EmonHub Failing After Update

pb66 · 13 July 2019 09:01

I suspect it was actually previously pointing at /usr/share/emonhub/emonhub.py . . . as that was the original path and the original symlink is still there.

I had also thought a decision had been made to use an absolute path of

/usr/bin/python /usr/local/bin/emonhub/emonhub.py

but I see no evidence of that in the updates or repos.

That’s not something I’m familiar with I’m afraid.

[edit]

I had a brief look at the updater and assuming (never a good idea) that this bit was successful

              branch=$(git branch | grep \* | cut -d ' ' -f2)
              echo "- git branch: $branch"
              tags=$(git describe --tags)
              echo "- git tags: $tags"
              changes=$(git diff-index HEAD --)
              if [ "$changes" = "" ]; then
                  echo "- no local changes"
                  echo "- running: git pull origin $branch"
                  echo
                  git pull
                  git checkout $branch
                  # relink symlink

This file has been truncated. show original

then this bit must of failed

          # Create backup config.cfg if missing
          cd $emoncms_symlinked_modules/backup
          if [ ! -f config.cfg ]; then
            cp default.config.cfg config.cfg
            user=pi
            emoncms_datadir=/home/pi/data
            emoncms_www=/var/www/emoncms
            sed -i "s~USER~$user~" config.cfg
            sed -i "s~BACKUP_SCRIPT_LOCATION~$usrdir/backup~" config.cfg
            sed -i "s~EMONCMS_LOCATION~$emoncms_www~" config.cfg
            sed -i "s~BACKUP_LOCATION~$usrdir/data~" config.cfg
            sed -i "s~DATABASE_PATH~$emoncms_datadir~" config.cfg
            sed -i "s~EMONHUB_CONFIG_PATH~$usrdir/data~" config.cfg
            sed -i "s~EMONHUB_SPECIMEN_CONFIG~$usrdir/emonhub/conf~" config.cfg
            sed -i "s~BACKUP_SOURCE_PATH~$usrdir/data/uploads~" config.cfg
          fi

but that’s mostly a guess on my part. Some serious rolling up of the sleeves would be needed for me to delve any deeper into that code.

Bottom line, I think is to find where your emoncms modules are located (ie did they get moved successfully) and then check that the default.config.cfg file was duplicated and then edited with all the right paths, I guess.
