    24When getting ready to run experiments in GENI, it is always a good idea to automate the setup of your experiment.

    141 === Reserver a PlanetLab node ===
    142 In order to install a web server in a PlanetLab node, it is better if you create a separate slice just for the web server and use the [attachment:plc-bbn-onenode.rspec attached rspec] to reserve a PlanetLab node. You can use either Omni or Flack to do this. If you are using Flack, then you can see [ this video] about how to create a slice with an existing rspec using Flack. While you follow the video make sure you also choose the `plc` manager so that you can reserver PlanetLab nodes.
    144 === Install and start a Web Server ===
    145 Be patient, it might take up to 30-40 minutes for you sliver to be ready. Once your sliver is created you can login to your node. If you don't know how to login to your node you can follow [wiki:HowTo/LoginToNodes these instructions].
    147 After you login :
    148   * install the apache server by running :
    149    {{{
    150 sudo yum install -y httpd
    151 }}}
    152    * modify the default port by running the following commande where <NEW_PORT> is the port you want to use:
    153 {{{
    154 sudo sed 's/^Listen 80$/Listen <NEW_PORT>/' /etc/httpd/conf/httpd.conf > httpd.conf ; sudo mv httpd.conf /etc/httpd/conf/httpd.conf
    155 }}}
    156    * start the web server :
    157 {{{
    158 sudo /sbin/service httpd start
    159 }}}
    160        If you get an error someone else might be using the port you used, change it again by using the following command where <OLD_PORT> is the port you used in the previous command:
    161 {{{
    162 sudo sed 's/^Listen <OLD_PORT>$/Listen <NEW_PORT>/' /etc/httpd/conf/httpd.conf > httpd.conf ; sudo mv httpd.conf /etc/httpd/conf/httpd.conf
    163 }}}
    165 In order to test that your webserver is up and running open a web brower and point it at '''!<NEW_PORT>/''' you should get the apache welcome page.
    167 === Upload files to your webserver ===
    168 In order to make files publicly available in your server do these two simple steps :
    169   * transfer the file to the PlanetLab node. You can use scp to do this e.g.:
    170   {{{
    171  scp -i /home/nriga/.ssh/geni_key install-mpich.tar.gz
    172 }}}
    173   * login to your node and move the file to '/var/www/html', e.g.
    174     {{{
    175  sudo mv install-mpich.tar.gz /var/www/html/
    176 }}}
