I can use unconfigure command on a previously configured Solaris Unix box and leave it in an unconfigured state. How do I unconfigure CentOS Linux OR RHEL 6.x on HP server. How do I reconfigure the system upon next boot?
You can use sys-unconfig command whoch provides a simple method of reconfiguring a system in a new environment. Upon executing sys-unconfig will halt your system, and run the following configuration programs at boot:
- Change the root password.
- Reconfigure networking / routing.
- Reconfigure time / date / time zone etc.
- Reconfigure Keyboard and mapping.
- Reconfigure system authentication resources.
- Reconfigure system runlevel.
- Reconfigure system services.
Type the following command as root user. Warning: do not type the following command on a production server for just testing purpose. The system will go down immediately:
This command will create a file called /.unconfigured. The presence of this file will cause /etc/rc.d/rc.sysinit to run the programs mentioned above. Also, all persistent rules will be deleted from /etc/udev/rules.d/.
