Matika版OpenStack偽生產環境部署-新增Compute節點
阿新 • • 發佈：2019-02-06
由於Compute計算節點太多，一個一個節點增加比較麻煩而且感覺有些做無用功，所以想辦法能夠自動化部署。由於初學編輯指令碼，所以只寫了比較簡單的指令碼進行部署。
編寫compute安裝配置指令碼
將需要安裝和操作的步驟編寫到一個compute.sh指令碼中，通過遠端傳送檔案將指令碼傳送到各個compute節點並執行指令碼。
#!/bin/bash
HOST_IP=$(ifconfig |grep 'inet '|awk '{ print $2}'|grep '10')
systemctl stop firewalld.service
systemctl disable firewalld.service
sed -i "s/SELINUX=enforcing/SELINUX=disabled/" 編寫遠端傳送檔案指令碼
編寫遠端傳送指令碼，將compute.sh指令碼傳送到每一個compute節點並執行
COMPUTE=$(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
