| Installation instructions for Product Opener (see [[Project:Product Opener]]). | | Installation instructions for Product Opener (see [[Product Opener]]). |
|
| |
|
| == Before you start ==
| | The newest installation instructions are on https://en.wiki.openfoodfacts.org/Infrastructure#Server_configuration |
| | |
| Product Opener is not yet released as open source. The instructions below are for reference and for early testers of Product Opener. They are very likely to change as the code will be restructured, made more independent of proprietary code and specific Open Food Facts uses etc.
| |
| | |
| When it is released, Product Opener will have much easier to use install scripts and instructions.
| |
| | |
| == Install directory ==
| |
| | |
| Instructions below use /home/obf for the install directory, replace with your install dir.
| |
| | |
| == Product Opener code ==
| |
| | |
| === Configuration ===
| |
| | |
| ==== startup.pl ====
| |
| | |
| This file is used to preload Perl module in Apache.
| |
| It contains a path that needs to be updated:
| |
| | |
| <pre>
| |
| # Needs to be configured
| |
| use lib "/home/obf/cgi/";
| |
| </pre>
| |
| | |
| ==== Config.pm ====
| |
| | |
| ==== Config2.pm ====
| |
| | |
| Contains info about the domain, database and path. This is separated from Config.pm so that it is easy to create test instance that share the same configuration in Config.pm but are on other domains.
| |
| | |
| <pre>
| |
| # server constants
| |
| $domain = "openbeautyfacts.org";
| |
| | |
| # server paths
| |
| $www_root = "/home/obf/html";
| |
| $data_root = "/home/obf";
| |
| | |
| $mongodb = "obf";
| |
| </pre>
| |
| | |
| === Required Perl modules ===
| |
| | |
| The following Perl modules need to be installed (some of them might be included with Perl).
| |
| | |
| To install a module, you can sometimes use packages.
| |
| | |
| e.g. on Debian / Ubuntu : apt-get install libdatetime-perl
| |
| | |
| Or you can use cpan: <code>cpan install DateTime</code>
| |
| | |
| Or cpanm: <code>perl cpanm --installdeps .</code>
| |
| | |
| <pre>
| |
| Cache::Memcached::Fast
| |
| Crypt::PasswdMD5
| |
| DateTime
| |
| DateTime::Format::Mail
| |
| Digest::MD5
| |
| Digest::SHA1
| |
| Encode::Punycode
| |
| File::Copy
| |
| File::Path
| |
| Geo::IP
| |
| Getopt::Long
| |
| GraphViz2
| |
| Hash::Util
| |
| HTML::Defang
| |
| HTML::Entities
| |
| Image::Magick
| |
| Image::OCR::Tesseract
| |
| IPC::Open3
| |
| JSON
| |
| LWP::Authen::Digest
| |
| </pre>
| |
| | |
| == MongoDB database ==
| |
| | |
| Install Mongodb.
| |
| | |
| The mongodb database name is configured in cgi/Config.pm
| |
| | |
| The mongodb database is created when the first product is added.
| |
| | |
| === MongoDB indexes ===
| |
| | |
| See [[Product Opener mongodb indexes]]
| |
| | |
| == Apache servers ==
| |
| | |
| In production we use a light weight Apache web server for static files (e.g. images) that does reverse proxying to a modperl Apache server that dynamically generates the HTML pages.
| |
| | |
| If the trafic is low or moderate, you can use only one Apache mod_perl server that also serves images etc.
| |
| | |
| In the example below, the Apache mod_perl server listens on port 19000.
| |
| | |
| === Light-weight reverse proxy for static files ===
| |
| | |
| Compile:
| |
| | |
| ./configure --prefix=/home/xyz/proxy --enable-rewrite --enable-proxy --enable-proxy_http --disable-userdir --enable-headers --enable-expires --enable-mime --enable-so --with-included-apr | |

| === modperl Apache server for dynamic pages ===
| |
| | |
| * download the latest version of the source of the Apache httpd server from the 2.2 branch (2.2.29 when writing this)
| |
| ** do not use the 2.4 branch as mod_perl is not yet compatible with it
| |
| * extract the source
| |
| * ./configure --with-mpm=prefork --prefix=/home/obf/apache --enable-rewrite --enable-proxy --enable-proxy_http --enable-deflate --disable-userdir --enable-headers
