Here are a few recommendations I can give you:
phpMyAdmin
phpMyAdmin is a free software tool
written in PHP intended to handle the
administration of MySQL over the World
Wide Web. phpMyAdmin supports a wide
range of operations with MySQL. The
most frequently used operations are
supported by the user interface
(managing databases, tables, fields,
relations, indexes, users,
permissions, etc), while you still
have the ability to directly execute
any SQL statement.
Webmin
Webmin is a web-based interface for
system administration for Unix. Using
any modern web browser, you can setup
user accounts, Apache, DNS, file
sharing and much more. Webmin removes
the need to manually edit Unix
configuration files like /etc/passwd,
and lets you manage a system from the
console or remotely.
MySQL Workbench
MySQL Workbench is a cross-platform,
visual database design tool developed
by MySQL. It is the highly anticipated
successor application of the
DBDesigner4 project. MySQL Workbench
is available as a native GUI tool on
Windows, Linux and OS X in different
editions.
Navicat
Navicat for MySQL is a powerful
Database administration and
development tool for MySQL. It works
with any MySQL Database Server from
version 3.21 or above, and supports
most of the latest MySQL features
including Trigger, Stored Procedure,
Function, Event, View, and Manage
User, etc.
Features in Navicat are sophisticated
enough to provide professional
developers for all their specific
needs, yet easy to learn for users who
are new to MySQL.
With Navicat well-designed Graphical
User Interface (GUI), Navicat for
MySQL lets you quickly and easily
create, organize, access and share
information in a secure and easy way,
taking MySQL administration.
Sorry, I could only post two links due to not having enough rep at the moment. Maybe someone can edit this and link MySQL Workbench and Navicat.
Hope this helps!
