== Things to Know Before You Begin==
+
Before you begin the install, there are few things you need to have and do.
+
 
+
=== Things You Need For The Installation ===
+
 
+
You need access to your site and its directory and software to proceed with the installation. These are:
+
 
+
* Access to your [[Glossary#Web server|web server]] (via [[Glossary#Shell|shell]] or [[Glossary#FTP|FTP]])
+
* A [[Glossary#Text editor|text editor]]
+
* An [[FTP_Clients|FTP Client]] (if you need to install WordPress on a remote server)
+
* Your web browser of choice
+
 
+
===Things You Need to Do For The Installation===
+
 
+
Begin your installation by:
+
 
+
# Checking to ensure that you and your web host has the [http://wordpress.org/about/requirements/ minimum requirements to run WordPress].
+
# [http://wordpress.org/download/ Download] the latest release of WordPress.
+
# Unzip the downloaded file to a folder on your hard drive.
+
# Print this page out so you have it handy during the installation.
+
 
+
== Famous 5-Minute Install ==
+
 
+
Here's the quick version of the instructions, for those that are already comfortable with performing such installations. More [[#Detailed_Instructions|detailed instructions]] follow.
+
 
+
# Download and unzip the WordPress package, if you haven't already.
+
# Create a database for WordPress on your web server, as well as a [[Glossary#MySQL|MySQL]] user who has all privileges for accessing and modifying it.
+
# Rename the <tt>wp-config-sample.php</tt> file to <tt>wp-config.php</tt>.
+
# Open <tt>wp-config.php</tt> in your favorite [[Glossary#Text editor|text editor]] and [[#Step_3:_Set_up_wp-config.php|fill in your database details]].
+
# Place the WordPress files in the desired location on your web server:
+
#* If you want to integrate WordPress into the root of your domain (e.g. <tt><nowiki>http://example.com/</nowiki></tt>), move or upload all contents of the unzipped WordPress directory (but excluding the directory itself) into the root directory of your web server.
+
#* If you want to have your WordPress installation in its own subdirectory on your web site (e.g. <tt><nowiki>http://example.com/blog/</nowiki></tt>), rename the directory <tt>wordpress</tt> to the name you'd like the subdirectory to have and move or upload it to your web server. For example if you want the WordPress installation in a subdirectory called "blog", you should rename the directory called "wordpress" to "blog" and upload it to the root directory of your web server.<br><br>'''Hint''': If your FTP transfer is too slow read how to avoid FTPing at : [http://codex.wordpress.org/Installing_WordPress#Step_1:_Download_and_Extract Step 1: Download and Extract].
+
# Run the WordPress installation script by accessing <tt>wp-admin/install.php</tt> in your favorite web browser.
+
#* If you installed WordPress in the root directory, you should visit: <tt><nowiki>http://example.com/wp-admin/install.php</nowiki></tt>
+
#* If you installed WordPress in its own subdirectory called <tt>blog</tt>, for example, you should visit: <tt><nowiki>http://example.com/blog/wp-admin/install.php</nowiki></tt>
+
 
+
That's it! WordPress should now be installed.

+
== Detailed Instructions ==
+
 
+
=== Step 1: Download and Extract ===
+
 
+
Download and unzip the WordPress package from http://wordpress.org/download/.
+
* If you will be uploading WordPress to a remote web server, download the WordPress package to your computer with your favorite web browser and unzip the package.
+
* If you have [[Glossary#Shell|shell]] access to your web server, and are comfortable using console-based tools, you may wish to download WordPress directly to your [[Glossary#Web server|web server]] using <tt>wget</tt> (or <tt>lynx</tt> or another console-based web browser) if you want to avoid [[Glossary#FTP|FTPing]]:
+
** <tt>wget <nowiki>http://wordpress.org/latest.tar.gz</nowiki></tt>
+
** Then unzip the package using: <br /> <tt>tar -xzvf latest.tar.gz </tt> <br><br>The WordPress package will extract into a folder called <tt>wordpress</tt> in the same directory that you downloaded <tt>latest.tar.gz</tt>.
+
 
+
* If you do '''not''' have [[Glossary#Shell|shell]] access to your web server, or you are not comfortable using console-based tools, you may wish to deploy WordPress directly to your [[Glossary#Web server|web server]] using [http://ftp-unzip.com/ZipDeploy/ ZipDeploy].
+
 
+
=== Step 2: Create the Database and a User ===
+
 
+
If you are using a [[Glossary#Hosting provider|hosting provider]], you may already have a WordPress database set up for you, or there may be an automated setup solution to do so. Check your hosting provider's support pages or your [[Using cPanel|control panel]] for clues about whether or not you'll need to create one manually.
+
 
+
If you determine that you'll need to create one manually, follow the instructions for [[WordPress_Backups#Accessing_phpMyAdmin|accessing phpMyAdmin on various servers]], or follow the instructions for [[#Using_cPanel|'''Using cPanel''']] or [[#Using phpMyAdmin|'''Using phpMyAdmin''']] below.
+
 
+
If you are installing WordPress on your own web server, follow the [[#Using phpMyAdmin|'''Using phpMyAdmin''']] or [[#Using the MySQL Client|'''Using the MySQL Client''']] instructions below to create your WordPress username and database.
+
 
+
==== Using cPanel ====
+
 
+
''Main article: [[Using cPanel]]''
+
 
+
If your hosting provider uses [[Glossary#cPanel|cPanel]], you may follow these instructions to create your WordPress username and database.
+
 
+
# Log in to your [[Glossary#cPanel|cPanel]].
+
# Click '''MySQL Databases'''.
+
# If a user relating to WordPress does not already exist under the '''Users''' section, create one:
+
## Chose a username for WordPress ('<tt>wordpress</tt>' is good) and enter it in the '''UserName''' field.
+
## Choose a difficult-to-guess password (ideally containing a combination of upper- and lower-case letters, numbers, and symbols), and enter it in the '''Password''' field.
+
## Write down the username and password you chose.
+
## Click '''Add User'''.
+
# If a database relating to WordPress does not already exist under the '''Databases''' section, create one:
+
## Choose a name for your WordPress database ('<tt>wordpress</tt>' or '<tt>blog</tt>' are good), enter it in the '''Db''' field, and click '''Add Db'''.
+
# Under '''Databases''', select your WordPress username from the '''User''' dropdown, then select your WordPress database from the '''Db''' dropdown. Make sure '''All''' is checked under '''Privileges''', then click '''Add User to Db'''.
+
# When you return to the main '''MySQL Account Maintenance''' screen, [[Glossary#cPanel|cPanel]] will list information about the database you just created. You should see the username you just added to the database (with <tt>ALL PRIVILEGES</tt>), as well as a few sample '''Connection Strings''' for you to use in [[Glossary#Perl|Perl]] or [[Glossary#PHP|PHP]] scripts to connect to the database. The PHP code will have the following format:
+
$dbh = mysql_connect("''hostname''", "''username''", "<PASSWORD HERE>") or die ("''message''");
+
mysql_select_db("''databasename''");
+
: Write down the values of ''hostname'', ''username'', ''databasename'', and the password you chose. (Note that ''hostname'' will usually be '''localhost'''.)
+
 
+
==== Using phpMyAdmin ====
+
 
+
If your web server has [[Glossary#phpMyAdmin|phpMyAdmin]] installed, you may follow these instructions to create your WordPress username and database.
+
 
+
'''''Note:''' These instructions are written for phpMyAdmin 2.6.0; the phpMyAdmin user interface can vary slightly between versions.''
+
 
+
# If a database relating to WordPress does not already exist in the '''Database''' dropdown on the left, create one:
+
## Choose a name for your WordPress database ('<tt>wordpress</tt>' or '<tt>blog</tt>' are good), enter it in the '''Create new database''' field, and click '''Create'''.
+
# Click the '''Home''' icon in the upper left to return to the main page, then click '''Privileges'''. If a user relating to WordPress does not already exist in the list of users, create one:
+
## Click '''Add a new User'''.
+
## Chose a username for WordPress ('<tt>wordpress</tt>' is good) and enter it in the '''User name''' field. (Be sure '''Use text field:''' is selected from the dropdown.)
+
## Choose a difficult-to-guess password (ideally containing a combination of upper- and lower-case letters, numbers, and symbols), and enter it in the '''Password''' field. (Be sure '''Use text field:''' is selected from the dropdown.) Re-enter the password in the '''Re-type''' field.
+
## Write down the username and password you chose.
+
## Leave all options under '''Global privileges''' at their defaults.
+
## Click '''Go'''.
+
# Return to the '''Privileges''' screen and click the '''Check privileges''' icon on the user you've just created for WordPress. In the '''Database-specific privileges''' section, select the database you've just created for WordPress under the '''Add privileges to the following database''' dropdown. The page will refresh with privileges for that database. Click '''Check All''' to select all privileges, and click '''Go'''.
+
# On the resulting page, make note of the host name listed after '''Server:''' at the top of the page. (This will usually be '''localhost'''.)
+
 
+
==== Using the MySQL Client ====
+
 
+
If you have [[Glossary#Shell|shell]] access to your web server, are comfortable with using the command line, and your MySQL user has the [[Glossary#Permissions|permissions]] to create MySQL users and databases, you may follow the example session below to create your WordPress username and database.
+
<pre>
+
$ mysql -u adminusername -p
+
Enter password:
+
Welcome to the MySQL monitor.  Commands end with ; or \g.
+
Your MySQL connection id is 5340 to server version: 3.23.54
+
+
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
+
+
mysql> CREATE DATABASE databasename;
+
Query OK, 1 row affected (0.00 sec)
+
+
mysql> GRANT ALL PRIVILEGES ON databasename.* TO "wordpressusername"@"hostname"
+
    -> IDENTIFIED BY "password";
+
Query OK, 0 rows affected (0.00 sec)
+
 
+
mysql> FLUSH PRIVILEGES;
+
Query OK, 0 rows affected (0.01 sec)
+
 
+
mysql> EXIT
+
Bye
+
$
+
</pre>
+
In the above:
+
* ''adminusername'' will typically be <tt>root</tt>, unless you have another high-privileged account set up.
+
* <tt>wordpress</tt> or <tt>blog</tt> are good values for ''databasename''.
+
* <tt>wordpress</tt> is a good value for ''wordpressusername''.
+
* ''hostname'' will usually be <tt>localhost</tt>. If you don't know what this value should be, check with your system administrator. If you are the system administrator, figure out what this value should be.
+
* ''password'' should be a difficult-to-guess password, ideally containing a combination of upper- and lower-case letters, numbers, and symbols.
+
 
+
Write down the values you used for ''databasename'', ''wordpressusername'', ''hostname'', and ''password''.
+
 
+
==== Using Plesk ====
+
See:
+
*[http://www.tamba2.org.uk/wordpress/plesk/ Plesk 7 at tamba2.org]
+
 
+
=== Step 3: Set up wp-config.php ===
+
 
+
For the next part, the code you will be looking to change is as follows:
+
 
+
<pre>// ** MySQL settings ** //
+
define('DB_NAME', 'wordpress');    // The name of the database
+
define('DB_USER', 'username');    // Your MySQL username
+
define('DB_PASSWORD', 'password'); // ...and password
+
define('DB_HOST', 'localhost');    // 99% chance you won't need to change this value
+
define('DB_CHARSET', 'utf8');
+
define('DB_COLLATE', '');</pre>
+
 
+
# Returning to where you extracted the WordPress package in '''Step 1''', rename the file <tt>wp-config-sample.php</tt> to <tt>wp-config.php</tt>.
+
# Open the renamed <tt>wp-config.php</tt> file in your favorite [[Glossary#Text editor|text editor]] and fill in the following information, per the example above:
+
#; '''DB_NAME''' : The name of the database you created for WordPress in '''Step 2''' .
+
#; '''DB_USER''' : The username you created for WordPress in '''Step 2'''.
+
#; '''DB_PASSWORD''' : The password you chose for the WordPress username in '''Step 2'''.
+
#; '''DB_HOST''' : The hostname you determined in '''Step 2''' (usually <tt>localhost</tt>, but not always).
+
#; '''DB_CHARSET''' : The database character set, normally should not be changed.  See ''[[Editing wp-config.php]]'' for details.
+
#; '''DB_COLLATE''' : The database collation should normally be left blank.  See ''[[Editing wp-config.php]]'' for details.
+
# Save the file.
+
 
+
For more extensive details, and step by step instruction for creating the configuration file, please refer to ''[[Editing wp-config.php]]''.
+
 
+
=== Step 4: Place the files ===
+
 
+
Now you will need to decide where on your web site you'd like your blog to appear:
+
* In the root directory of your web site. (For example, <tt><nowiki>http://example.com/</nowiki></tt>)
+
* In a subdirectory of your web site. (For example, <tt><nowiki>http://example.com/blog/</nowiki></tt>)
+
 
+
'''''Note:''' The location of your root web directory in the filesystem on your [[Glossary#Web server|web server]] will vary across hosting providers and operating systems. Check with your [[Glossary#Hosting provider|hosting provider]] or system administrator if you do not know where this is.''
+
 
+
==== In the Root Directory ====
+
 
+
* If you need to upload your files to your web server, use your favorite [[Glossary#FTP|FTP]] client to upload all the ''contents'' of the <tt>wordpress</tt> directory (but not the directory itself) into the root directory of your web site.
+
* If your files are already on your web server, and you are using [[Glossary#Shell|shell]] access to install WordPress, move all of the ''contents'' of the <tt>wordpress</tt> directory (but not the directory itself) into the root directory of your web site.
+
 
+
==== In a Subdirectory ====
+
 
+
* If you need to upload your files to your web server, rename the <tt>wordpress</tt> directory to your desired name, then use your favorite [[Glossary#FTP|FTP]] client to upload the directory to your desired location within the root directory of your web site.
+
* If your files are already on your web server, and you are using [[Glossary#Shell|shell]] access to install WordPress, move the <tt>wordpress</tt> directory to your desired location within the root directory of your web site, and rename the directory to your desired name.
+
 
+
=== Step 5: Run the Install Script ===
+
 
+
Using your favorite web browser, visit <tt>wp-admin/install.php</tt> within the directory into which you just installed WordPress on your web site.
+
* If you installed into a subdirectory called <tt>blog</tt>, you would visit <tt><nowiki>http://example.com/blog/wp-admin/install.php</nowiki></tt>.
+
* If you installed into the root directory of your web site, you would visit <tt><nowiki>http://example.com/wp-admin/install.php</nowiki></tt>.
+
 
+
The following screenshots show how the installation progresses.  Notice in the second screen, Entering the details, you enter your Weblog title and your e-mail address.  Also displayed is a check-box asking if you would like your blog to appear in search engines like Google and Technorati.  Leave the box checked if you would like your blog to be visible to everyone, including search engines, and uncheck the box if you want to block search engines, but allow normal visitors.  Note all this information can be changed later in your [[Administration_Panels|Administration Panels]].
+
 
+
<div>
+

[[Image:install-step3.png|left|thumb|All done!]] -->
+
</div>
+
<div style="clear:both;height:10px">
+
</div>
+
 
+
==== Install Script Troubleshooting ====
+
 
+
* If you get an error about the database when you run the install script:
+
** Go back to [[#Step_2:_Create_the_Database_and_a_User|Step 2]] and [[#Step_3:_Set_up_wp-config.php|Step 3]], and be sure you got all the correct database information and that it was entered correctly into <tt>wp-config.php</tt>.
+
** Be sure you granted your WordPress user permission to access your WordPress database in '''Step 3'''.
+
** Be sure the database server is running.
+
 
+
== Common Installation Problems ==
+
 
+
The following are some of the most common installation problems.  For more information and troubleshooting for problems with your WordPress installation, check out [[FAQ Installation]] and [[FAQ Troubleshooting]].
+
 
+
; I see lots of <tt>Headers already sent</tt> errors. How do I fix this? : You probably introduced a syntax error in editing <tt>wp-config.php</tt>.
+
:# Download <tt>wp-config.php</tt> (if you don't have [[Glossary#Shell|shell]] access).
+
:# Open it in your favorite [[Glossary#Text editor|text editor]].
+
:# Check that the first line contains nothing but <tt><?php</tt>, and that there is '''no''' text before it (not even whitespace).
+
:# Check that the last line contains nothing but <tt>?></tt>, and that there is '''no''' text after it (not even whitespace).
+
:# Save the file, upload it again if necessary, and reload the page in your browser.
+
 
+
; My page comes out gibberish. When I look at the source I see a lot of "<tt><?php ?></tt>" tags. : If the <tt><?php ?></tt> tags are being sent to the browser, it means your [[Glossary#PHP|PHP]] is not working properly. All PHP code is supposed to be executed ''before'' the server sends the resulting [[Glossary#HTML|HTML]] to your web browser. (That's why it's called a ''pre''processor.) Make sure your web server meets the requirements to run WordPress, that PHP is installed and configured properly, or contact your hosting provider or system administrator for assistance.
+
 
+
; I keep getting an <tt>Error connecting to database</tt> message but I'm sure my configuration is correct. : Try resetting your MySQL password manually. If you have access to MySQL via shell, try issuing:
+
 
+
SET PASSWORD FOR '<var>wordpressusername</var>'@'<var>hostname</var>' = OLD_PASSWORD('<var>password</var>');
+
 
+
: If you are using a version of MySQL prior to 4.1, use <tt>PASSWORD</tt> instead of <tt>OLD_PASSWORD</tt>. If you do not have shell access, you should be able to simply enter the above into an SQL query in phpMyAdmin. Failing that, you may need to use your host's control panel to reset the password for your database user.
+
 
+
; My image/MP3 uploads aren't working. : If you use the Rich Text Editor on a blog  that's installed in a subdirectory, and drag a newly uploaded image into  the editor  field, the image may vanish a couple seconds later. This is due to a problem with TinyMCE (the rich text editor) not getting enough information during the drag operation to construct the path to the image or other file  correctly. The solution is to  NOT drag uploaded images into the editor. Instead, click and  hold on the image and select "Send to Editor."
