You can install the software directly on your machine, which is the traditional and probably best-supported approach. However, there is an alternative which may be easier: Vagrant. This installs the software into a virtual machine, which makes it easier to get a consistent development environment and may avoid installation difficulties. For Vagrant instructions, see [VAGRANT.md](VAGRANT.md).
-These instructions are based on Ubuntu 16.04 LTS, which is the platform used by the OSMF servers.
+These instructions are based on Ubuntu 18.04 LTS, which is the platform used by the OSMF servers.
The instructions also work, with only minor amendments, for all other current Ubuntu releases, Fedora and MacOSX
We don't recommend attempting to develop or deploy this software on Windows. If you need to use Windows, then try developing this software using Ubuntu in a virtual machine, or use [Vagrant](VAGRANT.md).

If you didn't already have PostgreSQL installed then create a PostgreSQL instance and start the server:
bundle install
```
+## Node.js modules
+
+We use [Yarn](https://yarnpkg.com/) to manage the Node.js modules required for the project.
+
+```
+bundle exec rake yarn:install
+```
+
+## Prepare local settings file
+
+This is a workaround. [See issues/2185 for details](https://github.com/openstreetmap/openstreetmap-website/issues/2185#issuecomment-508676026).
+
+```
+touch config/settings.local.yml
+```
+
+## Storage setup
+
+The Rails port needs to be configured with an object storage facility - for
+development and testing purposes you can use the example configuration:
+
+```
+cp config/example.storage.yml config/storage.yml
+```
+
## Database setup
The Rails Port uses three databases - one for development, one for testing, and one for production. The database-specific configuration
### PostgreSQL Functions
-We need to install special functions into the PostgreSQL databases, and these are provided by a library that needs compiling first.
-
-```
-cd db/functions
-make libpgosm.so
-cd ../..
-```
-
-Then we create the functions within each database. We're using `pwd` to substitute in the current working directory, since PostgreSQL needs the full path.
+We need to install some special functions into the PostgreSQL database:
```
-psql -d openstreetmap -c "CREATE FUNCTION maptile_for_point(int8, int8, int4) RETURNS int4 AS '`pwd`/db/functions/libpgosm', 'maptile_for_point' LANGUAGE C STRICT"
-psql -d openstreetmap -c "CREATE FUNCTION tile_for_point(int4, int4) RETURNS int8 AS '`pwd`/db/functions/libpgosm', 'tile_for_point' LANGUAGE C STRICT"
-psql -d openstreetmap -c "CREATE FUNCTION xid_to_int4(xid) RETURNS int4 AS '`pwd`/db/functions/libpgosm', 'xid_to_int4' LANGUAGE C STRICT"
+psql -d openstreetmap -f db/functions/functions.sql
```
### Database structure
bundle exec rails server
```
-You can now view the site in your favourite web-browser at `http://localhost:3000/`

Note that the OSM map tiles you see aren't created from your local database - they are just the standard map tiles.
# Configuration
After installing this software, you may need to carry out some [configuration steps](CONFIGURE.md), depending on your tasks.
+
+# Installing compiled shared library database functions (optional)
+
+There are special database functions required by a (little-used) API call, the migrations and diff replication. The former two are provided as *either* pure SQL functions or a compiled shared library. The SQL versions are installed as part of the recommended install procedure above and the shared library versions are recommended only if you are running a production server making a lot of `/changes` API calls or need the diff replication functionality.
+
+If you aren't sure which you need, stick with the SQL versions.
+
+Before installing the functions, it's necessary to install the PostgreSQL server development packages. On Ubuntu this means:
+
+```
+sudo apt-get install postgresql-server-dev-all
+```
+
+On Fedora:
+
+```
+sudo dnf install postgresql-devel
+```
+
+The library then needs compiling.
+
+```
+cd db/functions
+make libpgosm.so
+cd ../..
+```
+
+If you previously installed the SQL versions of these functions, we'll need to delete those before adding the new ones:
+
+```
+psql -d openstreetmap -c "DROP FUNCTION IF EXISTS maptile_for_point"
+psql -d openstreetmap -c "DROP FUNCTION IF EXISTS tile_for_point"
+```
+
+Then we create the functions within each database. We're using `pwd` to substitute in the current working directory, since PostgreSQL needs the full path.
+
+```
+psql -d openstreetmap -c "CREATE FUNCTION maptile_for_point(int8, int8, int4) RETURNS int4 AS '`pwd`/db/functions/libpgosm', 'maptile_for_point' LANGUAGE C STRICT"
+psql -d openstreetmap -c "CREATE FUNCTION tile_for_point(int4, int4) RETURNS int8 AS '`pwd`/db/functions/libpgosm', 'tile_for_point' LANGUAGE C STRICT"
+psql -d openstreetmap -c "CREATE FUNCTION xid_to_int4(xid) RETURNS int4 AS '`pwd`/db/functions/libpgosm', 'xid_to_int4' LANGUAGE C STRICT"
+```
