[SOLVED] Logview on ubuntu

buumann · September 25, 2018, 9:38pm

Hi,

first, i want to fix error to start frontail service. I have changed the user and group to openhab.
And fixed the path in frontail.service to /usr/local/bin.
But the service did not start with code 127.

I can start it with “/usr/local/bin/frontail --ui-highlight -t dark /var/log/openhab2/openhab.log”
and the service is running.

Can you help to debug.

When you log in your ubuntu device, what is your username
Can you show me the service status?

buumann · September 26, 2018, 6:31am

My username is “user”.
Here is the the output:

Can you post your .service file, please?

buumann · September 26, 2018, 7:04am

frontail.service file contains:

[Unit]
Description=Frontail

[Service]
ExecStart=/usr/local/bin/frontail --ui-highlight -t dark /var/log/openhab2/open$
Restart=always
User=openhab
Group=openhab

WorkingDirectory=/usr/local/bin/

[Install]

vzorglub · September 26, 2018, 7:07am

change openhab to user

then

sudo chmod 644 /lib/systemd/system/frontail.service
sudo systemctl daemon-reload
sudo systemctl stop fronttail.service
sudo systemctl enable frontail.service
sudo systemctl start frontail.service

buumann · September 26, 2018, 7:12am

i changed from openhab to user, here the output:

vzorglub · September 26, 2018, 7:14am

Look good
Does it work?

vzorglub · September 26, 2018, 7:24am

Why are you working in root?
Try to avoid that, it is quite dangerous

buumann · September 26, 2018, 7:27am

I switched back to user
but the service did not start:

Ok, try to use the code fences, please

Change the frontail.service file:
I have changes the last lines in the [Service] section

[Unit]
Description=Frontail

[Service]
ExecStart=/usr/local/bin/frontail --ui-highlight -t dark /var/log/openhab2/open$
Restart=always
User=openhab
Group=openhab
Environment=PATH=/usr/local/bin/frontail
Environment=NODE_ENV=production
WorkingDirectory=/usr/local/bin/frontail

[Install]
WantedBy=multi-user.target
Alias=frontail.service

buumann · September 26, 2018, 8:38am

i changed the file, and do reboot, but same problem.
here the service

[Unit]
Description=Frontail

[Service]

i use the newest ubuntu server 18.04.01 lts

vzorglub · September 26, 2018, 10:50am

Sorry. But I don’t know anymore
My set-up is exactly as your Ubuntu Server 18.04.01 lts
And apart from the directory it is the same as yours

Benjy · September 26, 2018, 11:29am

I’ve not used fronttail, but you may get more information about the error using the command:

sudo journalctl -u fronttail.service -b

The latest attempt at startup would be at the bottom.

buumann · September 26, 2018, 11:51am

thanks, for the command, i find that the

Environment=PATH=/usr/local/bin/frontail
and
WorkingDirectory=/usr/local/bin/frontail

did not exist, i changed it back to:

Environment=PATH=/usr/local/bin/frontail

WorkingDirectory=/usr/local/bin/frontail

After that, the log shows a problem with the env/ node:

Sep 26 13:43:09 ubuntu-18-openhab2 systemd[1]: Stopped Frontail.
Sep 26 13:43:09 ubuntu-18-openhab2 systemd[1]: Started Frontail.

vzorglub · September 26, 2018, 1:36pm

did you install nodejs?

buumann · September 26, 2018, 2:01pm

yep, it is installed via “apt-get install nodejs”

buumann · September 26, 2018, 2:23pm

I found the sulution, the directorys are failed,
here is the working fontail.service:

[Unit]
Description=Frontail

[Service]
ExecStart=/usr/local/bin/frontail --ui-highlight -t dark /var/log/openhab2/openhab.log /var/log/openhab2/events.log
Restart=always
User=user
Group=user
Environment=PATH=/usr/local/bin/frontail
Environment=NODE_ENV=production
WorkingDirectory=/usr/local/bin/frontail

[Install]
WantedBy=multi-user.target
Alias=frontail.service

Thanks very much to the community to find the Solution!!!

Hi All

I can get this to start and display the logs with the config below, but there is no working directory or environment paths because I just could not get the darn thing to start with the entires above. What are they needed for? Using NGINX I cannot get to http://192.168.0.3/frontail


}
location /frontail/ {
    proxy_pass http://localhost:9001;
    proxy_set_header Host                   $http_host;
    proxy_set_header X-Real-IP              $remote_addr;
    proxy_set_header X-Forwarded-For        $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto      $scheme;
}


[Unit]
Description=Frontail

[Service]
ExecStart=/usr/local/bin/frontail --ui-highlight -t dark /var/log/openhab2/openhab.log /var/log/openhab2/events.log /var/log/openhab2/zwave.log

Don’t know if you solved this, but you need to use frontail with --url-path /frontail for it to work through nginx
