MapProxy install and quick start guide

1. Installing MapProxy and dependecies

Install python-is-pyhton3:

~$ sudo apt install python-is-python3

check it:

~$ python -V

Install MapProxy through pip

~$ sudo pip install MapProxy

Install VirtualEnv

~$ sudo apt install python3-virtualenv

Create a new virtual environment

~$ virtualenv --system-site-packages mapproxy

Activate virtual environment (optional?)

~$ source mapproxy/bin/activate

Install dependencies

~$ sudo apt-get install python3-pil python3-yaml libproj12

libproj12 -> libproj19??

optional packages:

~$ sudo apt-get install libgeos-dev python3-lxml libgdal-dev python3-shapely

2. Config

Create a configuration:

~$ mapproxy-util create -t base-config mymapproxy

Edit ~/mymapproxy/mapproxy.yaml:

don't forger to replace with your user name!

mapproxy.yaml:

services:
  demo:
  tms:
    use_grid_names: true
    # origin for /tiles service
    origin: 'nw'
  kml:
      use_grid_names: true
  wmts:

3. Start Test Server

~$ cd mymapproxy

...$ mapproxy-util serve-develop mapproxy.yaml

4. Access rights

mkdir /home/<user>/mymapproxy/cache_data/

chmod -R 777 /home/<user>/mapproxy/cache_data/

chmod -R 777 /home/<user>/mymapproxy/cache_data/

5. apache2 WSGI

Create role <user>

sudo -i -u postgres

psql -d <osm_db_name>

CREATE USER <user>;
GRANT ALL PRIVILEGES ON DATABASE "<osm_db_name>" to <user>;
GRANT ALL ON ALL TABLES IN SCHEMA public TO <user>;

Install mod-wsgi:

sudo apt install libapache2-mod-wsgi-py3

Create mapproxy config:

mapproxy-util create -t wsgi-app -f mapproxy.yaml config.py

Create apache2 config:

/etc/apache2/conf-enabled/mapproxy.conf:

# if not loaded elsewhere
LoadModule wsgi_module modules/mod_wsgi.so

WSGIScriptAlias / /home/<user>/mapproxy/config.py

WSGIDaemonProcess mapproxy user=<user> group=<user> processes=4 threads=8
WSGIProcessGroup mapproxy
# WSGIPythonHome should contain the bin and lib dir of your virtualenv
WSGIPythonHome /home/<user>/mapproxy/
WSGIApplicationGroup %{GLOBAL}

<Directory /home/<user>/mapproxy/>
  Order deny,allow
  Require all granted
#  Allow from all
</Directory>
