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 20.04](../appendix/Install-on-Ubuntu-20.md)
8 * [Ubuntu 18.04](../appendix/Install-on-Ubuntu-18.md)
9 * [CentOS 8](../appendix/Install-on-Centos-8.md)
10 * [CentOS 7.2](../appendix/Install-on-Centos-7.md)
12 These OS-specific instructions can also be found in executable form
13 in the `vagrant/` directory.
15 Users have created instructions for other frameworks. We haven't tested those
16 and can't offer support.

48 For running continuous updates:
50 * [pyosmium](https://osmcode.org/pyosmium/) (with Python 3)
54 * [behave](http://pythonhosted.org/behave/)
55 * [nose](https://nose.readthedocs.io)
56 * [phpunit](https://phpunit.de) >= 7.3
60 A minimum of 2GB of RAM is required or installation will fail. For a full
61 planet import 64GB of RAM or more are strongly recommended. Do not report
62 out of memory problems if you have less than 64GB RAM.
64 For a full planet install you will need at least 800GB of hard disk space
65 (take into account that the OSM database is growing fast). SSD disks
66 will help considerably to speed up import and queries.
68 Even on a well configured machine the import of a full planet takes
69 at least 2 days. Without SSDs 7-8 days are more realistic.
71 ## Setup of the server
75 You might want to tune your PostgreSQL installation so that the later steps
76 make best use of your hardware. You should tune the following parameters in
77 your `postgresql.conf` file.
80 maintenance_work_mem = (10GB)
81 autovacuum_work_mem = 2GB
83 effective_cache_size = (24GB)
84 synchronous_commit = off
85 checkpoint_segments = 100 # only for postgresql <= 9.4
86 max_wal_size = 1GB # postgresql > 9.4
87 checkpoint_timeout = 10min
88 checkpoint_completion_target = 0.9
90 The numbers in brackets behind some parameters seem to work fine for
91 64GB RAM machine. Adjust to your setup. A higher number for `max_wal_size`
92 means that PostgreSQL needs to run checkpoints less often but it does require
93 the additional space on your disk.
95 Autovacuum must not be switched off because it ensures that the
96 tables are frequently analysed. If your machine has very little memory,
97 you might consider setting:
99 autovacuum_max_workers = 1
101 and even reduce `autovacuum_work_mem` further. This will reduce the amount
102 of memory that autovacuum takes away from the import process.
104 For the initial import, you should also set:
107 full_page_writes = off
109 Don't forget to reenable them after the initial import or you risk database
115 The `website/` directory in the build directory contains the configured
116 website. Include the directory into your webbrowser to serve php files
119 #### Configure for use with Apache
121 Make sure your Apache configuration contains the required permissions for the
122 directory and create an alias:
125 <Directory "/srv/nominatim/build/website">
126 Options FollowSymLinks MultiViews
127 AddType text/html .php
128 DirectoryIndex search.php
131 Alias /nominatim /srv/nominatim/build/website
134 `/srv/nominatim/build` should be replaced with the location of your
137 After making changes in the apache config you need to restart apache.
138 The website should now be available on http://localhost/nominatim.
140 #### Configure for use with Nginx
142 Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
144 By default php listens on a network socket. If you want it to listen to a
145 Unix socket instead, change the pool configuration (`pool.d/www.conf`) as
148 ; Comment out the tcp listener and add the unix socket
149 ;listen = 127.0.0.1:9000
150 listen = /var/run/php5-fpm.sock
152 ; Ensure that the daemon runs as the correct user
153 listen.owner = www-data
154 listen.group = www-data
157 Tell nginx that php files are special and to fastcgi_pass to the php-fpm
158 unix socket by adding the location definition to the default configuration.
161 root /srv/nominatim/build/website;
164 try_files $uri $uri/ @php;
168 fastcgi_param SCRIPT_FILENAME "$document_root$uri.php";
169 fastcgi_param PATH_TRANSLATED "$document_root$uri.php";
170 fastcgi_param QUERY_STRING $args;
171 fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
172 fastcgi_index index.php;
173 include fastcgi_params;
176 location ~ [^/]\.php(/|$) {
177 fastcgi_split_path_info ^(.+?\.php)(/.*)$;
178 if (!-f $document_root$fastcgi_script_name) {
181 fastcgi_pass unix:/var/run/php7.3-fpm.sock;
182 fastcgi_index search.php;
183 include fastcgi.conf;
187 Restart the nginx and php5-fpm services and the website should now be available
188 at `http://localhost/`.
191 Now continue with [importing the database](Import.md).
