I am getting this error:
Server Response='12154 ORA-12154: TNS:could not resolve the connect identifier specified
I am on Ubuntu 14.04
My environment variables are:
ORACLE_HOME = /usr/lib/oracle/12.1/client64
LD_LIBRARY_PATH = /usr/lib/oracle/12.1/client64/lib
TNS_ADMIN = /usr/lib/oracle/12.1/client64/network/admin
tnsnames.ora and sqlnet.ora are within /usr/lib/oracle/12.1/client64/network/admin
PS: I can connect through sqlplus with:
sqlplus64 user/pass#dbname
This is the code:
<?php
$conn = oci_connect('user', 'pass', 'dbname');
?>
It never worked on that way, what I did was to use Easy Connect string:
$conn = oci_connect('user', 'pass', 'host/servicename'); however the first way should have worked because in another environments it works.
tnsnames.ora file should look as follows
DBNAME=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=YOUR IP ADDRESS)
(PORT=YOUR PORT NUMBER)
)
(CONNECT_DATA=
(SERVICE_NAME=YOUR DBNAMEPROD)
)
)
conn.php file should look as follows
$USERNAME = "hr"; // Login Username
$PASSWORD = "hr"; // Login Passowrd
$DATABASE = "DBNAME"; // Connect string to connect to your database found in tnsnames.ora
$conn = oci_connect($USERNAME, $PASSWORD, $DATABASE);
if(!$conn){
echo "Your Connection Has an error";
}
else{
echo "Your Connection is Successful"
}

I have bought a database MySQL to use on my domain/host.
I can connect to the database via wampserver (localhost) without problems.
But when I am trying to connect to the host website it gives me an error.
Connection failed: Can't connect to MySQL server on 'mysql-******.net' (111 "Connection refused")
My code:
<?php
$servername = "mysql-*********.net";
$username = "username8954";
$password = "dolphyn1235";
$dbname = "animals";
$dbServerPort = "26313";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname, $dbServerPort);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
Any ideas how to solve this?
Check in your MySQL Server configuration files (my.cnf), find bind-address = 127.0.0.1 then comment them with # at the begining of the line. and then restar your MySQL.
I've been trying to upload my PHP MySQL(in Dreamweaver) project to a free web-hosting site.
When I logged in, there is an error that appear in dbconn.php file.
The error is shown below:
and here's the code in my dbconn.php file:
<?php
/* php& mysqldb connection file */
$user = 1350048; //mysqlusername to db
$pass = "password"; //mysqlpassword to db
$host = "eskl.freeoda.com"; //server name or ipaddress
$dbname= 1350048; // db name in server freeoda
$dbconn= mysql_connect($host, $user, $pass);
if(isset($dbconn)){
mysql_select_db($dbname, $dbconn) or die("<center>Error: " . mysql_error() . "</center>");
}
else{
echo "<center>Error: Could not connect to the database.</center>";
}
?>
I would really appreciate if anyone can teach me how to solve this.. thanks in advance!
As Kerbholz already stated, don't use mysql_* functions, they are really outdated.
Instead use mysqli:
$servername = "eskl.freeoda.com";
$username = "1350048";
$password = "password";
$database = "1350048";
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
For your error it got mostly something to do your host doesn't allow remote connections. Try to change the serverhost to localhost or 127.0.0.1
I am new to php/sql and i have a login system which runs on my local host using xammp and it all works fine. I now want to upload it to my website but the code no longer works... I have created a sql db on my hosting service and tried to change the code.
the code that is used on the local host is
<?php
$dbServername = "localhost";
$dbUsername = "root";
$dbPassword = "";
$dbName = "loginsystem";
$conn = mysqli_connect($dbServername, $dbUsername, $dbPassword, $dbName);
and this is the code that i have got from my hosting.
<?php
$host_name = 'db682827654.db.1and1.com';
$database = 'db682827654';
$user_name = 'dbo682827654';
$password = '<Enter your password here.>';
$conn = mysql_connect($host_name, $user_name, $password, $database);
if (mysql_errno()) {
die('<p>Failed to connect to MySQL: '.mysql_error().'</p>');
} else {
echo '<p>Connection to MySQL server successfully established.</p >';
}
?>
however this brings up an errror message. I have changed the password to the password for my database but its still not connecting.
This is the error message.
Failed to connect to MySQL: Access denied for user 'dbo706265806'#'217.160.62.78' (using password: YES)
Any help would be greatly appreciated
use mysqli_connect (not mysql_connect) like localhost:
<?php
$dbServername = "db682827654.db.1and1.com";
$dbUsername = "dbo682827654";
$dbPassword = "<Enter your password here.=)>";
$dbName = "db682827654";
$conn = mysqli_connect($dbServername, $dbUsername, $dbPassword, $dbName);
?>
On your computer you are using mysqli_connect, but on the server you are trying to use mysql_connect. Just use the same file from your computer and simply change $dbServername, $dbUsername, $dbPassword and $dbName to match those that your hosting provided.
I am trying to connect to (remote) AWS MYSQL database using php and ssl.
I created a database user and could connect with it from php and also on console.
Then I modified the user to use SSL with "require ssl" in the database.
I can stil connect on the console by:
mysql -h host -u username -p --ssl
But in php I get an ERROR 2002.
$con=mysqli_init();
mysqli_ssl_set($con,NULL,NULL,"cacert.pem",NULL,NULL);
$link = mysqli_real_connect($con, "host", "username", "password");
As far as I know the ssl_set parameters doesn't matter with AWS databases.
How to connect to Amazon RDS via SSL?
I think it has to do with the mysqli_ssl_set method, without it a connection is made and access is denied by database and this is the correct behaviour. It might be some configuration error on client side, but I have no idea what I shoud check.
The error is fired by mysqli_real_connect, as mysqli_ssl_set always returns true, just after it tries to connect will it receive an error.
I noticed it did not work for me until I specified the port. The following worked:
$db = mysqli_init();
$db->options(MYSQLI_OPT_SSL_VERIFY_SERVER_CERT, true);
$db->ssl_set(NULL, NULL, 'rds-combined-ca-bundle.pem', NULL, NULL);
$db->connect($host, $user, $pass, $db, 3306);
$servername = "only-ssl-db.ct5b4uz1gops.eu-central-1.rds.amazonaws.com";
$username = "username";
$password = "password";
$dbname = "dbname";
$con = mysqli_init();
if (!$con){
die("mysqli_init failed");
}
mysqli_ssl_set($con,NULL,NULL,'rds-combined-ca-bundle.pem',NULL,'DHE-RSA-AES256-SHA');
if (!mysqli_real_connect($con,$servername, $username, $password, $dbname))
{
die("Connect Error: " . mysqli_connect_error());
}
// Some queries...
echo "Database connected";
printf("Client version: %d\n", mysqli_get_client_version());
mysqli_close($con);
I am trying to connect to a mssql server on my mac through pdo_dblib. I have the freetds.conf updated to the host I want to connect. My phpinfo tells me that I have all the driver hooked up and good to go. Below is the code that I wrote to test if I can connect to the server.
<?php
$servername = "IP";
$port = "port";
$username = "username";
$password = "password";
$myDB = "database";
try {
$conn = new PDO("dblib:dbname=$myDB;host=$servername:$port", "$username", "$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();
}
?>
However I get an error:
Connection failed: SQLSTATE[] (null) (severity 0)
I tried using SQL Developer to connect to the mssql server and it worked. I have been trying to solve this problem for a whole day. What might be the problem? Thanks!
Remove the quotes from the variables in the connection string -
$conn = new PDO("dblib:dbname=$myDB;host=$servername:$port", $username, $password);
I found out the answer!
You have to uncomment TDS version protocol in /usr/local/Cellar/freetds/0.91/etc/freetds.conf.
Found the solution in Why won't my server connect to a remote MSSQL server using PHP mssql_connect?
but why do I have to do this...no idea...wish some one could give some explanation.
