PHPでcakephpプログラムを作ってみる

2020.02.14

Composerのインストール

とりあえず、何か作ってみたいと思います。どうしたら良いですか？

いきなり、冒頭から丸投げ依存モードね。まあいいわ。凄いレベルでやるからついてきてね。コンソールから、raspberripiに接続してあるかな？さあ、いきますよ！
composerというパッケージ管理ソフトからインストールします

pi@raspberrypi:~ $ curl -sS https://getcomposer.org/installer | php
All settings correct for using Composer
Downloading...

Composer (version 1.9.3) successfully installed to: /home/pi/composer.phar
Use it: php composer.phar

pi@raspberrypi:~ $ sudo mv composer.phar /usr/local/bin/composer
pi@raspberrypi:~ $ composer

cakephp4のインストール

今回はPHPの世界でも有名なcakephp4をインストールしていきます。分かりやすいように、多少強引に説明しておきます。もっと良い方法があるんじゃないかと思えるようになったら、成長した証よ。
引き続き、コマンドでいくわよ。

pi@raspberrypi:/var/www $

思わず、http://192.168.0.10/ とやってみる
※raspberrypiのIPアドレスが192.168.0.10の場合

上のように何かが表示されるはずです。でももうちょいですよ
config/app_local.phpファイルを編集してみます

//36行目あたり.....
    'Datasources' => [
        'default' => [
            'host' => 'localhost',
            /*
             * CakePHP will use the default DB port based on the driver selected
             * MySQL on MAMP uses port 8889, MAMP users will want to uncomment
             * the following line and set the port accordingly
             */
            //'port' => 'non_standard_port_number',

            'username' => 'yamada',
            'password' => 'tarou',
            'database' => 'food',

上記のように、データーベースの接続情報を修正してみましょう。
あと、実はデザインがおかしいです。mod_rewriteを有効化させましょう
a2enmod という命令を使います

pi@raspberrypi:~ $ sudo a2enmod rewrite
Enabling module rewrite.
To activate the new configuration, you need to run:
  systemctl restart apache2
pi@raspberrypi:~ $ sudo systemctl restart apache2

Adminerのインストール

超初心者向けということで、今回はAdminerをインストールします

pi@raspberrypi:~ $ sudo wget http://www.adminer.org/latest.php -o /var/www/html/adminer.php

http://192.168.1.10/adminer.php
とアクセスすることで、データベースの中身を簡単に見れるようになりました。分かりやすいかも。

Githubにアップしよう

せっかくここまでやったので、保存しておきたいのですが。

そうね。せっかくなのでGitHubの使い方にもなれておきましょう。お友だちと共有するのにも役立ちそうですよ

まずは、インストール

pi@raspberrypi:~ $ sudo apt-get install git-flow
pi@raspberrypi:~ $ git flow
usage: git flow <subcommand>

Available subcommands are:
   init      Initialize a new git repo with support for the branching model.
   feature   Manage your feature branches.
   bugfix    Manage your bugfix branches.
   release   Manage your release branches.
   hotfix    Manage your hotfix branches.
   support   Manage your support branches.
   version   Shows version information.
   config    Manage your git-flow configuration.
   log       Show log deviating from base branch.

Try 'git flow <subcommand> help' for details.

こんなふうに出来たらインストールはOK。
まずは、バージョン管理に入れるための初期設定から。
今回は、/var/www/htmlに配置しているので、そのディレクトリでやります

pi@raspberrypi:~ $ cd /var/www/html
pi@raspberrypi:/var/www/html $ git init
Initialized empty Git repository in /var/www/html/.git/

すでに作成ずみのgithubのレポジトリにアップできるようにしましょう。まだない人は作成してね。

pi@raspberrypi:/var/www/html $ git config --global user.email "[email protected]"
pi@raspberrypi:/var/www/html $ git config --global user.name "myname"
pi@raspberrypi:/var/www/html $ git flow init
No branches exist yet. Base branches must be created now.
Branch name for production releases: [master]
Branch name for "next release" development: [develop]

How to name your supporting branch prefixes?
Feature branches? [] feature/
Bugfix branches? [] bugfix/
Release branches? [] release/
Hotfix branches? [] hotfix/
Support branches? [] support/
Version tag prefix? [] 
Hooks and filters directory? [/var/www/html/.git/hooks]
pi@raspberrypi:/var/www/html $ git add .
pi@raspberrypi:/var/www/html $ git commit -m "my first commit"
pi@raspberrypi:/var/www/html $ git remote add origin [email protected]:my-githubaccout-name/repo-name.git
pi@raspberrypi:/var/www/html $ git push origin develop

あれ、権限がないので、最後の行でエラーが出ました。鍵認証でしたっけ？

そうね。では、githubにアップできるように設定していきましょう

githubに繋がる鍵を作成する

pi@raspberrypi:/var/www/html $ cd ~/.ssh
pi@raspberrypi:~/.ssh $ ls
authorized_keys  known_hosts
## ここでid_rsaなどがあれば、以下、別のものを指定する。たとえば、id_raspberrypiなど何でもOK
pi@raspberrypi:~/.ssh $ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/pi/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/pi/.ssh/id_rsa.
Your public key has been saved in /home/pi/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:LYxAHubEsGps6zbfY0ThPDovIZnLixhQBKB7dg8b7OU pi@raspberrypi
The key's randomart image is:
+---[RSA 2048]----+
|+.oo=            |
|o.o B E          |
|+* ..+           |
|+o+.o..          |
+----[SHA256]-----+
pi@raspberrypi:~/.ssh $ ls
authorized_keys  id_rsa  id_rsa.pub  known_hosts
pi@raspberrypi:~/.ssh $ cat id_rsa.pub
.............................................
.............................................

このid_rsa.pubのファイルの中身をgithubに登録します
githubの画面、右上の写真をクリックして出てくるメニューで、Settingをクリックします

上の図で、SSHのところにある、New SSH keyをクリックします。
フォームがでてくるので、先程コンソールで、 cat id_rsa.pub と打ち込んだときに表示されたものを登録します

再度、コンソールに戻って、もう一度pushしてみましょう

pi@raspberrypi:/var/www/html $ git push origin develop
Enumerating objects: 105, done.
Counting objects: 100% (105/105), done.

remote: Resolving deltas: 100% (12/12), done.
To github.com:hashimototakeshi/foodloss.git
 * [new branch]      develop -> develop

できました。

長くなってきたので、また次回
