3 This page contains generic installation instructions for Nominatim and its
4 prerequisites. There are also step-by-step instructions available for
5 the following operating systems:
7 * [Ubuntu 18.04](../appendix/Install-on-Ubuntu-18.md)
8 * [Ubuntu 16.04](../appendix/Install-on-Ubuntu-16.md)
9 * [CentOS 7.2](../appendix/Install-on-Centos-7.md)
11 These OS-specific instructions can also be found in executable form
12 in the `vagrant/` directory.
14 Users have created instructions for other frameworks. We haven't tested those
15 and can't offer support.
17 * [Docker](https://github.com/mediagis/nominatim-docker)
18 * [Docker on Kubernetes](https://github.com/peter-evans/nominatim-k8s)
19 * [Ansible](https://github.com/synthesio/infra-ansible-nominatim)
27 * [cmake](https://cmake.org/)
28 * [libxml2](http://xmlsoft.org/)
29 * a recent C++ compiler
31 Nominatim comes with its own version of osm2pgsql. See the
32 [osm2pgsql README](https://github.com/openstreetmap/osm2pgsql/blob/master/README.md#building)
33 for additional dependencies required for compiling osm2pgsql.
37 * [behave](http://pythonhosted.org/behave/)
38 * [Psycopg2](https://initd.org/psycopg)
39 * [nose](https://nose.readthedocs.io)
40 * [phpunit](https://phpunit.de)
42 For running Nominatim:
44 * [PostgreSQL](https://www.postgresql.org) (9.3 or later)
45 * [PostGIS](https://postgis.org) (2.2 or later)
46 * [PHP](https://php.net) (7.0 or later)
48 * PHP-intl (bundled with PHP)
49 * [PEAR::DB](https://pear.php.net/package/DB)
50 * a webserver (apache or nginx are recommended)
52 For running continuous updates:
54 * [pyosmium](https://osmcode.org/pyosmium/) (with Python 3)
58 A minimum of 2GB of RAM is required or installation will fail. For a full
59 planet import 32GB of RAM or more are strongly recommended.
61 For a full planet install you will need at least 700GB of hard disk space
62 (take into account that the OSM database is growing fast). SSD disks
63 will help considerably to speed up import and queries.
65 On a 6-core machine with 32GB RAM and SSDs the import of a full planet takes
66 a bit more than 2 days. Without SSDs 7-8 days are more realistic.
69 ## Setup of the server
73 You might want to tune your PostgreSQL installation so that the later steps
74 make best use of your hardware. You should tune the following parameters in
75 your `postgresql.conf` file.
78 maintenance_work_mem (10GB)
80 effective_cache_size (24GB)
81 synchronous_commit = off
82 checkpoint_segments = 100 # only for postgresql <= 9.4
83 checkpoint_timeout = 10min
84 checkpoint_completion_target = 0.9
86 The numbers in brackets behind some parameters seem to work fine for
87 32GB RAM machine. Adjust to your setup.
89 For the initial import, you should also set:
92 full_page_writes = off
94 Don't forget to reenable them after the initial import or you risk database
95 corruption. Autovacuum must not be switched off because it ensures that the
96 tables are frequently analysed.
100 The `website/` directory in the build directory contains the configured
101 website. Include the directory into your webbrowser to serve php files
104 #### Configure for use with Apache
106 Make sure your Apache configuration contains the required permissions for the
107 directory and create an alias:
109 <Directory "/srv/nominatim/build/website">
110 Options FollowSymLinks MultiViews
111 AddType text/html .php
112 DirectoryIndex search.php
115 Alias /nominatim /srv/nominatim/build/website
117 `/srv/nominatim/build` should be replaced with the location of your
120 After making changes in the apache config you need to restart apache.
121 The website should now be available on http://localhost/nominatim.
123 #### Configure for use with Nginx
125 Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
127 By default php listens on a network socket. If you want it to listen to a
128 Unix socket instead, change the pool configuration (`pool.d/www.conf`) as
131 ; Comment out the tcp listener and add the unix socket
132 ;listen = 127.0.0.1:9000
133 listen = /var/run/php5-fpm.sock
135 ; Ensure that the daemon runs as the correct user
136 listen.owner = www-data
137 listen.group = www-data
140 Tell nginx that php files are special and to fastcgi_pass to the php-fpm
141 unix socket by adding the location definition to the default configuration.
143 root /srv/nominatim/build/website;
144 index search.php index.html;
145 location ~ [^/]\.php(/|$) {
146 fastcgi_split_path_info ^(.+?\.php)(/.*)$;
147 if (!-f $document_root$fastcgi_script_name) {
150 fastcgi_pass unix:/var/run/php5-fpm.sock;
151 fastcgi_index search.php;
152 include fastcgi.conf;
155 Restart the nginx and php5-fpm services and the website should now be available
156 at `http://localhost/`.
159 Now continue with [importing the database](Import-and-Update.md).
