		yum install nc
		yum install erlang.x86_64
		yum install libxslt-devel.x86_64
		yum install libxslt.x86_64
		yum install xmlto.x86_64
		cd /opt
		mkdir -p src
		cd src
		# rabbitmq install
		cd /opt/src
		wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.0.2/rabbitmq-server-3.0.2.tar.gz
		tar xzvf rabbitmq-server-3.0.2.tar.gz
		rm rabbitmq-server-3.0.2.tar.gz
		cd rabbitmq-server-3.0.2/
		export TARGET_DIR=/opt/rabbitmq-server-3.0.2
		export SBIN_DIR=/opt/rabbitmq-server-3.0.2/sbin
		export MAN_DIR=/opt/rabbitmq-server-3.0.2/man

		- mv -i rabbitmqadmin /usr/sbin
		- chmod +x /usr/sbin/rabbitmqadmin
- conf
	- vi /opt/rabbitmq-server-3.0.2/sbin/rabbitmq-defaults
	- as default disk size is too high for VESG4 VM, do that
		- edit rabbit config file so result looks like this:
			$ cat /etc/rabbitmq/rabbitmq.config
			[   
				{rabbit, [{disk_free_limit, {mem_relative, 0.1}}]}
			].
	-   
		-   
			- $RABBITMQ_HOME/etc/rabbitmq/rabbitmq-env.conf
			- $RABBITMQ_HOME/etc/rabbitmq/rabbitmq.config
