Set up local mirror of php.net manual

Posted under Technical on December 2nd, 2015 by Vivek Bhat

I am building websites and at times I want to remain disconnected from the internet, but still want to keep looking at PHP, Javascript, jQuery or Bootstrap documentation. So here is what I do to refer php.net documentation even when I am not connected to the internet. What we can do is mirror the official php.net website on our local system. The instructions are there on PHP site on how to set up official mirrors. But these official mirrors have everything, Downloads, etc. Basically a whole copy of php.net, content that we do not need.

Install Oracle 12c on CentOS 7 – Part I

Posted under Technical on September 2nd, 2015 by Vivek Bhat

This is a first part of two series blog on installing Oracle 12c on CentOS 7. First part is about installing CentOS 7 on Virtualbox. In second part we will be installing Oracle 12c on that CentOS machine. You can download CentOS 7 from https://www.centos.org/download. Download DVD ISO or “Everything ISO”. If you downloading DVD ISO, downloading only Part 1 will be sufficient. We would not need Part 2. For Oracle 12c http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html. You will need to have a userid on Oracle and also need to accept the OTN License before allowed to download the files. For Oracle 12c, the downloads are in two parts. Download both of them.

Assumption:Virtual Box is already installed, up and running with guest editions and extensions installed

For this, we need to first install php5-pear and then using pecl, we need to install OCI8. (more…)

Migration Complete

The migration of the site is complete with SEO friendly URLs back in action. I know this is a very long time for site migration, but this was due to severe time constraints I am facing because of professional and personal commitments. Hope to start blogging in full steam soon.
