浅析 Linux 初始化 init 系统：sysvinit

由 邮差的信 提交于 2019-12-07 17:10:38
从 sysvinit 到 systemd 近年来， Linux 系统的 init 进程经历了两次重大的演进，传统的 sysvinit 已经淡出历史舞台，新的 init 系统 UpStart 和 systemd 各有特点，而越来越多的 Linux 发行版采纳了 systemd。本文简要介绍了这三种 init 系统的使用和原理，每个 Linux 系统管理员和系统软件开发者都应该了解它们，以便更好地管理系统和开发应用。本文是系列的第一部分，主要讲述 sysvinit 的特点和使用。 什么是 Init 系统,init 系统的历史和现状 Linux 操作系统 的启动首先从 BIOS 开始，接下来进入 boot loader ，由 bootloader 载入 内核 ，进行 内核初始化 。 内核初始化 的最后一步就是启动 pid 为 1 的 init 进程。这个进程是系统的第一个进程。它负责产生其他所有用户进程。 init 以守护进程方式存在，是所有其他进程的祖先。init 进程非常独特，能够完成其他进程无法完成的任务。 Init 系统能够定义、管理和控制 init 进程的行为。它负责组织和运行许多独立的或相关的始化工作(因此被称为 init 系统)，从而让计算机系统进入某种用户预订的运行模式。 仅仅将内核运行起来是毫无实际用途的，必须由 init 系统将系统代入可操作状态。比如启动外壳

Approach for installing system service implemented as Ruby gem

由 ε祈祈猫儿з 提交于 2019-12-07 15:24:23
问题 After years of being away from Ruby, I'm back full-force and have just cut my first gem, which includes an executable. Everything works like a charm. The problem I am facing, however, is that I ALSO have a startup script (not part of the gem istelf) that daemonizes the executable. Additionally, I'd also like for the startup script to point the executable at configuration in a place like /var/ To the best of my knowledge, there's no way with rubygems, gemspec, etc., to specify files getting
