-## Software
+### Software
For compiling:
* a recent C++ compiler
Nominatim comes with its own version of osm2pgsql. See the
-osm2pgsql README for additional dependencies required for compiling osm2pgsql.

* [phpunit](https://phpunit.de)
For running Nominatim:
- * [PostgreSQL](http://www.postgresql.org) (9.1 or later)
- * [PostGIS](http://postgis.refractions.net) (2.0 or later)
- * [PHP](http://php.net) (5.4 or later)

+ * [PHP](https://php.net) (7.0 or later)
* PHP-pgsql
* PHP-intl (bundled with PHP)
- * [PEAR::DB](http://pear.php.net/package/DB)
* a webserver (apache or nginx are recommended)
For running continuous updates:
- * [pyosmium](http://osmcode.org/pyosmium/)
+ * [pyosmium](https://osmcode.org/pyosmium/) (with Python 3)
-## Hardware
+### Hardware
A minimum of 2GB of RAM is required or installation will fail. For a full
-planet import 32GB of RAM or more strongly are recommended.
+planet import 32GB of RAM or more are strongly recommended.
-For a full planet install you will need about 600GB of hard disk space (as of
-January 2017, take into account that the OSM database is growing fast). SSD disks
+For a full planet install you will need at least 700GB of hard disk space
+(take into account that the OSM database is growing fast). SSD disks
will help considerably to speed up import and queries.
On a 6-core machine with 32GB RAM and SSDs the import of a full planet takes
a bit more than 2 days. Without SSDs 7-8 days are more realistic.
-# Setup of the server
+## Setup of the server
-## PostgreSQL tuning
+### PostgreSQL tuning
You might want to tune your PostgreSQL installation so that the later steps
make best use of your hardware. You should tune the following parameters in
corruption. Autovacuum must not be switched off because it ensures that the
tables are frequently analysed.
-## Webserver setup
+### Webserver setup
The `website/` directory in the build directory contains the configured
website. Include the directory into your webbrowser to serve php files
from there.
-### Configure for use with Apache
+#### Configure for use with Apache
Make sure your Apache configuration contains the required permissions for the
directory and create an alias:
After making changes in the apache config you need to restart apache.
The website should now be available on http://localhost/nominatim.
-### Configure for use with Nginx
+#### Configure for use with Nginx
Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
