Subject: boot process hangs on init of mysqld
When my boot process starts mysqld, it hangs. How can I get it
unstuck? I cannot ssh into the machine because the boot process
hasn't progressed far enough. So, I cannot edit the init scripts to
remove mysqld.
Is there some key-stroke sequence I might be able to try to interrupt
the init.d scripts? I've tried the obvious (ctl-C, ctl-D, etc.)
You'll want to boot into "single user" mode. Try these steps:
1. Boot the machine --- be ready at the console keyboard to press
"e" as in step 2 below.
2. At the GNU GRUB screen, press "e" within 1 - 2 seconds to stop
the boot process, to edit the kernel's boot parameters.
3. Press the down arrow key to highlight the line that looks similar
to the following:
kernel /boot/vmlinuz-2-6.18-4-686 root=/dev/hda1 ro
4. With the highlight on that line, press "e" once again.
5. Screen changes to one where the line can be edited (See "Minmal
BASH-like line editing is supported", and a prompt "grub edit >".)
6. The cursor is at the end of the line, type "single" (the line now
reads thus:)
kernel /boot/vmlinuz-2-6.18-4-686 root=/dev/hda1 ro single
7. Press the Return key.
8. The GNU GRUB screen reappears, press "b" to boot the system.
9. See a few screens of kernel messages, then a prompt "(or type
Control-D to continue:)"
10. Type the root password (if you type Control-D, the boot process
continues as if you weren't booting into single user mode.)
11. See a # shell prompt. Make changes to the init scripts - you
may want to do this with the update-rc.d utility, for help, type
man update-rc.d
12. When done with changes to the init script links, type "exit" at
the # prompt, and the machine continues the boot process as usual.
