前提条件

クレジットカードをherokuに登録しておかないとmysqlのアドオンが使えません
登録しても無料範囲内なら課金されないので、登録しましょう。

herokuコマンドインストール

brew install heroku
heroku autocomplete --refresh-cache

arecore-officialを作る想定

アプリの作成(PHPのビルドパック）

heroku create arecore-official -s cedar -b heroku/php

mysqlのアドオン

heroku addons:add cleardb:ignite -a arecore-official

アプリにmysqlのURLを設定する

これでURLを調べる

heroku config -a arecore-official | grep CLEARDB_DATABASE_URL

heroku config:add DATABASE_URL='mysql://useraaaa:passbbb@hostccc.net/heroku_dbnamedddd?reconnect=true' -a arecore-official

いったん確認

heroku open -a arecore-official

リポジトリの設定

アプリ名と同じ名前でリポジトリを作成

ghq get https://github.com/noracorn/arecore-official.git

Wordpressをダウンロードして、中身をコミット

git add .
git push origin master

herokuのリモートリポジトリを入れる

heroku git:remote -a arecore-official

確認

git remote -v

wordpressの設定

cp wp-config-sample.php wp-config.php
heroku config -a arecore-official | grep CLEARDB_DATABASE_URL

この内容をかみくだいて入れる

DATABASE_URL='mysql://useraaaa:passbbb@hostccc.net/heroku_dbnamedddd?reconnect=true' -a arecore-official

wp-config.phpに

AUTH_KEYなどの設定は以下を入れる
ここにアクセスして生成する

https://api.wordpress.org/secret-key/1.1/salt/

git add .
git commit

htaccessでパーマリンクの設定

.htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
