Ubuntu 에서 데몬 관리

RedHat 계열은 ntsysv

Ubuntu 는 rcconf 설치해서

$ sudo apt-get install rcconf

devstack 및 trove 설치하기

1. physical machine or VM 에 ubuntu 12.04 or 14.04 가 설치 되어있다고 가정함

2. Ubuntu upgrade

최신 패키지로 업그레이드함

필요시 재부팅

sudo apt-get update

sudo apt-get upgrade

sudo shutdown -ry 0

3. proxy 환경 설정

사내 등에서 proxy 서버가 있는 환경인 경우 proxy 인증서(xxx.crt) 를 다운받아서 아래 위치에 복사함

/usr/share/ca-certificates/extra/xxx.crt

인증서 복사 후 아래 명령어로 인증서를 시스템에 등록함

sudo dpkg-reconfigure ca-certificates (yes, xxx.crt 선택)

Proxy 세팅을 위해 /etc/environment 파일에 아래 내용을 추가합니다. Virtual box 는 10.0.0.0/8 subnet 을

기본으로 사용함

ubuntu@ubuntu:~$ sudo vi /etc/environment

...

http_proxy="http://a.b.c.d:8080/"

https_proxy="https://a.b.c.d:8080/"

no_proxy="localhost,127.0.0.1,127.0.0.0/8,127.0.1.1,10.0.0.0/8"

4. devstack 설치

4.1 git, pip 설치/설정

Python Package 관리 도구인 PIP 와 형상관리도구 Git 을 설치합니다.

ubuntu@ubuntu:~$ sudo apt-get install git python-pip

ubuntu@ubuntu:~$ sudo vi ~/.pip/pip.conf

[global]

cert = /usr/share/ca-certificates/extra/xxx.crt

4.2 devstack download

$ git clone http://github.com/openstack-dev/devstack

$ cd ~/devstack

$ git checkout stable/juno

4.3 local.conf 편집

VERBOSE=True

LOG_COLOR=True

SCREEN_LOGDIR=/opt/stack/logs

4.4 stack.sh 실행

ubuntu@ubuntu:~/devstack$ ./stack.sh

screen -x stack 을 통해 각 데몬들이 정상인지 확인

웹브라우저를 통해 Horizon 에 접속해서 테스트 가능

5. Troubleshooting
5.1 아래 에러 나는 경우
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement pip in /usr/local/lib/python2.7/dist-packages

pip.conf 파일에 아래 라인 추가/변경
index-url = http://pypi.gocept.com/simple/

5.2 아래 에러
No such file or directory: '/usr/lib/python2.7/dist-packages/setuptools.egg-info'

-> 아래 링크 참조해서 다음과 같이 조치
http://stackoverflow.com/questions/28441674/error-while-installing-icehouse-openstack-using-devstack

sudo rm /usr/lib/python2.7/dist-packages/setuptools.egg-info sudo apt-get install --reinstall python-setuptools

windows curl 에서 no proxy 하는 법

windows 환경에서 curl 을 사용하는데, 사내 proxy 안 거치고 바로 접속해야 하는 경우, 예를 들어 local VM 등

_curlrc 파일에 아래와 같은 라인 추가
noproxy=192.168.21.140

Install PyCharm and JDK on Ubuntu 12.04

Download the sun jdk 8 tar file from here
Extract the tar file:
```
$ tar -xvzf jdk1.8.0_25.tar.gz
```

Move extracted folder to this location:

$ sudo mv jdk1.8.0_25 /usr/lib/jvm/

Install new java source in system:

$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8.0_25/bin/javac 1

$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0_25/bin/java 1

$ sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.8.0_25/bin/javaws 1

Choose default java:

$ sudo update-alternatives --config javac

$ sudo update-alternatives --config java

$ sudo update-alternatives --config javaws

java version test:

$ java -version

Verify the symlinks all point to the new java location:

$ ls -la /etc/alternatives/java*

Enable Java plugin for Mozilla Firefox (even for Chrome)

#for 64-Bit jdk

$ sudo ln -s /usr/lib/jvm/jdk1.8.0_25/jre/\

JAVA_HOME configuration:

Some tools require JAVA_HOME variable. You can set JAVA_HOME in Ubuntu so simple: Edit the file .bashrc under your home directory and add the following lines: (if .bashrc is hidden click in Nautilus Menu View > Show Hidden Files)

export JAVA_HOME=/path/your/jdk

export PATH=$JAVA_HOME/bin:$PATH

windows 에서 python 2.x 와 3.x 동시 설치 사용하기

1. http://www.python.org 에서 2, 3 버전 다운로드

2. python 3.x 설치 후 2.x 설치 (저는 2 설치하고 3 설치했더니 에러나네요)

3. 각 버전 설치하면서 그냥 디폴트로 설치합니다. 특히 python.exe 있는 폴더를 경로에 추가하지 않습니다.

4. 모두 설치하면 py.exe 가 예를 들어 C:\Windows\py.exe 로 있을 겁니다. 이건 3 버전 설치하면 나오는 건데 py --help 라고 치시면 설명 나오지만 python launcher 라고 보시면 됩니다.

py.exe 실행하면 2.x 버전 실행되고, py -3 이라고 하면 3.x 버전 실행됩니다.

참고로 환경변수에 PYTHONPATH 같은 것이 없어야 합니다. 있으면 py -3 등을 할 때 에러 발생할 수 있습니다.

py.exe 가 환경까지 알아서 잘 세팅해주는 것 같습니다.

proxy 환경에서 docker build 하는 경우

회사 내부 등의 이유로 어쩔 수 없이 proxy 를 사용하는 경우 아래 3가지를 해준다
(참고로 필자는 Ubuntu 14.04 사용)

1. /etc/environment 파일에 proxy 정보 추가
예) http_proxy="http://a.b.c.d:8080/"
4 https_proxy="http://a.b.c.d:8080/"
5 no_proxy="localhost,127.0.0.1,127.0.0.0/8,127.0.1.1,10.0.0.0/8,192.168.0.0/16"

2. /etc/default/docker.io 파일에 proxy 정보 추가
예)
# If you need Docker to use an HTTP proxy, it can also be specified here.
export http_proxy="http://a.b.c.d:8080/"
export no_proxy=192.168.21.140

3. Dockerfile 에 proxy 정보 추가
예)
ENV http_proxy http://a.b.c.d:8080/
ENV https_proxy http://a.b.c.d:8080/

vagrant up 실행시 에러 나는 경우 처리

아래와 같은 에러 나는 경우:

vagrant up
The provider 'virtualbox' that was requested to back the machine
'core-01' is reporting that it isn't usable on this system. The
reason is shown below:

Vagrant could not detect VirtualBox! Make sure VirtualBox is properly installed.
Vagrant uses the `VBoxManage` binary that ships with VirtualBox, and requires
this to be available on the PATH. If VirtualBox is installed, please find the
`VBoxManage` binary and add it to the PATH environmental variable.

->

(This PC -> Advanced System Settings -> Environmental Variables -> Search for VBOX_MSI_INSTALL_PATH and change it to VBOX_INSTALL_PATH)

이렇게 바꾸면 된다
