phpMyAdmin 3.4.8 Documentation * Top * Requirements * Introduction * Installation * Setup script * Configuration * Transformations * FAQ * Developers * Copyright * Credits * Glossary * phpMyAdmin homepage * SourceForge phpMyAdmin project page * Official phpMyAdmin wiki * Local documents: + Version history: ChangeLog + License: LICENSE Requirements * PHP + You need PHP 5.2.0 or newer, with session support (see FAQ 1.31) , the Standard PHP Library (SPL) extension and JSON support. + To support uploading of ZIP files, you need the PHP zip extension. + For proper support of multibyte strings (eg. UTF-8, which is currently the default), you should install the mbstring and ctype extensions. + You need GD2 support in PHP to display inline thumbnails of JPEGs ("image/jpeg: inline") with their original aspect ratio + When using the "cookie" authentication method, the mcrypt extension is strongly suggested for most users and is required for 64?bit machines. Not using mcrypt will cause phpMyAdmin to load pages significantly slower. + To support upload progress bars, see FAQ 2.9. + To support BLOB streaming, see PHP and MySQL requirements in FAQ 6.25. + To support XML and Open Document Spreadsheet importing, you need PHP 5.2.17 or newer and the libxml extension. * MySQL 5.0 or newer (details); * Web browser with cookies enabled. Introduction phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as 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: * browse and drop databases, tables, views, columns and indexes * create, copy, drop, rename and alter databases, tables, columns and indexes * maintenance server, databases and tables, with proposals on server configuration * execute, edit and bookmark any SQL-statement, even batch-queries * load text files into tables * create^1 and read dumps of tables * export^1 data to various formats: CSV, XML, PDF, ISO/IEC 26300 - OpenDocument Text and Spreadsheet, Word, and L^AT[E]X formats * import data and MySQL structures from OpenDocument spreadsheets, as well as XML, CSV, and SQL files * administer multiple servers * manage MySQL users and privileges * check referential integrity in MyISAM tables * using Query-by-example (QBE), create complex queries automatically connecting required tables * create PDF graphics of your Database layout * search globally in a database or a subset of it * transform stored data into any format using a set of predefined functions, like displaying BLOB-data as image or download-link * track changes on databases, tables and views * support InnoDB tables and foreign keys (see FAQ 3.6) * support mysqli, the improved MySQL extension (see FAQ 1.17) * communicate in 62 different languages * synchronize two databases residing on the same as well as remote servers (see FAQ 9.1) A word about users: Many people have difficulty understanding the concept of user management with regards to phpMyAdmin. When a user logs in to phpMyAdmin, that username and password are passed directly to MySQL. phpMyAdmin does no account management on its own (other than allowing one to manipulate the MySQL user account information); all users must be valid MySQL users. ^1) phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats) dumps and CSV exports if you use PHP with Zlib support (--with-zlib) and/or Bzip2 support (--with-bz2). Proper support may also need changes in php.ini. Installation 1. Quick Install 2. Setup script usage 3. phpMyAdmin configuration storage 4. Upgrading from an older version 5. Using authentication modes phpMyAdmin does not apply any special security methods to the MySQL database server. It is still the system administrator's job to grant permissions on the MySQL databases properly. phpMyAdmin's "Privileges" page can be used for this. Warning for Mac users: if you are on a Mac OS version before OS X, StuffIt unstuffs with Mac formats. So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts before uploading them to your server, as PHP seems not to like Mac-style end of lines character ("\r"). Quick Install 1. Choose an appropriate distribution kit from the phpmyadmin.net Downloads page. Some kits contain only the English messages, others contain all languages in UTF-8 format (this should be fine in most situations), others contain all languages and all character sets. We'll assume you chose a kit whose name looks like phpMyAdmin-x.x.x-all-languages.tar.gz. 2. Untar or unzip the distribution (be sure to unzip the subdirectories): tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz in your webserver's document root. If you don't have direct access to your document root, put the files in a directory on your local machine, and, after step 4, transfer the directory on your web server using, for example, ftp. 3. Ensure that all the scripts have the appropriate owner (if PHP is running in safe mode, having some scripts with an owner different from the owner of other scripts will be a problem). See FAQ 4.2 and FAQ 1.26 for suggestions. 4. Now you must configure your installation. There are two methods that can be used. Traditionally, users have hand-edited a copy of config.inc.php, but now a wizard-style setup script is provided for those who prefer a graphical installation. Creating a config.inc.php is still a quick way to get started and needed for some advanced features. + To manually create the file, simply use your text editor to create the file config.inc.php (you can copy config.sample.inc.php to get minimal configuration file) in the main (top-level) phpMyAdmin directory (the one that contains index.php). phpMyAdmin first loads libraries/ config.default.php and then overrides those values with anything found in config.inc.php. If the default value is okay for a particular setting, there is no need to include it in config.inc.php. You'll need a few directives to get going, a simple configuration may look like this: <?php $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice $i=0; $i++; $cfg['Servers'][$i]['auth_type'] = 'cookie'; ?> Or, if you prefer to not be prompted every time you log in: <?php $i=0; $i++; $cfg['Servers'][$i]['user'] = 'root'; $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password $cfg['Servers'][$i]['auth_type'] = 'config'; ?> For a full explanation of possible configuration values, see the Configuration Section of this document. + Instead of manually editing config.inc.php, you can use the Setup Script. First you must manually create a folder config in the phpMyAdmin directory. This is a security measure. On a Linux/Unix system you can use the following commands: cd phpMyAdmin mkdir config # create directory for saving chmod o+rw config # give it world writable permissions And to edit an existing configuration, copy it over first: cp config.inc.php config/ # copy current configuration for editing chmod o+w config/config.inc.php # give it world writable permissions On other platforms, simply create the folder and ensure that your web server has read and write access to it. FAQ 1.26 can help with this. Next, open setup/ in your browser. Note that changes
