*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
[importing a database from OSM data](Import-and-Update.md).

Database Migrations
===================
This page describes database migrations necessary to update existing databases
to newer versions of Nominatim.
SQL statements should be executed from the postgres commandline. Execute
`psql nominiatim` to enter command line mode.
3.0.0
-----
### Postcode Table
A new separate table for artificially computed postcode centroids was introduced.
Migration to the new format is possible but **not recommended**.
* create postcode table and indexes, running the following SQL statements:
CREATE TABLE location_postcode
(place_id BIGINT, parent_place_id BIGINT, rank_search SMALLINT,
rank_address SMALLINT, indexed_status SMALLINT, indexed_date TIMESTAMP,
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;

Database Migrations
===================
This page describes database migrations necessary to update existing databases
to newer versions of Nominatim.
SQL statements should be executed from the postgres commandline. Execute
`psql nominiatim` to enter command line mode.
# 3.0.0 -> 3.1.0
### Postcode Table
A new separate table for artificially computed postcode centroids was introduced.
Migration to the new format is possible but **not recommended**.
Create postcode table and indexes, running the following SQL statements:
```sql
CREATE TABLE location_postcode
(place_id BIGINT, parent_place_id BIGINT, rank_search SMALLINT,
rank_address SMALLINT, indexed_status SMALLINT, indexed_date TIMESTAMP,
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:
```sql
ALTER TABLE location_area ADD COLUMN postcode TEXT;
```
Then reimport the functions:
```sh
./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
```
Create appropriate triggers with SQL:
```sql
CREATE TRIGGER location_postcode_before_update BEFORE UPDATE ON location_postcode
FOR EACH ROW EXECUTE PROCEDURE postcode_update();
```
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;
```
