I have problems starting my simple raspberry pi script automatically after reboot.
I did the following steps:
cd /etc/init.d
sudo nano myStartScript2.sh
sudo chmod +x /etc/init.d/myStartScript2.sh
sudo chmod 755 /etc/init.d/myStartScript2.sh
sudo update-rc.d myStartScript2.sh defaults
script looks like this:
#!/bin/sh
### BEGIN INIT INFO
# Provides: myStartScreen2
# Required-Start:
# Required-Stop:
# Should-Start:
# Default-Start: S
# Default-Stop:
# Short-Description: Show custom splashscreen
# Description: Show custom splashscreen
### END INIT INFO
echo "this is called at boot"
sleep 5
cd /home/pi/Desktop/mjpg-streamer-experimental
export LD_LIBRARY_PATH=.
./mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so -x 1020 -y 550 -fps 20 -hf -vf -ex night"
If I look in the folder /etc/rcS.d , I can find myStartScript2.sh.
But it is not getting executed after reboot. What am I missing?
As it stands, your script only runs in single-user mode, but I assume you want it to run in normal, i.e. multi-user mode? If so, first of all run:
sudo update-rc.d myStartScript2.sh remove
to get rid of the redundant link in /etc/rcS.d. Then change your line:
# Default-Start: S
to
# Default-Start: 5
Run
sudo update-rc.d myStartScript2.sh defaults
It should have created a link in /etc/rc5.d. Try re-booting.

I'm trying to use the Dockerfile provided here and on building docker build . I get the error on line 69 (RUN createuser -s projop) which reports:
Step 15/27 : RUN /usr/bin/pg_ctl -D "/var/lib/pgsql/data" start
---> Using cache
---> ce049ebe4ff5
Step 16/27 : RUN sleep 60
---> Using cache
---> bf7bac638da6
Step 17/27 : RUN createuser -s projop # database user "projop" with admin rights
---> Running in 700e6e618060
createuser: could not connect to database postgres: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
My inital thought was the the postgres server had not had enough time to start up from the lines before so I extended the sleep command up to 60 seconds, but I still got this same error.
I also opened a bash session with a intermediate container after the sleep with docker run -it bf7bac638da6 bash. Within this bash session I tried to manually run the createuser -s projop line which gave the same error.
However, if I reran the command /usr/bin/pg_ctl -D "/var/lib/pgsql/data" start and then createuser -s projop it would work.
This is quite od as it seems the initial start command is not taking effect. Any ideas what might be happening here?

How to install the latest MongoDB 3.4 or even 3.6?
They support with Ubuntu, but my server is Debian Buster and I am stuck with MongoDB 3.2.
I don't know if this is a good idea yet, but I just installed it by adding the sid repos and installing using the mongodb-server package. For me this installs version 3.4.18.
I created /etc/apt/sources.list.d/sid.list with:
deb http://deb.debian.org/debian/ sid main
deb-src http://deb.debian.org/debian/ sid main
then did
apt update
apt install mongodb-server
and verified that it's working by connecting with mongo.
I have found the solution for a build script, the description is found here:
https://github.com/patrikx3/docker-debian-testing-mongodb-stable
The description:
Debian Stretch / Buster / Bullseye / Testing MongoDB and MongoDB Tools build stable builder script, what it does as exactly:
It is basically a built for the latest MongoDB for Debian.
The current varsion is the r4.0.x build (release).
Warning It will remove all mongodb* apt packages in ./scripts/build-server.sh and /etc/systemd/system/mongodb-server.service is replaced.
It install the required apt dependencies and generates the SystemD service and makes it enabled.
Check if the build works (building is below). It runs all tests, so if it works, then it really does, actually. If there is an error, of course, you will not deploy on your server. So, if building and testing works, then it puts the binaries as it follow and you are sure and done.
The build as follows build-server.sh:
#!/usr/bin/env bash
# based on https://github.com/mongodb/mongo/wiki/Build-Mongodb-From-Source
# the current directory
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
# if an error exit right away, don't continue the build
set -e

I'm trying to run 3 services at my container startup (snmpd, sshd and centengine)
As runlevel is unknown in the container, services won't start.
I built an image with this Dockerfile :
FROM centos:6.7
MAINTAINER nael <me#mail>
# Update CentOS
RUN yum -y update
# Install wget
RUN yum install -y wget
# Get Centreon Repo
RUN wget http://yum.centreon.com/standard/3.0/stable/ces-standard.repo -O /etc/yum.repos.d/ces-standard.repo
# Install Packages (SSH, sudo, Centreon Poller & Engine, SNMP)
RUN yum install -y --nogpgcheck openssh-clients openssh-server centreon-poller-centreon-engine sudo net-snmp net-snmp-utils
# Install supervisord
RUN rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
RUN yum --enablerepo=epel install -y supervisor
RUN mv -f /etc/supervisord.conf /etc/supervisord.conf.org
ADD supervisord.conf /etc/
# For sshd & centengine
EXPOSE 22 5669
# Change user password
RUN echo -e "password" | (passwd --stdin user)
# Disable PAM (causing issues while ssh login)
RUN sed -ri 's/UsePAM yes/#UsePAM yes/g' /etc/ssh/sshd_config
RUN sed -ri 's/#UsePAM no/UsePAM no/g' /etc/ssh/sshd_config
# Start supervisord
CMD ["/usr/bin/supervisord"]
Here is the supervisord.conf file
[supervisord]
nodaemon=true
pidfile=/var/run/supervisord.pid
logfile=/var/log/supervisor/supervisord.log
[program:centengine]
command=service centengine start
[program:snmpd]
command=service snmpd start
[program:sshd]
command=service sshd start
But with this Dockerfile and supervisord.conf, when I start my container theses services aren't running.
What could be the problem ?
Not anymore using supervisord.
I just include a script with all the services ... start commands in the Dockerfile. When I create my container with docker run ... I just specify that I want to start it with my script.
& that's working very well.
Thanks #warmoverflow for trying to solve this.
You may find my dockerfy utility useful starting services, pre-running initialization commands before the primary command starts. See https://github.com/markriggins/dockerfy
For example:
RUN wget https://github.com/markriggins/dockerfy/releases/download/0.2.4/dockerfy-linux-amd64-0.2.4.tar.gz; \
tar -C /usr/local/bin -xvzf dockerfy-linux-amd64-*tar.gz; \
rm dockerfy-linux-amd64-*tar.gz;
ENTRYPOINT dockerfy
COMMAND --start bash -c "while false; do echo 'Ima Service'; sleep 1; done" -- \
--reap -- \
nginx
Would run a bash script as a service, echoing "Ima Service" every second, while the primary command nginx runs. If nginx exits, then the "Ima Service" script will automatically be stopped.
As an added benefit, any zombie processes left over by nginx will be automatically cleaned up.
You can also tail log files such as /var/log/nginx/error.log to stderr, edit nginx's configuration prior to startup and much more
I would like to connect to a VPN on start-up of OSMC.
Environment:
installed OSMC on Raspberry 2
downloaded, compiled and installed shrew soft vpn on the device
As user 'osmc' with ssh
> sudo iked starts the daemon successfully
> ikec -r "test.vpn" -a starts the client, loads the config and connects successfully
rc.local:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sudo iked >> /home/osmc/iked.log 2>> /home/osmc/iked.error.log &
ikec -a -r "test.vpn" >> /home/osmc/ikec.log 2>> /home/osmc/ikec.error.log &
exit 0
after start of raspberry iked is as process visible with ps -e
but ikec is not running
osmc#osmc:~$ /etc/rc.local starts the script and connects to vpn successfully
Problem:
Why does the script not working correctly on start-up?
Thank you for your help!
I was also looking to do the same thing as you and ran into the same problem. I'm no linux expert, but I did figure out a workaround.
I created a script called ikec_after_reboot.sh and it looks like this...
$ cat ikec_after_reboot.sh
#!/bin/bash
echo "Starting ikec"
ikec -r test.vpn -a
I then installed cron.
sudo apt-get update
sudo apt-get install cron
Edit the cron job as root and run the ikec script 60 seconds after reboot.
sudo crontab -e
SHELL=/bin/bash
#reboot sleep 60 && /home/osmc/ikec_after_reboot.sh & >> /home/osmc/ikec.log 2>&1
Now edit your /etc/rc.local file and add the following.
sudo iked >> //home/osmc/iked.log 2>> /home/osmc/iked.error.log &
exit 0
Hopefully, this is helpful to you.
My name Trang,
I have created Docker image on https://registry.hub.docker.com/u/trangunghoa/railo-mysql/
It is run ok.
Now I created Dockerfile but I can't start automatic Railo service. Please help me.
I have start by some commands at shell script:
exec /opt/railo/railo_ctl start
exec /opt/railo/railo_ctl start -D FOREGROUND
service railo_ctl restart
exec service railo_ctl restart
No command it work.
I looked inside your Dockerfile and identified the problem.
You can only use one CMD inside a Dockerfile. (if you use multiple CMD the old one will override) More info : https://docs.docker.com/reference/builder/#cmd
You need to know that Docker isn't made for running multiple process without a little bit of help. I suggest using supervisord : https://docs.docker.com/articles/using_supervisord/
You can't use RUN service inside a Dockerfile, the reason is simple the command service will be executed and start a daemon, then notify the execution was successful. The temporary container will be killed (and the daemon too) and after that the change will be committed.
What your Dockerfile should look like :
