How to Replace Systemd With SysV Init On Debian Linux

30 November 2017 by Nick Congleton

Objective

Replace systemd with SysV Init as the init system on Debian Stretch

Distributions

Debian Stretch

Requirements

A working Debian Stretch install with root privileges.

Difficulty

Medium

Conventions

# – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command
$ – requires given linux commands to be executed as a regular non-privileged user

Introduction

Not everyone loves systemd, and for those that don’t, there really aren’t many options. That’s especially true if you want something like a stable server. Fear not, SysV Init is actually still supported under Debian, and it’s not hard to switch.

**Note:** don’t try this if you’re running GNOME or another desktop environment that has a hard dependency on systemd. It will just break your system.

Add Devuan Repositories

This part isn’t strictly necessary if you just want to switch the init system and leave systemd installed as a compatibility layer. That would work fine. If you absolutely don’t want systemd on your system at all, you need to make some arrangements to make the things that depend on it work.

Devuan, the systemd-less Debian fork is lagging a bit behind. Their Stretch release, ASCII, isn’t ready, and running Devuan’s testing releases isn’t super stable right now. However, the did build some crucial packages to make systemd-dependent programs work without it, and you can use them in Debian.

First, create a new .list file in /etc/apt/sources.list.d/ for Devuan. Then, add the following line to it.

Installation of the latest bleeding edge PHP 7 on Debian 8 Jessie Linux

27 January 2017 by Lubos Rendek

Introduction

Debian’s current stable package repository may not always contain an up to date software to be in line with
our expectations. There is a very good reason for this, such as a stable system as a trade-off for running bleeding edge software.

PHP server-side scripting language is not an exemption! At
the time of writing the current Debian’s PHP version is 5.6.29 whereas the latest PHP source release is 7.1.0( given that there is no PHP 6 at all ).

The current PHP developer’s claims put PHP 7 in front of PHP 5.6 in terms of speed, where PHP 7 is supposed to be as twice as fast as its predecessor:

Thanks to the new Zend Engine 3.0, your apps see up to 2x faster performance and 50% better memory consumption than PHP 5.6, allowing you to serve more concurrent users without adding any
hardware. Designed and refactored for today’s workloads, PHP 7 is the ultimate choice for web developers today.
Reference: zend.com/en/resources/php-7

Objective

To compare a speed between PHP 5.6 and latest PHP 7.1.0 is not an objective of this article. However, the objective is the get that latest PHP 7 release installed on Debian 8 system. Additionally we
will install PHP-FPM (FastCGI Process Manager). This guide will offer two possible installations.
