Pemasangan GeoDjango¶

Variabel lingkungan LD_LIBRARY_PATH¶

A user may set this environment variable to customize the library paths they want to use. The typical library directory for software built from source is /usr/local/lib. Thus, /usr/local/lib needs to be included in the LD_LIBRARY_PATH variable. For example, the user could place the following in their bash profile:

export LD_LIBRARY_PATH=/usr/local/lib

Menyetel jalur pustakan sistem¶

On GNU/Linux systems, there is typically a file in /etc/ld.so.conf, which may include additional paths from files in another directory, such as /etc/ld.so.conf.d. As the root user, add the custom library path (like /usr/local/lib) on a new line in ld.so.conf. This is one example of how to do so:

$ sudo echo /usr/local/lib >> /etc/ld.so.conf
$ sudo ldconfig

For OpenSolaris users, the system library path may be modified using the crle utility. Run crle with no options to see the current configuration and use crle -l to set with the new library path. Be very careful when modifying the system library path:

# crle -l $OLD_PATH:/usr/local/lib

Pasang binutils¶

GeoDjango uses the find_library function (from the ctypes.util Python module) to discover libraries. The find_library routine uses a program called objdump (part of the binutils package) to verify a shared library on GNU/Linux systems. Thus, if binutils is not installed on your Linux system then Python's ctypes may not be able to find your library even if your library path is set correctly and geospatial libraries were built perfectly.

The binutils package may be installed on Debian and Ubuntu systems using the following command:

$ sudo apt-get install binutils

Mirip, pada sistem Red Hat dan CentOS:

$ sudo yum install binutils

Python¶

Although macOS comes with Python installed, users can use `framework installers`__ provided by the Python Software Foundation. An advantage to using the installer is that macOS's Python will remain "pristine" for internal operating system use.

export PATH=/Library/Frameworks/Python.framework/Versions/Current/bin:$PATH

Postgres.app¶

Postgres.app is a standalone PostgreSQL server that includes the PostGIS extension. You will also need to install gdal and libgeoip with Homebrew.

Setelah memasang Postgres.app, tambah berikut ke .bash_profile anda sehingga anda dapat menjalankan progam paket dari baris-perintah. Ganti X.Y dengan versi PostgreSQL di Postgres.app anda pasang:

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/X.Y/bin

Anda dapat memeriksa jalur disetel dengan benar dengan mengetik which psql pada terminal prompt.

Homebrew¶

`Homebrew`__ provides "recipes" for building binaries and packages from source. It provides recipes for the GeoDjango prerequisites on Macintosh computers running macOS. Because Homebrew still builds the software from source, Xcode is required.

Ringkasan:

$ brew install postgresql
$ brew install postgis
$ brew install gdal
$ brew install libgeoip

Paket KyngChaos¶

William Kyngesburye provides a number of `geospatial library binary packages`__ that make it simple to get GeoDjango installed on macOS without compiling them from source. However, Xcode is still necessary for compiling the Python database adapters psycopg2 (for PostGIS).

Unduh paket kerangka untuk:

• UnixImageIO
• PROJ
• GEOS
• SQLite3 (menyertakan pustaka SpatiaLite)
• GDAL

Memasang paket-paket di urutan mereka terdaftar diatas, seperti paket GDAL dan SQLite membutuhkan paket-paket terdaftar sebelum mereka.

Setelah itu, anda dapat juga memasang paket biner KyngChaos untuk PostgreSQL and PostGIS`__.

After installing the binary packages, you'll want to add the following to your .profile to be able to run the package programs from the command-line:

export PATH=/Library/Frameworks/UnixImageIO.framework/Programs:$PATH
export PATH=/Library/Frameworks/PROJ.framework/Programs:$PATH
export PATH=/Library/Frameworks/GEOS.framework/Programs:$PATH
export PATH=/Library/Frameworks/SQLite3.framework/Programs:$PATH
export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH
export PATH=/usr/local/pgsql/bin:$PATH

$ pip install psycopg2

MacPorts¶

`MacPorts`__ may be used to install GeoDjango prerequisites on computers running macOS. Because MacPorts still builds the software from source, Xcode is required.

Ringkasan:

$ sudo port install postgresql93-server
$ sudo port install geos
$ sudo port install proj
$ sudo port install postgis
$ sudo port install gdal +geos
$ sudo port install libgeoip

export PATH=/opt/local/bin:/opt/local/lib/postgresql93/bin

export DYLD_FALLBACK_LIBRARY_PATH=/opt/local/lib:/opt/local/lib/postgresql93

Python¶

Install Python.

PostgreSQL¶

Pertama, unduh `PostgreSQL 9.x installer`__ terakhir dari situs jaringan `EnterpriseDB`__. Setelah mengunduh, cukup jalankan pemasang, ikuti arahan layar, dan jaga pilihan awal kecuali kalau anda mengetahui konsekuensi merubah mereka.

Ketika pemasang lengkap, dia akan menanyakan untuk meluncurkan Application Stack Builder (ASB) pada keluar -- jaga ini tercentang, seperti dia diperlukan untuk memasang install PostGIS.

PostGIS¶

From within the Application Stack Builder (to run outside of the installer, Start ‣ Programs ‣ PostgreSQL 9.x), select PostgreSQL Database Server 9.x on port 5432 from the drop down menu. Next, expand the Categories ‣ Spatial Extensions menu tree and select PostGIS X.Y for PostgreSQL 9.x.

After clicking next, you will be prompted to select your mirror, PostGIS will be downloaded, and the PostGIS installer will begin. Select only the default options during install (e.g., do not uncheck the option to create a default PostGIS database).

psycopg2¶

The psycopg2 Python module provides the interface between Python and the PostgreSQL database. Download the latest `Windows installer`__ for your version of Python and PostgreSQL and run using the default settings. [2]

OSGeo4W¶

The OSGeo4W installer makes it simple to install the PROJ.4, GDAL, and GEOS libraries required by GeoDjango. First, download the OSGeo4W installer, and run it. Select Express Web-GIS Install and click next. In the 'Select Packages' list, ensure that GDAL is selected; MapServer and Apache are also enabled by default, but are not required by GeoDjango and may be unchecked safely. After clicking next, the packages will be automatically downloaded and installed, after which you may exit the installer.

Merubah lingkungan Windows¶

In order to use GeoDjango, you will need to add your Python and OSGeo4W directories to your Windows system Path, as well as create GDAL_DATA and PROJ_LIB environment variables. The following set of commands, executable with cmd.exe, will set this up:

set OSGEO4W_ROOT=C:\OSGeo4W
set PYTHON_ROOT=C:\Python3X
set GDAL_DATA=%OSGEO4W_ROOT%\share\gdal
set PROJ_LIB=%OSGEO4W_ROOT%\share\proj
set PATH=%PATH%;%PYTHON_ROOT%;%OSGEO4W_ROOT%\bin
reg ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v Path /t REG_EXPAND_SZ /f /d "%PATH%"
reg ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v GDAL_DATA /t REG_EXPAND_SZ /f /d "%GDAL_DATA%"
reg ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PROJ_LIB /t REG_EXPAND_SZ /f /d "%PROJ_LIB%"

Pasang Django dan setel basisdata¶

Akhirnya, pasang Django di sistem anda.
