Troubleshooting Your Installation
If you have any problems during the installation of MySQL, the first place you should look is the "Problems and Common Errors" chapter of the MySQL manual, which is located at http://www.mysql.com/doc/P/r/Problems.html.
The following are some common problems:
On Linux/Unix and Mac OS X, incorrect permissions do not allow you to start the MySQL daemon. If this is the case, be sure you have changed owners and groups to match those indicated in the installation instructions.
If you see the message Access denied when connecting to MySQL, be sure you are using the correct username and password.
If you see the message Can't connect to server, make sure the MySQL daemon is running.
When defining tables, if you specify a length for a field whose type does not require a length, the table will not be created. For example, you should not specify a length when defining a field as TEXT (as opposed to CHAR or VARCHAR).
If you still have trouble after reading the manual, sending email to the MySQL mailing list (see http://lists.mysql.com/ for more information) will likely produce results. You can also purchase support contracts from MySQL AB for a very low fee.
