yii2 with oracle and gii error

[PyPiMe]

• Local:CentOS-7.4.1708
• Local:PHP-7.1.11
• Remote:Oracle 11g-11.2.0.4.0
• Local:oci8-2.1.8
• Local:Nginx-1.13.8
• Local:Yii2-2.0.13

I can connect remotely to DB with sqldeveloper. I can connect with sqlplus to DB.I can successfully run the following code and get the correct result

<?php
// demo.php
$username = 'user';
$password = 'pwd';

$connectText = '//remoteip:1521/test';

putenv("NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK");
$conn = oci_connect($username, $password, $connectText);
if (!$conn) {
    $e = oci_error();
    echo 'Oracle connect false<br />';
    exit($e['message']);
}

echo 'Oracle cnnectted';

// Prepare the statement
$stid = oci_parse($conn, "SELECT * FROM CODE_XSB");
if (!$stid) {
    $e = oci_error($conn);
    exit($e['message']);
}

// Perform the logic of the query
$r = oci_execute($stid);
if (!$r) {
    $e = oci_error($stid);
    exit($e['message']);
}
// Fetch the results of the query
print "<table>\n";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
    print "<tr>\n";
    foreach ($row as $item) {
        $item = ($item !== null ? mb_convert_encoding($item, 'utf-8', 'gbk') : " ");
        print "    <td>" . $item . "</td>\n";
    }
    print "</tr>\n";
}
print "</table>\n";
oci_free_statement($stid);
oci_close($conn);

But I can't make gii to work.

main-local.php
'oracledb' => [
            'class' => 'yii\db\Connection',
            'dsn'=>'oci:dbname=//remoteip:1521/test;charset=utf8',
            'username'=>'user',
            'password'=>'pwd',

I got following error message:

Database Exception – yii\db\Exception
could not find driver
↵
Caused by: PDOException
could not find driver

in /home/www/devnet/Yii2/vendor/yiisoft/yii2/db/Connection.php at line 660

Means either you don't have PDO driver installed/enabled in php.ini or you're specifying DSN incorrectly.
