History

From 2012 to 2016, OFF and OBF have been running on part of an OVH server (also used for other purposes):

  • cat /etc/debian_version -> 6.0.10 (squeeze)
  • 1 apache 2.4 setup as reverse proxy to serve static files (manually built)
  • 1 apache 1.3 + mod_perl for OFF (manually built)
  • 1 apache 1.3 + mod_perl for OBF (manually built)
  • MongoDB 2.4.12 (installed from mongodb provided packages)

From 2016 to 2018, 1 dedicated OVH server running:

  • 1 nginx reverse proxy to serve static files (installed with apt-get)
  • 1 apache 2.4 + mod_perl (installed with apt-get)
    • running two separate instances on different ports, 1 for OFF and 1 for OBF
  • 1 MongoDB

2012-2016 server install log

OFF and OBF have been hosted from 2012 to 2016 on a (now very old) OVH dedicated server that is also hosting other projects. On June 13th 2016, a new dedicated server has been ordered specifically for OFF and OBF.

Hardware

Server setup

Server configuration

  • uname -a
    • Linux ns3362784.ip-37-187-74.eu 3.14.32-xxxx-grs-ipv6-64 #7 SMP Wed Jan 27 18:05:09 CET 2016 x86_64 GNU/Linux
  • perl -v
    • This is perl 5, version 20, subversion 2 (v5.20.2) built for x86_64-linux-gnu-thread-multi

Basic configuration

  • apt-get update
  • apt-get upgrade
  • apt-get install fail2ban
  • apt-get install sudo
  • apt-get install build-essential
  • apt-get install git


Users

  • admin users with sudo access
  • off user

IP failover

1 ip failover for each service so that we can easily switch servers

  • OFF: 178.33.252.125
  • OBF: 178.33.104.169

Add to /etc/network/interfaces : 


post-up /sbin/ifconfig eth0:0 178.33.104.169 netmask 255.255.255.255 broadcast 178.33.104.169
post-down /sbin/ifconfig eth0:0 down

post-up /sbin/ifconfig eth0:1 178.33.252.125 netmask 255.255.255.255 broadcast 178.33.252.125
post-down /sbin/ifconfig eth0:1 down

/etc/init.d/networking restart

  • [ ok ] Restarting networking (via systemctl): networking.service.

DNS

Product Opener needs a domain, with a A record for the domain itself and another wildcard A record for all subdomains.

  • openbeautyfacts.org. 0 A 178.33.104.169
  • *.openbeautyfacts.org. 0 A 178.33.104.169

For testing the new server, we will be using openfoodfacts.eu

Product Opener dependencies

exim
  • apt-get install exim4
  • dpkg-reconfigure exim4-config
    • Internet Site mail is sent by smtp
    • 127.0.0.1
MongoDB

See https://docs.mongodb.com/manual/tutorial/install-mongodb-on-debian/

apt-get install mongodb

MongoDB shell version: 2.4.10

service mongod stop mv /var/lib/mongodb /home/mongodb

vi /etc/mongod.conf

Apache / mod_perl and nginx

Apache 2 + mod_perl serve the dynamically generated HTML pages from Product Opener.

nginx is installed on port 80 as a reverse proxy. It serves the static files (images, JS, CSS etc.) and proxies the dynamic requests to the Apache server on another port.

apt-get install apache2

  1. stop apache in order to be able to install nginx (default port 80)

service stop apache2

apt-get install nginx

Apache configuration

Note: imagemagick + mod_perl seems to crash Apache in the worker / event MPM, use prefork.

remove event and then:

/etc/apache2-off/mods-enabled# ln -s ../mods-available/mpm_prefork.conf mpm_prefork.conf /etc/apache2-off/mods-enabled# ln -s ../mods-available/mpm_prefork.load mpm_prefork.load

Set the user to off

vi /etc/apache2/envvars 

#export APACHE_RUN_USER=www-data
export APACHE_RUN_USER=off
#export APACHE_RUN_GROUP=www-data
export APACHE_RUN_GROUP=off

Debugging:

If Apache does not start, check the apache2 logs (e.g. for apache2-obf) : 

/var/log/apache2-obf# tail -f error.log

-> forgot to create startup_apache2.pl, going to copy the one from off and change the path in it.

More debugging:

If mod_perl starts, it loads some modules from cgi/startup_apache2.pl, and may fail if some modules are missing. Check /home/obf/logs/error_log: 

[Mon Jul 04 18:31:11.501044 2016] [perl:error] [pid 23498:tid 116442525869952] Can't locate Math/Random/Secure.pm in @INC (you may need to install the Math::Random::Secure module)
Running a 2nd Apache instance for OBF

OFF and OBF share the same code (except some configuration in the Config.pm and SiteLang.pm modules), but the code is not made to run two separate servers. So we need two run two separate instances of Apache, one for OFF and one for OBF. This also allows to restart one but not the other, to run different versions of the code etc.

Note: we use the off user for both OFF and OBF so that OBF can read and write in /home/off/users

There is some support to run multiple Apache instances. Documentation is in /usr/share/doc/apache2/README.multiple-instances
