Configure Supervisor to run Apache2 webserver on Ubuntu/Debian Linux

The idea about starting your services under Supervisor’s supervision is to be able to run multiple services under a single daemon. Depending on the Supervisor’s configuration it will be able to start,stop or restart any given service as a child process. In this config we show how to runapache2 as supervised service ( useful for docker images etc. ) on Ubuntu/Debian Linux.
First, install supervisor:

# apt-get install supervisor

Include apache2‘s supervisor configuration into /etc/supervisor/conf.d/. Supervisor will pick any configuration files from this directory where the only requirement is *.conf file extension. For example insert a following lines into a new file /etc/supervisor/conf.d/apache2.conf:

command=/usr/sbin/apache2ctl -DFOREGROUND

How to verify an authenticity of downloaded Debian ISO images

There are two steps to verify an authenticity of downloaded Debian ISO images from Debian mirrors:

  1. Firstly, we need to verify check-sum of the CD image content against its relevant checksums files whether it would be MD5SUMS or SHA512SUMS
  2. Secondly, we need to verify the actual checksums files for a correct signature using accompanied signatures such as MD5SUMS.sign or SHA512SUMS.sign

To get started, first download all relevant files including desired ISO images within a single directory. In this case we will validate the authenticity of debian net install CD image:

$ ls
MD5SUMS  MD5SUMS.sign  SHA512SUMS  SHA512SUMS.sign  debian-8.0.0-arm64-netinst.iso
