I need to establish an SSL connection between MySQL server and PHP web application.
Currently we are working with offline server (wampserver) and we need to establish an SSL connection. Th moment I changed the connection script from:
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$conn->exec("SET CHARACTER SET utf8mb4");
To:
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass, array(
PDO::MYSQL_ATTR_SSL_KEY =>'/etc/mysql/ssl/client-key.pem',
PDO::MYSQL_ATTR_SSL_CERT=>'/etc/mysql/ssl/client-cert.pem',
PDO::MYSQL_ATTR_SSL_CA =>'/etc/mysql/ssl/ca-cert.pem'
));
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$conn->exec("SET CHARACTER SET utf8mb4");
an error appeared on the login page saying:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2006] MySQL server has gone away' in C:\wamp64\www\
EDIT
I run this query:
show variables like '%ssl%'
And got the following result:

Please what causes this error, server configurations or laravel configuration? I'd really appreciate if someone offers a solution to this error.
I'm trying to connect to my MySQL DB located on 192.168.23.140 from my Web Frontend on .23.139
Here is my code :
$servername = "192.168.23.140";
$username = "web";
$password = "rootnetwork";
$dbname = "test";
try {
$conn = new PDO('mysql:host=$servername; dbname=$dbname', $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();
}
Here is what i get :
Connection failed: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
I've been looking for some answers on the internet but none of them work.
Thank you for your help
$variables are not expanded in a single quotes string literal, they are only expanded in a double quoted string literals.
So
$conn = new PDO("mysql:host=$servername; dbname=$dbname", $username, $password);
You will also have to make sure that this MYSQL user account web is setup to allow connections from ip addresses that are not the ip of the machine running MySQL
I want to connect to a MySQL database from PHP but I can't because "authentication method unknown", I found many solution but all of them about creating a new user with the old password type, but according to the PHP documentation, it should support the new password type. So is it possible to use the new MySQL password type with PHP 7.2.7?
Versions
PHP: 7.2.7MySQL Server: 8.0.12
PHP Code
// Create connection
$conn = new mysqli($servername, $username, $password);
$conn->set_charset("utf8");
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
Result
Connection failed: The server requested authentication method unknown to the client
I'm having a problem to connect my DB cloud sql with php.
I've tried every possible way to connect (pdo, mysqli & mysql)
none of them worked.
I've put an IPv4 for the could sql instance and authorized the compute engine IP in the allowed networks section.
When I'm trying to connect from the compute engine with
mysql --host=cloud_sql_IP --user=my_user --password
it's working and I'm able to see the tables.
On the php side I've put this code:
$db = mysql_connect(<CLOUD_SQL_IPV4>, 'root', '');
if (!$db){
die('Connect Error (' . mysql_error());
}
and I get "Connect Error (Permission denied)"
when I'm trying this way:
$conn = mysql_connect(":/cloudsql/<COMPUTE_INSTANCE>:<DB>", "root", "");
if (!$conn) {
die('Connect Error (' . mysql_error());
}
I'm getting:
"Connect Error (No such file or directory"
What else should I do?
Thanks!
Well after diggin into it for 2 days I managed to connect cloud DB
first run this for the permission fix (centos)
setsebool httpd_can_network_connect=1
And for the php it should be written this way:
new mysqli(
<IP_V4>, // host
'root', // username
'', // password
<DB_NAME>, // database name
null,
'/cloudsql/<GCE_INSTANCE>:<DB>'
);
Any one plz tell me why i am getting this error ?? firstly my internet connection was good today its not good so i am getting this error.how can i fix this any idea plz??

this is my config.ini
[general]
db.adapter = PDO_MYSQL
db.params.host = 192.168.0.233
db.params.username = root
db.params.password = my_password
db.params.dbname = "mydatabasename"
some code from my index.php
$config = new Zend_Config_Ini(ROOT_DIR.'/application/config.ini', 'general');
$DB = Zend_Db::factory($config->db);
Zend_Db_Table::setDefaultAdapter($DB);
it seems that your code this portion is not working
[general]
db.adapter = PDO_MYSQL
db.params.host = 192.168.0.233
db.params.username = root
db.params.password = my_password
db.params.dbname = "mydatabasename"
either the IP is not correct if so go to cmd in windows and type ipconfig you will get your correct ip paste it here OR just simply write
db.params.host = localhost
if and only if you are using locally may be it works.
for the hostname/host try to use your credentials found in the Zend Server -> PHP Cloud tab -> Overview page -> User Parameters tab... then make the "host" part in the credentials like this:
[general]
db.adapter = PDO_MYSQL
db.params.host = CONTAINERNAME-db.my.phpcloud.com
db.params.username = ZEND_DB_USERNAME
db.params.password = ZEND_DB_USERNAME
db.params.dbname = ZEND_DB_DBNAME
Did you check your mysql database is up?
If you are sure it is, check that your adapters configuration is ok, maybe the host parameter is not properly configured.
