Setting up the system

Before starting, we must set up our embedded board by installing all the going to use the BeagleBone Black to test the code; however, as already stated earlier, every command or program used here can be used indifferently on the other embedded boards too.

First of all, we have to install the command-line interpreter for the PHP scripting language and the related plugin for the Apache web server. We can do it using the usual aptitude command, as follows:

root@bbb:~# aptitude install php5-cli libapache2-mod-php5

Then, a package for the Python interpreter proves to be useful in creating daemons:

root@bbb:~# aptitude install python-daemon

Then, we have to install the following packages for xinetd:

root@bbb:~# aptitude install xinetd telnet

For MySQL, we need the following packages:

root@bbb:~# aptitude install mysql-client mysql-server

Note

During the installation of the preceding MySQL packages, the system should ask for an administrative root user. This is not the system's root user, but it's the root user of the MySQL server, so we should put a different password from the system's root user (even if it's not required at all).

Then, we need some extra packages to add some libraries to talk with the MySQL daemon in C, PHP, and Python languages. Here is the command to install these packages:

root@bbb:~# aptitude install libmysqlclient-dev php5-mysqlnd python-mysqldb
