How to setup †

1. Setup Linaro/Ubuntu
   1. Please look at Linaro's homepage.
2. Install softwares needed by TyhoonAE *1
   • You have to install as NOT root user.
     • OpenJDK 6
     • MySQL
     • Python
     • Erlang
     • Apache2 & proxy
     • gettext
     • xsltproc
     • expat1
   1. apt-get commands:

      $ sudo apt-get update
      $ sudo apt-get install openjdk-6-jdk mysql-server python-mysqldb libmysql++-dev libncurses5-dev libssl-dev python-dev python-setuptools libexpat1-dev gettext xsltproc erlang erlang-nox erlang-dev erlang-src apache2 libapache2-mod-proxy-html

3. Build TyhoonAE
   • You have to install as NOT root user.
   1. Download typhoonae-buildout-0.2.0
   2. Unzip to /home/linaro/tyhoonae
   3. Edit 'buildout.cfg"
      1. pcre's URL is wrong. Change to "http://vps.googlecode.com/files/pcre-8.02.tar.gz"
   4. Exec following commands:

      $ sudo python bootstrap.py
      $ ./bin/buildout

      • If you have an error & stop command, you shuold try following things:
      1. Stop "generate_app" part
      • Edit "./parts/rabbitmq/Makefile"
        Change line:

        From:
        TARGETS=$(EBIN_DIR)/rabbit.app $(INCLUDE_DIR)/rabbit_framing.hrl $(BEAM_TARGETS) 
        To:
        TARGETS=$(INCLUDE_DIR)/rabbit_framing.hrl $(BEAM_TARGETS)

        Delete line:

        $(EBIN_DIR)/rabbit.app: $(EBIN_DIR)/rabbit_app.in $(BEAM_TARGETS) generate_app
        	escript generate_app $(EBIN_DIR) $@ < $<

      1. Stop "checking erl" part
   • Edit "./eggs/rod.recipe.ejabberd-1.1.3-py2.7.egg/rod/recipe/ejabberd/__init__.py"
     Delete line:

     retcode = subprocess.call(cmd)
     if retcode != 0:
     	raise Exception("building ejabberd failed")

   • Change files:

     wget http://www.noritsuna.com/download/buildout.cfg
     wget http://www.noritsuna.com/download/ejabberd-2.1.5.tar.gz
     cp ejabberd-2.1.5.tar.gz ./downloads/

     1. If it stops other part, you shuold try again "./bin/buildout".
4. Setup configs
   1. TyhoonAE
      1. Change "typhoonae.cfg"

         datastore = mysql
         
         mysql_db = mysql
         mysql_host = [MySQL server's IP Address]
         mysql_passwd = [MySQL root's password]
         mysql_user = root

   2. MySQL
      1. Change "/etc/mysql/my.ini" *2
         Delete line:

         bind-address = 127.0.0.1

      2. Change grant connection limit

         mysql -u root -p
         grant all on *.* to root@"[your network address].%" identified by '[root password]' with grant option;

         Ex.

         grant all on *.* to root@"192.168.1.%" identified by 'pass' with grant option;

      3. If you can't connet to MySQL, you have to change MySQL's lib for Python.
         Add to "./eggs/MySQL_python-1.2.3c1-py2.7-linux-armv7l.egg/MySQLdb/connections.py"'s line 188:

         kwargs2['client_flag'] = client_flag
         kwargs2['db'] = 'mysql'
         kwargs2['host'] = '[MySQL server's IP address]'
         kwargs2['user'] = 'root'
         kwargs2['passwd'] = '[MySQL root password]'

   3. Apache
      1. Enable some mobules:

         LoadModule proxy_module modules/mod_proxy.so 
         LoadModule proxy_balancer_module modules/mod_proxy_balancer.so 
         LoadModule proxy_connect_module modules/mod_proxy_connect.so 
         LoadModule proxy_ftp_module modules/mod_proxy_ftp.so 
         LoadModule proxy_http_module modules/mod_proxy_http.so 
         LoadModule rewrite_module modules/mod_rewrite.so

      2. Edit "/etc/apache2/sites-available/001-default"
         Add following lines:

         ProxyRequests Off
         ProxyPass / balancer://cluster/ lbmethod=byrequests
         ProxyPassReverse / balancer://cluster/
         
         <Proxy *> 
         Order Deny,Allow 
         Allow from all 
         </Proxy> 
         <Proxy balancer://cluster/>
         	BalancerMember http://[Panda server's IP address]/ loadfactor=10
         	BalancerMember http://[Panda server's IP address]/ loadfactor=10
         	BalancerMember http://[Panda server's IP address]/ loadfactor=10
         </Proxy>

Install GAE application †

• Ex.Rietveld
  • Get Rietveld for panda

    wget http://www.noritsuna.com/download/rietveld-panda.tar.gz

  • Install Rietveld

    cd [TyphoonAE dir]
    ./bin/apptool  --datastore=mysql [Rietveld unziped dir]/rietveld

Manage GAE server †

• Start

  ./bin/supervisord

• Shutdown

  ./bin/supervisorctl shutdown

• Check status
