By default, if you want to install plugins or upgrade WordPress, you have to provide the FTP details. If you are running WordPress on localhost, you won’t have the FTP credentials. In this case you won’t be able to install plugins or upgrade WordPress. There is a way to configure WP to don’t use FTP, instead install directly using the Read/Write permission of folder.
If WordPress can’t install anything without FTP, it needs another method – direct install. WP will download the required files in a ZIP archive format, extract it to the plugins directory. But WP can’t just move/copy files to a directory of your WP root with out permissions. So you have to change the permissions of your WP root.
Set Write Permission
WP root directory should have the Write permission. You can set the write permission by applying the 0777 permission to the directory. On Linux system, you can do this with the following command :
chmod 0777 /path/to/wordpress-installation
As you can see, you have to mention the WP installation directory location. By doing the above command, the WP folder’s permissions would have Write.
Configure WP To Not Use FTP
The configuration file of WP is wp-config.php, so any settings we are going to set should be in the wp-config.php file. The “No FTP” setting should also be in this file.
Open your WP location. Open the wp-config.php file using a text editor. Add the following code at the end of the file :
/* No FTP : http://subinsb.com/wordpress-no-ftp */ define('FS_METHOD','direct');
Save the file and close the text editor.
Now, try installing a plugin or removing a plugin. WordPress won’t bother you anymore with FTP details form.
