Install

Add Repository

Piwik is not present in Debian repositories. However they provide their own repository. You can add it using

$ wget https://debian.piwik.org/repository.gpg -qO piwik-repository.gpg
$ sha256sum --binary piwik-repository.gpg
0d7c880f6c838bba2d02817dcacfc97fc538b1ebcdb41c3106595265c0d371d4 *piwik-repository.gpg
$ cat piwik-repository.gpg | sudo apt-key add -
OK
$ echo "deb https://debian.piwik.org/ piwik main" | sudo tee /etc/apt/sources.list.d/piwik.list > /dev/null
$ sudo apt update

Configure PHP

Edit file /etc/php5/mods-available/local-common.ini and add /usr/share/piwik/:/etc/piwik/:/var/lib/piwik/ to the open_basedir setting.

Reload PHP:

$ sudo service php5-fpm reload

Install Package

$ sudo apt install piwik geoip-database/jessie-backports geoip-database-extra/jessie-backports

DNS

Create a DNS entry for piwik. For this guide, we will use piwik.example.org.

Webserver

1. Create the config file /etc/nginx/sites-available/piwik.example.org

   server {
       include snippets/listen-http.conf;
       server_name piwik.example.org;
   
       access_log /var/log/nginx/piwik.example.org.access.log;
       error_log /var/log/nginx/piwik.example.org.error.log info;
   
       include snippets/acme-challenge.conf;
       include snippets/https-permanent-redirect.conf;
   }
   
   server {
       include snippets/listen-https.conf;
       server_name piwik.example.org;
   
       access_log /var/log/nginx/piwik.example.org.access.log;
       error_log /var/log/nginx/piwik.example.org.error.log info;
   
       include snippets/acme-challenge.conf;
   
       #include snippets/ssl.conf;
       #ssl_certificate      /etc/letsencrypt/live/piwik.example.org/fullchain.pem;
       #ssl_certificate_key  /etc/letsencrypt/live/piwik.example.org/privkey.pem;
       #include snippets/hsts.conf;
   
       # Protect interface during initial setup
       # To be removed once admin password is set
       auth_basic            "You shall not pass!";
       auth_basic_user_file  /etc/nginx/generic.htpasswd;
       
       include snippets/security-headers.conf;
       include snippets/x-frame-options-deny.conf;
   
       root /usr/share/piwik;
       index index.php;
   
       location / {
           location ~* ^.+\.(?:css|gif|html?|jpe?g|js|png|swf)$ {
               expires max;
           }
   
           ## Do not serve HTML files from the /tmp folder.
           location ~* ^/tmp/.*\.html?$ {
               return 404;
           }
   
           location ~* (?:DESIGN|(?:gpl|README|LICENSE)[^.]*|LEGALNOTICE)(?:\.txt)*$ {
               return 404;
           }   
           location ~* \.(?:bat|git|ini|sh|svn[^.]*|txt|tpl|xml|py)$ {
               return 404;
           }   
   
           try_files $uri /index.php?$query_string;
       }   
   
       location = /index.php {
           include fastcgi.conf;
           fastcgi_pass php5;
       }   
   
       location = /piwik.php {
           include fastcgi.conf;
           fastcgi_pass php5;
       }   
   
       location ~* ^.+\.php$ {
           return 404;
       }   
   
       location = /robots.txt {
           return 200 "User-agent: *\nAllow: /piwik.js\nAllow: /piwik.php\nDisallow: /\n";
       }   
   }
   

2. Activate the configuration with

   $ sudo nginx_modsite -e piwik.example.org
   Would you like to reload the Nginx configuration now? (Y/n) Y
   

3. Edit file /usr/local/etc/certmanage/main.json and add the following to the list

   {
       "domains": ["piwik.example.org"],
       "reload": [["/bin/systemctl", "reload", "nginx.service"]]
   }
   

4. Get your certificate

   $ sudo /usr/local/sbin/certmanage
   Renewing certificate for piwik.example.org that will expire on 0001-01-01
   
   Saving debug log to /var/log/letsencrypt/letsencrypt.log
   Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org
   Obtaining a new certificate
   Performing the following challenges:
   http-01 challenge for piwik.example.org
   Using the webroot path /var/www/acme-challenge for all unmatched domains.
   Waiting for verification...
   Cleaning up challenges
   Generating key (2048 bits): /etc/letsencrypt/keys/1764_key-certbot.pem
   Creating CSR: /etc/letsencrypt/csr/1764_csr-certbot.pem
   
   IMPORTANT NOTES:
    - Congratulations! Your certificate and chain have been saved at
      /etc/letsencrypt/live/piwik.example.org/fullchain.pem. Your cert
      will expire on 2025-02-19. To obtain a new or tweaked version of
      this certificate in the future, simply run certbot again. To
      non-interactively renew *all* of your certificates, run "certbot
      renew"
    - If you like Certbot, please consider supporting our work by:

   Restarting services:
   systemctl reload nginx.service
   

5. Uncomment the ssl related lines in /etc/nginx/sites-available/piwik.example.org and run

   $ sudo systemctl reload nginx.service
   

Create Database

For the rest of the guide, we will use a dedicated database and user named piwik.

You can create them using PhpMyAdmin or any other method.

Transfer Existing Installation

Copy Database

On the old server, backup you database using

$ mysqldump -u root -aqp piwik | gzip > piwik.sql.gz

And restore it on the new server using

$ zcat piwik.sql.gz | mysql -u root -p piwik
