This page chronicles the administrative changes to charity.progclub.org. If you make an administrative change you should document the change here. Changes are logged he in reverse chronological order with a time-stamp in the form YYYY-MM-DD hh:mm. You can use the time from whatever timezone you are in, or UTC if you're cool, but use 24 hour time. Don't worry if the changes you make have a time-stamp that is less than a time-stamp later in the page, put the latest changes at the top. Put a link to your wiki user account before the time-stamp so we know who's doing what. See the Administrative reference for other information.

Disabling IPSec

Can't get IPSec to work. Commented out /etc/network/if-up.d/ip and removed the policies from /etc/ipsec-tools.conf.

Changing jj5/admin password in Kerberos

This is so my password will be different from the Linux system password, so I can tell if the system is logging me in with my Kerberos credentials (when I configure SSH to use Kerberos, for example).

jj5@charity:~$ kadmin -p jj5/admin
Couldn't open log file /var/log/krb5.log: Permission denied
Authenticating as principal jj5/admin with password.
Password for jj5/admin@PROGCLUB.ORG:
kadmin:  cpw jj5/admin
Enter password for principal "jj5/admin@PROGCLUB.ORG":
Re-enter password for principal "jj5/admin@PROGCLUB.ORG":
Password for "jj5/admin@PROGCLUB.ORG" changed.
kadmin:  quit

Adding user jj5

jj5@charity:~$ kadmin -p jj5/admin
Couldn't open log file /var/log/krb5.log: Permission denied

root@charity:/etc/krb5kdc# krb5_newrealm
This script should be run on the master KDC/admin server to initialize
a Kerberos realm.  It will ask you to type in a master key password.
This password will be used to generate a key that is stored in
/etc/krb5kdc/stash.  You should try to remember this password, but it
is much more important that it be a strong password than that it be
remembered.  However, if you lose the password and /etc/krb5kdc/stash,
you cannot decrypt your Kerberos database.
Loading random data
Initializing database '/var/lib/krb5kdc/principal' for realm 'PROGCLUB.ORG',
master key name 'K/M@PROGCLUB.ORG'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify: 


Now that your realm is set up you may wish to create an administrative
principal using the addprinc subcommand of the kadmin.local program.
Then, this principal can be added to /etc/krb5kdc/kadm5.acl so that
you can use the kadmin program on other computers.  Kerberos admin
principals usually belong to a single user and end in /admin.  For
example, if jruser is a Kerberos administrator, then in addition to
the normal jruser principal, a jruser/admin principal should be
created.

Don't forget to set up DNS information so your clients can find your
KDC and admin servers.  Doing so is documented in the administration
guide.

Configured /wiki URLs

Decided that 'wiki' rather than 'pc' is more appropriate in the URLs for ProgClub. Updated the Apache web-site configuration files, patched LocalSettings.php in the pcwiki directory, and updated the root redirection script. The old 'pc' links will remain functional.

Reloaded a page from the web-site, and everything seems to be working well.

Copied in changes for mediawiki skin oldskool on my workstation and checked in to svn. There seems to be a new-line thing going on whereby every file got updated with different line-feed sequence (I'm guessing \r\n rather than just \n) -- it changed nearly every file, but I just checked it in anyway.

Creating a favicon.ico

MediaWiki is configured to use one, and web-browsers are requesting it, and it's 404ing, so best if I put a file there. Used iconj to generate a favicon.ico file, and used WinSCP to copy it to /var/www/www.progclub.org/favicon.ico on Charity.

Was having a problem with the favicon.ico loading in firefox, so I generated a new one with favicon.cc. I don't actually think the favicon.ico file was the problem though. But the change has been made now, and there's no point reverting it, because it's all working.

Configuring robots.txt

Having some trouble with search engine looking for URLs from the previous domain owners. Going to setup a robots.txt file to try and fix up what I can there. Found 6 methods to control what and how your content appears in search engines to help guide me.

# cd /var/www/www.progclub.org/
# vim robots.txt
User-agent: *
Disallow: /stories/
Disallow: /story/
Disallow: /members/
Disallow: /vehicles/

Will expand on this as other URLs that need addressing become apparent in the logs.

Watching the Apache web-logs

Created /home/jj5/bin/spy to setup a window to watch the web-logs.

#!/bin/bash

Setting up Etckeeper

$ sudo apt-get install etckeeper

That's really all there is to it. There's an auto commit every day, an autocommit whenever you apt-get install something and you can manually commit your changes using:

$ sudo etckeeper commit "Changed foo to achieve bar"

See the commit log for a file with:

$ sudo bzr log /etc/passwd

This means we should be able to see with reasonable accuracy what changed when, and as long as people commit their changes (and use sudo rather than abusing sudo su or the like), we'll even know who did it. Useful for quickly rolling back silly changes and catching those changes people forget to log on the wiki.

I could be accused of ignorance. When I created my key file for the CSR request I nominated a pass-phrase. This phrase is required to be entered every time you restart Apache. Gah! Until I can figure out a way to fix it I've created a script in /sbin called restart-apache which enters the key's pass-phrase automatically.

# cd /sbin
# vim restart-apache
#!/bin/bash
echo <the pass phrase> | apache2ctl graceful
# chmod u+x restart-apache
# restart-apache

Works swimmingly. Will reboot to see what happens when apache tries to load from a boot.

Apache chokes on boot. Found this article, which suggests,

# cd ~
# cp progclub.key progclub.key.pass-phrase
# openssl rsa -in progclub.key.pass-phrase -out progclub.key
# chmod 400 progclub.*
# reboot

Hopefully Apache comes back up this time... yep!

Will keep the restart-apache script in sbin, but will remove the part that specified the key pass-phrase.

Getting an HTTPS certificate

Searched for certificate sni cheap, found Go Daddy SSL Certificate. Decided on the Multiple Domains UCC - A$82.93/yr setup, which looks like it will suit us. Picked up to 5 domains for 3 years. It offered me free .mobi registration, so I added progclub.mobi. I then also added progclub.biz and progclub.co, I'm a sucker. Registration information recorded in Blackbrick Account Manager. Setup the nameservers for the new domains to point to ns*.slicehost.net via My Account.

Had to generate a Certificate Signing Request (CSR) per these instructions (for Apache 2.x).

# cd ~
# openssl genrsa -des3 -out progclub.key 2048
# openssl req -new -key progclub.key -out progclub.csr

See Blackbrick Account Manager for full details.

Certificate Type

  • Hosting: Third Party Hosting
  • Domain Name: www.progclub.org
  • Certificate Issuing Organization: Go Daddy
  • Subject Alt Names: www.progclub.net www.progclub.mobi www.progclub.info www.progclub.co
You're through!
Your certificate will be issued shortly.
You can monitor the progress of your certificate application by going to the
Pending Requests folder and clicking your Common Name. When we are through
verifying your application, you will receive an email with further instructions.

Didn't find a LocalSettings.php, which is what I was expecting, so reading INSTALL.

# less INSTALL

It told me to navigate to the setup page. The setup page complained about a missing LocalSettings.php, so they haven't changed that after all. Clicked on setup the wiki.

Specified,

* Your language: en - English
* Wiki language: en - English

Clicked continue, and amoung it's checks was a complaint:

Could not find a suitable database driver! You need to install a database driver for PHP. The following
database types are supported: MySQL, PostgreSQL, Oracle, SQLite.
If you are on shared hosting, ask your hosting provider to install a suitable database driver. If you compiled
PHP yourself, reconfigure it with a database client enabled, for example using ./configure --with-mysql. 
If you installed PHP from a Debian or Ubuntu package, then you also need install the php5-mysql module.

So,

# apt-get install php5-mysql
# apache2ctl graceful

Then reloaded the config page,

The environment has been checked. You can install MediaWiki.

Clicked continue, and got the Connect to database page. Looks like I'm going to need a database user for the wiki, so

# mysql -h localhost -u root --password=<password>

mysql> create user 'pcwiki'@'localhost' identified by '<password>';
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye

Back on the config page:

* Database type: MySQL
* Database host: localhost
* Database name: pcwiki
* Database table prefix: pcwiki__
* Database username: pcwiki
* Database password: <password>

Clicked continue, and got the Database settings page. Specified,

* Database account for web access: Use the same account as for installation
* Storage engine: InnoDB (the default, other choice was MyISAM)
* Database character set: UTF-8 (not the default, the default choice was Binary)

Clicked continue, and got the Name page. Specified,

* Name of wiki: ProgClub
* Project namespace: Same as the wiki name: ProgClub

Configuration for the Administrator account,

* Your name: John
* Password: <password>
* Password again: <password>
* E-mail address: jj5@jj5.net
You are almost done! You can now skip the remaining configuration and install the wiki right now.

Chose Ask me more questions, and got the Options page. Specified,

* User rights profile: Traditional wiki
* Copyright and license: No license footer
* Enable outbound e-mail: true
* Return e-mail address: wiki@progclub.org
* Enable user-to-user e-mail: true
* Enable user talk page notification: true

* Directory for deleted files: /var/www/www.progclub.org/mediawiki-1.17.0/images/deleted
* Logo URL: /res/img/logo.png
* Settings for object caching: No caching

Clicked Continue, and got the confirmation page. Clicked Continue again. Got an error because the database user couldn't create the database. Created the database manually,

# mysql -h localhost -u root --password=<password>
Welcome to the MySQL monitor.  Commands end with ; or \g.

Query OK, 1 row affected (0.00 sec)
mysql> exit

Decided it would be easier to let MediaWiki create the database, so went back and specified the database config details to use the root user. I will change this to be the pcwiki user manually after the database has been created.

Congratulations! You have successfully installed MediaWiki.
The installer has generated a LocalSettings.php file. It contains all your configuration.
You will need to download it and put it in the base of your wiki installation (the same
directory as index.php). The download should have started automatically.
If the download was not offered, or if you cancelled it, you can restart the download by
clicking the link below: Download LocalSettings.php
Note: If you do not do this now, this generated configuration file will not be available
to you later if you exit the installation without downloading it.
When that has been done, you can enter your wiki.

Downloaded the LocalSettings.php file and copied it to /var/www/www.progclub.org/mediawiki.1.17.0

Edited LocalSettings.php and changed the database user:

$wgDBuser           = "pcwiki";
$wgDBpassword       = "<password>";

Also added an article path:

$wgArticlePath      = "/pc/$1";

Also need to grant access for pcwiki user:

# mysql -h localhost -u root --password=<password>
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 54
Server version: 5.1.41-3ubuntu12.10 (Ubuntu)
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> grant all privileges on pcwiki.* to pcwiki@localhost;
Query OK, 0 rows affected (0.11 sec)
mysql> exit
Bye

Then need to edit apache conf file to include the pc alias:

# cd /etc/apache2/sites-enabled/
# vim 000-default

added,

Alias /pc /var/www/www.progclub.org/mediawiki-1.17.0/index.php

then,

# apache2ctl graceful

Also,

# cd /var/www/www.progclub.org/
# mkdir res
# mkdir res/img

Then uploaded a logo.png to there with WinSCP. The logo settings hadn't been properly specified in the generated LocalSettings.php file, so,

# cd /var/www/www.progclub.org/mediawiki-1.17.0/
# vim LocalSettings.php

and changed the logo setting,

$wgLogo             = "/res/img/logo.png";

Checked the wiki, and it's all working nicely.

Preparing WWW hosting

# cd /var/www
# mkdir www.progclub.org
# mv index.html test.php www.progclub.org/
# ls
# cd www.progclub.org/
# ls
index.html  test.php

Everything is in order.

# cd /etc/apache2/sites-enabled/
# ls
000-default
# vim 000-default

Specified ServerAdmin,

ServerAdmin jj5@progclub.org

Changed document root,

DocumentRoot /var/www/www.progclub.org/

Changed the <Directory /var/www/> section to,

<Directory /var/www/www.progclub.org/>

Saved changes and quit vim. Restarted apache,

# apache2ctl graceful

Apache complained,

apache2: Could not reliably determine the server's fully qualified domain name, using charity.progclub.org for ServerName

Searched for "apache2: Could not reliably determine the server's fully qualified domain name, using " and found an answer.

Ran,

# hostname charity.progclub.org

which I guess is a better way to set the hostname than editing /etc/hostname like I did. :P

Ran,

# apache2ctl graceful

again, and got the same error,

apache2: Could not reliably determine the server's fully qualified domain name, using charity.progclub.org for ServerName

Tried a reboot to see if the hostname is updated after that,

# reboot

Still having problems with,

# apache2ctl graceful

So read more of the answer, and then,

# hostname charity
# vim /etc/hosts

Specified the file contents as

127.0.0.1          localhost localhost.localdomain
67.207.128.184     charity charity.progclub.org

Then rebooted,

# reboot

Ran hostname and got,

# hostname
charity.progclub.org

So edited /etc/hostname and specified

charity

Rebooted,

# reboot

Searched for "/etc/hostname", and found an answer. Short name goes in /etc/hostname, so we should be configured correctly now. Apache is still complaining though,

# apache2ctl graceful
apache2: Could not reliably determine the server's fully qualified domain name, using 67.207.128.184 for ServerName

and it's using the IP address rather than charity.progclub.org now. Will manually specify ServerName in /etc/apache2/sites-enabled/000-default

# cd /etc/apache2/sites-enabled/
# vim 000-default

Added,

ServerName  charity.progclub.org

Ran,

# apache2ctl graceful

again, and got the same friggin' error! More web-searching... found a different answer, tried editing /etc/hosts to put the names the other way around,

# vim /etc/hosts
127.0.0.1          localhost.localdomain localhost
67.207.128.184     charity.progclub.org charity

Rebooted,

# reboot

Tried apache2ctl again,

# apache2ctl graceful

And got no error! Yay!

Checked

* www.progclub.org

and found everything to be working. Web hosting is now configured.

PHP software installation

I created a test.php file at /var/www/test.php to see if PHP was working out-of-the-box. I navigated to test.php to check, and it tried to download the PHP file, so I guess PHP isn't installed.

The test.php file I used was,

<? phpinfo(); ?>

Searched for PHP installation candidate,

# apt-cache search php5 | less

Found php5, which looks promising.

# apt-get install php5

Noticed the complaining about the server's fully qualified domain name, so

# vim /etc/hostname

and changed from

charity

to

charity.progclub.org

Then I rebooted,

# reboot

Logged in again and checked the hostname,

# hostname

which was correctly reported as,

charity.progclub.org

Then I navigated to the test.php page, and got back the phpinfo().

Apache and MySQL software installation

Searched for MySQL software,

# apt-cache search mysql | less

Found mysql-server, which looks like a good candidate.

Searched for Apache software,

Configuring mysql-server-5.1

Dpkg showed a configuration screen for configuring the root password. I set one.

Apache and MySQL software installation, continued

I rebooted after installing the above software,

# reboot

I checked the Apache installation by navigating to www.progclub.org and It Works!

John 2011-07-25 16:34

SSH'ed in as root and ran:

# apt-get update
# apt-get dist-upgrade
# reboot

John 2011-07-25 16:00

Had to stuff around with resetting the root password on charity, but remote logins via SSH are working now for root.

John 2011-07-25 15:52

Configured the name server with progclub.org, progclub.net and progclub.info DNS zones on slicehost. The SliceManager should be used to maintain the DNS records for progclub.
