Matika版OpenStack伪生产环境部署-添加Compute节点

由于Compute计算节点太多，一个一个节点增加比较麻烦而且感觉有些做无用功，所以想办法能够自动化部署。由于初学编辑脚本，所以只写了比较简单的脚本进行部署。

编写compute安装配置脚本

将需要安装和操作的步骤编写到一个compute.sh脚本中，通过远程发送文件将脚本发送到各个compute节点并执行脚本。

编写远程发送文件脚本

编写远程发送脚本，将compute.sh脚本发送到每一个compute节点并执行

COMPUTE=$(cat /etc/hosts |grep -E "10.0.0.2|10.0.0.3" |awk -F[:" "]+ '{print $1}')
for n in $COMPUTE;do
# Copy the hosts file from localhost to ${n}host
if [ $n == '10.0.0.31']
then
echo "This is host"${n}
else
scp compute.sh ${n}:
ssh ${n} 'sh compute.sh'
fi
done
