Editor to share with you how to boot linux, I hope you have learned a lot after reading this article, let's discuss it together!

1. / etc/rc.local

The rc.local is executed after all the system initialization is completed, so we can write the startup script into it.

This is the easiest way to edit "/ etc/rc.local" and enter the shell command that starts the program (to enter the full path of the command).

Rc.local starts the root account by default. The way to start using other accounts is:

Su-admin-c'/ bin/sh / usr/local/rsync/rsync.sh'

II. Registration system services

Services included in the operating system, such as ssh,ftp, etc., boot automatically.

But if I want to add an installed service as a system service, I can execute the following command:

Put the startup script in the directory / etc/rc.d/init.d

Chkconfig-- add service name

(first, add as a system service, notice that there are two horizontal bars in front of add)

Chkconfig-leve startup level service name on

(note: level 3 represents startup in command line mode, level 5 represents startup in the graphical interface, and on means enabled)

Chkconfig-leve startup level service name off

(note: off means to turn off self-startup)

For example: chkconfig-level 3 mysql on (description: let the mysql service in command line mode, start with the system)

You can also use the chkconfig-- del service name to delete the system service

If you want to see which services are added as system services, you can use the command:

Chkconfig-list/chkconfig

If you want to see which programs are added as self-starting, you can use the command:

Cat / etc/rc.local (see which program paths have been added to this file)
