なぜかmariaDBがインストールされる

CentOS7にはデフォルトでmariaDBというのがはいっているとのこと
なのでそちらが優先でインストールされちゃうのかな
mariaDBmysqlは競合を起こすようなのでmysqlを入れる場合はmariaDBを削除する

一応確認
[vagrant@localhost ~]$ rpm -qa | grep -i "mariadb"
mariadb-libs-5.5.52-1.el7.x86_64
mariaDBを削除する
[vagrant@localhost ~]sudo yum -y remove mariadb-libs
古いmysqlがあったら削除する
[vagrant@localhost ~]rm -rf /var/lib/mysql/
リポジトリをインストールする
[vagrant@localhost ~]$wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
-bash: wget: command not found
wgetがないのでインストールする
[vagrant@localhost ~]$sudo yum -y install wget
再度実行

PHPUnitで簡単なテストをする2 バグ?

前回PHPUnitの簡単なテストを試してみました。

PHPUnitのdataProvider機能を使ったりしてたら気になる状態になった

テストコード

<?php

require_once ('vendor/autoload.php');

use PHPUnit\Framework\TestCase;

class testHoge extends TestCase
{
    /**
     * @dataProvider testdataProvider
     */
    public function testunittest($a, $expected)
    {
        $this->assertEquals($expected, -1);
    }

    public function testdataProvider()
    {
        return [
            [0, 0],
        ];
    }
}
?>

dataProviderを使ったコードでこれを動かすと

[vagrant@localhost html]$ vendor/bin/phpunit tests/testHoge.php
PHPUnit 5.5.7 by Sebastian Bergmann and contributors.

F.                                                                  2 / 2 (100%)

Time: 241 ms, Memory: 4.00MB

There was 1 failure:

1) testHoge::testunittest with data set #0 (0, 0)
Failed asserting that -1 matches expected 0.

/var/www/html/tests/hogeTest.php:14

FAILURES!
Tests: 2, Assertions: 1, Failures: 1.

テストは1つしかやってないはずなのに2つチェックが入ってる

1つ目は失敗してるのであってるのだが2つ目のはどこをチェックしてるんだろ

しかも成功しちゃってるし

んー  なんだろこれ

PHPUnitで簡単なテストをする

コマンド

testsフォルダを指定して***Test.phpを調べてくれる

$ vendor/bin/phpunit /tests
PHPUnit 5.5.4 by Sebastian Bergmann and contributors.

W.                                                                  2 / 2 (100%)

Time: 204 ms, Memory: 4.00MB

There was 1 warning:

1) Warning
No tests found in class "PHPUnit\Framework\TestCase".

WARNINGS!
Tests: 2, Assertions: 1, Warnings: 1.

とりあえずはテストできてるみたいだけどWARNINGSが気になる。
呼び出し方がまちがってる?

原因探るためいろいろ入れたり消したりしてたらWARNINGSが消えて何で解消できたのがか不明。

ComposerとPHPUnitのインストール

PHP使うならComposer使うといいとよく見るので導入してみました。

このエントリーはComposerのインストールとComposerでPHPUnitの導入までのメモです

composerのインストール

公式のインストール方法 https://getcomposer.org/download/

インストールをもっと簡単に

[vagrant@localhost html]$curl -sS https://getcomposer.org/installer | php

パスにあるディレクトリに移動させる

[vagrant@localhost html]$mv composer.phar /usr/local/bin/composer

composerのアップデート

[vagrant@localhost html]$composer self-update

composerのインストールはこれで完了

composer.jsonの作成

とりあえずPHPUnitを指定したのをつくる

{
    "require-dev": {
        "phpunit/phpunit": "5.5.*"
    }
}

composer installでパッケージのインストール

[vagrant@localhost html]$composer install

エラー発生

[vagrant@localhost html]$ composer install

Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - phpunit/phpunit 5.5.7 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/phpunit 5.5.6 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/phpunit 5.5.5 requires ext-dom * -> the requested PHP extension dom is missing from your system.

    - phpunit/phpunit 5.5.1 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/phpunit 5.5.0 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - Installation request for phpunit/phpunit 5.5.* -> satisfiable by phpunit/phpunit[5.5.0, 5.5.1, 5.5.2, 5.5.3, 5.5.4, 5.5.5, 5.5.6, 5.5.7].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php.ini
    - /etc/php.d/20-bz2.ini
    - /etc/php.d/20-calendar.ini
    - /etc/php.d/20-ctype.ini
    - /etc/php.d/20-curl.ini
    - /etc/php.d/20-exif.ini
    - /etc/php.d/20-fileinfo.ini
    - /etc/php.d/20-ftp.ini
    - /etc/php.d/20-gettext.ini
    - /etc/php.d/20-iconv.ini
    - /etc/php.d/20-json.ini
    - /etc/php.d/20-phar.ini
    - /etc/php.d/20-sockets.ini
    - /etc/php.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

PHPUnitの確認

vendor内にPHPUnitができてたのでこれをつかうのかな?

[vagrant@localhost html]$ vendor/bin/phpunit --version
PHPUnit 5.5.4 by Sebastian Bergmann and contributors.

なんかすごい遠回りしたけど導入できたと思う

はてぶに無限スクロールをつけるchrome-extension作った

1週間ぶりです

はてなブックマークって昔は新着ページに自動読み込みがあったはずなんですが
いまのタイル形式になってからきえちゃったみたいなんですよね。
タイル形式になってから、Greasemonkeyautopagerizeも効かないし。
もしかして機能はあって当たり前すぎて検索にも引っかからないだけなのか
あったら教えてー

プログラム始めて勉強のついでに作ってみました。

javascriptとか初心者だから調べながらやりました。
もうちょいきれいに書けたらなと思います。

github.com

使い方

  1. get cloneかdownloadする
  2. Chomeの拡張機能のでペロッパーモードにチェックをいれる
  3. 「パッケージ化されていない拡張機能を読み込む」から先程のファイルを選択する

これだけでとりあえずは動くはず。
最低限の機能(次ページ追加)だけなので
アイコンは適当だし(絵かけない)
オプションとかもないです、
読み込み中マークもでません (ちょっと待つと追加される)
あ、リストレイアウトも対応してません。(タイルレイアウトだけ)

最後に
はてなの開発の人、公式でつくってほしいです

とりあえずPHPでHelloWorld

やっと環境ができたので、

プログラムで最初にやるのはHelloWorldの表示させることでしょうか

<?php
echo "HelloWorld";
?>

まあ、表示するだけなら上ので終わりなんですよね


なので練習問題的なのを探してそれをやってみました

<?php
/**
 *
 * ループでHello World!5回表示する
 *
 * http://vipprog.net/wiki/exercise.html#eb2c4338
 *
 */
for ($i=0; $i<5; $i++) {
    echo "HelloWorld!".nl2br("\n");
}

?>

classを使うとこんな感じ?

<?php
/**
 *
 * ループでHello World!5回表示する
 *
 * http://vipprog.net/wiki/exercise.html#eb2c4338
 *
 */
class HelloWorldObj {
    private $count = 0;
    private $text = "HelloWorld!";

    public function getText() {
        return $this->text;
    }

    public function setCount($count) {
        $this->count = $count;
    }

    public function loopEcho() {
        for ($i=0; $i<$this->count; $i++) {
            echo $this->getText().nl2br("\n");
        }
    }
}
$HelloWorld = new HelloWorldObj();
$HelloWorld->setCount(5);
$HelloWorld->loopEcho();
?>

次は順番で行くとfizzbuzzかな

あとnl2brがnewline to breakって意味だってわかった

Vagrantの共有フォルダで403Forbiddenエラーがでる

Vagrantの共有フォルダをhttpdのDocumentRootとして扱う

これならWindows上でファイル編集できるからやりやすそうと思ってVagrantfileを編集してみた

config.vm.synced_folder "../data/var/www/html", "/var/www/html"

これで/html/index.htmlとか作って表示をさせたかった

アクセスしてみると403エラー

アクセスしてみると次の403エラーで表示できなかった

Forbidden
You don't have permission to access /index.html on this server.

表示させるには?

SELinuxを無効にすればとりあえずは表示するようになった

SELinuxの操作

SELinuxの確認

# getenforce
Enforcing
enforcing
SELinux機能,アクセス制限が有効
permissive
SELinuxは警告を出力、アクセス制限は無効
disabled
SELinux機能、アクセス制限がが無効

SELinuxを一時的に有効、無効にする

SELinuxを一時的に無効にする

# setenforce 0

SELinuxを一時的に有効にする

# setenforce 1

上の設定はサーバー再起動すると元に戻る

SELinuxの設定

サーバーを再起動させても設定を保持したい場合は設定ファイルを変更しないといけない

;; 設定ファイルの場所
# vi /etc/selinux/config

でファイルを開いたあとSELINUX=***の箇所を変更する

;; 有効
SELINUX=enforcing
;; 無効
SELINUX=disabled

変更したあとサーバーを再起動させる

ps

SELinuxを有効のまま表示させる方法は結局わからなかった
