/stats.chalec.org/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/stats.chalec.org/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    # StatoolInfos.
    include /etc/nginx/statoolinfos.conf;

    root /var/www/stats.chalec.org;
    location = /
    {
            index index.xhtml;
    }
}
``` 

Vérifier que c'est bon et recharger :
```
nginx -t && systemctl reload nginx
```

# Déploiement du générateur de site web

## Configuration /etc/hosts

Le programme StatoolInfos va faire des requêtes web sur la vm donc il a besoin de la voir.
Pour éviter d'avoir un court-circuit proxy ipv4, modifier le fichier `/etc/hosts` pour déclarer stats.chalec.org en ipv6 locale uniquement :
```
127.0.0.1       localhost
127.0.1.1       stats

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback stats.chalec.org stats
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
```

## Configuration de Java
Java :
```
apt-get install openjdk-11-jre-headless
```

## Espace de travail
Dossiers de travail :
```
mkdir -p /srv/statoolinfos/{conf,inputs,well-known}
mkdir -p /srv/statoolinfos/well-known/statoolinfos/
ln -s /var/www/stats.chalec.org /srv/statoolinfos/www
```

Déployer les catégories : copier le dossier https://framagit.org/chatons/chatonsinfos/-/tree/master/StatoolInfos/categories dans `/srv/statoolinfos/inputs/`.

Créer un fichier de configuration pour le générateur :
```
# [Configuration]
conf.class=federation
conf.protocol=StatoolInfos-0.5

conf.crawl.input=https://stats.chalec.org/.well-known/statoolinfos/chalec.properties
conf.crawl.cache=/srv/statoolinfos/cache/

conf.htmlize.categories=/srv/statoolinfos/inputs/categories/categories.properties
conf.htmlize.input=https://stats.chalec.org/.well-known/statoolinfos/chalec.properties
conf.htmlize.directory=/srv/statoolinfos/www/
```

Créer le fichier `properties` de type `federation` nommé `/srv/statoolinfos/well-known/statoolinfos/chalec.properties` :
```

Vérifier la validé des valeurs et placer dans `/srv/statoolinfos/well-known/statoolinfos/` les images de logos nécessaires.
