MYSQl Connectivity in Linux

i am using redhat linux ee 4. mysql is integrated in it. i also have jdbc connector j. is there any additional softwares needed to connect java with mysql

I know that Red Hat comes with MySQL. Still I usually obtain a newer version from the download area of the mysql website, though I can't recall if it was necessary. It sounds like you have the driver. Have you tried to write a simple database connection class in java to see if you could connect.. Have you been getting any errors... Did you include the jar file for the driver on the classpath...

Need help with MySQL connection error _mmServerScripts

Trying to create insert a recordset I got the message:
"The files from the _mmServerScripts folder are for the server model PHP-MySQL. You try to connect to a database using a different server model .Please remove this folder outside the Dreamweaver environment on both local and testing machines and try again."
I've searched the net and have seen this message hunting people since dw8...
I could not find a "cure".
Things to notice:
0 - Yes the whole thing is apache/php/mysql... just DW thinks it's not.
1 - Both the connection and the Recordset actualy works. I have a whole site based on this connection and the recorsets I've created manualy based on it.
2 - It does not matter if we erase or not the _mmServerScripts folder the message stands still allover.
3 - The problem seems to show up when you split servers...
3.1 - If I test in a WAMP environment where apache and mysql are in the same machine I can use DW to create data objects for me.
3.2 - If I test in my real test environment which have web server and db server separated from each other then I can't use DW to create data objects, see bindings, behaviours etc... all I get is this message.... while the code itself runs fine anyway.
Does any one already knows how to work around or fix this?
Thanks,
Julio

Thanks PZ,
Yes everything is fine with the site definition.
everything works. I can upload, run, test all ok.
The only thing that does not work is to insert any sort of data object through DW interface. If I declare my reordsets by hands or even If I use the ones DW created in my local test server all works fine.
Then if I use the site definition and try to see any bindings or create a recordset or create a new connection using dw... then the messages come up and dw can't go any further in that task.
By spli servers I mean one phisical linux server with apache/php but without mySQL + one physical Linux server with mySQL but without apache/php.
So when I use a site definition that points either to a WAMP or LAMP i.e. when everything is in the same machine DW goes happy and does whatever it's asked to do.
When I try that on the real mccoy environment (with the two separated servers)... It looks like DW gets confused...

PHP and MySQL Connection problem

I am trying to make a PHP MySQL on a remote server connection in Dreamwesaver CS3.
When I enter the information (host, user, password, etc.) and hit TEST, I get the following error message.
"Access Denied. The file may not exist, or there could be a permission problem. Make sure you have proper authorization on the server and the server is properly configured."
I know the user, password, etc. work, as I can access the MySQL database with other software.
I checked with my host and they say there are no permission problems on their end.
I have checked the settings on the Test Server page in Site Setup and everything looks correct and works there.
I have not seen this particular problem described in other forum postings (although there are a LOT of postings on this topic!).
Any help would be appreciated.

I thought my testing server was the remote server and is always on as far as I know. I don't know how to turn it on or off.
Is there some other testing server that I should be aware of?

I know you are using remote, but is your testing server on? if not turn that on and see if that does it. it just happened to me working on remote server and could not get mysql conn to work, until I turn on my testing (developer server), then I was able to connect to mysql and the tables that I created in phpmyadmin remotly was downloaded.

Getting an error in JDBC mySQL Connection

Hi,
I am creating JDBC mySQL Connection error.
The eror messsage is
Incorrect name parameter jdbc:mysql://10.114.16.70:3306/kaushikb root,pass in naming operation.where root is the username and pass is the password and kaushikb is the database name.
I am entering the tablename as: emptable.

Edited by: Taton on Dec 11, 2008 3:15 PM

Let me guess: you did
getConnection("jdbc:mysql://10.114.16.70:3306/kaushikb root,pass");rather than
getConnection("jdbc:mysql://10.114.16.70:3306/kaushikb", "root", "pass");

J2EE mysql connection pool

Hello,
I am trying to create a mysql connection pool using the admin console. The mysql JDBC driver is located in <install_dir>/domains/domain1/lib/ext.
For Datasource Classname I use com.mysql.jdbc.jdbc2.optional.MysqlDataSource
A ping results in:
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection could not be allocated because: null, message from server: "Host 'localhost.localdomain' is not allowed to connect to this MySQL server"
When changing the URL property to localhost a ping results in:
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection object cannot be null
Any ideas about what goes wrong?
Thanks...

I did a simple php test:
<?php
mysql_connect("localhost.localdomain", "user", "pass") or die(mysql_error());
echo "Connected to MySQL<br />";
?>
This results in:
Warning: mysql_connect(): Host 'localhost.localdomain' is not allowed to connect to this MySQL server in /var/www/mathesis/mambo/mysql.php on line 2
Host 'localhost.localdomain' is not allowed to connect to this MySQL server
<?php
mysql_connect("localhost", "user", "pass") or die(mysql_error());
echo "Connected to MySQL<br />";
?>
results in: Connected to MySQL
So I see two possible solutions:
1) Make the appserver use localhost instead of localhost.localdomain (specifying localhost as property doesn't work!).
2) Make MySQL accept localhost.localdomain connections.
For both possible solutions I'm searching for answers...

No Tables in DW CS3 Remote MySQL Connection

Hello All,
I was hoping forum members would be able to troubleshoot a
Dreamweaver CS3/remote MySQL Connection issue I'm having.
I am successful in connecting to the database but the table
data I created in phpMyAdmin 2.6.3 does not appear in the
Application/Databases menu in DW. Instead of the name of the table,
I get "none".
Since I am new to databases, any help is greatly appreciated.
I did view older posts before submitting this one but the advice
recommended (re-installing the entire MySQL application from
scratch) is not an option. Server is SunOS running PHP 4.4.7 and
MySQL 2.0.20. I'm on Windows XP. Thanks once again.

Was this issue resolved?
I have the same problem now. DW was working fine the one day and the next when I started it it had this connection problem.
I am testing on my local PC. My sites is at http://localhost/
All my connection are working because if I go to http://localhost/index.php I can see my site and if I go to http://localhost/register.php I can even register a new user. It will include the new user details in the data base and everything is working fine. So there is nothing wrong with the connection.
In DW I do have http://localhost/ on the Local Info screen. As I said, all was working fine on the current setup the one day and the next day it did not want to work.
Seems like a very common problem.
I want to buy CS4 and surely hope that the problem has been fixed by now.

Cannot connect from dreamweaver cs5.5 to mysql using the mysql connection wizard

Cannot connect from dreamweaver cs5.5 to mysql using the mysql connection wizard error Http error 403 or 500 internal server error. I am using ubuntu mysql.
a manual php script work fine
<?php
// open connection to mysql server
$dbc = mysql_connect('localhost','root','password');
if (!$dbc) {
die('Not Connected' . mysql_error ());
//select database
$db_selected = mysql_select_db ("msinventory",$dbc);
if (!$db_selected)
die('Cannot Connect' . mysql_error());
echo "TEST DONE1";
?>
but the database connection wizard fails with http error 403 or 500
i also use the HeidiSQL client and it works, the only problem is in dreamweaver.

OK. Did you really mean to ask this question on a ColdFusion forum, if it's DreamWeaver you're having problems with? You're probably better off raising this on a DreamWeaver forum. "Using the correct tool for the job" 'n'all.

Class.forName("org.gjt.mm.mysql.Driver";
con = DriverManager.getConnection("jdbc:mysql:///db?user=root&password=");
Try it out!
Queries regarding this is welcome. Either in this forum itself or u can contact in the mail, the id is

Auto mySQL connectivity(Username and Password)

Hey guys!
Good Day!
I have something to ask if possible to java and mySQL connectivity.
I have project that connects to mysql but im using this:
"+con1 = DriverManager.getConnection("jdbc:mysql://localhost/POS_Database","root", "12345");+"
Now, how to auto config the mysql connection not setting the username and password in the project? It configure whatever the settings of mySQL (username and password).

you will have to have the user name and password someware. If not in the code. You casn put them in a file and read it in the code.
Another thing that you can do is to make every user account of your software a valid user in the database. So when the user logs in to software users user name and the password is what you have to use to connect to database. But that will create a bit of a administrative overhead and also it will make it deficult to use connection pooling.

Not able to connect Azure Linux Virtual Machine with Putty

Hi,
I am not bale to connect Azure Linux Virtual Machine with Putty... Error shows "Network error: connection timed out".
Please help.
Thanks,
Techsol
Thanks, Kk

Hi TechSol01,
Thanks for posting here.
I suggest you to try the below steps
On a computer running a Windows operating system, you might want to use an SSH client such as PuTTY. For more information, see the
PuTTY Download Page.
On a computer running a Linux operating system, you might want to use an SSH client such as OpenSSH. For more information, see
OpenSSH.
If it is the endpoint configuration, you can go to the portal and add port 22, (it should already be there by default).
Now if it is locked out of the VM because of the firewall on the VM, which is called iptables , You won't be able to connect to the VM,
If you haven’t configured the port 22. You may have to follow the below steps :
A = Original VM (Inaccessible VM)
B = New VM (New Temp VM)
1) Stop VM A via the Azure management portal
2) Delete VM A BUT select “keep the attached disks”
3) Once the lease is cleared, attach the Data Disk from A to VM B via the Azure Portal, Virtual Machines, Select “B”, Attach Disk
4) On VM “B” eventually the disk will attach and you can then mount it.
5) Locate the drive name to mount, on VM “B” look in relevant log file note each linux is slightly different.
grep SCSI /var/log/kern.log (ubuntu)
grep SCSI /var/log/messages (centos, suse, oracle)
6) Mount the attached disk onto mountpoint /tempmount
df -h
mkdir /tempmount
mount /dev/sdc1 /tempmount
df –h
7) Now you should be able to clear the rules set from the configuration file of the firewall, by accessing it
through /tempmount
Let me know if this works

What's wrong with this MySQL connection? "Could not create connection to database server"

I'm able to connect to other MySQL databases but this one particular remote MySQL connection isn't working and I cannot figure it out. It probably has something to do with the remote server, not CF, but I thought I'd post it here if anyone had an idea. The MySQL account has full priviledges.
Here is the message when I try to validate the data source:
Connection verification failed for data source: test
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.
The root cause was that: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

This happened on two servers. One one, the cause was that skip-networking was turned on. In the other situation, it appears that the database name was case sensitive, so TEST was not the same as test. Even though I edited the data source in the CF administrator, it still didn't work (very misleading). When a coworker entered a new data source with the same information (uppercase database name this time from the start), it worked.
Has anyone else seen this problem with the case sensitive database names? And with the data source in CF not updating the case correctly? Seems like a bug in CF.

MySQL Connection - Select Database - HTTP Error Code 405 Method Not Allowed?

We've set up a MySQL database with our host and can connect to that, and create, edit, delete tables using HeidiSQL, without a problem.
However when we attempt to set up the connection in the Databases tab of our Applications panel in Dreamweaver we receive the following error:
HTTP Error Code 405 Method Not Allowed
We have entered the following in the MySQL Connection box:
Name: <name of our connection>
Server: <IP address of our database>
Username: <our database username>
Password: <our database password>
Database:
When we click the "Select" option next to the Database field, that's when we receive the above mentioned error.
We noticed that there was a fix posted by Adobe at:
http://www.macromedia.com/support/dreamweaver/ts/documents/err405.htm
...but that link is long since dead, however it does seem to indicate that Adobe are/were aware of this issue.
Can anyone help? We're trying to move from Classic ASP / MSSQL to PHP / MySQL but have hit a barrier right from the off, which isn't very encouraging. Hope someone can ease our concerns with PHP and MySQL.
Much appreciated.

Thank you SnakEyez02.
I had the Testing Server set to Local/Network but didn't have MySQL installed locally. Changed that setting to FTP and it picked up on the database correctly.
When using MSSQL it doesn't matter whether you choose Local/Network or FTP it just picks up the online database regardless. I guess this must just be a difference between it and MySQL.
Thanks for the advice. Much appreciated.

Mysql connect

I have been using Dreamweaver 8 for about a month (previously

I can't make a mysql connection as well as open help section.
The help section freezes then closes Dreamweaver
The mysql conn throws this error:
can't connect to local mysql server through
socket;/var/lig/mysql/mysql/sock'(2)
What has happened, this worked fine a few days ago?
Thanks for any help.

If you're using a local testing environment, it sounds as
though the
MySQL server has stopped running on your Mac.
