guys I have a low powered 1U server in my car which collect some data, but when I stop my car and remove my key, the power for the linux box will be cut immediately for the computer. And power back when key is in.
There will be 1-2 MySQL insert per minute into the disk.
- Can I mount OS drive read-only for entire operation? and rest writable, to ensure OS will not be corruption?
- Can I use a UPS to issue shutdown command and restart command when power cuts and back. (never used any UPS)
