I think now you know how to install WordPress in default language(English) after reading the articles above.Whatever now i will show you how to change the default(English) language in WordPress into Bengali.

Step2:Download required language file
WordPress usually use English as it’s standard ,if we want to change the language anything else we need a file with .mo extension.So we need this file for installing WordPress in Bengali.So start by downloading this file from Here.In this link you will find two file one is bn_BD.mo and the another is bn_BD.po.You can download both of the file but we will need only one file to install WordPress in Bengali an that’s bn_BD.mo.Learn more from here.
Step2:Place files into WordPress folder
We have finished downloading necessary files,now it’s time to place the files into their belonging place.WordPress language file belong to wp-content or wp-includes directory.You can use one of these directory.Here i am using wp-content directory.You will need to create a folder named languages and you must put your language file inside this folder.So path should be something like this WordPress >>wp-content >>languages>>bn_BD.mo.Yes you have to put bn_BD.mo file inside languages folder.See the picture below.

If you are working on a live server log on to your server with Ftp Client and create a new directory inside wp-content directory and name it languages.And then upload bn_BD.mo file inside this newly created directory.We aren’t finished yet.
Step2:Edit your wp-config.php file
The first step we take before installing WordPress is editing wp-config.php file.In this file we put information about our MySQL database.Ok i am not talking more about editing wp-config.php file here.You can learn more about editing wp-config.php form here.Open this little file in your favorite text editing software here i am using Notepad++.Ok lets find these tiny lines in this file.
/**
* WordPress Localized Language, defaults to English.
*
* Change this to localize WordPress. A corresponding MO file for the chosen
* language must be installed to wp-content/languages. For example, install
* de_DE.mo to wp-content/languages and set WPLANG to 'de_DE' to enable German
* language support.
*/
define('WPLANG', '');
Did you find these lines and i think you did.Now you have to edit one line for installing WordPress in Bengali.Just change the last line like bellow
/**
* WordPress Localized Language, defaults to English.
*
* Change this to localize WordPress. A corresponding MO file for the chosen
* language must be installed to wp-content/languages. For example, install
* de_DE.mo to wp-content/languages and set WPLANG to 'de_DE' to enable German
* language support.
*/
define('WPLANG', 'bn_BD');
Here i put bn_BD inside the citation mark which tells WordPress to use the language we putted into languages folder sometimes before.Ok just save this file and open your WordPress installation.You will notice everything in Bengali from your installation window.Like below
