RE: Adding a New Service With Systemd/Hello

Hello,

[Unit]
Description=fake2
After=network.target

[Service]
ExecStart=/bin/echo I am starting the fake2 service
ExecStop=/bin/echo I am stopping the fake2 service

[Install]
WantedBy=multi-user.target

This is my fake2.service script from the instructions. I tried to add the service and monitor the service but I cannot find out specific things.

I changed my system a while back for other book purposes. I think this may hinder what I am trying with this instruction from the Linux Foundation.

Anyway,

I have been unable to start, status, and stop the service.

If you need any info. from me, please let me know. It usually prompts me stating unable to resolve host.

Seth

P.S. Please get back to me when anyone out there has time. 4.2 is the Systemd Service section I am reviewing for now.

    Hello,

    my fake2.service at exercise 4.2 looks like the below:

    ----------------------------

    [Unit]

    Description=fake2

    After=network.target

    [Service]

    ExecStart=/bin/sh -c ’/bin/echo I am starting the fake2 service ; /bin/sleep 30’

    ExecStop=/bin/echo I am stopping the fake2 service

    [Install]

    WantedBy=multi-user.target

    -------------------------------------

    If you get any error when you start the service(sudo systemctl start fake2.service), try to change the 

    ExecStart=/bin/sh -c ’/bin/echo I am starting the fake2 service ; /bin/sleep 30’  

    to 

    ExecStart=/bin/sh -c "/bin/echo I am starting the fake2 service ; /bin/sleep 30"


     


    Regards,

    you don't give enough detail to provide much help.  What commands did you run?  Where did you look to see if it ran?  What output do you have?  Also note the script in the solutions is not the same; the ExecStart line looks like:

    ExecStart=/bin/sh -c '/bin/echo I am starting the fake2 service ; /bin/sleep 30'

     

    be careful cutting and pasting because the apostrophes don't always come through correctly.

    Hello Again...I am sorry for the lack of info. I am running Ubuntu 16.04.2/4.4.0-72-generic. It is the LTS version. I will run it again and let you know. Please bear with me here. I will be right back!

    I used the sudo chmod 755 ​command in the shell to attempt to get the fake2.service going. It worked, but it was saying it could not resolve host, well after I disregarded the prompt of ​sudo: could not resolve host (my host name). I then went on to ​sudo systemctl start fake2.service​. The could not resolve host prompt (error message) was stated again when I used the command ​sudo systemctl status fake2.service​. After the command status​, I received a read-out. There was no error message. I then used the command stop. I rebooted and then ran the command status​ again. It read another item of read-outs. That is all. I think I got this one figured out. The systemd system is what I am using. I did not try the SysVinit system.

    Hi,

    Ok, no problem. Just be sure to get information about the error. If you are having errors like 'could not resolve host (my host name)', you need to check the system hostname and see if it's working.

    Regards,

    Luis.

    Hello...I am having an error that states "could not resolve host" and it does not do anything but state that error. I can still update and upgrade for security patches and things of that nature.

    Hi,

    What happens if you execute the 'hostname' command?

    Thanks,

    Luis.

    Hello,

    1) Do 'journalctl -f' in a terminal, while in another run the systemd command. Provide the journalctl ouput.

    2) Please provide a screenshot with the error when running the systemd command.

    Thanks,

    Luis.
