### Hardware
A minimum of 2GB of RAM is required or installation will fail. For a full
-planet import 64GB of RAM or more are strongly recommended. Do not report
+planet import 128GB of RAM or more are strongly recommended. Do not report
out of memory problems if you have less than 64GB RAM.
-For a full planet install you will need at least 800GB 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.
+For a full planet install you will need at least 1TB of hard disk space.
+Take into account that the OSM database is growing fast.
+Fast disks are essential. Using NVME disks is recommended.
Even on a well configured machine the import of a full planet takes
-at least 2 days. Without SSDs 7-8 days are more realistic.
-
-## Setup of the server
+around 2 days. On traditional spinning disks, 7-8 days are more realistic.
-### PostgreSQL tuning
+## Tuning the PostgreSQL database
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
work_mem = (50MB)
effective_cache_size = (24GB)
synchronous_commit = off
- checkpoint_segments = 100 # only for postgresql <= 9.4
- max_wal_size = 1GB # postgresql > 9.4
+ max_wal_size = 1GB
checkpoint_timeout = 10min
checkpoint_completion_target = 0.9
fsync = off
full_page_writes = off
-Don't forget to reenable them after the initial import or you risk database
+Don't forget to re-enable them after the initial import or you risk database
corruption.
-### Webserver setup
+## Downloading and building Nominatim
+
+### Downloading the latest release
+
+You can download the [latest release from nominatim.org](https://nominatim.org/downloads/).
+The release contains all necessary files. Just unpack it.
+
+### Downloading the latest development version
+
+If you want to install latest development version from github, make sure to
+also check out the osm2pgsql subproject:
+
+```
+git clone --recursive https://github.com/openstreetmap/Nominatim.git
+```
+
+The development version does not include the country grid. Download it separately:
-The `website/` directory in the build directory contains the configured
-website. Include the directory into your webbrowser to serve php files
-from there.
+```
+wget -O Nominatim/data/country_osm_grid.sql.gz https://nominatim.org/data/country_grid.sql.gz
+```
-#### Configure for use with Apache
+### Building Nominatim
-Make sure your Apache configuration contains the required permissions for the
-directory and create an alias:
+The code must be built in a separate directory. Create the directory and
+change into it.
-``` apache
-<Directory "/srv/nominatim/build/website">
- Options FollowSymLinks MultiViews
- AddType text/html .php
- DirectoryIndex search.php
- Require all granted
-</Directory>
-Alias /nominatim /srv/nominatim/build/website
```
+mkdir build
+cd build
+```
+
+Nominatim uses cmake and make for building. Assuming that you have created the
+build at the same level as the Nominatim source directory run:
-`/srv/nominatim/build` should be replaced with the location of your
-build directory.
-
-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
-
-Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
-
-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:
-
- ; Comment out the tcp listener and add the unix socket
- ;listen = 127.0.0.1:9000
- listen = /var/run/php5-fpm.sock
-
- ; Ensure that the daemon runs as the correct user
- listen.owner = www-data
- listen.group = www-data
- listen.mode = 0666
-
-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.
-
-``` nginx
-root /srv/nominatim/build/website;
-index search.php;
-location / {
- try_files $uri $uri/ @php;
-}
-
-location @php {
- fastcgi_param SCRIPT_FILENAME "$document_root$uri.php";
- fastcgi_param PATH_TRANSLATED "$document_root$uri.php";
- fastcgi_param QUERY_STRING $args;
- fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
- fastcgi_index index.php;
- include fastcgi_params;
-}
-
-location ~ [^/]\.php(/|$) {
- fastcgi_split_path_info ^(.+?\.php)(/.*)$;
- if (!-f $document_root$fastcgi_script_name) {
- return 404;
- }
- fastcgi_pass unix:/var/run/php7.3-fpm.sock;
- fastcgi_index search.php;
- include fastcgi.conf;
-}
```
+cmake ../Nominatim
+make
+sudo make install
+```
+
+!!! 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-<postgresql version>`
+
-Restart the nginx and php5-fpm services and the website should now be available
-at `http://localhost/`.
+Nominatim installs itself into `/usr/local` per default. To choose a different
+installation directory add `-DCMAKE_INSTALL_PREFIX=<install root>` to the
+cmake command. Make sure that the `bin` directory is available in your path
+in that case, e.g.
+```
+export PATH=<install root>/bin:$PATH
+```
-Now continue with [importing the database](Import-and-Update.md).
