Step by Step solution: 1. Go to /etc/rc.d/init.d/mysqld 2. Locate line: /usr/bin/mysqld_safe --defaults-file=/etc/my.cnf 3. Add option: --log-slow-queries="/var/log/slow-queries.log" to this line. Now the line becomes: /usr/bin/mysqld_safe --defaults-file=/etc/my.cnf --log-slow-queries="/var/log/slow-queries.log" 4. Create an empty file: touch /var/log/slow-queries.log 5. Give permission: chmod 644 /var/log/slow-queries.log 6. Restart mysql mysqld will log all slow queries to this file.

Often with your impressive Drupal installation, you would wish to run multiple sites on a single code base, each independent enough to look like an indepedent site and an independent domain name. As an example, look at the sites www.mplstutorial.com and www.programmingbulls.com installed on the same code base and single drupal installation. Therefore, www.site1.com would become one site and www.site2.com would become another on a single Drupal installation.

I came across this problem while reading the architecture of TIVOLI Access Management.Well, after discussing a while with people i found the correct difference between Forward Proxy and Reverse Proxy and the advantage of using them.

Elgg provides out of the box functionality for a social networking site like Orkut, Hi5, Myspace, but Drupal is far more flexible. It seems Elgg is not tested and used as much as Drupal. I have been working on Drupal for a long time now and my faith on it has only increased, though, I had to make changes to the code and modules at times.

I have been coding in PHP and MYSQL using my favourite LAMPP for a long time now using VIM. And with the growing complexity of sysytems, it was becoming increasing difficult to keep up with VIM. I was working on Drupal and was writing, debugging few modules. I needed a debugger badly and then I stumbled upon Ecipse PDT. It took a while to set up, but once it was up, it was a power tool that I probably should have gotten earlier. Eclipse Perl plugin too is cool and use it often to debug perl applications. Eclipse PHP plugin is known as PHP Development Tool (PDT).

If you want your lampp server to start automatically when the linux boots by accident or knowingly, create a following linux script and call it start_lampp.sh #!/bin/bashservice httpd stop/opt/lampp/lampp restart Copy start_lampp.sh to /etc/init.d/: shell> cp start_lampp.sh /etc/init.d/ Give executable permissions: shell> chmod +x /etc/init.d/start_lampp.sh Create a symbolic link:
