mysql> use typo3;
mysql> update be_users set password='bacb98acf97e0b6112b1d1b650b84971' where username = 'admin';


This resets the admin user password to “joh316″.

(2009-12-04 Update: This does not work with RHEL 5.4. The mysql ruby gem requires ruby 1.8.6 and RHEL 5.4 only ships with ruby 1.8.5)

Using yum install ruby and mysql. The command below does not list all the required packages, but due to dependencies, the additional packages will be installed (or should be – this is all from memory).

[bm@app3 ~]$ sudo su -
[root@app3 ~]# yum install ruby ruby-devel ruby-libs ruby-irb \
> ruby-rdoc subversion-ruby mysql-server mysql-devel
[....]

Complete the basic configuration of MySQL.
[root@app3 ~]# /sbin/chkconfig mysqld on
[root@app3 ~]# service mysqld start
[root@app3 ~]# mysql_secure_installation


Download and install RubyGems. As of the date this post was written, the latest version is 1.1.1.
[root@app3 ~]# wget http://rubyforge.org/frs/download.php/35284/rubygems-1.1.1.zip
[root@app3 ~]# unzip rubygems-1.1.1.zip
[root@app3 ~]# cd rubygems-1.1.1
[root@app3 rubygems-1.1.1]# ruby setup.rb
[root@app3 ~]# cd ..
[root@app3 ~]# rm -rf rubygems-1.1.1


Now install Rails, Mongrel, the Ruby MySQL interface, Capistrano
[root@app3 ~]# gem install rails --include-dependencies --no-rdoc --no-ri
[root@app3 ~]# gem install mongrel --include-dependencies --no-rdoc --no-ri
[root@app3 ~]# gem install mysql -- --with-mysql-config=/usr/bin/mysql_config
[root@app3 ~]# gem install capistrano --include-dependencies --no-rdoc --no-ri


Phusion’s passenger gem provides a “mod_rails” module for Apache. The installation is very straight forward.
[root@app3 ~]# gem install passenger
[root@app3 ~]# passenger-install-apache2-module


Just follow the on-screen instructions to finish the installation.

Download the latest stable version from the phpMyAdmin web site, and extract it to a location of your choice. I prefer to keep the installation outside of the web root and use an apache alias to reference it.

[root@app3 ~]# cd /var/www
[root@app3 ~]# wget http://superb-west.dl.sourceforge.net/sourceforge/phpmyadmin/phpMyAdmin-2.11.5.2-all-languages-utf-8-only.tar.gz
[root@app3 ~]# tar xzf phpMyAdmin-2.11.5.2-all-languages-utf-8-only.tar.gz

Now that’s a lengthy directory name! Let’s create a link to that directory with a more friendly name.

[root@app3 ~]# ln -s phpMyAdmin-2.11.5.2-all-languages-utf-8-only phpMyAdmin


SELinux may generate a number of errors regarding this new directory that will be referenced by the apache web server. Let’s correct the security context of the entire phpMyAdmin directory structure.

[root@app3 ~]# chcon -R -h -t httpd_sys_content_t \
> phpMyAdmin-2.11.5.2-all-languages-utf-8-only


Configure the phpMyAdmin installation to use http authentication. We’ll make sure it is secure by forcing SSL encryption using apache directives in a later step.

[root@app3 ~]# cd phpMyAdmin
[root@app3 ~]# cp config.sample.inc.php config.inc.php
[root@app3 ~]# vi config.inc.php


Change the line:
$cfg['Servers'][$i]['auth_type'] = 'cookie';
to:
$cfg['Servers'][$i]['auth_type'] = 'http';

Now we need to configure the apache web server. To keep things modular, create a file phpmyadmin.conf in /etc/httpd/conf.d. Any configuration directives in this file will automatically be loaded into the main apache configuration when the daemon is restarted.

[root@app3 ~]# vi /etc/httpd/conf.d/phpmyadmin.conf


The phpmyadmin.conf file should contain the following directives. Just modify the paths to suit your installation.

Alias /phpmyadmin /var/www/phpMyAdmin
<Directory "/var/www/phpMyAdmin">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
    SSLRequireSSL
</Directory>

Restart apache and see if your installation works.

[root@app3 ~]# service httpd restart


If there are problems, check your logs. It is possible that SELinux may be complaining about something.
