シンボリックリンクの削除のメモ(ファイルも削除されるかどうかの検証)

Jul 3, 2015

AD:

先日バックアップも何もない環境で、ディスク・スペースが100%になり急遽パーミッションを追加してサイトのフォルダの移設が必要なったのですが、サイトのいたるところにシンボリックリンがはられていて、シンボリックリンク（ハードも含めて）の削除がどのようになるか、非常に怖かったのメモしておきます。

シンボリックリンクを削除したらリンク元も消えるのか気になったのですが、unlinkで削除すれば参照元は消えることはないようです。
ですが、リンクしていたファイルは消えるので、必要な場合はcpなどでファイルを持ってきておきます。

$ cd /home/hoge/
$ ls -al
setting.php -> /var/www/test/setting.php
$ unlink ./setting.php
$ ls -al
..
$ cp /var/www/test/setting.php ./

Vagrant Rails 4.2 in Mac で dev.domain:3000等でアクセスできない

Mar 26, 2015

AD:

最新のプロジェクトをVagrant Ruby 2.2.1 & Ruby on Rail 4.2.1の最新安定バージョンで開発を開始いたのですが、Vagrantの内のRails Appにhttpでアクセスがうまくできなかったのでその際のメモです。

状況

VagrantのUbuntuにrbenvでRubyをインストールしております。
各種Appには、/etc/hostsに独自ドメインを指定してアクセスしております。

$ sudo vi /etc/hosts
192.168.33.10 dev.domain

1 2	$ sudo vi /etc/hosts 192.168.33.10 dev.domain

アクセスは下記のようなドメインでやっております。
http://dev.domain:3000

解決方法

いきなり解決方法です。

$ rails s -b 0.0.0.0
=> Booting Puma
=> Rails 4.2.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Puma 2.11.1 starting...
* Min threads: 0, max threads: 16
* Environment: development
* Listening on tcp://0.0.0.0:3000

$ rails s -b 0.0.0.0

=> Booting Puma

=> Rails 4.2.1 application starting in development on http://0.0.0.0:3000

=> Run `rails server -h` for more startup options

=> Ctrl-C to shutdown server

Puma 2.11.1 starting...

* Min threads: 0, max threads: 16

* Environment: development

* Listening on tcp://0.0.0.0:3000

問題なのは、Rails4.2のbindsが0.0.0.0が127.0.0.1になっているので、-bで指定して立ち上げることが解消できます。

An error occurred while installing nokogiri (1.5.2), and Bundler cannot continue.

Make sure that `gem install nokogiri -v '1.5.2'` succeeds before bundling.

解決方法

NokogiriとUbuntuで下記のもので入るようになるとはあるのですが、1.5.2はこれでもうまく行かず。。

sudo apt-get install libxml2-dev libxslt1-dev

1	sudo apt-get install libxml2-dev libxslt1-dev

下記のオプションをつけてなんとかインストールできました。

sudo gem install nokogiri -v '1.5.2'  -- --with-cflags="-O2 -pipe -march=native -w"

1	sudo gem install nokogiri -v '1.5.2' -- --with-cflags="-O2 -pipe -march=native -w"

Rails 4.0.0 & Ruby 2.0.0でdebuggerでReadlineのエラー

Aug 9, 2013

AD:

せっかく新しい案件が来たので、Ruby2 & Rails4で開発しているんですが、debuggerでReadlineのエラーがでたので、メモしておきます。

まず環境

Vagrantのubuntu12.10.64bit
rbenv – Ruby 2.0.0p247
rbenv – Rails 4.0.0

エラー内容

$ rails s --debugger
/home/vagrant/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/debugger-1.6.1/lib/ruby-debug/interface.rb:67:in `block (2 levels) in initialize': uninitialized constant Debugger::LocalInterface::Readline (NameError)

1 2	$ rails s --debugger /home/vagrant/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/debugger-1.6.1/lib/ruby-debug/interface.rb:67:in `block (2 levels) in initialize': uninitialized constant Debugger::LocalInterface::Readline (NameError)

エラーを読みかぎりReadlineがないらしいので、Readlineをインストール

Readlineを指定して、rbenvでRubyを入れなおし

$ sudo apt-get install libreadline6 libreadline6-dev
$ CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline" rbenv install 2.0.0-p247
$ rbenv global 2.0.0-p247
$ rbenv rehash

$ sudo apt-get install libreadline6 libreadline6-dev

$ CONFIGURE_OPTS="--with-readline-dir=/usr/include/readline" rbenv install 2.0.0-p247

$ rbenv global 2.0.0-p247

$ rbenv rehash

could not bind IPv4 socket: Cannot assign requested address エラー by PostgreSQL

VagrantのUbuntuにPostgreSQLをインストールして、立ち上げようとすると下記のようなエラーがでたので、メモしておきます。

エラー内容

$ apt-get update

解決方法

コネクション指定の問題なので、下記のように変更しました。

$ vi /etc/postgresql/9.1/main/postgresql.conf
#listen_addresses = 'localhost'
&#12288;&darr;
listen_addresses = '*'

$ vi /etc/postgresql/9.1/main/postgresql.conf

#listen_addresses = 'localhost'

　↓

listen_addresses = '*'
