VPS Configuration (OVH)

This is done via OVH Manager (https://www.ovh.com/manager/).

Service name prime.immie.org

Original name was vps282013.ovh.net.

Reverse DNS

In Advanced mode, click Modify the Reverse DNS.

IP 91.134.134.85
Name prime.immie.org

Original name was 85.ip-91-134-134.eu

Server Configuration

Guides

Guides I followed to install the server:

I added testing and unstable repositories.

/etc/apt/sources.list: 

# Stable
deb http://ftp.debian.org/debian/ jessie main
deb http://security.debian.org/ jessie/updates main

# Testing
deb http://ftp.debian.org/debian/ testing main
deb http://security.debian.org/ testing/updates main

# Unstable / Sid
deb http://ftp.debian.org/debian/ sid main

# Backport
deb http://ftp.debian.org/debian jessie-backports main

/etc/apt/preferences: 

# cat /etc/apt/preferences 
Package: *
Pin: release a=stable
Pin-Priority: 500

Package: *
Pin: release a=jessie-backports
Pin-Priority: 475

Package: *
Pin: release a=testing
Pin-Priority: 450

Package: *
Pin: release a=unstable
Pin-Priority: 400

Upgraded some packages from testing/unstable: [1]

  • Follow certbot guide.
  • TODO — See IMPORTANT NOTES below:
IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/www.immie.org/fullchain.pem. Your cert will
   expire on 2016-10-02. To obtain a new or tweaked version of this
   certificate in the future, simply run certbot again with the
   "certonly" option. To non-interactively renew *all* of your
   certificates, run "certbot renew"
 - If you lose your account credentials, you can recover through
   e-mails sent to m-certbot@immie.org.
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le
  • Now all certificates are stored in a single file. Same for the key:
SSLCertificateFile      /etc/letsencrypt/live/www.immie.org/fullchain.pem

MediaWiki Tuning

Following MediaWiki guide and Aaron's guide:

  • Install php-mbstring
apt install php-mbstring
  • Enable $wgCacheDirectory. In LocalSettings.php:
$wgCacheDirectory = "$IP/cache";

Create the directory: 

cd /var/www/miki.immie.org/mediawiki
sudo -u www-data mkdir cache
chmod 700 cache

Install memcached: 

apt-get install memcached php5-memcached
systemctl restart apache2.service

Add to LocalSettings.php 

$wgMainCacheType = CACHE_MEMCACHED;
$wgParserCacheType = CACHE_MEMCACHED; # optional
$wgMessageCacheType = CACHE_MEMCACHED; # optional
$wgMemCachedServers = array( "127.0.0.1:11211" );

$wgSessionsInObjectCache = true; # optional
$wgSessionCacheType = CACHE_MEMCACHED; # optional

To Do

  • Return error 403 - Forbidden when visiting https://miki.immie.org (server root).
  • Change immie password because we can brute-force it via webmin interface, or forbid immie.
