I'm trying to create a connection to a local Database Server through a VPN connection first.
From the VPN connection I receive this IP for my network:
192.168.30.2
DB-Server:
192.168.40.150
If I try to ping the DB Server IP via PHP, I also get a response from the Server. When, however, I try to make the PDO connection or with "mysqli", I receive the following error:
lluminate \ Database \ QueryException: SQLSTATE [HY000] [1045] Access denied for user 'xxxx'#'192.168.30.2' (using password: YES) (SQL: select * from `xxxx`) in file
If I use a Mysql Client from my PC it's working fine!
Any idea?
SOLVED: the DB server required a SSL Connection (without Cert). These options was required in the PDO connection:
PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT
PDO::MYSQL_ATTR_SSL_CA
If you use Laravel Illuminate for the connection you need to declerate the options in the connection, example:
...
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => env('MY_SSL_VERIFY', ' '),
PDO::MYSQL_ATTR_SSL_CA => env('MY_SSL_CA', ' '),
]) : [],
...
In this case is really important to give a Value with empty space ' ' otherwise will the Illuminate PDO Connector not get the option values.

I am trying to use a PHP connection to connect MySQL Database which is on phpmyadmin. Nothing fancy about the connection just trying to see whether the connection is successful or not. I am using MAMP to host the database, the connection I am trying to use is this:
<?php
$servername = "127.0.0.1";
$username = "root";
$password = "root";
try {
$conn = new PDO("mysql:host=$servername;dbname=AppDatabase", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
?>
I have been using postman to test to see if the connection is working, but I keep receiving this error message:
Connection failed: SQLSTATE[HY000] [2002] Connection refused
Before I was receiving an error message of:
Connection failed: SQLSTATE[HY000] [2002] No such file or directory
This was because I had set the servername to localhost, through changing this to the IP address it has given me connection refused and I have no idea what is wrong.
Any help regarding this would be appreciated.
I found the reason why the connection was not working, it was because the connection was trying to connect to port 8888, when it needed to connect to port 8889.
$conn = new PDO("mysql:host=$servername;port=8889;dbname=AppDatabase", $username, $password);
This fixed the problem, although changing the server name to localhost still gives the error.
Connection failed: SQLSTATE[HY000] [2002] No such file or directory
But it connects successfully when the IP address is entered for the server name.
In my case MySQL sever was not running. I restarted the MySQL server and issue was resolved.
//on ubuntu server
sudo /etc/init.d/mysql start
To avoid MySQL stop problem, you can use the "initctl" utility in Ubuntu 14.04 LTS Linux to make sure the service restarts in case of a failure or reboot. Please consider talking a snapshot of root volume (with mysql stopped) before performing this operations for data retention purpose[8]. You can use the following commands to manage the mysql service with "initctl" utility with stop and start operations.
$ sudo initctl stop mysql
$ sudo initctl start mysql
To verify the working, you can check the status of the service and get
the process id (pid), simulate a failure by killing the "mysql"
process and verify its status as running with new process id after
sometime (typically within 1 minute) using the following commands.
$ sudo initctl status mysql # get pid
$ sudo kill -9 <pid> # kill mysql process
$ sudo initctl status mysql # verify status as running after sometime
Note : In latest Ubuntu version now initctl is replaced by systemctl
I spent quite a few hours in a docker environment where all my containers are docker containers and I was using Phinx for migrations. Just to share different responses with different configurations.
Working solutions
"host" => "db", // {docker container's name} Worked
"host" => "172.22.112.1", // {some docker IP through ipconfig - may change on every instance - usually something like 172.x.x.x} Worked
Non-working solutions
"host" => "127.0.0.1", // SQLSTATE[HY000] [2002] Connection refused
"host" => "docker.host.internal", // SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name does not resolve
"host" => "localhost", // SQLSTATE[HY000] [2002] No such file or directory
I was running Phinx in following way.
docker compose --env-file .env run --rm phinx status -e development
Using MAMP I changed the host=localhost to host=127.0.0.1. But a new issue came "connection refused"
Solved this by putting 'port' => '8889', in 'Datasources' => [
Using MAMP ON Mac, I solve my problem by renaming
/Applications/MAMP/tmp/mysql/mysql.sock.lock
to
/Applications/MAMP/tmp/mysql/mysql.sock
1. server cert verify flag
I was required to use SSL to connect, and needed to set PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT to false in the new PDO options array, besides the entry PDO::MYSQL_ATTR_SSL_CA for the CA file.
Without it, the mysql log on the server helpfully mentions
2021-07-27 17:02:51 597605 [Warning] Aborted connection 597605 to db: 'unconnected' user: 'unauthenticated' host: '192.168.10.123' (This connection closed normally without authentication)
where I was definitely passing the right db and username and such in the DSN. An empty options array will show the db and user in the error log, at least. I am sure there is a valid, technical reason for these things.
I am adding this information so I can more easily find it, the next time I end up on this page..
2. host in connection string
In the context of SSL, I've also seen the error when using the IP address instead of the hostname to connect, if the hostname was used as CN (Common Name) in the certificate.
For me was php version from mac instead of MAMP, PATH variable on .bash_profile was wrong. I just prepend the MAMP PHP bin folder to the $PATH env variable. For me was:
/Applications/mampstack-7.1.21-0/php/bin
In terminal run vim ~/.bash_profile to open ~/.bash_profile
Type i to be able to edit the file, add the bin directory as PATH variable on the top to the file:
export PATH="/Applications/mampstack-7.1.21-0/php/bin/:$PATH"
Hit ESC, Type :wq, and hit Enter
In Terminal run source ~/.bash_profile
In Terminal type which php, output should be the path to MAMP PHP install.
I had the same issue on a docker container from php:8.0-fpm-alpine image. I just added the following line in the Dockerfile and it fixed the issue:
RUN apk add mysql-client
I had a similar problem once, turned out the User in the database was created with something like:
CREATE USER 'webpage'#'localhost' IDENTIFIED BY 'password';
worked fine when the connection details php script had localhost, but not when the IP address was there. A quick swap (ip address when creating user and localhost in connection details) revealed those two things have to match.
For everyone if you still strugle with Refusing connection, here is my advice. Download XAMPP or other similar sw and just start MySQL. You dont have to run apache or other things just the MySQL.

I'm trying to connect from PHP PDO to Amazon's PostgreSQL DB instance using SSL. I'm using the following DSN:
$db = new PDO('pgsql:host=[host];port=[port];dbname=[db];options=\'--client_encoding=utf8\';sslmode=require;sslcert=/path/domain.crt;sslkey=/path/private.key;sslrootcert=/path/intermediate.ca-bundle;', '[user]', '[pass]');
I'm using the same sslcert, sslkey and sslrootcert that are used by Apache on the same client server - they are in PEM format. I can connect using SSL to MySQL with them using following PDO options.
$options = [
PDO::MYSQL_ATTR_SSL_KEY => '/path/private.key',
PDO::MYSQL_ATTR_SSL_CERT => '/path/domain.crt',
PDO::MYSQL_ATTR_SSL_CA => '/path/intermediate.ca-bundle',
PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => true,
];
But for PG, I'm getting:
SQLSTATE[08006] [7] SSL error: certificate verify failed
Without SSL, I can connect with no problem.
Any help would be appreciated!
I am using mongoDB with PHP. on local system it works fine. Now I am trying to access mongoDB cluster on AWS which is secured by SSH. I am using below code
$conn = new MongoClient('mongodb://SSH Hostname', [
'username' => 'username',
'password' => '',
'db' => 'DBname'
]);
print_r($conn);
It gives below error
Type: MongoConnectionException
Message: Failed to connect to: SSH Hostname :27017: Connection refused
I can connect DB from MongoDB compass or Studio 3T. How I can use SSH while connecting using PHP
So, my app is on this link
I am able to create a tunnel using Pagoda client and I can view databases via the mySQL CLI.
That command being mysql -u<DBusername> -p<DBpassword> -htunnel.pagodabox.com -P<the port tunnel shows me to connect on e.g. 3306>
The app works locally. Okay, further i've searched and searched, did the app/database.php configuration, checked the socket, it's okay too, at /var/run/mysqld/mysqld.sock .
The error is this:
In my Boxfile, I have this before-deploy hook before_deploy:
- "php artisan migrate:install --env=production"
This causes the [PDOException] SQLSTATE[HY000] [2002] No such file or directory and hence it isn't deployed.
Any help\reference would be really welcome. Any more info can be given too. Cheers!
Modified the mysql configuration in my app/config/database.php to this:
'host' => isset($_SERVER['DB1_HOST']) ? $_SERVER['DB1_HOST'] : '127.0.0.1',
'database' => isset($_SERVER['DB1_NAME']) ? $_SERVER['DB1_NAME'] : '<db_name>',
'username' => isset($_SERVER['DB1_USER']) ? $_SERVER['DB1_USER'] : '<mysql_username>',
'password' => isset($_SERVER['DB1_PASS']) ? $_SERVER['DB1_PASS'] : '<mysql_password>',
That solved my problem!
