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 * a webserver (apache or nginx are recommended)
50 For running continuous updates:
52 * [pyosmium](https://osmcode.org/pyosmium/) (with Python 3)
56 A minimum of 2GB of RAM is required or installation will fail. For a full
57 planet import 32GB of RAM or more are strongly recommended.
59 For a full planet install you will need at least 700GB of hard disk space
60 (take into account that the OSM database is growing fast). SSD disks
61 will help considerably to speed up import and queries.
63 On a 6-core machine with 32GB RAM and SSDs the import of a full planet takes
64 a bit more than 2 days. Without SSDs 7-8 days are more realistic.
67 ## Setup of the server
71 You might want to tune your PostgreSQL installation so that the later steps
72 make best use of your hardware. You should tune the following parameters in
73 your `postgresql.conf` file.
76 maintenance_work_mem (10GB)
78 effective_cache_size (24GB)
79 synchronous_commit = off
80 checkpoint_segments = 100 # only for postgresql <= 9.4
81 checkpoint_timeout = 10min
82 checkpoint_completion_target = 0.9
84 The numbers in brackets behind some parameters seem to work fine for
85 32GB RAM machine. Adjust to your setup.
87 For the initial import, you should also set:
90 full_page_writes = off
92 Don't forget to reenable them after the initial import or you risk database
93 corruption. Autovacuum must not be switched off because it ensures that the
94 tables are frequently analysed.
98 The `website/` directory in the build directory contains the configured
99 website. Include the directory into your webbrowser to serve php files
102 #### Configure for use with Apache
104 Make sure your Apache configuration contains the required permissions for the
105 directory and create an alias:
107 <Directory "/srv/nominatim/build/website">
108 Options FollowSymLinks MultiViews
109 AddType text/html .php
110 DirectoryIndex search.php
113 Alias /nominatim /srv/nominatim/build/website
115 `/srv/nominatim/build` should be replaced with the location of your
118 After making changes in the apache config you need to restart apache.
119 The website should now be available on http://localhost/nominatim.
121 #### Configure for use with Nginx
123 Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
125 By default php listens on a network socket. If you want it to listen to a
126 Unix socket instead, change the pool configuration (`pool.d/www.conf`) as
129 ; Comment out the tcp listener and add the unix socket
130 ;listen = 127.0.0.1:9000
131 listen = /var/run/php5-fpm.sock
133 ; Ensure that the daemon runs as the correct user
134 listen.owner = www-data
135 listen.group = www-data
138 Tell nginx that php files are special and to fastcgi_pass to the php-fpm
139 unix socket by adding the location definition to the default configuration.
141 root /srv/nominatim/build/website;
142 index search.php index.html;
143 location ~ [^/]\.php(/|$) {
144 fastcgi_split_path_info ^(.+?\.php)(/.*)$;
145 if (!-f $document_root$fastcgi_script_name) {
148 fastcgi_pass unix:/var/run/php5-fpm.sock;
149 fastcgi_index search.php;
150 include fastcgi.conf;
153 Restart the nginx and php5-fpm services and the website should now be available
154 at `http://localhost/`.
157 Now continue with [importing the database](Import-and-Update.md).
