Network APIを作成するための環境構築(Ruby、Sinatra、ActiveRecord)

Last updated at Posted at 2015-10-30

マシン環境

cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)

Rubyインストール

CentOSのdefaultのrubyのバージョンは一旦古いため、削除 :triumph:
yum remove ruby

Rubyソースのコンパイルのために下記をインストール
yum -y install gcc zlib-devel openssl-devel sqlite sqlite-devel mysql-devel readline-devel libffi-devel

Ruby2.2.3をインストール(結構時間かかる :sleeping:

cd /usr/local/src
wget https://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.3.tar.gz
tar zxvf ruby-2.2.3.tar.gz
cd ruby-2.2.3
./configure
make
make install

確認 :laughing:

ruby -v
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

MySQLインストール

yum -y install mysql
確認(MariaDBになってる :laughing:

mysql --version
mysql  Ver 15.1 Distrib 5.5.44-MariaDB, for Linux (x86_64) using readline 5.1

これも必要っぽい。
yum install mariadb-server

systemctl enable mariadb.service
systemctl start mariadb.service

初期パスワード設定
/usr/bin/mysqladmin -u root password 'new-password'

初期設定
mysql_secure_installation

Sinatra、Nokogiri、Netconfなどなどのインストール

そこそこ時間かかります :sleeping:

gem install sinatra
gem install netconf
gem install nokogiri
gem install activerecord
gem install mysql2
gem install netaddr
gem install sinatra-contrib
gem update
gem update --system
gem uninstall mysql2  #(0.4.1)
gem install mysql2 -v 0.3.20

mysql2のバージョンが新しいと上手く動かなかったので、0.3.20に落とした :astonished:
updateも一応した :dash:
NetAddrはあんまり使ってる人いなさそうな感じですが、すごく便利 :kissing_heart:
