Rails – プロジェクトの生成と確認

2021-02-28 / tau / コメントする

概要

Railsのプロジェクトの開始は、おおむね次の手順による。

プロジェクトファイル群の生成
タイムゾーン設定
MySQLサーバー起動
Railsサーバー起動

ここまででRailsが準備したデフォルトのページが表示される。

手順

プロジェクトファイル群の作成

コマンドラインで以下を実行。RailsはデフォルトでSQLiteを使うので、MySQLを使うためにはプロジェクト生成時に指定する。

rails new project_name -d mysql rails new project_name --database=mysql

project_nameでディレクトリーが作られ、その下にサブディレクトリ―やファイル群が作成される

タイムゾーンの設定

project_name/config/application.rbファイルを開く

以下の2行をclass Application...endの間、config.load_defaultsの下に追加

config.time_zone = 'Tokyo'
config.active_record.default_timezone = :local

1 2	config.time_zone = 'Tokyo' config.active_record.default_timezone = :local

database.ymlの編集

MySQLをデータベースに指定しているので、config/database.ymlの編集が必要になる。

最低限、データベースのユーザー名とパスワードをdevelopmentブロックに設定。

default: &default
adapter: mysql2
encoding: utf8mb4
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: root
password: ******
socket: /var/lib/mysql/mysql.sock
 
development:
<<: *default

default: &default

adapter: mysql2

encoding: utf8mb4

pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

username: root

password: ******

socket: /var/lib/mysql/mysql.sock

development:

<<: *default

MySQLサーバーの起動

以下のコマンドでMySQLサーバーを起動する。

sudo systemctl start mysqld

稼働状況の確認は以下のコマンド。

systemctl status mysqld

Railsサーバーの起動

プロジェクトディレクトリーに移動する。

cd project_name

サーバー起動のコマンドを実行する。

rails s

Rails 6の場合は以下。

rails s -b 0.0.0.0

確認

この段階でホスト側のブラウザーで以下のURLからRailsのデフォルト画面が表示されることを確認。

localhost:3000

ファイル配置

ディレクトリー・ファイルの配置

プロジェクトの削除

データベースを作成している場合、データベースが不要なら削除
- rails db:drop
- ただしMySQLレベルでデータベースが一切削除されてしまうので注意
プロジェクトファイル群を削除
- rm -rf project_name

実行例

実行例概要

demo_appという名前のプロジェクトを生成して結果を確認する。

最初はデータベースを設定せず、MySQLサーバーも起動しない。

プロジェクト生成

rails new demo_app -d mysql

1	rails new demo_app -d mysql

database.ymlの修正

config/database.ymlの内容を修正。

defaultブロック
- データベースがmysql2であることを確認
- usernameとpasswordを設定
developmentブロック
- database:はとりあえずコメントアウト
testブロック・productionブロック
- とりあえず全てコメントアウト

最低限の構成は以下のとおり。

default: &default
adapter: mysql2
encoding: utf8mb4
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: root
password: ******
socket: /var/lib/mysql/mysql.sock

development:
<<: *default

default: &default

adapter: mysql2

encoding: utf8mb4

pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

username: root

password: ******

socket: /var/lib/mysql/mysql.sock

development:

<<: *default

Rails – erbのコメントアウト

2021-02-27 / tau / コメントする

概要

Railsで生成される.html.erbファイル中のスクリプト部分のコメントアウトについて。

たとえば以下のコードをコメントアウトする場合。

<%= 1 + 2 %>

1	<%= 1 + 2 %>

<!– —>は使えない

HTMLのコメントアウトでは実行を抑止できない。

<!--<%= 1 + 2 %>-->

HTMLソース
<!--3-->

<!--
<%= 1 + 2 %>
-->

HTMLソース
<!--
3
-->

HTMLソース

<!--

<%= 1 + 2 %>

-->

HTMLソース

<!--

-->

#～1行コメント

Rubyの#で1行をコメントアウトできる。HTMLソース中には表示されない。

スクリプトタグの中でコメントアウトする場合、既存の<%の後ろに#を追加。

<%#= 1 + 2 %>

1	<%#= 1 + 2 %>

スクリプトタグの外でコメントアウトする場合、先頭に<%#を追加。この場合は最初に%>が現れるまでの内容がコメントになるので、末尾に%>を追加しなくてもよい。コメントアウトを戻すときも先頭の<%#だけを削除。

<%# <%= 1 + 2 %>

1	<%# <%= 1 + 2 %>

=begin…=end～複数行コメント

Rubyの=begin...=endによる複数行コメントを使う。=begin、=endとも行頭になければならない。

ファイルの末尾でエラーが出ることがあり、見栄え・打ち込みやすさの点からあまりよろしくない。

<%
=begin %>
<%= 1 + 2 %>
<%
=end %>

=begin %>

<%= 1 + 2 %>

=end %>

<% if false %>…<% end %>

falseで実行されないifクローズで該当する部分を囲む方法。

直感的にコメントだと認識し難いのが難点。

空のメソッドで囲む方法

共通で参照可能な場所に以下のような関数を定義する。

def comment
end

1 2	def comment end

そしてコメントアウトしたい部分を関数で囲む。

<% comment do %>
コメントアウトするブロック
<% end %>

<% comment do %>

<% end %>

Vagrant/CentOS7 – Railsのインストール

2021-02-26 / tau / コメントする

概要

Vagrant + VirtualBox + CentOSの環境にRuby、MySQLをインストール後、Railsをインストールするのにいろいろと躓きながら進めた記録。

構成

Vagrant : 2.2.14
VirtualBox : 6.1.18
Box : bento/CentOS-7.7
mysql : Ver 8.0.23 for Linux on x86_64
Ruby : ruby 3.0.0p0
Rails : Rails 6.1.3

インストール概略

階層が下のものは今回必要になったもの。

SELinux、firewalldの停止
Railsインストール
- sasscインストール
  - g++インストール
- mysql-develインストール
  - Node.jsインストール
Railsサーバー実行
- webpackerインストール
  - Node.jsインストール(再掲)
  - Yarnインストール

利用手順

アプリケーション生成

sqlite3がデフォルトで未インストールではエラーが出るため、コマンドラインでmysqlを指定。

rails new app_name -d mysql
rails new app_name --database=mysql

database.ymlの修正

データベースを使わない場合は、development、test、productionの各database:をコメントアウト／削除。

default: &default
  adapter: mysql2
  encoding: utf8mb4
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  username: root
  password: vagrant
  socket: /var/lib/mysql/mysql.sock

development:
  <<: *default
#  database: bbs_development

test:
  <<: *default
#  database: bbs_test

production:
  <<: *default
#  database: bbs_production
#  username: bbs
#  password: <%= ENV['BBS_DATABASE_PASSWORD'] %>

default: &default

adapter: mysql2

encoding: utf8mb4

pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

username: root

password: vagrant

socket: /var/lib/mysql/mysql.sock

development:

<<: *default

# database: bbs_development

test:

<<: *default

# database: bbs_test

production:

<<: *default

サーバー起動・接続

ここでrails sでサーバーを起動するが、ブラウザーがつながらない。

参考サイト(Rails4.2：Vagrant上の仮想マシンで起動したRailsにホストのブラウザからアクセス出来ない)のおかげで、Railsサーバーを以下で立ち上げるとよいことが分かった。

rails s -b 0.0.0.0

Linux – firewalld

2021-02-25 / tau / コメントする

概要

firewalldはファイアーウォールの機能を提供するサービス。

ステータスの確認

ステータスの確認にはsystemctlコマンドを使う。

[vagrant@localhost ~]$ systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

[vagrant@localhost ~]$ systemctl status firewalld

● firewalld.service - firewalld - dynamic firewall daemon

Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

Active: inactive (dead)

Docs: man:firewalld(1)

active (running)の場合は実行中、inactive (dead)の場合は停止中。

ステータスの設定

ステータスの設定・変更には、suでsystemctlコマンドを使う。

firewalldの有効化

有効化はsudo systemctl start firewalld。

[vagrant@localhost ~]$ sudo systemctl start firewalld
[vagrant@localhost ~]$ systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

Linux – SELinux

2021-02-25 / tau / コメントする

概要

SELinuxはシステムへのアクセス制御のための機能。

ステータスの確認

SELinuxの動作状況はgetenforceコマンドで確認。

[vagrant@localhost ~]$ getenforce
Permissive

1 2	[vagrant@localhost ~]$ getenforce Permissive

ステータスは3種類。

Permissive: アクセス制御は無効、警告メッセージを表示。
Enforcing: アクセス制御が有効。
Disabled: SELinuxは無効。

ステータスの変更

一時的な設定～setenforce

suでsetenforceコマンドを使い、Permissive/Enforcingを設定。

sudo setenforce 0/1

0でPermissing、1でEnforcing

起動時の設定～/etc/selinux/config

/etc/selinux/configファイル中、SELINUXの行をコメントアウトして設定すると、起動時のステータスが設定される。

# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - No SELinux policy is loaded.

Vagrant – MySQLのインストール – CentOS7

2021-02-24 / tau / コメントする

概要

Vagrant + VirtualBoxのCentOS7にMySQLをインストールした記録。

yumによるMySQLサイトからのダウンロード実行などのほか、パスワード設定でちょっと時間がかかった。

インストール

参考にさせていただいたサイト：【最新版】CentOSにMySQLをインストールする方法

レポジトリーへの登録

予めコンソールでVagrantのCentOSを起動しておき、MySQL Community Downloadsサイトで以下の作業。

Red Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Packageの”Download”をクリック
ダウンロードページの下部、”No thanks, just start my download.”を右クリックしてURLをコピー
CentOSのコンソールでsuとして以下を実行して、yumレポジトリーに追加

[vagrant@localhost ~]$ sudo yum install https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

パスワードの変更

初期状態でパスワードがわからない

MySQLインストール直後にrootでログインしようとしたとき、パスワードがわからずログインできなかった。

[vagrant@localhost ~]$ mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

[vagrant@localhost ~]$ mysql -u root -p

Enter password:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

ログファイルの確認

初期パスワードはログファイルに残されているとのことで、ログからパスワードを確認。

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.

Vagrant – 共有設定・カーネル更新

2021-02-23 / tau / コメントする

概要

Vagrantの仮想環境での共有フォルダ－設定
環境はWindows10、Vagrant、VirtualBox、bento/Centos-7.7
この過程でカーネルのアップデートが必要

Vagrant初期起動

bento/Centos-7.7の前にCentos/7のBoxで共有設定をしたときにvagrant-vbguestパッケージをインストール済みだったので、GuestAdditionsの不整合は解決されている様子。

ただしkernelのバージョン不整合は解決されない。

ホスト側の共有フォルダ－を作成
vagrantfileに1行追加
vagrant reloadでVagrantを再起動
仮想環境下にもフォルダーが作成され、同期される

vagrantfile設定

config.vm.synced_folder "ホスト側パス", "ゲスト側パス"

第1引数はホスト側パスで、vagrantfileからの相対パスで指定
- ホスト側で共有ディレクトリーを作成しておく必要がある
第2引数はゲストパスで、絶対パスで指定
- ゲスト側の共有ディレクトリーはVagrantが作成してくれる
