Typo3 installation on OVH mutualised server

Get Typo3

Download dummy-3.5.0.zip from typo3.org. (Any other package should work), and unzip it locally.

Modify a few files

in /typo3/init.php

define('PATH_thisScript',str_replace('//','/', str_replace('\\','/', php_sapi_name()=='cgi'||php_sapi_name()=='isapi' ? $HTTP_SERVER_VARS['PATH_TRANSLATED']: $HTTP_SERVER_VARS['SCRIPT_FILENAME'])));  

becomes

define('PATH_thisScript',str_replace('//','/', str_replace('\\','/', $HTTP_SERVER_VARS['SCRIPT_FILENAME'])));        


in /index.php

define('PATH_thisScript',str_replace('//','/', str_replace('\\','/', php_sapi_name()=='cgi'||php_sapi_name()=='isapi'  ? $HTTP_SERVER_VARS['PATH_TRANSLATED']: $HTTP_SERVER_VARS['SCRIPT_FILENAME'])));  

becomes

define('PATH_thisScript',str_replace('//','/', str_replace('\\','/', $HTTP_SERVER_VARS['SCRIPT_FILENAME'])));        


in /typo3/t3lib/class.t3lib_install.php

function getDatabaseList() {
    $dbArr=array();
    if ($result = @mysql_pconnect(TYPO3_db_host, TYPO3_db_username, TYPO3_db_password)) {
      $db_list = mysql_list_dbs();
      while ($row = mysql_fetch_object($db_list)) {
        if (mysql_select_db($row->Database)) {
          $dbArr[]=$row->Database;
        }
      }
    }
    return $dbArr;
  }  

becomes

function getDatabaseList() {
    $dbArr=array();
    $dbArr[]='your_table';
    return $dbArr;
  }       

in /typo3/t3lib/class.t3lib_div.php

switch((string)$getEnvName) {
    case 'SCRIPT_NAME':
      return php_sapi_name()=='cgi' ? $HTTP_SERVER_VARS['PATH_INFO'] : $HTTP_SERVER_VARS['SCRIPT_NAME'];       

becomes

switch((string)$getEnvName) {
    case 'SCRIPT_NAME':
      return $HTTP_SERVER_VARS['SCRIPT_NAME'];  

Test it

Go to http://www.mydomain.com/. If it doesn't get to the install process, go there manually typing : http://www.mydomain.com/typo3/install/. Most of the configuration will be done automatically.

Set up the database, using your parameters. You should be able to see one table in the list, the one you hard-coded in class.t3lib_install.php. You can then import typo3conf/database.sql (all tables), which you can do from the install script.
