Notes on setting up Raspberry Pi 2
This post describes the stuff I did to my Raspberry Pi 2, which is the current acting home server. These configuration steps are probably useful for everyone.
- Download and flash the Raspbian-lite image.
- Remove the following packages:
dhcpcd5 dphys-swapfile raspi-config triggerhappy bluez*
/etc/network/interfaces- it makes configuring the network more complicated.
dphys-swapfileconfigure a swap file in the root partition - I have no idea why anyone wants that.
triggerhappynot entirely sure what it does, probably useless - I have never used it.
raspi-configmesses with your CPU frequency governor at boot, of course you want to use the
bluez*are the Bluetooth related things. I don't use Bluetooth.
- Wipe the unnecessary stuff in
/etc/rc.local, so your IP address doesn't come up in the boot screen - I found it weird.
- Install 'default-mta', of course you want to receive all the system emails.
- Add the following in
/etc/sysfs.conf, these ensures that your CPU always runs at the fastest speed. You should be using zswap anyway.
devices/system/cpu/cpu0/cpufreq/scaling_governor = performance devices/system/cpu/cpu1/cpufreq/scaling_governor = performance devices/system/cpu/cpu2/cpufreq/scaling_governor = performance devices/system/cpu/cpu3/cpufreq/scaling_governor = performance module/zswap/parameters/enabled = 1
