*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 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 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 \
|
|
php-phpunit-PHPUnit
|
|
pip install --user --upgrade pip setuptools lettuce==0.2.18 six==1.9 \
|
|
haversine Shapely pytidylib
|
|
|
|
|
|
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
|
|
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/twain47/Nominatim.git
|
|
cd Nominatim
|
|
|
|
|
|
|
|
|
|
|
|
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).
