If you are using a 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 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 accessing phpMyAdmin on various servers, or follow the instructions for Using cPanel or Using phpMyAdmin below.

Step 3: Set up wp-config.php

For the next part, the code you will be looking to change is as follows:

// ** 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

1. Returning to where you extracted the WordPress package in Step 1, rename the file wp-config-sample.php to wp-config.php.
2. Open the renamed wp-config.php file in your favorite 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 localhost, but not always).

3. Save the file.

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, http://example.com/)

In the Root Directory

• If you need to upload your files to your web server, use your favorite FTP client to upload all the contents of the wordpress directory (but not the directory itself) into the root directory of your web site.

Step 5: Run the Install Script

Using your favorite web browser, visit wp-admin/install.php within the directory into which you just installed WordPress on your web site.

Installing WordPress Locally

If you have a sufficiently powerful home computer and a sufficiently fast broadband connection, you may want to avoid certain hosting charges by using your own computer as a server. The following tutorials will show you how to setup a server environment and install WordPress on your home computer.

Using phpMyAdmin

If your web server has 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.

1. If a database relating to WordPress does not already exist in the Database dropdown on the left, create one:
   1. Choose a name for your WordPress database ('wordpress' or 'blog' are good), enter it in the Create new database field, and click Create.
2. 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:
   1. Click Add a new User.
   2. Chose a username for WordPress ('wordpress' is good) and enter it in the User name field. (Be sure Use text field: is selected from the dropdown.)
   3. 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.
   4. Write down the username and password you chose.
   5. Leave all options under Global privileges at their defaults.
   6. Click Go.
3. 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.
4. 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 shell access to your web server, are comfortable with using the command line, and your MySQL user has the permissions to create MySQL users and databases, you may follow the example session below to create your WordPress username and database.

$ 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
$ 

In the above:

• adminusername will typically be root, unless you have another high-privileged account set up.
• wordpress or blog are good values for databasename.
• wordpress is a good value for wordpressusername.
• hostname will usually be localhost. 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.
