Bugzilla安装后忘记管理员用户名和密码，如何重新设定？

空想家de白日梦

Bugzilla的官网上的文档是这么说的：
If for some reason you delete the "super user" account, re-running checksetup.pl will again prompt you for this username and password.

这是官网链接：http://www.bugzilla.org/docs/3.4/en/html/useradmin.html

可是当我重新执行checksetup.pl ，只得到如下输出，并未提示我重新设定管理员帐号和密码，这可如何是好？

-------以下为输出结果--------------------

COMMANDS TO INSTALL OPTIONAL MODULES:

       XML-Twig: /opt/lampp/bin/perl install-module.pl XML::Twig
     PerlMagick: /opt/lampp/bin/perl install-module.pl Image::Magick


To attempt an automatic install of every required and optional module
with one command, do:

  /opt/lampp/bin/perl install-module.pl --all

Reading ./localconfig...

OPTIONAL NOTE: If you want to be able to use the 'difference between two
patches' feature of Bugzilla (which requires the PatchReader Perl module
as well), you should install patchutils from:

    http://cyberelk.net/tim/patchutils/

Checking for           DBD-mysql (v4.00)   ok: found v4.013

Removing existing compiled templates...
Precompiling templates...done.
Fixing file permissions...

Now that you have installed Bugzilla, you should visit the 'Parameters'
page (linked in the footer of the Administrator account) to ensure it
is set up as you wish - this includes setting the 'urlbase' option to
the correct URL.

可能上面的解决方案，需要一个前提，就是“super user” account被删掉了，而我的其实没有删掉，而是不记得了；
问题换一下：如何删掉现有的“super user” account？？
