Linux prohibits Ctrl + Alt + Del restart

Test environment:

CentOS5.X

Centos6.X

 

1. CentOS5.X do not press Ctrl + Alt + Del to restart at the same time

Edit/etc/inittab

Find

CAS: 12345: ctrlaltdel:/sbin/shutdown-t1-a-r now

Change

# Ca: 12345: ctrlaltdel:/sbin/shutdown-t1-a-r now

Or delete the row. Save and exit;

 

Ii. CentOS6.X do not press Ctrl + Alt + Del to restart at the same time

Method 1:

Edit/etc/init/control-alt-delete.conf

Find

Start on control-alt-delete

Change

# Start on control-alt-delete

 

Method 2:

Mv/etc/init/control-alt-delete.conf/etc/init/control-alt-delete.conf.bak

 

 

Note: For all the above methods, many people on the Internet say that after the operation is complete, it takes a restart to take effect. During the testing process, I do not need to restart to take effect immediately.
