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 for additional dependencies required for compiling osm2pgsql.
36 * [behave](http://pythonhosted.org/behave/)
37 * [Psycopg2](https://initd.org/psycopg)
38 * [nose](https://nose.readthedocs.io)
39 * [phpunit](https://phpunit.de)
41 For running Nominatim:
43 * [PostgreSQL](https://www.postgresql.org) (9.3 or later)
44 * [PostGIS](https://postgis.org) (2.2 or later)
45 * [PHP](https://php.net) (7.0 or later)
47 * PHP-intl (bundled with PHP)
48 * [PEAR::DB](https://pear.php.net/package/DB)
49 * a webserver (apache or nginx are recommended)
51 For running continuous updates:
53 * [pyosmium](https://osmcode.org/pyosmium/) (with Python 3)
57 A minimum of 2GB of RAM is required or installation will fail. For a full
58 planet import 32GB of RAM or more are strongly recommended.
60 For a full planet install you will need at least 700GB of hard disk space
61 (take into account that the OSM database is growing fast). SSD disks
62 will help considerably to speed up import and queries.
64 On a 6-core machine with 32GB RAM and SSDs the import of a full planet takes
65 a bit more than 2 days. Without SSDs 7-8 days are more realistic.
68 ## Setup of the server
72 You might want to tune your PostgreSQL installation so that the later steps
73 make best use of your hardware. You should tune the following parameters in
74 your `postgresql.conf` file.
77 maintenance_work_mem (10GB)
79 effective_cache_size (24GB)
80 synchronous_commit = off
81 checkpoint_segments = 100 # only for postgresql <= 9.4
82 checkpoint_timeout = 10min
83 checkpoint_completion_target = 0.9
85 The numbers in brackets behind some parameters seem to work fine for
86 32GB RAM machine. Adjust to your setup.
88 For the initial import, you should also set:
91 full_page_writes = off
93 Don't forget to reenable them after the initial import or you risk database
94 corruption. Autovacuum must not be switched off because it ensures that the
95 tables are frequently analysed.
99 The `website/` directory in the build directory contains the configured
100 website. Include the directory into your webbrowser to serve php files
103 #### Configure for use with Apache
105 Make sure your Apache configuration contains the required permissions for the
106 directory and create an alias:
108 <Directory "/srv/nominatim/build/website">
109 Options FollowSymLinks MultiViews
110 AddType text/html .php
111 DirectoryIndex search.php
114 Alias /nominatim /srv/nominatim/build/website
116 `/srv/nominatim/build` should be replaced with the location of your
119 After making changes in the apache config you need to restart apache.
120 The website should now be available on http://localhost/nominatim.
122 #### Configure for use with Nginx
124 Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
126 By default php listens on a network socket. If you want it to listen to a
127 Unix socket instead, change the pool configuration (`pool.d/www.conf`) as
130 ; Comment out the tcp listener and add the unix socket
131 ;listen = 127.0.0.1:9000
132 listen = /var/run/php5-fpm.sock
134 ; Ensure that the daemon runs as the correct user
135 listen.owner = www-data
136 listen.group = www-data
139 Tell nginx that php files are special and to fastcgi_pass to the php-fpm
140 unix socket by adding the location definition to the default configuration.
142 root /srv/nominatim/build/website;
143 index search.php index.html;
144 location ~ [^/]\.php(/|$) {
145 fastcgi_split_path_info ^(.+?\.php)(/.*)$;
146 if (!-f $document_root$fastcgi_script_name) {
149 fastcgi_pass unix:/var/run/php5-fpm.sock;
150 fastcgi_index search.php;
151 include fastcgi.conf;
154 Restart the nginx and php5-fpm services and the website should now be available
155 at `http://localhost/`.
158 Now continue with [importing the database](Import-and-Update.md).
