Ubuntu OAuth Installation - After astounding success of magento OpenERP Bridge (MOB) we are going to update the next release of magento OpenERP bridge which will support the SOAP, XML-RPC and REST API’s as well .
we were getting some trouble to function OAuth with our ubuntu server and found that there is no concrete guide to install OAuth in Ubuntu Server . So here is the steps which will work 100% for the installation of OAuth .
before installing the OAuth make sure your apt-get is updated properly ? else try to run those command which will update the apt-get also install the PECL support
apt-get update apt-get install php-pear php5-dev
after that you need to run pecl install command for Oauth
pecl install oauth
after that add oauth entry in php.ini file
extension=oauth.so
and final and most important step restart your apache
/etc/init.d/apache2 restart
That’s It .
