3 # *Note:* these installation instructions are also available in executable
4 # form for use with vagrant under `vagrant/Install-on-Centos-7.sh`.
6 # Installing the Required Software
7 # ================================
9 # These instructions expect that you have a freshly installed CentOS version 7.
10 # Make sure all packages are up-to-date by running:
14 # The standard CentOS repositories don't contain all the required packages,
15 # you need to enable the EPEL repository as well. To enable it on CentOS,
16 # install the epel-release RPM by running:
18 sudo yum install -y epel-release
20 # More repositories for postgresql 11 (CentOS default 'postgresql' is 9.2), postgis
21 # and llvm-toolset (https://github.com/theory/pg-semver/issues/35)
23 sudo yum install -y https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
24 sudo yum install -y centos-release-scl-rh
26 # More repositories for PHP 7 (default is PHP 5.4)
28 sudo yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm
29 sudo yum-config-manager --enable remi-php72
32 # Now you can install all packages needed for Nominatim:
36 sudo yum install -y postgresql11-server postgresql11-contrib postgresql11-devel \
37 postgis25_11 postgis25_11-utils \
38 wget git cmake make gcc gcc-c++ libtool policycoreutils-python \
39 devtoolset-7 llvm-toolset-7 \
40 php-pgsql php php-intl libpqxx-devel \
41 proj-epsg bzip2-devel proj-devel boost-devel \
42 python3-pip python3-setuptools python3-devel \
43 expat-devel zlib-devel
45 pip3 install --user psycopg2 python-dotenv psutil
49 # System Configuration
50 # ====================
52 # The following steps are meant to configure a fresh CentOS installation
53 # for use with Nominatim. You may skip some of the steps if you have your
54 # OS already configured.
56 # Creating Dedicated User Accounts
57 # --------------------------------
59 # Nominatim will run as a global service on your machine. It is therefore
60 # best to install it under its own separate user account. In the following
61 # we assume this user is called nominatim and the installation will be in
62 # /srv/nominatim. To create the user and directory run:
64 sudo mkdir -p /srv/nominatim #DOCS: sudo useradd -d /srv/nominatim -s /bin/bash -m nominatim
65 sudo chown vagrant /srv/nominatim #DOCS:
67 # You may find a more suitable location if you wish.
69 # To be able to copy and paste instructions from this manual, export
70 # user name and home directory now like this:
72 export USERNAME=vagrant #DOCS: export USERNAME=nominatim
73 export USERHOME=/srv/nominatim
75 # **Never, ever run the installation as a root user.** You have been warned.
77 # Make sure that system servers can read from the home directory:
81 # Setting up PostgreSQL
82 # ---------------------
84 # CentOS does not automatically create a database cluster. Therefore, start
85 # with initializing the database, then enable the server to start at boot:
87 sudo /usr/pgsql-11/bin/postgresql-11-setup initdb
88 sudo systemctl enable postgresql-11
91 # Next tune the postgresql configuration, which is located in
92 # `/var/lib/pgsql/data/postgresql.conf`. See section *Postgres Tuning* in
93 # [the installation page](../admin/Installation.md#postgresql-tuning)
94 # for the parameters to change.
96 # Now start the postgresql service after updating this config file.
98 sudo systemctl restart postgresql-11
101 # Finally, we need to add two postgres users: one for the user that does
102 # the import and another for the webserver which should access the database
106 sudo -u postgres createuser -s $USERNAME
107 sudo -u postgres createuser apache
110 # Installing Nominatim
111 # ====================
113 # Building and Configuration
114 # --------------------------
116 # Get the source code from Github and change into the source directory
118 if [ "x$1" == "xyes" ]; then #DOCS: :::sh
120 git clone --recursive git://github.com/openstreetmap/Nominatim.git
123 cd $USERHOME/Nominatim #DOCS:
126 # When installing the latest source from github, you also need to
127 # download the country grid:
129 if [ ! -f data/country_osm_grid.sql.gz ]; then #DOCS: :::sh
130 wget --no-verbose -O data/country_osm_grid.sql.gz https://www.nominatim.org/data/country_grid.sql.gz
133 # The code must be built in a separate directory. Create this directory,
134 # then configure and build Nominatim in there:
137 mkdir $USERHOME/build
139 cmake $USERHOME/Nominatim
144 # Setting up the Apache Webserver
145 # -------------------------------
147 # The webserver should serve the php scripts from the website directory of your
148 # [project directory](../admin/import.md#creating-the-project-directory).
149 # Therefore set up a project directory and populate the website directory:
151 mkdir $USERHOME/nominatim-project
152 cd $USERHOME/nominatim-project
153 nominatim refresh --website
155 # You need to create an alias to the website directory in your apache
156 # configuration. Add a separate nominatim configuration to your webserver:
159 sudo tee /etc/httpd/conf.d/nominatim.conf << EOFAPACHECONF
160 <Directory "$USERHOME/nominatim-project/website">
161 Options FollowSymLinks MultiViews
162 AddType text/html .php
163 DirectoryIndex search.php
167 Alias /nominatim $USERHOME/nominatim-project/website
171 sudo sed -i 's:#.*::' /etc/httpd/conf.d/nominatim.conf #DOCS:
177 sudo systemctl enable httpd
178 sudo systemctl restart httpd
181 # Adding SELinux Security Settings
182 # --------------------------------
184 # It is a good idea to leave SELinux enabled and enforcing, particularly
185 # with a web server accessible from the Internet. At a minimum the
186 # following SELinux labeling should be done for Nominatim:
188 sudo semanage fcontext -a -t httpd_sys_content_t "/usr/local/nominatim/lib/lib-php(/.*)?"
189 sudo semanage fcontext -a -t httpd_sys_content_t "$USERHOME/nominatim-project/website(/.*)?"
190 sudo semanage fcontext -a -t lib_t "$USERHOME/nominatim-project/module/nominatim.so"
191 sudo restorecon -R -v /usr/local/lib/nominatim
192 sudo restorecon -R -v $USERHOME/nominatim-project
195 # You need to create a minimal configuration file that tells nominatim
196 # the name of your webserver user:
199 echo NOMINATIM_DATABASE_WEBUSER="apache" | tee .env
203 # Nominatim is now ready to use. Continue with
204 # [importing a database from OSM data](../admin/Import.md).
