*How to setup [#b4562a9c]
+Setup Linaro/Ubuntu
++Please look at [[Linaro's homepage:http://www.linaro.org/downloads/]].
+Install softwares needed  by [[TyhoonAE:http://code.google.com/p/typhoonae/]] ((work on Linaro/Ubuntu for Pandaboard))
--You have to install as ''NOT'' root user.
---OpenJDK 6
---MySQL
---Python
---Erlang
---Apache2 & proxy
---gettext
---xsltproc
---expat1
++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
+Build [[TyhoonAE:http://code.google.com/p/typhoonae/]]
--You have to install as ''NOT'' root user.
++Download [[typhoonae-buildout-0.2.0:http://typhoonae.googlecode.com/files/typhoonae-buildout-0.2.0.tar.gz]]
++Unzip to ''/home/linaro/tyhoonae''
++Edit 'buildout.cfg"
+++pcre's URL is wrong. Change to "http://vps.googlecode.com/files/pcre-8.02.tar.gz"
++Exec following commands:
 $ sudo python bootstrap.py
 $ ./bin/buildout
---If you have an error & stop command, you shuold try following things:
+++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) $@ < $<
+++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/
+++If it stops other part, you shuold try again "./bin/buildout".
+Setup configs
++[[TyhoonAE:http://code.google.com/p/typhoonae/]]
+++Change "typhoonae.cfg"
 datastore = mysql
 
 mysql_db = mysql
 mysql_host = [MySQL server's IP Address]
 mysql_passwd = [MySQL root's password]
 mysql_user = root
++MySQL
+++Change "/etc/mysql/my.ini" ((This setting has some security issues. If you want to provide this server to Internet, you should research about the following things!!!))~
Delete line:
 bind-address = 127.0.0.1
+++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;
+++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]'
++Apache
+++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
+++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/>
