#3.前回の続き
前回の記事で作成したCentos7＋Apache2.4+MariaDB環境にRubyOnRailsを導入します。
導入にあたりpassengerと呼ばれるミドルウェアを使用するのですが、お作法がわかればそんなに難しくないです。

##3.1.諸々の追加設定

■rootで

yum install -y nodejs

yum -y install MariaDB-shared mariadb-devel

sed -i -e "$ a # rbenv" /home/butamayo/.bash_profile
sed -i -e '$ a export PATH="/home/butamayo/.rbenv/bin:$PATH"' /home/butamayo/.bash_profile
sed -i -e '$ a eval "$(rbenv init -)"' /home/butamayo/.bash_profile

mkdir -p /var/www/vhost/rails_dir

mkdir -p /var/log/httpd/{www,stg}/{80,443}

chmod 2755 -R /var/www/vhost

sed -i -e '$ a # "bundle exec" shortcut setting' /home/butamayo/.bash_profile
sed -i -e '$ a [ -f /home/butamayo/.bundler-exec.sh ] && source /home/butamayo/.bundler-exec.sh' /home/butamayo/.bash_profile

yum install -y sqlite-devel gcc-c++

yum install -y libcurl-devel httpd-devel apr-devel apr-util-devel

chmod o+x -R /var/www/vhost/rails_dir

##3.3.動作確認

■動作テスト

cd /var/www/vhost/rails_dir/www

rails g controller test index

#hostsを設定しブラウザでアクセス
http://www.butamayo.jp/test/index



cd /var/www/vhost/rails_dir/stg

rails g controller test index

#hostsを設定しブラウザでアクセス
http://stg.butamayo.jp/test/index

#4.最後に
こんな感じで設定をすればApache上でRailsを動かすことができます。Apache＋Rails（＋passenger）の記事があまりないため似たような場面に遭遇した人の助けになればうれしいです。

適当に環境作ったので動かないなどありましたら、コメントかTwitterでご指摘いただけると助かります(__)
