Thank you in advance!
Check your config->database.php to ensure the
$db['default']['hostname'],$db['default']['username'],$db['default']['password'],$db['default']['database'] are set correctly.
Anther possibility is you're trying to connect a MySQL server remotely but the server itself is blocking remote connection. So make sure that you are able to connect your mysql database using the same set of host, username, password through Mysql client software such as "MySQL Workbench"
As stated by Tan See Youu, it's likely that you may have incorrect credentials in the database.php or indeed named remote connection is being blocked by the server. Though in some cases hosts offer tunnles to be used to allow remote connections through a secured connection. You might want to ask your hosting if they have a SSH tunnel that you could use if they do block direct connections.
1.Check your application/config/database.php
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost', // your database machine name, this could have localhost, ip address or domain name.
'username' => 'yourmysluser',
'password' => 'yourmysqlpassword',
'database' => 'yourdb',
'dbdriver' => 'mysqli',
Check your mysql database, by default remote access to the MySQL database server is disabled for security reason. However, some time you nee to provie remote access to database server from home or a web server. You can enable remote mysql access with mysql console or phpmyadmin or another database tool dependent your host.
refer to this :
Enable remote MySQL connection: ERROR 1045 (28000): Access denied for user

how to access cpanel database access in godady server using mysql php connectivity
i have tried a lot but last long it gives me
Warning: mysql_connect() [function.mysql-connect]: Lost connection to
MySQL server at 'reading initial communication packet', system error:
111 in /home/content/q/u/i/quickandkosh/html/searchdata.php on line 6
Could not connect: Lost connection to MySQL server at 'reading initial
communication packet', system error: 111
I'm not sure about go daddy but I know some web hosts need a specific path to mysql server. Most us localhost but others, such as ipage use a full path through the virtual server. Go into your cpanel at godaddy and then "mysql databases" and it should have a "server" title with address below it somewhere in the page.
Just to note, you should also be using mysqli_connect.
I think your host could be wrong, wrong port, a firewall blocked the connection. So I would double check your connection settings.
I'm beginning to migrate a software project from being a desktop application to a web application. Currently I am using a local PHP/MySQL connection that is associated with the desktop it is installed on.
I'm hoping to untangle this and am trying to create a MySQL database through my 1and1 account. I had no trouble creating a database and recorded my account information. I'd like to be able to edit this database using PHP scripts on my system. However, I haven't been able to get a working connection string going. When I run the following PHP script:
$hostname="db*********.db.1and1.com";
$database="db*********";
$username="dbo*********";
$password="*********";
$link = mysql_connect($hostname, $username, $password);
I get the following error when I run the script in my webbrowser:
Warning: mysql_connect() [function.mysql-connect]: Unknown MySQL server host 'db*********.db.1and1.com' (11001) in C:\Program Files\xampp\htdocs\Remote_MySQL\rightbid_database_initialize.php on line 74
Connection failed: Unknown MySQL server host 'db*********.db.1and1.com' (11001)
How do I get my local system to recognize the 1and1 server host? Am I structuring my connection string correctly? Is it possible to access a remote server from a locally hosted Windows PHP connection?
Thanks!
I assume what's happening if that 1&1 are blocking any connections coming from outside of their network.
Try connecting using
mysql -h HOST -u USERNAME -p DATABASENAME
Good luck
Make sure the MySQL server on 1and1 will accept connections from remote clients. Not just on localhost, and also make sure port 3306 is open to the server.
I've done a bit of research on this today, but nothing seems to address this issue. I recently upgraded to PHP 5.3.3 from 5.1.6, as well as upgraded MySQL to 5.5 from 5.0. Afterwards, the following code generates an error saying "Can't connect to mysql database":
$connection = mysql_pconnect($dbhost, $dbusername, $dbpassword);
if (!$connection) {
//Can't connect
die('Could not connect: ' . mysql_error());
return;
}
And get the following error:
Warning: mysql_pconnect(): Can't connect to MySQL server on '199.59.157.103' (13) in /var/www/html/ws/Cust/customerWS_1_1.php on line 19 Could not connect: Can't connect to MySQL server on '199.59.157.103' (13)
I am able to connect to the remote host via the command line, and have tried everything from resetting the password to shutting down IP Tables. I'm kind of at a loss - so any help would be appreciated.
We had a similar problem with the same error message "Can't connect to mysql database" and maybe the following points will be also usefull:
check mysql user privileges (in our case and with external connections we had the old server IP address (allow access) in the table) GRANT ALL PRIVILEGES ON tablename.* TO 'username'#'145.1.1.2';
-> reload privileges after changes (FLUSH PRIVILEGES;)
disable the SELinux parameter. In new Plesk versions (>10?) this would be set enabled automatically...
--> in /etc/selinux/config change the line that says:
SELINUX=enforcing to SELINUX=disabled
See further details: http://googolflex.com/?p=482
There is a PHP 5.3 mysql driver restriction related to old authentication scheme hash stored in the database by previous mysql server. This could cause a problem with stored passwords so the databases will be unaccessible with old passwords.
To solve the problem you should recreate the mysql users with the same login and same password.
When you say "I am able to connect to the remote host via the command line" do you mean, you are connecting to the MySQL server REMOTELY? Or that you are SSHing to your MySQL server and connecting to it from the MySQL server's command line? If the latter, it's possible that when you upgraded to MySQL 5.5 you accidentally stopped MySQL from binding / listening on a public IP. Check your my.cnf.
Otherwise: is your PHP code being run on the same server as your MySQL server? It's possible that your permissions could be off. MySQL permissions are very particular about connecting to the MySQL server via it's IP address if the client only has access to connect from 'localhost', and vice-versa.
First you should make sure that the connect parameters $dbhost, $dbusername and $dbpassword are correct. Assuming these are correct, you should check your mysql ini settings. I would assume that the bind-address is set to 127.0.0.1 or localhost, but not to a public IP address.
Also note that it's a security risk if you can connect to mysql from a public IP address. You may want to look into a solution that does not require such connection.
I get this everytime I use mysql_connect() no matter what database I choose:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on 'IP' (111) in filename.php on line 17
A MySQL error has occurred: Can't connect to MySQL server on 'IP' (111)
The exact same file works on my personal website fine. I have tried multiple databases hosted on different servers and it always gives that output.
The database itself is hosted on the same server, but using its full IP in mysql_connect(). Using localhost:port doesn't work either as it says:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in filename.php on line 17
A MySQL error has occurred: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
But using the IP should work as it has worked calling it via the same file hosted on other servers.
This is the code:
$connect = mysql_connect($db_url,$db_user,$db_pass); // connects
if ($connect == false) exit("A MySQL error has occurred: " . mysql_error());
Now since the file works on other servers i am guessing it is something to do with the server it is on and might need something changed. I don't personally have root access to the server (just my part of the shared host). Is there anything I can do i php, editing the php.ini file or something I should pass on to someone with root access?
Edit: Ok it turns out that the server doesn't have access to outside databases, so thats why the IP didn't work. Thanks for all your answers but we have decided simply to change hosting provider. We need to be able to access an outside database.
This is on a hosting service? Check their documentation, there will be something that tells you where to find mysql. It isn't necessarily localhost.
For example, on startlogic.com, you use: yourdomain.startlogicmysql.com
Can you connect using mysqladmin using the same host, username and password?
mysqladmin -h $db_url -u $db_user -p $db_pass
Replace $db_xxxx with real values.
If that works from the same host as your php script, then sudo to the apache User and try the same test. One of those must be failing.
EDIT: nevermind on sudo part, I noticed that you don't have root access.
Something else to try: Use '127.0.0.1' instead of 'localhost'. I have had issues before where mysql stupidly assumed it could silently change 'localhost:' to '/var/run/mysqld/mysqld.sock'.
Your wording is not very clear, I hope you are not thinking you can connect to the same mysql server from any old web server just because you know the IP address and port number. If the web host is at all competent, they have probably firewalled mysql so it is only accessible through their own web servers.
I have a system with a globally open mysql connection to the local server. In one of my files I am opening an additional connection to a remote machine.
Wieldly instead of trying to connect to that machine, I get an access denied message from my ISP (it seems to be trying to connect to the database on that machine).
I am trying to connect using:
$cust_conn = mysql_connect($host,'root','##password##');
I have tried subdomain.domain.com:3306, subdomain.domain.com and ip:3306 as the value for $host.
The wierd this is the response i get:
Warning: mysql_connect(): Access denied for user 'root'#'my.isp.com' (using password: YES) in /var/www/html/report/module/sql_view.php on line 19 Error: Could not connect to database:
Any ideas why this would happen? It seems like for some reason my script is attempting to connect to my ISPs server, instead of the one passed in $host.
The host given in the error message is the host it's trying to connect from, not to.
that hostname in the error (my.isp.com) is your client's host...remote root access is often disabled, or perhaps the pass/host combo is wrong
