Install mysql Workbench


MySQL Workbench is a unified visual tool for database architects, developers, and DBAs. MySQL Workbench provides data modeling, SQL development, and comprehensive administration tools for server configuration, user administration, backup, and much more. MySQL Workbench is available on Windows, Linux and Mac OS X.

The simplest way to install it in Ubuntu or Linux Mint is via Olivier Berten’s Miscellaneous PPA:

sudo add-apt-repository ppa:olivier-berten/misc
sudo apt-get update
sudo apt-get install mysql-workbench


Depending on the Ubuntu version you are installing on, MySQL Workbench version will be between 5.2 and 6.0. For example, using this PPA I installed MySQL 5.2 on Ubuntu 12.04 and 6.0 on Ubuntu 13.10.



Redirect requests using .htaccess and mod_rewrite

  1. Make sure Apache .htaccess is enabled (by default it is enabled in Ubuntu)
  2. Make sure the Apache module mod_rewrite is enabled. Execute:

sudo a2enmod rewrite

..and see if rewrite is listed here:

sudo apache2ctl -M

and then you can redirect requests using RewriteRules. Example:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?_REQUEST=$1 [L]

Check your apache.conf

<Directory /var/www/html/>
 Options Indexes FollowSymLinks 
 AllowOverride All
 Require all granted
