tiny_web_exampleはwebapiとfrontendからなる小規模な教材用アプリケーションです。
本書ではアプリケーションの実行に必要なパッケージのインストール手順と設定方法を記述しています。
テストやパッケージ作成方法については以下のディレクトリを参照してください。
- UnitTest: tiny_web_example/webapi/spec/README.md
- IntegrationTest: tiny_web_example/spec_integration/README.md
- RPMBuild: tiny_web_example/rpmbuild/README.md
また以下の作業はrootユーザーで行ってください。
CentOS-6.6にて動作確認を行いました。それよりも古い場合は動作確認していませんので、ご了承ください。
tiny_web_exampleはmysql-serverとnginxを使用します。nginxはCentOSのBaseリポジトリには存在しないので、EPELリポジトリを利用してインストールします。
# rpm -ivh http://ftp.jaist.ac.jp/pub/Linux/Fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
実行結果例:

epelリポジトリが有効になったことを確認します。

epelが表示されていれば、epelリポジトリは有効です。
tiny_web_exampleはアプリケーションの動作にruby環境が必要です。ここではrbenvを使用してrubyとbundlerのインストールを行います。

実行結果例:
Initializing MySQL database: WARNING: The host 'vagrant-centos6' could not be looked up with resolveip. This probably means that your libc libraries are not 100 % compatible with this binary MySQL version. The MySQL daemon, mysqld, should work normally with the exception that host name resolving will not work. This means that you should use IP addresses instead of hostnames when specifying MySQL privileges ! Installing MySQL system tables... OK Filling help tables... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h vagrant-centos6 password 'new-password' Alternatively you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd /usr ; /usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd /usr/mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/bin/mysqlbug script!
