Cent OS 7 安裝注意事項

CentOS的磁碟格式比較特別，

建議使用 Rufus來做USB安裝碟

接著安裝開啟sudoers, 以及安裝OPENSSH

１

ifconfig not found ---- yum install net-tools



２

修改/etc/ssh/ssh_config
加上
ServerAliveInterval 5
然後，重啟SSH服務：
#sudo /etc/init.d/ssh restart　或
#sudo service ssh restart

OpenStack架設使用devstack在ubuntu 14.04 and 16.04

openstack的初步探索

在經過一番架設之後還是失敗了

解決很多問題之後還是不行

看起來是pip有東西還沒裝好，不過暫時不處理了

改採用比較多使用者推薦的RDO
