We made a separate image of ViaMyBox as a web server WordPress for Raspberry Pi. So, you don’t need to waste your time on setting of the components’ connection, which are important for work with the web site. Apache and nginx (for your choice), MySQL (MariaDB), PHP, WordPress are downloaded and set up. Initial settings for optimization of the components are done.
Download image ViaMyBox LAMP (LNMP) on Raspberry Pi. Thus, you will be immediately able to start work form the initialization page of web server WordPress. It is to you to choose. Also you may create your own web site (or copy of your site) from scratch. And this will enable you to work with a test copy. A test copy will allow you to make additions and updates. With no fear to lose your basic web site. By the way, this web site is working on the same platform now.
