+### Downloading the latest release
-The `website/` directory in the build directory contains the configured

-from there.
+You can download the [latest release from nominatim.org](https://nominatim.org/downloads/).
+The release contains all necessary files. Just unpack it.

+If you want to install latest development version from github, make sure to

- AddType text/html .php
- DirectoryIndex search.php
- Require all granted
-
- Alias /nominatim /srv/nominatim/build/website
+```
+git clone --recursive https://github.com/openstreetmap/Nominatim.git
+```
-`/srv/nominatim/build` should be replaced with the location of your
-build directory.
+The development version does not include the country grid. Download it separately:
-After making changes in the apache config you need to restart apache.
-The website should now be available on http://localhost/nominatim.
+```
+wget -O Nominatim/data/country_osm_grid.sql.gz https://www.nominatim.org/data/country_grid.sql.gz
+```
-#### Configure for use with Nginx
+### Building Nominatim
-Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
+The code must be built in a separate directory. Create the directory and
+change into it.
-By default php listens on a network socket. If you want it to listen to a
-Unix socket instead, change the pool configuration (`pool.d/www.conf`) as
-follows:
+```
+mkdir build
+cd build
+```
- ; Comment out the tcp listener and add the unix socket
- ;listen = 127.0.0.1:9000
- listen = /var/run/php5-fpm.sock
+Nominatim uses cmake and make for building. Assuming that you have created the
+build at the same level as the Nominatim source directory run:
- ; Ensure that the daemon runs as the correct user
- listen.owner = www-data
- listen.group = www-data
- listen.mode = 0666
+```
+cmake ../Nominatim
+make
+sudo make install
+```
-Tell nginx that php files are special and to fastcgi_pass to the php-fpm
-unix socket by adding the location definition to the default configuration.
+!!! warning
+ The default installation no longer compiles the PostgreSQL module that
+ is needed for the legacy tokenizer from older Nominatim versions. If you
+ are upgrading an older database or want to run the
+ [legacy tokenizer](../customize/Tokenizers.md#legacy-tokenizer) for
+ some other reason, you need to enable the PostgreSQL module via
+ cmake: `cmake -DBUILD_MODULE=on ../Nominatim`. To compile the module
+ you need to have the server development headers for PostgreSQL installed.
+ On Ubuntu/Debian run: `sudo apt install postgresql-server-dev-`
