guide/INSTALL.md

Points to keep in mind

The back/state/ directory contains the database. You can download the current database of guide.aelve.com by doing this:

$ make back/db

The back/config.json file contains the config (it will be created at the first start):

• admin-password is the password for the admin panel (at /admin). Leave it empty if you don't want any password.

• google-token lets you set the Google site verification token. Leave it empty if you don't want Google verification.

• base-url is the URL of the server (which should contain http:// or https://). It's used for feed generation.

• discuss-url adds a “discuss this site” link under the header. You can leave it as null.

How to install locally

First install NPM (important!) and libpq. Then do:

$ make back
$ make back/run

And go to http://localhost:8080. The admin page is available at http://localhost:8080/admin.

How to install on a server

I'm going to use Digitalocean and Ubuntu, but you can use anything else.

Create a droplet with Ubuntu. Install Stack (this command will import a GPG key, add Stack's repository, and run apt-get):

$ curl -sSL https://get.haskellstack.org/ | sh

Install NPM and libpq.

Clone and build guide:

$ git clone https://github.com/aelve/guide
$ cd guide
$ make back
$ stack install --fast

Make a new subdomain in Apache. For me, it means writing this to /etc/apache2/sites-available/guide.conf:

<VirtualHost *:80>
  ServerName guide.aelve.com

  ProxyPreserveHost On
  ProxyPass / http://0.0.0.0:8080/
  ProxyPassReverse / http://0.0.0.0:8080/
</VirtualHost>

Enable the remoteip module (this is needed so that the /admin page would display actual IPs instead of 127.0.0.1):

$ a2enmod remoteip

Enable the site:

$ a2ensite guide
$ service apache2 reload

Create a daemon. This goes to /etc/init/guide.conf (the path is going to be something other than /root/guide for you):

start on filesystem or runlevel [2345]
stop on runlevel [!2345]
chdir /root/guide
env LC_ALL=en_US.UTF-8
exec /root/.local/bin/guide

Start the daemon:

$ service guide start

Database

You can set automatic backups of the database to your own repository.

Create .gitignore in the state/ folder:

Archive/
events*
*.lock
*.log

Create a repository locally and remotely. If you're using Github, you can avoid having to enter passwords by generate an access token and using it as username when adding a remote:

$ git remote add origin https://<token>@github.com/aelve/guide-database.git

Next, create upload.sh:

cd /root/guide/state
rm -f *.gz
gzip -k -f *.log
git add -A
GIT_COMMITTER_NAME='auto' GIT_COMMITTER_EMAIL='' git commit --author="auto <>" -m "`date`"
git push

$ chmod +x upload.sh

Finally, make a cron job that would try to upload new data every 10m (though the actual checkpoints are only created once per six hours):

$ crontab -e

*/10 * * * * /bin/bash /root/guide/upload.sh
