    Can't verify MySQL DataSource

    ronuś Community Member

      Hi There,

       

      I've got problem with setting up a new DataSource on MySQL 4/5 driver. From the beginning:

       

      1. I've installed ColdFusion 9 (Developer Edition), with JRun 4 option. I've done configuration of Apache (conf file, and execution file)

      2. When i want to set up new DataSource with MySQL 4/5 driver, i'm getting error.

       

      For Example:

       

           CF Data Source Name:      MyDataSource

           Database:                         MyBase

           Server:                              localhost

           Port:                                 3306

           Username:                        user

           Password:                         password

       

      After that. I have information:

      Connection verification failed for data source: MyDataSource
      
      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.
      

       

       

       

      The, in DataSource menu in Administration i see that base, but with this error under entry with name of DataSource.

      What i'm doing wrong?

      I have tried to install MangoBlog, but i can't do this with that issue. When i try, i get:

       

      Could not find the ColdFusion component or interface CFIDE.scripts.MangoBlog_1.4.1.components.utilities.PreferencesFile.
                  
      
      

       

      I think it's about that error which i've described.

      Anyone got some ideas to this ?

       

      Greets,

      Rafal

          CF can not open a TCP socket to the database server. Check that the database server is actually running, listening on port 3306 and not locked by a firewall. If you have IPv6 enabled on your system, try 127.0.0.1 instead of localhost.

            Are there any processes that might be claiming all the connections to the database?

              A connection limit in MySQL that is exhausetd should give a different error since then you would essentially connect and be disconnected.

                A connection limit in MySQL that is exhausetd should give a different error since then you would essentially connect and be disconnected.

                Why presume that, when you're told there were 3 attempts to reconnect?

                 

                Ronski87, you can eliminate the connection-limit hypothesis by doing the following in the Administrator:

                1) For that particular datasource, choose to Show Advanced Settings. Enter this query in the field Validation Query:

                set @@global.max_connections = 1000;

                2) Press the button to submit the changes.

                3) Is the datasource now verified?

                 

                If not, my next bet will be one of Jochem's ideas, a firewall block.

                  Maybe this KB or this KB will help you...

                    Thanks for all reply's

                     

                    I've tried to make with your suggestions, that means with Your suggestion BKBK -> still the same error.

                    Alexei -> this .jar's neither.

                     

                    I downloaded Advanced Port scanner to test port's status. Every time (is firewall on or not) i have 3 to 5 ports opened (23 - telnet, 25 - smtp, 80 - www, 110 - pop3). Rest is blocked. I work on laptop, but situation with my standalone PC looks the same -> all ports are blocked, excepts this few.

                      You need security, but this is all-borders-closed dictatorship.

                      You should configure the firewall to allow MySQL on port 3306.

                        Hi there again.

                         

                        sorry guys (and girls if any ofc), i'm so stupid...

                         

                        the only problem with my issue was that, i didn't set up new database in phpmyadmin (using MySQL). Now, i set new one, set user, password and... everything works fine.

                         

                        sorry for that, human is learning for all the time

                         

                        I want to thank everybody who helps me with posting, and see You again in the next issue

                          I have the same problem as you. Can you explain what you mean by "set up new database in phpmyadmin (using MySQL". I am using Dreamweaver CS4.

                            Hi, if You want to use DataSource with MySQL driver, you have to SET UP a new database via phpMyAdmin. It is a tool which with you can add and make everything you want with MySQL databases. Setting it up, adding new tables, edit tables and more. I'm using WAMPP (Apache, MySQL, PHP) - a windows web development environment. here yoe've got the link:

                             

                            http://www.wampserver.com/en/download.php

                             

                            If You have more questions, write here or send me pm.

                              You don't need to use PHPMyAdmin to do this.  PHPMyAdmin is just a web-based DB client.  MySQL does come with its own GUI management tools.  Or indeed one can just connect to the server on the command-line and do anything you like that way too ;-)

                               

                              My impression of PHPMyAdmin - although I've not used it for 7-8yrs - was that it was to a proper GUI tool what Outlook Web Access is to MS Outlook: a rather poor cousin.

                               

                              But - yes - to create a working CF DSN, there does have to be a database to connect to first, so one does need to create it if it doesn't already exist!

                                I found the problem. Both IIS and PHP use port 80. I thought I had uninstalled IIS but had not.

                                  Hi,

                                   

                                  I'm having exact same issue.

                                   

                                  Am able to connect via DW with PHP and everything works fine, then try connecting via CF9 Administration to the same database as PHP, I get same error message as above, then try connecting via DW with CF the error message is saying "access denied"

                                   

                                  Environment is;

                                  OS X 10.6.2 64 bit

                                  MAMP Pro 1.8.4

                                  CF 9 Developer Edition

                                  MySQL

                                   

                                  One thing I have notice is that CF 9 installer produced error log and when reviewing couldn't identify any issues and all seems to be working fine except connecting to MySQL.

                                   

                                  Can anyone assist?

                                    You can try checking mySQL user settings in DB mysql TABLE user

                                     

                                    In field "host" of your user  CF requires to have "localhost". Some SQL shell (like the old gui tools of myMySQL) will set this field to "%".

                                     

                                    NB: setting to "localhost" you will no more able to access remotely with that user. You may want to duplicate the row.

                                      Tried your suggest and unfortunately still the same issue, works with PHP but not CF.

                                        Problem solved! 

                                         

                                        After some process of elimination, I worked out that MAMP Pro uses different install of mySQL to MAMP.....

                                         

                                        All I had to do is (In MAMP PRO, File -> Edit Template ->MySQL my.cnf) Find MAMP_skip-networking_MAMP and then remove or comment out this line) then restart all service.

                                          I've got the exact same issue, but I didn't install mysql with MAMP Pro but through macports. I've verified the location of my socket and mysql is up and running fine, listening on port 3306 and seems to accept both TCP/IP connections as well as through the socket.

                                           

                                          I am on Mac OS Snow Leopard 10.6.3, running Coldfusion 9 and MySQL 5.1.47. The exact message I am getting when I try to verify the DSN from the Coldfusion Administrator is:

                                          Any insight into why I can't connect? All the online forums seem to suggest that it's the JDBC driver, but I am reluctant to replace the driver until I am absolutely sure that is the problem, since it might have other repurcussions.

                                                  I had the same problem with CF 11 and CF 10 on Mac, running Mysql with MAMP Pro. What I did in the end was a combination of these steps, I don't know if all are necessary but at least it works now

                                                   

                                                  1. In MAMP pro go to -> file > edit template > MYSQL my.cnf (after you shut down the server)

                                                  2. Comment out MAMP_skip-networking_MAMP

                                                  3. Added: max_connections = 1000 (in section [mysqld])

                                                  4. Restart server in MAMP

                                                  5. In CF datasource I changed server settings to 127.0.0.1 port 3306
