## **addComputeNode.sh** is a tool to add nova-compute node to OpenStack cloud computing service.
## [email protected] (Kayven)
## Learn more and get the most recent version at http://code.google.com/p/onestack/
set -o xtrace
## 请使用root执行本脚本！
## Ubuntu 12.04 ("Precise") 部署 OpenStack Essex，在client管理OpenStack安装nova管理工具
## 参考：
## http://docs.openstack.org/essex/openstack-compute/starter/content/

## 2、自行检查下面network/interfaces的两个网卡设置
ServerControlIP="192.168.139.50"
computeControlIP="192.168.139.150"
## token, 登录dashboard密码
ADMIN_TOKEN="admin"
## network configure
NETWORK_CONF=${NETWORK_CONF:-"/etc/network/interfaces"}
cat <<INTERFACES >$NETWORK_CONF
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
pre-up ifconfig eth0 hw ether b8:ac:6f:9a:ee:e5

sed -i -e "s/192.168.139.51/$computeControlIP/g" $NETWORK_CONF
/etc/init.d/networking restart
## 配置 /etc/nova/nova.conf，这里与控制节点的配置相同！比如ip是控制节点的ip
MYSQL_PASSWD=${MYSQL_PASSWD:-"cloud1234"}
NOVA_DB_USERNAME=${NOVA_DB_USERNAME:-"novadbadmin"}
NOVA_DB_PASSWD=${NOVA_DB_PASSWD:-"cloud1234"}
OUT_IP="192.168.139.50"
OUT_IP_PRE="192.168.139"
IN_IP="10.0.0.1"
IN_IP_PRE="10.0.0"
FLAT_IP="10.0.0.40"
FLOAT_IP="192.168.139.225"
## 选择虚拟技术，裸机使用kvm，虚拟机里面使用qemu
VIRT_TYPE="qemu"

## 3、安装bridge-utils、ntp
apt-get install -y bridge-utils ntp
echo "server $ServerControlIP" > /etc/ntp.conf
service ntp restart
## 4、安装nova
apt-get install -y nova-compute
## 配置 /etc/nova/nova.conf，这里与控制节点的配置相同！比如ip是控制节点的ip
## 如果你是在虚拟机里测试Openstack。你需要把默认的虚拟化引擎从kvm改成qemu。
