ISG on CentOS 7

This section contains everything you need to know about installing and managing the iconik Storage Gateway (ISG)

1. Download and install the Iconik Storage Gateway

Set up the iconik Yum repository, and install the Iconik Storage Gateway RPM

cd /etc/yum.repos.d
sudo wget https://packages.iconik.io/rpm/7/iconik.repo
sudo yum install iconik_storage_gateway

2. Edit config.ini

Edit /etc/iconik/iconik_storage_gateway/config.ini to look like this (See Setting up how to get the correct values)

[main]

app-id = 22f34c6e-268e-11e7-ac53-6c4008b85488
storage-id = 15fa3f68-7693-11e7-bf0c-02420a021013
iconik-url = https://app.iconik.io/
auth-token = eyJhbGciOiJIUzI1NiIsImlhdCI6MTUwMTU3NjAyNCwiZXhwIjoxNTAxNjE5MjI0fQ.eyJpZCI6IjMzMjFkMjIyLTc2OTMtMTFlNy1hN2EyLTAyNDIwYTAyMTAxYSJ9.sgag4OQb19J9qT1IAdKZYAqbpIoai7oW60Mahye7o8s
sleep-time = 5
max-transcoding-jobs = 5
log-filename = /var/log/iconik/iconik_storage_gateway/default.log
log-use-colors = true
forbidden-dirs = /;//;/etc/*;/dev/*;/cores/*;/bin/*;/sbin/*;/usr/*;/boot/*;/lib/*;/proc/*;/root/*;/run/*;/sys/*
image-magick-config = /etc/iconik/iconik_storage_gateway/image_magick_config
file-upload-parallel-uploads-num = 4
file-download-parallel-downloads-num = 4
missing-files-time-threshold = 60
sqlite-journal-mode = wal
#imagemagick-layer-extensions = .tiff,.tif,.png,.psd,.pdf,.psb
#image-extensions-override = .cr3,.raf,.tif,.tiff,.heic,.hdr

3. Start the service

Iconik Storage Gateway will add a system user called iconik that will be used to run systemd service. The iconik user must have permissions to read/write the storage mount point folder and it contents. You can add the iconik user to a group to manage permissions on group level instead.

After installation you can start service with:

sudo systemctl enable iconik_storage_gateway
sudo systemctl start iconik_storage_gateway

To check status of the service use:

sudo systemctl status iconik_storage_gateway

For following the log file, you can use the following command:

sudo tail -f /var/log/iconik/iconik_storage_gateway/default.log

You can run also run the systemd service from your custom user by providing an override (sudo systemctl edit iconik_storage_gateway.service) passing your own config and log files that are accessible for your custom user. Log file location can also be set in config.

[Service]
User=john
Group=john

ExecStart=/usr/bin/iconik_storage_gateway --config=/home/john/iconik_storage_gateway/config.ini --log-filename=/home/john/iconik_storage_gateway/default.log

You will need to give your new user permissions to the database file and the log directory as well (If you didn't change the logs)

sudo chown -R john:john /var/iconik/iconik_storage_gateway/
sudo chown -R john:john /var/log/iconik/iconik_storage_gateway/

After adding your custom user you need to restart service.

sudo systemctl daemon-reload
sudo systemctl restart iconik_storage_gateway

Local transcoding

Local transcoding is required for viewing your content in the web browser

For local transcoding to work you will have to install ffmpeg, poppler and ImageMagick. Make sure they are in the path for the user running the service.

Below is one way of doing so, but please do not use on a production setup without checking compatibility with other software:

sudo yum install epel-release -y
sudo yum update -y
sudo rpm -Uvh https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.noarch.rpm
sudo yum install ffmpeg ffmpeg-devel ImageMagick poppler-utils ghostscript ufraw -y

Alternatively, you can download a static build of ffmpeg which doesn't require any additional libraries. This is available from https://johnvansickle.com/ffmpeg/

To get frame accurate playback in other browsers than Safari you also need mp4mux from Bento4.

You can download binaries from https://www.bento4.com/downloads/ but the latest version does not work properly on CentOS 7. Please use the version available at http://zebulon.bok.net/Bento4/binaries/Bento4-SDK-1-5-1-628.x86_64-unknown-linux.zip instead.

Unpack the correct package, and copy the mp4mux binary to /usr/local/bin

To write xmp metadata which can be used in our adobe integration to the proxy files you need Exiftool

sudo yum install perl-Image-ExifTool

Update the storage settings in Iconik to say Local keyframes and Local proxy and restart the service.
