|
|
|
|
##Introduction
|
|
|
|
A image gallery service written in Haskell as a yesod webapp.
|
|
|
|
Visit the test instance at [eidolon.nek0.eu][eidolon]
|
|
|
|
##Installation
|
|
|
|
###Dependencies
|
|
|
|
####Build dependencies
|
|
|
|
A working Haskell capable environment. For that you will need `ghc` and
|
|
`cabal-install`, which you can install with:
|
|
|
|
```bash
|
|
sudo apt-get install ghc cabal-install
|
|
```
|
|
|
|
Now you can set up your cabal with `cabal update` and follow its instructions.
|
|
with this you will have also installed the latest GHC Haskell compiler on your
|
|
system.
|
|
|
|
Additionally to Haskell and its dependencies you will need the following
|
|
software and libraries:
|
|
|
|
* alex
|
|
* happy
|
|
* libpq-dev
|
|
* postgresql
|
|
* libfftw3-dev
|
|
* npm
|
|
* nodejs-legacy
|
|
|
|
which can be installed through
|
|
|
|
```bash
|
|
sudo apt-get install alex happy libpq-dev postgresql npm nodejs-legacy
|
|
```
|
|
|
|
Additionally you need bower, purescript and pulp:
|
|
|
|
```bash
|
|
npm install -g bower
|
|
npm install -g purescript
|
|
npm install -g pulp
|
|
```
|
|
|
|
for migrations also install:
|
|
|
|
* libmagic-dev
|
|
|
|
####Elasticsearch dependencies
|
|
|
|
**WARNING: THIS SECTION IS ONLY VALID FOR VERSIONS >= 0.0.5 and < 0.1.0.0**
|
|
|
|
Since version 0.0.5 there is an Elasticsearch integration for Eidolon. To Be
|
|
able to run eidolon , you need to install `elasticsearch` additionally with:
|
|
|
|
```bash
|
|
sudo apt-get install elasticsearch
|
|
```
|
|
On how to configure your elasticsearch server, look into the
|
|
[elasticsearch documentation][elasticdocu].
|
|
|
|
###Building
|
|
|
|
get the source with
|
|
|
|
```bash
|
|
git clone https://github.com/nek0/eidolon.git
|
|
```
|
|
|
|
build your sandbox with
|
|
|
|
```bash
|
|
cabal sandbox init
|
|
```
|
|
|
|
build the source with
|
|
|
|
```bash
|
|
make all
|
|
```
|
|
|
|
Everything should work automagically from there.
|
|
|
|
##Deploying
|
|
|
|
After compiling you will find an executable called `eidolon` in
|
|
`dist/build/eidolon/eidolon`. Copy or link it anywhere you
|
|
want. The executable needs to be accompanied by the folders `config` and
|
|
`static` and their contents. It's best to copy them to your desired destination.
|
|
|
|
Also check `config/settings.yml` and set the values there accrding to your
|
|
configuration. The field `contactEmail` is optional, you can comment it out, but
|
|
be aware. In certain jurisdictions you are required to give some contact
|
|
information.
|
|
|
|
It may also be necessery to create a reverse proxy to your gallery. I would
|
|
recommend using [nginx](http://nginx.org/).
|
|
|
|
##Customizing
|
|
|
|
Unfortunately the gallery is not highly customizable, but you can change most of
|
|
its appearance by changing the files `static/css/main.css`. Especially the
|
|
default background image can be changed by replacing `static/css/img/bg.jpg`.
|
|
|
|
##Starting
|
|
|
|
You can start the gallery now by running the executable. You need to provide a
|
|
settings file as argument, normally found in `config/settings.yml`
|
|
|
|
Since eidolon will block your console, I recommend wrapping a init-script around
|
|
it. how you can do that is written in my
|
|
[blog](http://nek0.eu/posts/2014-10-23-Daemonize-a-yesod-app.html).

|
##Migrations
|
|
|
|
###0.0.3-0.0.4
|
|
|
|
* do not start or restart your eidolon service before migration
|
|
* run migration script from your run location (where your `static` folder with
|
|
all the images is located)
|
|
* if you are building in a sandbox run
|
|
`runghc -package-db/full/path/to/sandbox/XXX-ghc-version-packages.conf.d
|
|
/path/to/eidolon/Migrations/0.0.3-0.0.4/Migration.hs`
|
|
* Note: No space between the option `-package-db` and its argument
|
|
* without sandbox: `runghc /path/to/eidolon/Migrations/0.0.3-0.0.4/Migration.hs`
|
|
* start or restart your eidolon service
|
|
|
|
###0.0.4-0.0.5
|
|
|
|
* run migration script from your run location (where your `static` folder with
|
|
all the images is located)
|
|
* if you are building in a sandbox run `runghc
|
|
-package-db/full/path/to/sandbox/XXX-ghc-version-packages.conf.d
|
|
/path/to/eidolon/Migrations/0.0.4-0.0.5/Migration.hs`
|
|
* Note: No space between the option `-package-db` and its argument
|
|
* without sandbox: `runghc /path/to/eidolon/Migrations/0.0.4-0.0.5/Migration.hs`
|
|
* start or restart your eidolon service
|
|
|
|
###0.0.7-0.1.0.0
|
|
|
|
You have two options to accomplish the migration:
|
|
1. Build the migration binary with `cabal exec -- ghc --make
|
|
Migrations/0.0.7-0.1.0.0/Migration.hs` and run the executable in your run
|
|
location.
|
|
2. Link the `static/data/` folder from your link location in the same location
|
|
in the project directory and run `cabal exec -- runghc
|
|
Migrations/0.0.7-0.1.0.0/Migration.hs`
|
|
|
|
###0.1.2.4-0.1.3.0
|
|
* Stop Eidolon
|
|
* Log into your database and issue this command:
|
|
`ALTER TABLE "comment" DROP COLUMN "author_slug";`
|
|
* Start Eidolon
|
|
|
|
###0.1.3.3-0.1.4.0
|
|
* Stop eidolon
|
|
* Compile migration script with `cabal exec -- ghc --make Migrations/0.1.3.3-0.1.4.0/Migration.hs`
|
|
* Copy or move compiled script to run location and execute
|
|
* Follow the prompts of the script
|
|
* Start eidolon
|
|
|
|
###0.1.4.0-0.1.5.0
|
|
* Stop eidolon
|
|
* Compile migration script with `cabal exec -- ghc --make Migrations/0.1.4.0-0.1.5.0/Migration.hs`
|
|
* Copy or move compiled script to run location and execute
|
|
* Follow the prompts of the script
|
|
