[OpenLayers] OpenStreetMap Nominatim Service 安裝

Nominatim 能將經緯度轉換為地址，亦能將地址轉換為經緯度。
官方提供完整的安裝說明，網路上也有 docker image 能使用。以下使用 Ubuntu 16.04 來安裝，postgreSQL 版本是 9.5。

使用 apt-get 來安裝

sudo apt-get install -y build-essential cmake g++ libboost-dev libboost-system-dev \
                        libboost-filesystem-dev libexpat1-dev zlib1g-dev libxml2-dev\
                        libbz2-dev libpq-dev libproj-dev \
                        postgresql-server-dev-9.5 postgresql-9.5-postgis-2.2 \
                        postgresql-contrib-9.5 \
                        apache2 php php-pgsql libapache2-mod-php php-pear php-db \
                        php-intl git

建立 user，並給予權限。

sudo useradd -d /srv/nominatim -s /bin/bash -m nominatim

export USERNAME=nominatim 
export USERHOME=/srv/nominatim
chmod a+x $USERHOME

## 建立 postgres 帳號
sudo -u postgres createuser -s $USERNAME 
sudo -u postgres createuser www-data

新增 nominatim.conf 檔，內容如下。

sudo tee /etc/apache2/conf-available/nominatim.conf << EOFAPACHECONF 
<directory build="" ominatim-3.2.0="" website=""> 
  Options FollowSymLinks MultiViews 
  AddType text/html .php 
  DirectoryIndex search.php 
  Require all granted 
</directory> 
Alias /nominatim $USERHOME/Nominatim-3.2.0/build/website 
EOFAPACHECONF

重啟服務

sudo a2enconf nominatim 
sudo service apache2 restart
