InnoDB working, still showing “Database server does not support InnoDB storage engine message”

Question

I\'m trying to install Magento on a local server using WAMP. InnoDB is set as the default engine but it still shows me the message:

Database server does

Answer 1

I have encountered this error in default installation from downloader.

because the downloader relied on have_innodb variable, that is from mysql version 5.6.1. unavailable and official documentation (http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_have_innodb) states to use "SHOW ENGINES" instead, I have modified the downloader file accordingly:

/**
 * Check availabe InnoDB on database.
 *
 * @return Magento_Downloader_Validator
 */
protected function _checkDbInnoDb()
{
    if (!$this->_connection) {
        return $this;
    }

    $result = $this->_connection->query('SHOW ENGINES');
    while($row = $result->fetch()){
        if($row["Engine"] == "InnoDB" && $row["Support"] != "NO"){
            $this->addMessage('Database server supports InnoDB storage engine');
            return $this;
        }
    }
    $this->addError('Database server does not support InnoDB storage engine');
    return $this;
}
