Analysis of Linux init system initialization, analysis of init In recent years, the init process of Linux has undergone two major evolution, and the traditional sysvinit has gradually faded out of the historical stage. The new UpStart and systemd have their own characteristics, more and more Linux distributions adopt systemd. This article briefly introduces the

Linux Kernel EMD -- start/stop/restart the service in RHEL/CentOS 7 One of the major changes in RHEL/CentOS 7.0 is switching to systemd. It is used to replace SysV and Upstart in the previous versions of Red Hat Enterprise Edition Linux to manage systems and services. Systemd is compatible with the startup scripts of SysV and Linux Standard groups.

Test environment: CentOS6.6 x86_64Accidentally found after deleting/etc/inittab file can still enter the system, I remember the 5 series will pop up a dialog to select the RunLevel. So I studied it a bit.#之前走了一点弯路, mistakenly think that control is done in the/sbin/init binary program, downloaded the upstart source package, the results did not understand how to read-_-!#后来发现控制过程在shell脚本里.#不过也算有一点收获SRC.RPM Decompression Source MethodRpm2cpio XXX.src.rpm

, using the which init command, you can find out that the full path to Init is/sbin/init, and then use the sudo dpkg-s/sbin/init command to find out which package for the INIT program is upstart Finally, using the sudo dpkg-l upstart command, you can see what programs are in this package, which documents and where they are located in the filesystem, such as:Study CentOS 6.5 In the same way, and discover tha

replace sysinit and upstart completely, there is no such thing as a voice against them, but these people have to make systemd the commanding heights and become the industry standard." ”Multiple kernel supportThere is a market for distributions that focus on a single point. Chris Travers said."These distributions will build their own systems for one server scenario and will be kernel-optimized, but they wil

service to be started in parallel, which speeds up the boot speed. But people think it is not fast enough, so there is a systemd, it can be through a certain technology and skills to enable the related services can also be started concurrently, of course, the result is systemd more complex. Here we only mention the speed of the launch, of course, there are other improvements, for details, please refer to:
