Set Automatic startup (rc. local) In Debian)

In Debian, set the Automatic startup (rc. local) -- Linux Release Technology-Debian information. The following is a detailed description. Versions earlier than Debian 4.0 are not like Linux such as Redhat and do not have rc. local file. To enable the startup of a script, you need to build your own rc. local, and you have to set the startup level to be useful.

The Debian system defines 7 running levels from 0 to 6, corresponding to/etc/rc0.d... scripts in the seven directories of/etc/rc6.d. The default running level is 5, which means the following:

Runlevel 0: Shut down and shut down all programs. If the kernel supports APM, the host power can be automatically disabled.
Runlevel 1: in single-user mode, a root shell and read-only file system are provided for system recovery.
Runlevel 2, 3, 4, 5: multi-user mode, set by the user.
Runlevel 6: similar to level 0, it restarts the computer.

Instance, we want to set/usr/bin/vncserver as start-up, you can perform the following operations:
Debian: // touch/etc/init. d/rc. local // create the rc. local file under init. d In debian's initial directory

Write the following content in the rc. local file:
#! /Bin/sh
/Usr/bin/vncserver
Debian: // # chmod + x/etc/init. d/rc. local // give the file executable permission
Debian: // # update-rc.d rc. local start 99 2 3 4 5. stop 01 0 1 6. // set the startup level (required)

To delete the startup level of the script, perform the following operations:
Debian: # update-rc.d-f rc. local remove

In this way, vncserver boot is completed in debian 4.0 and earlier versions.

In Debian 4.0, we will find that the rc. local file already exists in the/etc/init. d directory, and the startup permission has been set. Open this file to understand that the content to be described in this file is to run/etc/rc. local script. We write/usr/bin/vncserver to/etc/rc. the startup item can be added before the EXIT 0 line in the local script.
