使用phpseclib通過SSH通過MySQL連接的PHP代碼

Question

我想連接到服務器上的MySQL，但是只能使用SSH訪問服務器。 我使用phpseclib連接SSH。 它成功了。 但是當嘗試連接到MySQL時，它說：訪問被拒絕。 所以，我有這些代碼。 有人請幫助我。

<?php

//data for connection to SSH
//host : 10.81.229.31
//user : root
//pass : abcde

//here's data for connection to MySQL
//host = 10.81.229.31
//username = root
//password = abcde
//database name = testing


include('Net/SSH2.php');

//connecting to server with SSH
$ssh = new Net_SSH2('10.81.229.31');

if (!$ssh->login('root', 'abcde')) {
    exit('Login Failed');
}else{
    echo "Login Success";
}

//connecting to MySQL
echo $ssh->exec('mysql -h 10.81.229.31 -u root -p testing');

?>

Answer 1

當您在框內使用ssh時，應將數據庫引用為localhost

echo $ssh->exec('mysql -h localhost -u root -ptesting');

Answer 2

嘗試不帶空格。 例如。

echo $ssh->exec('mysql -h localhost -u root -ptesting');

引用“ man mysql”：

--password [=密碼]，-p [密碼]

Answer 3

<?php

//data for connection to SSH
//host : 10.81.229.31
//user : root
//pass : abcde

//here's data for connection to MySQL
//host = 10.81.229.31
//username = root
//password = abcde
//database name = testing


include('Net/SSH2.php');

//connecting to server with SSH
$ssh = new Net_SSH2('10.81.229.31');

if (!$ssh->login('root', 'abcde')) {
    exit('Login to Server Failed');
}else{
    echo "Login to Server Success";
}

//connecting to MySQL
if (!$ssh->exec('mysql -u root -ptesting \r\n')){
    exit('Login to MySQL Failed');
}else{
    echo "Login to MySQL Success";
}

?>

\\ r \\ n用於回車，結果：

Login to Server SuccessLogin to MySQL Success
