ユーザー作成

インスタンス構築時に指定した公開鍵に対応する秘密鍵を用いて ubuntu ユーザーでログインして以下を実行

sudo su -
# useradd -u 10011 -d /home/kazutake -s /bin/bash -m kazutake -G admin
# mkdir /home/kazutake/.ssh
# echo *******' > /home/kazutake/.ssh/authorized_keys
# chown -R kazutake:kazutake /home/kazutake/.ssh
# chmod 700 -R /home/kazutake/.ssh
# chmod 600 -R /home/kazutake/.ssh/*
# sed -i '/^kazutake:.*$/d' /etc/shadow
# sudo passwd kazutake
#パズワード入力

以降、上記で作成した kazutakeユーザーで作業を行う
ubuntu ユーザーをログアウトし、 kazutake ユーザーで ssh 経由でログインする

NTP設定

# apt update
# apt install -y ntp net-tools

アプリ用アカウント作成

# groupadd dev -g 2000
# adduser --gid 2000 --uid 2100 deploy

Ruby のインストール

# sudo su - deploy

以下、 deploy ユーザー

$ git clone https://github.com/rbenv/rbenv.git ~/.rbenv
$ echo 'export PATH="~/.rbenv/bin:$PATH"' >> ~/.bashrc
$ ~/.rbenv/bin/rbenv init >> ~/.bashrc
$ echo 'eval "$(rbenv init - bash)"' >> ~/.bashrc
$ source ~/.bashrc
$ git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
$ rbenv  install 3.2.2

デプロイユーザーの調整

# sudo su - deploy

以下、 deploy ユーザー

$ ssh-keygen -C ''

入力は全てデフォルトで enter キーを押下していく

自分自身にSSHできるようにする

$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

ソースコードを展開する
※事前に /home/deploy/.ssh/id_rsa.pub の公開鍵を　git に登録してソースコードを取得できるようにする
以下、 deploy ユーザー

$ git clone git@github.com:yakuzaiko/zaiko.git /home/deploy/zaiko
$ cd ~/zaiko

$ vi config/master.key

内容を記載して保存

$ vi /usr/local/rails_apps/zaiko/shared/config/master.key
内容を記載して保存

$ bundle

DBを用意する
以下、 deploy ユーザー

$ cd ~/zaiko
$ RAILS_ENV=production bin/rails db:create db:migrate db:seed

試しに起動する
以下、 deploy ユーザー

$ cd ~/zaiko
$ RAILS_ENV=production bin/rails assets:clean assets:precompile
$ RAILS_LOG_TO_STDOUT=1 RAILS_ENV=production bin/rails s
