*Note:* these installation instructions are also available in executable
form for use with vagrant under `vagrant/Install-on-Centos-7.sh`.
Installing the Required Software
================================
These instructions expect that you have a freshly installed CentOS version 7.
Make sure all packages are up-to-date by running:
sudo yum update -y
The standard CentOS repositories don't contain all the required packages,
you need to enable the EPEL repository as well. To enable it on CentOS,
install the epel-release RPM by running:
sudo yum install -y epel-release
Now you can install all packages needed for Nominatim:
sudo yum install -y postgresql-server postgresql-contrib postgresql-devel postgis postgis-utils \
git cmake make gcc gcc-c++ libtool policycoreutils-python \
php-pgsql php php-pear php-pear-DB php-intl libpqxx-devel proj-epsg \
bzip2-devel proj-devel geos-devel libxml2-devel boost-devel expat-devel zlib-devel
If you want to run the test suite, you need to install the following
additional packages:
sudo yum install -y python-pip python-Levenshtein python-psycopg2 \
python-numpy php-phpunit-PHPUnit
pip install --user --upgrade pip setuptools lettuce==0.2.18 six==1.9 \
haversine Shapely pytidylib
sudo pear install PHP_CodeSniffer
System Configuration
====================
The following steps are meant to configure a fresh CentOS installation
for use with Nominatim. You may skip some of the steps if you have your
OS already configured.
Creating Dedicated User Accounts
--------------------------------
Nominatim will run as a global service on your machine. It is therefore
best to install it under its own separate user account. In the following
we assume this user is called nominatim and the installation will be in
/srv/nominatim. To create the user and directory run:
sudo useradd -d /srv/nominatim -s /bin/bash -m nominatim
You may find a more suitable location if you wish.
To be able to copy and paste instructions from this manual, export
user name and home directory now like this:
export USERNAME=nominatim
export USERHOME=/srv/nominatim
**Never, ever run the installation as a root user.** You have been warned.
Make sure that system servers can read from the home directory:
chmod a+x $USERHOME
Setting up PostgreSQL
---------------------
CentOS does not automatically create a database cluster. Therefore, start
with initializing the database, then enable the server to start at boot:
sudo postgresql-setup initdb
sudo systemctl enable postgresql
Next tune the postgresql configuration, which is located in
`/var/lib/pgsql/data/postgresql.conf`. See section *Postgres Tuning* in
[the installation page](Installation.md) for the parameters to change.
Now start the postgresql service after updating this config file.
sudo systemctl restart postgresql
Finally, we need to add two postgres users: one for the user that does
the import and another for the webserver which should access the database
only for reading:
sudo -u postgres createuser -s $USERNAME
sudo -u postgres createuser apache
Setting up the Apache Webserver
-------------------------------
You need to create an alias to the website directory in your apache
configuration. Add a separate nominatim configuration to your webserver:
```
sudo tee /etc/httpd/conf.d/nominatim.conf << EOFAPACHECONF
<Directory "$USERHOME/Nominatim/build/website">
Options FollowSymLinks MultiViews
AddType text/html .php
DirectoryIndex search.php
Require all granted
</Directory>
Alias /nominatim $USERHOME/Nominatim/build/website
EOFAPACHECONF
```
Then reload apache
sudo systemctl restart httpd
Adding SELinux Security Settings
--------------------------------
It is a good idea to leave SELinux enabled and enforcing, particularly
with a web server accessible from the Internet. At a minimum the
following SELinux labeling should be done for Nominatim:
sudo semanage fcontext -a -t httpd_sys_content_t "$USERHOME/Nominatim/(website|lib|settings)(/.*)?"
sudo semanage fcontext -a -t lib_t "$USERHOME/Nominatim/module/nominatim.so"
sudo restorecon -R -v $USERHOME/Nominatim
Installing Nominatim
====================
Building and Configuration
--------------------------
Get the source code from Github and change into the source directory
cd $USERHOME
git clone --recursive git://github.com/openstreetmap/Nominatim.git
cd Nominatim
When installing the latest source from github, you also need to
download the country grid:
wget -O data/country_osm_grid.sql.gz https://www.nominatim.org/data/country_grid.sql.gz
The code must be built in a separate directory. Create this directory,
then configure and build Nominatim in there:
mkdir build
cd build
cmake $USERHOME/Nominatim
make
You need to create a minimal configuration file that tells nominatim
the name of your webserver user and the URL of the website:
```
tee settings/local.php << EOF
<?php
@define('CONST_Database_Web_User', 'apache');
@define('CONST_Website_BaseURL', '/nominatim/');
EOF
```
Nominatim is now ready to use. Continue with

country_code varchar(2), postcode TEXT,
geometry GEOMETRY(Geometry, 4326));
CREATE INDEX idx_postcode_geometry ON location_postcode USING GIST (geometry);
CREATE UNIQUE INDEX idx_postcode_id ON location_postcode USING BTREE (place_id);
CREATE INDEX idx_postcode_postcode ON location_postcode USING BTREE (postcode);
GRANT SELECT ON location_postcode TO "www-data";
* add postcode column to location_area tables with SQL statement:
ALTER TABLE location_area ADD COLUMN postcode TEXT;
* reimport functions
./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
* create appropriate triggers with SQL:
CREATE TRIGGER location_postcode_before_update BEFORE UPDATE ON location_postcode
FOR EACH ROW EXECUTE PROCEDURE postcode_update();
* populate postcode table (will take a while):
./utils/setup.php --calculate-postcodes --index --index-noanalyse
This will create a working database. You may also delete the old artificial
postcodes now. Note that this may be expensive and is not absolutely necessary.
The following SQL statement will remove them:
DELETE FROM place_addressline a USING placex p
WHERE a.address_place_id = p.place_id and p.osm_type = 'P';
ALTER TABLE placex DISABLE TRIGGER USER;
DELETE FROM placex WHERE osm_type = 'P';
ALTER TABLE placex ENABLE TRIGGER USER;

The following instructions explain how to create a Nominatim database

software itself, if not return to the [installation page](Installation.md).
Configuration setup in settings/local.php

wget https://www.nominatim.org/data/gb_postcode_data.sql.gz
Initial import of the data
--------------------------
# Initial import of the data
**Important:** first try the import with a small excerpt, for example from
[Geofabrik](https://download.geofabrik.de).
Download the data to import and load the data with the following command:
./utils/setup.php --osm-file <your data file> --all [--osm2pgsql-cache 28000] 2>&1 | tee setup.log
```sh
./utils/setup.php --osm-file <data file> --all [--osm2pgsql-cache 28000] 2>&1 | tee setup.log
```
The `--osm2pgsql-cache` parameter is optional but strongly recommended for
planet imports. It sets the node cache size for the osm2pgsql import part
(see `-C` parameter in osm2pgsql help). 28GB are recommended for a full planet
import, for excerpts you can use less. Adapt to your available RAM to
avoid swapping, never give more than 2/3 of RAM to osm2pgsql.
(see `-C` parameter in osm2pgsql help). As a rule of thumb, this should be
about the same size as the file you are importing but never more than
2/3 of RAM available. If your machine starts swapping reduce the size.
Computing word frequency for search terms can improve the performance of
forward geocoding in particular under high load as it helps Postgres' query
planner to make the right decisions. To recompute word counts run:
./utils/update.php --recompute-word-counts
```sh
./utils/update.php --recompute-word-counts
```
This will take a couple of hours for a full planet installation. You can
also defer that step to a later point in time when you realise that
performance becomes an issue. Just make sure that updates are stopped before
running this function.
Loading additional datasets
---------------------------
The following commands will create additional entries for POI searches:
If you want to be able to search for places by their type through
[special key phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases)

psql -d nominatim -f specialphrases.sql
Note that this command downloads the phrases from the wiki link above.
Installing Tiger housenumber data for the US

* CentOS: `sudo yum install gdal-python unzip`
2. Get the TIGER 2015 data. You will need the EDGES files
2. Get preprocessed TIGER 2015 data and unpack it into the
data directory in your Nominatim sources:
cd Nominatim/data
wget https://nominatim.org/data/tiger2017-nominatim-preprocessed.tar.gz
tar xf tiger2017-nominatim-preprocessed.tar.gz
3. Import the data into your Nominatim database:

4. Enable use of the Tiger data in your `settings/local.php` by adding:
@define('CONST_Use_US_Tiger_Data', true);
5. Apply the new settings:
```sh
./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
```
The entire US adds about 10GB to your database.
You can also process the data from the original TIGER data to create the
SQL files, Nominatim needs for the import:
1. Get the TIGER 2017 data. You will need the EDGES files
(3,234 zip files, 11GB total). Choose one of the two sources:

mirror.
3. Convert the data into SQL statements (stored in data/tiger):
2. Convert the data into SQL statements:
./utils/imports.php --parse-tiger <tiger edge data directory>
4. Import the data into your Nominatim database:
Be warned that this can take quite a long time. After this process is finished,

Finally populate the postcode table (will take a while):
```sh
./utils/setup.php --calculate-postcodes --index --index-noanalyse
```
This will create a working database. You may also delete the old artificial
postcodes now. Note that this may be expensive and is not absolutely necessary.
The following SQL statement will remove them:
```sql
DELETE FROM place_addressline a USING placex p
WHERE a.address_place_id = p.place_id and p.osm_type = 'P';
ALTER TABLE placex DISABLE TRIGGER USER;
DELETE FROM placex WHERE osm_type = 'P';
ALTER TABLE placex ENABLE TRIGGER USER;
```
