phpMyAdmin can manage a whole MySQL-server (needs a super-user) but also a single database. To accomplish the latter you'll need a properly set up MySQL-user who can read/write only the desired database. It's up to you to look up the appropriate part in the MySQL manual. Currently phpMyAdmin can:
| (*) | phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats) dumps and CSV exports if you use PHP4 >= 4.0.4 with Zlib support (--with-zlib) and/or Bzip2 support (--with-bz2). |
NOTE: phpMyAdmin does not apply any special security methods to the MySQL database server. It is still the sysadmin's job to grant permissions on the MySQL databases properly.
Warning for Mac users: php seems not to like
Mac end of lines character ("\r") and Stuffit unstuffs
with Mac formats, of course.
So you'll have to resave as in Bbedit to unix style ALL phpMyAdmin scripts
before uploading them to your server.
Documentation warning: when you see in this document a .php3 file extension, please transpose to .php if you are using a kit with files having this extension.
Quick Install:
Upgrading from an older version:
Using authentication modes:
|
GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass'; GRANT SELECT (Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv, Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv, File_priv, Grant_priv, References_priv, Index_priv, Alter_priv) ON mysql.user TO 'pma'@'localhost'; GRANT SELECT ON mysql.db TO 'pma'@'localhost'; GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv) ON mysql.tables_priv TO 'pma'@'localhost'; |
|
| ... and if you want to use the bookmark feature: | |
| GRANT SELECT, INSERT, DELETE ON <bookmark_db>.<bookmark_table> TO 'pma'@'localhost'; | |
'http' authentication mode:
'cookie' authentication mode:
'config' authentication mode:
Warning for Mac users: php seems not to like Mac end of lines character ("\r"). So ensure you choose the option that allows to use the *nix end of line character ("\n") in your text editor before registering a script you have modified.
All configurable data is placed in config.inc.php3.
$cfgPmaAbsoluteUri = (!empty($HTTPS) ? 'https' : 'http') . '://'
. $HTTP_HOST . (!empty($SERVER_PORT) ? ':' . $SERVER_PORT : '')
. substr($PHP_SELF, 0, strrpos($PHP_SELF, '/')+1);
or
$cfgPmaAbsoluteUri = (!empty($HTTPS) ? 'https' : 'http') . '://'
. $SERVER_NAME . (!empty($SERVER_PORT) ? ':' . $SERVER_PORT : '')
. substr($SCRIPT_NAME, 0, strrpos($SCRIPT_NAME, '/')+1);
I'm running php 4+ and my server is crashing each time a specific action
is required or phpMyAdmin sends a blank page or a page full of cryptic
characters to my browser, what can I do?
There are some known php bugs with output buffering and compression.
Try to set the $cfgOBGzip directive to FALSE in your
config.inc.php or .php3 file and the
zlib.output_compression directive to Off in your php
configuration file.
Furthermore, we know about such problems connected to php 4.2.0 (tested
with php 4.2.0 RC1 to RC4) together with MS Internet Explorer.
Unfortunatly, the only solution for this bug seems to be switching back to
an earlier php version.
My Apache server crashes when using phpMyAdmin.
You should first try the latest versions of Apache (and possibly MySQL).
See also the other FAQ entry about php bugs with output buffering.
If your server keeps crashing, please ask for help in the various
Apache support groups.
Using phpMyAdmin on IIS, I'm displayed the error message: "The
specified CGI application misbehaved by not returning a complete set of
HTTP headers...."
You just forgot to read the install.txt file from the php
distribution. Have a look at the last message in this
bug report from the
official php bug database.
Using phpMyAdmin on IIS, I'm facing crashes and/or many error messages
with the http or advanced authentication mode.
This is a known problem with the php ISAPI filter: it's not so stable. For
some more information and complete testings see the messages posted by
André B. aka "djdeluxe76" in
this thread
from the phpWizard forum.
Please use instead the cookie authentication mode.
I can't use phpMyAdmin on PWS: nothing is displayed!
This seems to be a PWS bug. Filippo Simoncini found a workaroud (at this
time there is no better fix): remove or comment the DOCTYPE
declarations (3 lines) from the scripts header.inc.php3,
index.php3, left.php3 and libraries/common.lib.php3.
How can I GZip or Bzip a dump or a CSV export. It seems to not work?
These features are based on the gzencode() and
bzcompress() php functions to be more independent of the platform
(Unix/Windows, Safe Mode or not, and so on).
So, you must have PHP4 >= 4.0.4 and Zlib/Bzip2 support
(--with-zlib and --with-bz2).
We faced php crashes when trying to download a dump with MS Internet
Explorer when phpMyAdmin is run with php 4.2.0 (tested with php 4.2.0 RC1
to RC4). In this case you should switch back to an earlier php version.
I cannot insert a text file in a table, and I get an error about safe
mode being in effect.
Your uploaded file is saved by PHP in the "upload dir", as
defined in php.ini by the variable upload_tmp_dir (usually
the system default is /tmp).
We recommend the following setup for Apache servers running in safe mode,
to enable uploads of files while being reasonably secure:
I'm having troubles when uploading files. In general file uploads don't
work on my system and uploaded files have a Content-Type: header
in the first line.
It's not really phpMyAdmin related but RedHat 7.0. You have a RedHat 7.0
and you updated your php rpm to php-4.0.4pl1-3.i386.rpm, didn't you?
So the problem is that this package has a serious bug that was corrected
ages ago in php (2001-01-28: see
php's bug tracking system
for more details). The problem is that the bugged package is still
available though it was corrected (see
redhat's bugzilla
for more details).
So please download
the fixed package (4.0.4pl1-9)
and the problem should go away.
And that fixes the \r\n problem with file uploads!
I'm having troubles when uploading files with phpMyAdmin running on a
secure server. My browser is Internet Explorer and I'm using the Apache
server.
As suggested by "Rob M" in the phpWizard forum, add this line to
your httpd.conf:
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
It seems to clear up many problems between IE and SSL.
I get an 'open_basedir restriction' while uploading a file from the
query box.
Since version 2.2.4, phpMyAdmin supports servers with open_basedir
restrictions. Assuming that the restriction allows you to open files in the
current directory ('.'), all you have to do is create a 'tmp' directory
under the phpMyAdmin install directory, with permissions 777 and the same
owner as the owner of your phpMyAdmin directory. The uploaded files will
be moved there, and after execution of your SQL commands, removed.
I have lost my MySQL root password, what can I do?
The MySql manual explains how to
reset the permissions.
I get an error 'No SQL query' when trying to execute a bookmark.
If PHP does not have read/write access to its upload_tmp_dir, it
cannot access the uploaded query.
I get an error 'No SQL query' when trying to submit a query from the
convenient text area.
Check the post_max_size directive from your php configuration file
and try to increase it.
I have problems with mysql.user field names.
In older MySQL versions, the User and Password fields
were named user and password. Please modify your field
names to align with current standards.
I cannot upload big dump files.
The first things to check (or ask your host provider to check) are the
values of upload_max_filesize, memory_limit and
post_max_size in the php.ini configuration file.
All of these three settings limit the maximum size of data that can be
submitted and handled by php.
Does phpMyAdmin support MySQL 4?
MySQL 4 is not yet fully supported by phpMyAdmin.
Because of MySQL 4's backwards compatibility you can use phpMyAdmin
for administering MySQL 4 servers, but phpMyAdmin does not yet
support its new features. Please notice that in this case it is recommended
to use php >= 4.1 since older versions of php are not
compatible to MySQL 4.
Furthermore, several users reported problems with phpMyAdmin related to
bugs in MySQL 4. MySQL 4 is still an alpha
release and should be used for test purposes only!
I'm running MySQL 4.0.1 on a Windows NT machine. Each time I
create a table the table name is changed to lowercase.
This seems to be a bug of MySQL 4.0.1 because it also appears when
using the MySQL commandline. Currently we only know about its appearance on
Windows NT systems, but it is possible that it appears on other
systems, too.
If you encounter this bug together with another OS and/or MySQL version or
you know how to work around it, please post a message into
our bug tracker at SourceForge.
The error message "Warning: Cannot add header information - headers
already sent by ..." is displayed, what's the problem?
Edit your config.inc.php or .php3 file and ensure there is nothing
(ie no blank lines, no spaces, no characters...) neither before the
<?php tag at the beginning, neither after the ?>
tag at the end.
phpMyAdmin can't connect to MySQL. What's wrong?
Either there is an error with your PHP setup or your username/password is
wrong. Try to make a small script which uses mysql_connect and see if it
works. If it doesn't, it may be you haven't even compiled MySQL support
into PHP.
The error message "Warning: MySQL Connection Failed: Can't connect
to local MySQL server through socket '/tmp/mysql.sock' (111)...") is
displayed. What can I do?
For RedHat users, Harald Legner suggests this on the mailing list:
On my RedHat-Box the socket of mysql is /var/lib/mysql/mysql.sock.
In your php.ini you will find a line
mysql.default_socket = /tmp/mysql.sock
change it to
mysql.default_socket = /var/lib/mysql/mysql.sock
Then restart apache and it will work.
Here is a fix suggested by Brad Ummer in the
phpwizard forum:
Have also a look at the corresponding section of the MySQL documentation.
Nothing is displayed by my browser when I try to run phpMyAdmin, what
can I do?
Try to set the $cfgOBGZip directive to FALSE in the
phpMyAdmin configuration file. It helps sometime.
Also have a look at your php version number: if it contains
"4.0b..." it means you're running a beta version of PHP. That's
not a so good idea, please upgrade to a plain revision.
Each time I want to insert or change a record or drop a database or a
table, an error 404 (page not found) is displayed or, with http or
cookie authentication, I'm asked to login again. What's wrong?
Check the value you set for the $cfgPmaAbsoluteUri directive in
the phpMyAdmin configuration file.
When using http authentication, an user who logged out can not relog
in with the same nick.
This is related to the authentication mechanism (protocol) used by
phpMyAdmin. We plan to change it as soon as we may find enough free time
to do it, but you can bypass this problem: just close all the opened
browser windows and then go back to phpMyAdmin. You should be able to
logs in again.
When dumping a large table in compressed mode, I get a memory limit
error or a time limit error.
As of version 2.2.4, we build the compressed dump in memory, so large
tables dumps may hang. The only alternative we can think about (using
system calls to mysqldump then gzip or bzip2) would not be applicable in
environments where PHP is in safe mode: access to system programs is
is limited by the system administrator, and time limit is enforced.
I'm an ISP. Can I setup one central copy of phpMyAdmin or do I need to
install it for each customer?
Since version 2.0.3, you can setup a central copy of phpMyAdmin for all
your users. The development of this feature was kindly sponsored by
NetCologne GmbH.
This requires a properly setup MySQL user management and phpMyAdmin
http authentication. See the install section on
"Using http authentication".
What's the preferred way of making phpMyAdmin secure against evil
access?
This depends on your system.
If you're running a server which cannot be accessed by other people, it's
sufficient to use the directory protection bundled with your webserver
(with Apache you can use .htaccess files, for example).
If other people have telnet access to your server, you should use
phpMyAdmin's http authentication feature.
Suggestions:
I get errors about not being able to include a file in /lang
or in /libraries.
Check php.ini, or ask your sysadmin to check it. The
include_path must contain "." somewhere in it, and
open_basedir, if used, must contain "." and
"./lang" to allow normal operation of phpMyAdmin.
phpMyAdmin always gives "Access denied" when using http
authentication.
This could happen for several reasons:
Is it possible to let users create their own databases?
Starting with 2.2.5, in the user management page, you can enter a wildcard
database name for a user, and put the privileges you want. For example,
adding SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER
would let a user create/manage his/her database(s).
I get an out of memory error, and my controls are non-functional, when
trying to create a table with more than 14 fields.
We could reproduce this problem only under Win98/98SE. Testing under
WinNT4 or Win2K, we could easily create more than 60 fields.
A workaround is to create a smaller number of fields, then come back to
your table properties and add the other fields.
With Xitami 2.5b4, phpMyAdmin won't process form fields.
This is not a phpMyAdmin problem but a Xitami known bug: you'll face it
with each script/website that use forms.
Upgrade or downgrade your Xitami server.
I have problems dumping tables with Konqueror (phpMyAdmin 2.2.2)
With Konqueror 2.1.1: plain dumps, zip and gzip dumps work ok, except that
the proposed file name for the dump is always 'tbl_dump.php'. Bzip2 dumps
don't seem to work.
With Konqueror 2.2.1: plain dumps work; zip dumps are placed into
the user's temporary directory, so they must be moved before closing
Konqueror, or else they disappear. Gzip dumps give an error message.
Testing needs to be done for Konqueror 2.2.2.
I can't use the cookie authentication mode because Internet Explorer
never stores the cookies.
MS Internet Explorer seems to be really buggy about cookies, at least till
version 6. And thanks to Andrew Zivolup we've traced also a php 4.1.1 bug
in this area!
Then, If you're running php 4.1.1, try to upgrade or downgrade... it may
works!
In Internet Explorer 5.0, I get Javascript errors when browsing my
rows.
Upgrade to at least Internet Explorer 5.5SP2.
In Internet Explorer 5.0, 5.5 or 6.0, I get an error when trying to
modify a row in a table with many fields, or with a text field.
Your table neither have a primary key nor an unique one, so we must use a
long URL to identify this row. There is a limit on the lenght of the URL in
those browsers, and this not happen in Netscape, for example. The
workaround is to create a primary or unique key, or use another browser.
I refresh (reload) my browser, and come back to the welcome page.
Some browsers support right-clicking into the frame you want to refresh,
just do this in the right frame.
With Mozilla 0.9.7 I have problems sending a query modified in the query
box.
Looks like a Mozilla bug: 0.9.6 was ok. We will keep an eye on future
Mozilla versions.
I can't insert new rows into a table - MySQL brings up a SQL-error.
Examine the SQL error with care. I've found that many programmers
specifying a wrong field-type.
Common errors include:
Also, look at the syntax chapter in the MySQL manual to confirm that your syntax is correct.
When I create a table, I click the Index checkbox for 2 fields and
phpMyAdmin generates only one index with those 2 fields.
In phpMyAdmin 2.2.0 and 2.2.1, this is the way to create a multi-fields
index. If you want two indexes, create the first one when creating the
table, save, then display the table properties and click the Index link to
create the other index.
How can I insert a null value into my table?
Since version 2.2.3, you have a checkbox for each field that can be null.
Before 2.2.3, you had to enter "null", without the quotes, as the
field's value.
How can I backup my database or table?
Click on a database or table name in the left frame, the properties will be
displayed. Then go to the Dump section, you can dump the structure, the
data, or both. This will generate standard SQL statements that can be used
to recreate your database/table.
You will need to choose "Save as file", so that phpMyAdmin can
transmit the resulting dump to your station. Depending on your PHP
configuration, you will see options to compress the dump. See also the
$cfgExecTimeLimit configuration variable.
For additional help on this subject, look for the word "dump" in
this document.
How can I restore (upload) my database or table using a dump?
Click on a database name in the left frame, the properties will be
displayed. Then in the "Run SQL query" section, type in your local
dump filename, or use the Browse button. Then click Go.
For additional help on this subject, look for the word "upload" in
this document.
I have found a bug. How do I inform developers?
Our Bug Tracker is located at
http://sourceforge.net/projects/phpmyadmin/ under the Bugs section.
But please first discuss your bug with other users:
http://sourceforge.net/projects/phpmyadmin/ (and choose Forums)
I want to translate the messages to a new language or upgrade an
existing language, where do I start?
Always use the current cvs version of your language file.
For a new language, start from english.inc.php3. If you don't know how to
get the cvs version, please ask one of the developers.
You can then put your translations, as a zip file to avoid losing special
characters, on the sourceforge.net translation tracker.
It would be a good idea to subscribe to the phpmyadmin-translators mailing
list, because this is where we ask for translations of new messages.
I would like to help out with the development of phpMyAdmin. How should
I proceed?
The following method is preferred for new developers:
Write access to the CVS tree is granted only to experienced developers who
have already contributed something useful to phpMyAdmin.
Also, have a look at the Developers section.
phpMyAdmin is Open Source, so you're invited to contribute to it. Many great features have been written by other people and you too can help to make phpMyAdmin a useful tool.
If you're planning to contribute source, please read the following information:
IMPORTANT: With 1.4.1, development has switched to CVS. The following method is preferred for new developers:
Write access to the CVS tree is granted only to developers who have already contributed something useful to phpMyAdmin. If you're interested in that, please contact us using the phpmyadmin-devel mailing list.

Original Credits of Version 2.1.0
---------------------------------
This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
to create a web-based interface to MySQL using PHP3. Although I have not
used any of his source-code, there are some concepts I've borrowed from
him. phpMyAdmin was created because Peter told me he wasn't going to
further develop his (great) tool.
Thanks go to
- Amalesh Kempf <ak-lsml_at_living-source.com> who contributed the
code for the check when dropping a table or database. He also suggested
that you should be able to specify the primary key on tbl_create.php3. To
version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
well as a bug-report. Plus many smaller improvements.
- Jan Legenhausen <jan_at_nrw.net>: He made many of the changes that
were introduced in 1.3.0 (including quite significant ones like the
authentication). For 1.4.1 he enhanced the table-dump feature. Plus
bug-fixes and help.
- Marc Delisle <DelislMa_at_CollegeSherbrooke.qc.ca> made phpMyAdmin
language-independent by outsourcing the strings to a separate file. He
also contributed the French translation.
- Alexandr Bravo <abravo_at_hq.admiral.ru> who contributed
tbl_select.php3, a feature to display only some fields from a table.
- Chris Jackson <chrisj_at_ctel.net> added support for MySQL
functions in tbl_change.php3. He also added the
"Query by Example" feature in 2.0.
- Dave Walton <walton_at_nordicdms.com> added support for multiple
servers and is a regular contributor for bug-fixes.
- Gabriel Ash <ga244_at_is8.nyu.edu> contributed the random access
features for 2.0.6.
