title: MySQL does not display during setup of Zabbix
body: <p>I have issue during Zabbix 2.4-1 installation on ubuntu 14.04.
  I used manual from <a href="https://www.zabbix.com/documentation/2.4/manual/installation/install_from_packages?s[]=ubuntu" rel="nofollow noreferrer">official site</a>, installation was successful, no errors.
  Next I created user 'zabbix' with all privileges and database 'zabbix' and imported schema.sql, images.sql and data.sql from Zabbix archive. Then I changed configuration files in /etc/zabbix dir:</p>
  
  <h2>zabbix.conf.php</h2>
  
  <pre><code>// Zabbix GUI configuration file
  global $DB;
  
  // Valid types are MYSQL, SQLITE3 or POSTGRESQL
  $DB["TYPE"] = 'MYSQL';
  $DB["SERVER"] = 'localhost';
  $DB["PORT"] = '3306';
  
  // SQLITE3 use full path to file/database: $DB["DATABASE"] = '/var/lib/zabbix/zabbix.sqlite3';
  $DB["DATABASE"] = 'zabbix';
  $DB["USER"] = 'zabbix';
  $DB["PASSWORD"] = 'root';
  // SCHEMA is relevant only for IBM_DB2 database
  $DB["SCHEMA"] = '';
  
  $ZBX_SERVER = 'localhost';
  $ZBX_SERVER_PORT = '10051';
  $ZBX_SERVER_NAME = '';
  
  $IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG;
  </code></pre>
  
  <h2>zabbix-server-mysql.conf</h2>
  
  <pre><code>...
  # dbc_dbtype: type of underlying database to use
  # this exists primarily to let dbconfig-common know what database
  # type to use when a package supports multiple database types.
  # don't change this value unless you know for certain that this
  # package supports multiple database types
  dbc_dbtype='mysql'
  
  # dbc_dbuser: database user
  # the name of the user who we will use to connect to the database.
  dbc_dbuser='zabbix'
  
  # dbc_dbpass: database user password
  # the password to use with the above username when connecting
  # to a database, if one is required
  dbc_dbpass='root'
  ...
  </code></pre>
  
  <p>I start it with apache server. When I go to localhost/zabbix I see Zabbix Installer. On step 3 it's necessary to configure DB connection. So, here is a problem:</p>

  <p>As you see, in select list is <strong>only</strong> PostgreSQL, so, I can't connect to database (mysql server is running) and go to the next step.</p>
