How to get WRF4G
The latest official version can get it by direct download WRF4G.tar.gz. Before you get it, you have to check the WRF4G requirements:
- x86_64 Linux
[user@localhost ~]$ uname -p x86_64
- Python, version >= 2.4 and < 3.0
[user@localhost ~]$ python -V Python 2.7.3
See the installation guide for moreover information.
Quick deploy guide
Deploy WRF4G
Download and unpack the distribution file into the deployment directory (e.g. $HOME directory).
[user@localhost ~]$ cd [user@localhost ~]$ wget http://www.meteo.unican.es/work/WRF4G.tar.gz [user@localhost ~]$ tar xzvf WRF4G.tar.gz
Setup the WRF4G environment.
[user@localhost ~]$ export PATH=$HOME/WRF4G/bin:$PATH
In order to avoid typing the export command every time you open a terminal, you should copy it into $HOME/.bashrc.
[user@localhost ~]$ echo "export PATH=$HOME/WRF4G/bin:$PATH" >> $HOME/.bashrc
Verifying
You can verify if WRF4G has been deployed properly by running the following command:
[user@localhost ~]$ wrf4g_framework start Starting DRM4G (GridWay) .... OK Starting WRF4G_DB (MySQL) ... OK
If the answers are not satisfactory ("OK"), you should check out the log files:
- $HOME/WRF4G/opt/drm4g_gridway/var/gwd.log for DRM4G (GridWay)
- $HOME/WRF4G/var/mysql.log for WRF4G_DB (MySQL).
How to configure computing resources
By default, WRF4G is going to use the local machine as FORK system
