The current init.d script (/root/cerebro/bin/cerebro.init) fails to stop Cerebro because some of the commands in /etc/rc.d/init.d/functions cannot handle the full string "cerebro -p -i msh0 &". The following is a quick fix for this problem: |

Installing Cerebro
In a terminal:
su - yum -y remove cerebro yum -y install git python-setuptools-devel.noarch git clone git://dev.laptop.org/projects/cerebro cd cerebro ./install.sh
Reboot.
trackclient.py
- cer = os.popen('pidof -x cerebro').read()
- cerui = os.popen('pidof -x cerebroui.olpc').read()
+ cer = os.popen('pidof -x cerebro').read().strip()
+ cerui = os.popen('pidof -x cerebroui').read().strip()
Notes
The Cerebro package in the latest Joyride builds (joyride-2130 or later) is largely equivalent to what you get by manually installing Cerebro from the git repository.
Version of your installed Cerebro package: "yum info cerebro"
Version in git: in your /root/cerebro folder, "git-log"
Assuming these match, the following things (needed for the study but not for Cerebro functionality) are done by /root/cerebro/install.sh but not by the Cerebro package:
- Add ypod's ssh key to your authorized_keys
- Set Cerebro to start at boot
- Add trackclient.py to your rc.local
setup_cerebro.sh in my public is a script based on install.sh (cut out the actions redundant with the package and added the git stuff) that you can use to do this. Note that if you do this, cerebroui will be in your path, whereas install.sh puts it in your home directory.
