Object Storage – OpenStack Swift OpenStack을 글로만 배웠는지 아니면 책을 쓸려고 몇번해본건지.. 책쓰는 사람들이 인터넷에 OpenStack에 대해 왈가왈부 하면 정말 어이가 없어서 말이 안나온다.. 4년 전부터 OpenStack으로 이것저것 해보면서 제대로된 한글 문서하나 없다고?! 화를 냈을까? 아니다.. 다 기업 비밀이다. 그 당시는 너도나도 다 한다고 시작단계여서 알려주면 기업비밀을 노출하는 것과 같았다. 때마침 이러한 사정을 잘알고.. 첫 줄에 쓴거처럼 책을 팔려고 쓴 사람들이 뭘 알고 쓰는건지 전혀 이해할 수 없는 느낌의 전달들을 보면서 영어가 대수구나 해석만 잘하고 인용만 잘하면 책을쓰는구나 하는 생각들을 한다. 사실 업무도중에 글을 막써서 그리고 열좀 받아서.. 제대로 글을 쓰고 있는지 모르겠다. 아무튼 오늘 여기 .. 2015. 11. 2.

Change endpoint IP addresses after OpenStack installation with DevStack Change endpoint IP addresses after OpenStack installation with DevStack 통상적으로 OpenStack을 설치할때 메뉴얼따라 설치하다 보면 endpoint IP가 대부분 controller로 잡히게 된다. 내부는 상관 없으나 Public은 IP를 넣어줘야 접속이 가능하다.외부에서 연동을 위해 접속하는 통로가 바로 endpoint이기 때문이다. When working with DevStack, I occasionally run into situations where the IP address of the VM changes due to external factors. To get back up and running with the new IP addre.. 2015. 10. 13.
Openstack 외부 망과 연결(br-ex) Openstack은 설치하는 하는 과정이 다소 복잡하다. 전반적인 이해가 없는 상태에서 설치를 완료하기란 어려움이 있는 편인데 그래도 과거와 다르게 요즘은 설치 과정들을 블로그나 기타 자료등에서 쉽게 볼수 있어서 설치하는 것이 수월하다.우선.. 업무중에 잠시동안 쓰는거라.. 조금 어감이 이상하거나.. 어색한 글이 있다면 너그러이 양해를 구한다.Openstack을 구현하면 라우터 설정을 한 후 외부 망과 연동이 되지 않아 어려움이 많이 생긴다. 대부분 네트워크를 잘 모르거나 OVS를 제대로 알지 못한 상태에서 구현하기 때문에 그렇다. 메뉴얼 대로만 설치 하면 정상적으로 작동되지 않을 경우가 있을때가 간혹있다. 상황 1.외부로 나가는 br-ex에 port가 생성되지 않아 내부 구성은 끝났으나 핑이 나가질 않.. 2015. 6. 16.

SCALE HORIZONTALLY CLOUD-INIT: THE EARLY-INITIALIZATION TOOL YOU DIDN’T EVEN KNOW YOU NEEDEDFEBRUARY 24, 2013At a relatively recent cloud automation meetup I was pretty surprised to find out that a lot of folks were not using (and many unaware of) the EC2 metadata service. As this small piece has been relatively crucial to the way that we bootstrap our instances, I thought it might make sense to post about what it.. 2014. 8. 8.

Problems with hostname -f and domain name resolution on CentOS VMs Question by Traf, 6 months 3 weeks ago0In VMs I created earlier, the host name was the local IP address, with dashes instead of dots, something like 10-0-0-6.openstacklocal.Since today (1/14/2014), when I create a new CentOS 6.3 VM, it has the name I specify as the instance name, but I'm having trouble with this new name, for example when I try to start Hadoop.On the old VM, I get the following:.. 2014. 8. 8.

Logging to the Serial Console There are several ways to capture kernel log output on a remote machine. One way is to configure the kernel to use a serial port as console. If you have a machine that has a serial port, or you're running a VM, this method can be very helpful in capturing kernel log data when a panic occurs.On Debian (or Ubuntu) this is really easy to setup. Simply edit /etc/default/grub and change the line:GRUB.. 2014. 8. 7.
