I have found that if everything was installed correctly, this happens when trying to test via SSH and via running mysql. It occurs because mysqld is not running. If you try and start that using /etc/rc.d/init.d/mysql start, that fails. The problem is that the /etc/my.cnf file is wrong - probably for an older version like using 4.1 with 5.0. Update it to one of the defaults like my-huge.cnf and start customizing from that base. It should now work.

Regular Expression

Match Until String

Often when processing markup like HTML and XML, the regular expression should match everything upto or until some string occurs, say the string ``gobble. This is achieved by the following regular expression:

(.(?!gobble))*

As an example, we might want to match the first hyperlink that occurs inside a table row. The following is a simple expression that attempts, but fails, to capture this:

<tr>.*<a href="([^"]*)"

The problem is that the table row might be terminated before a matching hyperlink occurs. As the regular expression states, it will match the first hyperlink that follows the start of a table row. As such, that regular expression will match ``somelink.html in the following document.

<tr> .... </tr> .... <a href="somelink.html">link to somewhere</a> ...

The correct way to achieve the desired result is to only match until the end of the table row. This is achieved using the match until syntax as follows:

<tr>(.(?!</tr>))*<a href="([^"]*)"
