contains which programs and which documents; 3. Read the documentation for this package (of course, it is necessary to use the search engine to do some homework first); 4. Just read the source code. In the Red Hat genre system (CentOS, Fedora), the package manager of the software is rpm. Look at CentOS 5.10 First, using the which init command, you can find the full path of Init to/sbin/init, and then use the rpm-qf/sbin/init command, It can be found that the INIT program is in the same package

upstart by sysvinit. Sysvinit is a set of simple shell scripts. It is relatively simple to create and execute processes independently by/sbin/init. Ubuntu uses an upstart System (http://upstart.ubuntu.com) that relies on swap communication, so the execution of the script depends on the execution of/sbin/init. However, UBUNTU/sbni/init requires that its PID be 1; otherwise, it exits directly. Because the ab

To consume electronic Linux systems, you must enable graphical interfaces and other necessary services. unoptimized systems enable many system services that are not used or are currently unavailable by default, this part will spend a lot of time. The simplest optimization method is to customize the system service by rewriting the service con

In short, systemd is an init program. According to the previous Upstart introduction, you should briefly understand the shortcomings of the traditional Sysvinit system. However, the design concept of systemd is more advanced. It can be said that it draws on the idea of launchd on OSX. The init process is started by the kernel. Is it the parent process of all other processes? As a result, more tasks can be done than other processes, such as loading ser

Depending on the system requirements, you may need to create a new service/daemon definition (but it is very likely thatinitngSomeone already does this in the community ). Then you must modify the configuration of LILO or GRUB to point to the new/sbin/initng. To controlinitng, You need to usengc(Comparisontelinit

In recent years, the INIT process of Linux system has undergone two major evolution, the traditional sysinit has gradually faded out of the historical stage, the new upstart and Systemd have their own characteristics, A growing number of Linux distributions have adopted systemd. RHEL 7.0 also started using SYSTEMD.systemd is the latest initialization system (INIT) in Linux, and its main design goal is to overcome the inherent shortcomings of sysinit a

Source: From the ancient yueju blog We have introduced the features and structure of ROS. Next we will begin to prepare for the strong Ros. On the Wiki on the ROS official website, the tutorials for new users are very detailed. It is best to clarify all the tutorials for new users. This is the most basic thing for later development. Despite this, Ros is still difficult for beginners to get started. Here, I will summarize my learning history and serve

Imagine creating a library of wikis. Wiki sites contain content that users can create, delete, and modify interactively. Many wikis feature a simple, text-based markup language for creating content. Typically, these markup languages provide only a subset of the functionality available in HTML, but there is a simpler, clearer source format. For example, text that surrounds the asterisk is formatted as bold, and the underlined text is formatted as an un

In this article, the installation process in the official Wiki is slightly combed, hoping to bring some convenience to those who have just started learning.At the same time, the descriptive narrative in the official Wiki is suffic

I learned how to replace init with upstart in Ubuntu 6.10 before I switched to KUbuntu. The main scripts are in/etc/event. d. By default, there is no inittab file in/etc. When I first installed Kubuntu, I went to/etc/event. d. Take a look at the script rc-default. The script contains the following content: It indicates that inittab does not exist by default, but the inittab created by the user will still be noticed. I learned how to replace init with

originates from a convention in Unix: in Unix, "d" is often used as the suffix identifier of the system daemon. In addition, SystemD also refers to the English term D system, which is used to describe a person's ability to quickly adapt to the environment and solve difficulties.SystemD is designed to improve the disadvantages of SysVinit and compete with upstart of Ubuntu. Many concepts of SystemD come from Apple's launchd. The goal is to start fewer
