### Hardware
A minimum of 2GB of RAM is required or installation will fail. For a full
means that PostgreSQL needs to run checkpoints less often but it does require
the additional space on your disk.
+Autovacuum must not be switched off because it ensures that the
+tables are frequently analysed. If your machine has very little memory,
+you might consider setting:
+
+ autovacuum_max_workers = 1
+
+and even reduce `autovacuum_work_mem` further. This will reduce the amount
+of memory that autovacuum takes away from the import process.
+
For the initial import, you should also set:
fsync = off
full_page_writes = off
Don't forget to reenable them after the initial import or you risk database
-corruption. Autovacuum must not be switched off because it ensures that the

### Webserver setup
Make sure your Apache configuration contains the required permissions for the
directory and create an alias:
- <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
+``` 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
+```
`/srv/nominatim/build` should be replaced with the location of your
build directory.
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.
- root /srv/nominatim/build/website;
- index search.php index.html;
- location ~ [^/]\.php(/|$) {
- fastcgi_split_path_info ^(.+?\.php)(/.*)$;
- if (!-f $document_root$fastcgi_script_name) {
- return 404;
- }
- fastcgi_pass unix:/var/run/php5-fpm.sock;
- fastcgi_index search.php;
- include fastcgi.conf;
+``` 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;
+}
+```
Restart the nginx and php5-fpm services and the website should now be available
at `http://localhost/`.
