$vagrant plugin install vagrant-vbguest

Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

An error occurred while installing ffi (1.9.14), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.9.14'` succeeds before bundling.

gemインストールもNG。

Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 8443 is already in use
on the host machine.

To fix this, modify your current project's Vagrantfile to use another
port. Example, where '1234' would be replaced by a unique host port:

  config.vm.network :forwarded_port, guest: 443, host: 1234

Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn't allow modifying port forwarding. You could
try 'vagrant reload' (equivalent of running a halt followed by an up)
so vagrant can attempt to auto-correct this upon booting. Be warned
that any unsaved work might be lost.

Vagrantfileを修正。ひとまず8445に。

config.vm.network :forwarded_port, guest: 443, host: 8445

起動できた！

grafanaインストール他

新規にEC2イメージを作ったところかたスタート。まずはVirtualBoxをインストール。色々と大ハマリ。結局、Oracleページよりrpmをダウンロードしてインストール

# yum install VirtualBox-5.1-5.1.12_112440_el7-1.x86_64.rpm  --skip-broken
（中略）
飛ばしました (依存性の問題):

  libvpx.x86_64 0:1.2.0-1.0.amzn1

【参考】skip-brokenとは

続いて、Vagrantインストール。こちらも、本家よりrpmを入手してインストール。続いてGraphite。

$ wget https://github.com/obfuscurity/synthesize/archive/master.zip
$ unzip master.zip
$ cd synthesize-master/
$ vagrant plugin install vagrant-vbguest
$ vagrant up
No usable default provider could be found for your system.

Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
environments. Examples are VirtualBox, VMware, Hyper-V.

The easiest solution to this message is to install VirtualBox, which
is available for free on all major platforms.

If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
`vagrant up --provider=PROVIDER`, which should give you a more specific
error message for that particular provider.

どうもVirtualBoxがVagrantから見えない・・・。色々はまったが、Amazon　LinuxはXenで稼働しており、VirtualBoxはインストールできないとか。（仮想化上ではそもそもVirtualBoxが動かないとか）。Graphiteはソースを入手。

MacでCPUのスペックを確認する方法

家で使っているMBA(Mid 2013)ですが、買い替えをしたくてスペック調査。

bash-3.2# sysctl machdep.cpu.brand_string

machdep.cpu.brand_string: Intel(R) Core(TM) i5-4250U CPU @ 1.30GHz

bash-3.2#

GeekBenchで見るとこんな感じ。MacBookPro 13inchが3500（シングルコア）なのでもう１世代我慢かなぁ。ちなみにMac Mini Mid 2011はシングルコアで2,824、マルチコアで8,067。

Amazon fire tv stickにkodiをインストールしてDVD ISOを見れるようにした件

ずーっと欲しかったソリューション。

これまではUniversalMediaServerを使ってたけれども、Amazon fire tv stickにkodiをインストール。ただ、Macのファイル共有との相性が悪くてNFSを利用。

http://kodi.wiki/view/NFS に記載の「-N flag is set, but shares still won’t work」でハマりました。SIPが効いていたのでファイル更新ができず・・・。

SIPロック解除して、更新。完了。

Mac OS X 10.11 changed the way the user is allowed to interact with certain system files, including anything in /System/Library/LaunchDaemons/ This is due to SIP (System Integrity Protection). Follow these steps to disable SIP, set the -N option in com.apple.nfsd.plist, and re-enable SIP
