Detailed Instructions wordpress installation:
Step 1: Download and Extract
If you have shell access to your web server, and are comfortable using console-based tools, you may wish to download WordPress directly to your web server using wget (or lynx or another console-based web browser) if you want to avoid FTPing:
a) wget http://wordpress.org/latest.tar.gz
b) Then unzip the package using:
tar -xzvf latest.tar.gz
(The WordPress package will extract into a folder called wordpress in the same directory that you downloaded latest.tar.gz.)
Step 2: Create the Database and a User
Create a database for WordPress on your web server, as well as a MySQL user who has all privileges for accessing and modifying it.
step 3 : Rename the wp-config-sample.php file to wp-config.php
mv wp-config-sample.php wp-config.php
step 4 : Open wp-config.php in your favorite text editor and fill in your database details as explained in Editing wp-config.php
Open the renamed wp-config.php file in your favorite text editor and fill in the following information.
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. See some possible DB_HOST values).
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.
step 5. 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. http://example.com/), 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. http://example.com/blog/), rename the directory wordpress 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.
(Hint: If your FTP transfer is too slow read how to avoid FTPing at : Step 1: Download and Extract. )
step 6. Run the WordPress installation script by accessing wp-admin/install.php in your favorite web browser.
* If you installed WordPress in the root directory, you should visit: http://example.com/wp-admin/install.php
* If you installed WordPress in its own subdirectory called blog, for example, you should visit: http://example.com/blog/wp-admin/install.php
That's it! WordPress should now be installed.
