webアプリケーションを動かす上で忘れちゃうんでメモ間違ってたらごめんなさい

構成

ruby 2.3.1 rails 5.0.1 nginx capistrano puma conoha - centOS 6.7 64bit

#/etc/nginx/conf.d/hoge.conf

upstream #{app_name} {
  # uncomment the following line if multiple application servers are used.
  # this will force nginx to send requests from the same client to the same
  # application server.
  # ip_hash;

}

server {
  listen 80 default deferred;

  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;

}

起動する

sudo service nginx start

ちょいハマったところ

設定を変更したらrestartする
server unix:
server_name

# nginxをrestartする
$ sudo service nginx restart

mysqlのinstall

インストール

$ yum -y install mysql-devel
$ yum -y install mysql-server

起動

$ /etc/rc.d/init.d/mysqld start

接続

$ mysql

ちょいハマったところ

bundle installの部分でエラーが出る時下記二つ実行

yum install gcc-c++
yum install mysql-devel

他の解説でよく使われていたset :scm, :gitを使用すると上手く動かなかったため、Capfileに下記を追加した

require "capistrano/scm/git"
install_plugin Capistrano::SCM::Git

ログの確認

$ tail -f /var/www/#{app_name}/shared/log/production.log

まとめ

VPSを借りての構築が初めてだったので結構ハマった。 yum installが面倒くさいときは下記実行

$ yum -y install git readline-devel gcc-c++ mysql-devel mysql-server openssl-devel

Naturally
