I’m having trouble with getting the local server to start after restarting my Raspberry Pi. I’m wondering if I haven’t modified the rc.local file correctly. Any help would be appreciated. My file is as follows:
#! /bin/sh
### BEGIN INIT INFO
# Provides: rc.local
# Required-Start: $all
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop:
# Short-Description: Run /etc/rc.local if it exist
### END INIT INFO
PATH=/sbin:/usr/sbin:/bin:/usr/bin
. /lib/init/vars.sh
. /lib/lsb/init-functions
do_start() {
if [ -x /etc/rc.local ]; then
[ "$VERBOSE" != no ] && log_begin_msg "Running local boot scripts (/etc/rc.local)"
/etc/rc.local
ES=$?
[ "$VERBOSE" != no ] && log_end_msg $ES
return $ES
fi
}
case "$1" in
start)
do_start

Yes, can be frustrating as far as I have found! Mind you I’m not a Linux user …
I ended up using Bitvise and ssh into the pi.
Your rc.local file is exactly as mine…
I copied over the server file and in the end had it in /home and /home/pi and in /home/pi/Blynk! Obviously doesn’t need them all, but I really can’t be salted to worry about a few meg.
Initial attempts just kicked the server out with bj errors.
My /home contains logs and pi dirs. logs are old. Can’t find new logs.
Pi contains Blynk which contains /data… holds user data.
Runs fine now, so I can get on with my projects!
I am not sure about Java, but with python I have to create a bash script that launches the Python script and put the bash script as the cron task instead of the Python script directly. I bit of a messy work around, but it works…
For others having this issues, make sure your server files are located where you are setting your directory. For example, I have all of my files located at /home/pi/Blynk/. My crontab file is as follows:
