# *Note:* these installation instructions are also available in executable

# form for use with vagrant under `vagrant/Install-on-Centos-8.sh`.
|

#
|
|
# Installing the Required Software
|
|
# ================================
|
|
#
|
|
# These instructions expect that you have a freshly installed CentOS version 8.
|
|
# Make sure all packages are up-to-date by running:
|
|
#
|
|
sudo dnf update -y
|
|
|
|
# The standard CentOS repositories don't contain all the required packages,
|
|
# you need to enable the EPEL repository as well. For example for SELinux
|
|
# related redhat-hardened-cc1 package. To enable it on CentOS run:
|
|
|
|
sudo dnf install -y epel-release redhat-rpm-config
|
|
|
|
# EPEL contains Postgres 9.6 and 10, but not PostGIS. Postgres 9.4+/10/11/12
|
|
# and PostGIS 2.4/2.5/3.0 are availble from postgresql.org. Enable these
|
|
# repositories and make sure, the binaries can be found:
|
|
|
|
sudo dnf -qy module disable postgresql
|
|
sudo dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
|
|
export PATH=/usr/pgsql-12/bin:$PATH
|
|
|
|
# Now you can install all packages needed for Nominatim:
|
|
|
|
#DOCS: :::sh
|
|
sudo dnf --enablerepo=powertools install -y postgresql12-server \
|

# 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:
|
|
#
|
|
if [ "x$USERNAME" == "x" ]; then #DOCS:
|
|
export USERNAME=vagrant #DOCS: export USERNAME=nominatim
|
|
export USERHOME=/srv/nominatim
|
|
sudo mkdir -p /srv/nominatim #DOCS:
|
|
sudo chown vagrant /srv/nominatim #DOCS:
|
|
fi #DOCS:
|
|
#
|
|
# **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 $USERHOME
|
|
|
|
# Setting up PostgreSQL
|
|
# ---------------------
|
|
#
|
|
# CentOS does not automatically create a database cluster. Therefore, start
|
|
# with initializing the database:
|
|
|
|
if [ "x$NOSYSTEMD" == "xyes" ]; then #DOCS:
|
|
sudo -u postgres /usr/pgsql-12/bin/pg_ctl initdb -D /var/lib/pgsql/12/data #DOCS:
|
|
sudo mkdir /var/log/postgresql #DOCS:
|
|
sudo chown postgres. /var/log/postgresql #DOCS:
|
|
else #DOCS:
|
|
sudo /usr/pgsql-12/bin/postgresql-12-setup initdb
|
|
fi #DOCS:
|
|
#
|
|
# Next tune the postgresql configuration, which is located in
|
|
# `/var/lib/pgsql/12/data/postgresql.conf`. See section *Postgres Tuning* in
|
|
# [the installation page](../admin/Installation.md#postgresql-tuning)
|
|
# for the parameters to change.
|
|
#
|
|
# Now start the postgresql service after updating this config file:
|
|
|
|
if [ "x$NOSYSTEMD" == "xyes" ]; then #DOCS:
|
|
sudo -u postgres /usr/pgsql-12/bin/pg_ctl -D /var/lib/pgsql/12/data -l /var/log/postgresql/postgresql-12.log start #DOCS:
|
|
else #DOCS:
|
|
sudo systemctl enable postgresql-12
|
|
sudo systemctl restart postgresql-12
|
|
fi #DOCS:
|
|
|
|
#
|
|
# 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

# Building and Configuration
|

# Get the source code from Github and change into the source directory
|

|
|
fi #DOCS:
|
|
|
|

# Setting up the Apache Webserver
|
|
# -------------------------------
|
|
#
|
|
# The webserver should serve the php scripts from the website directory of your
|
|
# [project directory](../admin/Import.md#creating-the-project-directory).
|
|
# This directory needs to exist when the webserver is configured.
|
|
# Therefore set up a project directory and create the website directory:
|
|
#
|
|
mkdir $USERHOME/nominatim-project
|
|
mkdir $USERHOME/nominatim-project/website
|
|
#
|
|
# You need to create an alias to the website directory in your apache
|
|
# configuration. Add a separate nominatim configuration to your webserver:
|
|
|
|
#DOCS:```sh
|
|
sudo tee /etc/httpd/conf.d/nominatim.conf << EOFAPACHECONF
|

# 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
