railsをapacheでうごかすpassengerをいれてみた centos 6.4 sakuraのVPS

いちいちwebrick立ち上げるのもめんどくさいなあとおもい、やってみる。

http://redmine.jp/tech_note/apache-passenger/
この手順に従った。

ちなみに、私の環境ではrbenvを使ってます。

まずやってみる

$ gem install passenger

できた

$ passenger-install-apache2-module

これがコマンド見つからない。
環境変数が反映されてないせいだと見当がついたが、どこに書いてあるか分からんし面倒だからいったんログアウトした。
再度チャレンジしたらできた。

対話式なのか！こんなのでてきたので、エンターを押す

Welcome to the Phusion Passenger Apache 2 module installer, v4.0.40.

This installer will guide you through the entire installation process. It
shouldn't take more than 3 minutes in total.

Here's what you can expect from the installation process:

 1. The Apache 2 module will be installed for you.
 2. You'll learn how to configure Apache.
 3. You'll learn how to deploy a Ruby on Rails application.

Don't worry if anything goes wrong. This installer will advise you on how to
solve any problems.

Curl development headers with SSL support
Apache 2 development headers
Apache Portable Runtime (APR) development headers
Apache Portable Runtime Utility (APU) development headers

この4つが入ってないが、インストール方法を教えてくれるらしい。
Enterを押すとこんなん出てきた。

--------------------------------------------

Installation instructions for required software

 * To install Curl development headers with SSL support:
   Please install it with yum install curl-devel

 * To install Apache 2 development headers:
   Please install it with yum install httpd-devel

 * To install Apache Portable Runtime (APR) development headers:
   Please install it with yum install apr-devel

 * To install Apache Portable Runtime Utility (APU) development headers:
   Please install it with yum install apr-util-devel

If the aforementioned instructions didn't solve your problem, then please take
a look at the Users Guide:

  /home/XXXXX/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.40/doc/Users guide Apache.html
  http://www.modrails.com/documentation/Users%20guide%20Apache.html

足りないものをインストール

以下のようにインストール

$ sudo yum install curl-devel httpd-devel apr-devel apr-util-devel

パスワード聞かれます。
何をインストールするかリストがでてきて、これでいいか？ってきかれるのでy押してenter.

再チャレンジ

$ passenger-install-apache2-module

Enter2回でapacheのコンパイルが始まる。
結構長い。
字がじゃんじゃん出てきます。

終わるとこんなのがでてくる。
httpd.confに追記しないといけないんだろう。

--------------------------------------------
Almost there!

Please edit your Apache configuration file, and add these lines:

   LoadModule passenger_module /home/XXXXX/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.40/buildout/apache2/mod_passenger.so
   <IfModule mod_passenger.c>
     PassengerRoot /home/XXXXX/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.40
     PassengerDefaultRuby /home/XXXXX.rbenv/versions/1.9.3-p484/bin/ruby
   </IfModule>

After you restart Apache, you are ready to deploy any number of web
applications on Apache, with a minimum amount of configuration!

Press ENTER to continue.

エンター押すと、バーチャルホストの設定もでてきた。

--------------------------------------------

Deploying a web application: an example

Suppose you have a web application in /somewhere. Add a virtual host to your
Apache configuration file and set its DocumentRoot to /somewhere/public:

   <VirtualHost *:80>
      ServerName www.yourhost.com
      # !!! Be sure to point DocumentRoot to 'public'!
      DocumentRoot /somewhere/public    
      <Directory /somewhere/public>
         # This relaxes Apache security settings.
         AllowOverride all
         # MultiViews must be turned off.
         Options -MultiViews
      </Directory>
   </VirtualHost>

And that's it! You may also want to check the Users Guide for security and
optimization tips, troubleshooting and other useful information:

設定

apacheの設定ファイル httpd.confの場所を忘れたので、locateで探す

$ locate httpd.conf
/etc/httpd/conf/httpd.conf

これをvimで開いて上のを書き加える

sudo vi /etc/httpd/conf/httpd.conf

viコマンドで開いたら、/でLoadModuleという文字列を探す。

/LoadModule

たくさんLoadModuleって書いてあるところがあるから、その末尾に上の文字列をいれよう。
私の環境ではこんなんになった。

/etc/httpd/conf/httpd.conf

*略
LoadModule cgi_module modules/mod_cgi.so
LoadModule version_module modules/mod_version.soLoadModule passenger_module /home/XXXXX/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.40/buildout/apache2/mod_passenger.
so   
<IfModule mod_passenger.c>
    PassengerRoot /home/XXXXX/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.40
    PassengerDefaultRuby /home/XXXXX.rbenv/versions/1.9.3-p484/bin/ruby
</IfModule>

さらに、バーチャルホストの設定。
同じファイルの一番下に書き込む。

/etc/httpd/conf/httpd.conf

略

<VirtualHost *>
DocumentRoot /home/XXXX/Tameshi/public
ServerName あなたのほすと
HostNameLookups double
UseCanonicalName off
    <Directory /home/XXXX/Tameshi/public>
        Allow from all
        Options -MultiViews
    </Directory>
</VirtualHost>

DocumentRootには、railsアプリのディレクトリ中のpublicディレクトリを指定する。
上の例では、自分のユーザのhomeにアプリをつくることにしてる。

最後に、apacheの再起動

$ sudo service httpd restart

試しにアプリを動かす

さて、これでインストールは終了したはず。
/var/www/html以下にRailsのファイルを置いて、動かしてみる。

http://d.hatena.ne.jp/maeharin/20130212/rails_generate
ここを参考に、scaffoldで空のrailsアプリを作る。

$ cd /var/www/html
$ rails new Tameshi
$ cd Tameshi
$ rails g scaffold hito name:string

と思ったらエラー。
javascriptエンジン関連だろう。
本筋と関係ないが、全部のせる。

Gemflieを書き換えて、therubyracerのコメントアウトを外す

$ vi Gemfile

 # See https://github.com/sstephenson/execjs#readme for more supported runtimes
 gem 'therubyracer', platforms: :ruby
略

$ bundle install

これで行けたはず。
