2 *Note:* these installation instructions are also available in executable
3 form for use with vagrant under vagrant/install-on-centos-7.sh.
5 Installing the Required Software
6 ================================
8 These instructions expect that you have a freshly installed CentOS version 7.
9 Make sure all packages are are up-to-date by running:
13 The standard CentOS repositories don't contain all the required packages,
14 you need to enable the EPEL repository as well. To enable it on CentOS,
15 install the epel-release RPM by running:
17 sudo yum install -y epel-release
19 Now you can install all packages needed for Nominatim:
21 sudo yum install -y postgresql-server postgresql-contrib postgresql-devel postgis postgis-utils \
22 git cmake make gcc gcc-c++ libtool policycoreutils-python \
23 php-pgsql php php-pear php-pear-DB libpqxx-devel proj-epsg \
24 bzip2-devel proj-devel geos-devel libxml2-devel boost-devel expat-devel zlib-devel
26 If you want to run the test suite, you need to install the following
29 sudo yum install -y python-pip python-Levenshtein python-psycopg2 \
31 pip install --user --upgrade pip setuptools lettuce==0.2.18 six==1.9 \
32 haversine Shapely pytidylib
38 The following steps are meant to configure a fresh CentOS installation
39 for use with Nominatim. You may skip some of the steps if you have your
40 OS already configured.
42 Creating Dedicated User Accounts
43 --------------------------------
45 Nominatim will run as a global service on your machine. It is therefore
46 best to install it under its own separate user account. In the following
47 we assume this user is called nominatim and the installation will be in
48 /srv/nominatim. To create the user and directory run:
50 sudo useradd -d /srv/nominatim -s /bin/bash -m nominatim
52 You may find a more suitable location if you wish.
54 To be able to copy and paste instructions from this manual, export
55 user name and home directory now like this:
57 export USERNAME=nominatim
58 export USERHOME=/srv/nominatim
60 **Never, ever run the installation as a root user.** You have been warned.
62 Make sure that system servers can read from the home directory:
69 CentOS does not automatically create a database cluster. Therefore, start
70 with initializing the database, then enable the server to start at boot:
72 sudo postgresql-setup initdb
73 sudo systemctl enable postgresql
76 Next tune the postgresql configuration, which is located in
77 `/var/lib/pgsql/data/postgresql.conf`. See section *Postgres Tuning* in
78 [the installation page](Installation.md) for the parameters to change.
80 Now start the postgresql service after updating this config file.
82 sudo systemctl restart postgresql
85 Finally, we need to add two postgres users: one for the user that does
86 the import and another for the webserver ro access the database:
89 sudo -u postgres createuser -s $USERNAME
90 sudo -u postgres createuser apache
93 Setting up the Apache Webserver
94 -------------------------------
96 You need to create an alias to the website directory in your apache
97 configuration. Add a separate nominatim configuration to your webserver:
100 sudo tee /etc/httpd/conf.d/nominatim.conf << EOFAPACHECONF
101 <Directory "$USERHOME/Nominatim/build/website">
102 Options FollowSymLinks MultiViews
103 AddType text/html .php
107 Alias /nominatim $USERHOME/Nominatim/build/website
117 sudo systemctl restart httpd
120 Adding SELinux Security Settings
121 --------------------------------
123 It is a good idea to leave SELinux enabled and enforcing, particularly
124 with a web server accessible from the Internet. At a minimum the
125 following SELinux labeling should be done for Nominatim:
127 sudo semanage fcontext -a -t httpd_sys_content_t "$USERHOME/Nominatim/(website|lib|settings)(/.*)?"
128 sudo semanage fcontext -a -t lib_t "$USERHOME/Nominatim/module/nominatim.so"
129 sudo restorecon -R -v $USERHOME/Nominatim
135 Building and Configuration
136 --------------------------
138 Get the source code from Github and change into the source directory
143 git clone --recursive git://github.com/twain47/Nominatim.git
150 The code is built in a special directory. Create this directory,
151 then configure and build Nominatim in there:
155 cmake $USERHOME/Nominatim
158 You need to create a minimal configuration file that tells nominatim
159 the name of your webserver user and the URL of the website:
162 tee settings/local.php << EOF
164 @define('CONST_Database_Web_User', 'apache');
165 @define('CONST_Website_BaseURL', '/nominatim/');
170 Nominatim is now ready to use. Continue with
171 [importing a database from OSM data](Import_and_update.md).
