Challenge!

rails5.0+nginx1.11.8+puma3.6.2+CentOS6.7でrails環境構築

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

目次

VPS

vpsは検討の末conohaのvpsを使用 ssh接続のための接続等は省略しておきます。 とりあえずrootでログイン

ログイン

ssh root@xxx.xxx.xx.xx (xxx.xxx.xx.xxはサーバのIPアドレス)

公開鍵を設定してない場合

簡単に設定が可能

$ brew install ssh-copy-id
# -i オプションを使うと、登録する公開鍵を選べる。
$ ssh-copy-id hoge_user@hogehoge.hoge.com

rbenvをinstall

rubyを管理するためにrbenvをインストール rbenvをinstallをしてPATHを通す installが遅すぎる!って方はこちら

qiita.com

$ $ git clone https://github.com/sstephenson/rbenv.git ~/.rbenv

環境設定の末行に追記

#~/.bash_profile

export PATH="~/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

再読込

source ~/.bash_profile

ruby_buildをインストール

$ git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
$ sudo ~/.rbenv/plugins/ruby-build/install.sh

SSL

$ sudo yum -y install openssl-devel

さぁインストール

$ yum install -y readline-devel
$ rbenv install 2.3.1
$ rbenv rehash
$ rbenv global 2.3.1

bundlerのインストール

$ gem install bundler

nginxをinstall及び設定

yum でインストールするため、yumリポジトリを登録

sudo rpm -ivh http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm

Mainlineをインストールしたいので、「/etc/yum.repos.d/nginx.repo 」を修正 stable の場合 nginx.repo は修正しなくて良いらしい。 参照:http://qiita.com/ymaru/items/4a56f1619c960981180f

# vim /etc/yum.repos.d/nginx.repo

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/6/$basearch/
gpgcheck=0
enabled=1

installする

sudo yum install nginx
#/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 unix:/var/www/#{app_name}/shared/tmp/sockets/puma.sock fail_timeout=0;
}

server {
  listen 80 default deferred;
  server_name colors-link.com;
  root /var/www/#{app_name}/current/public;
  access_log /var/www/#{app_name}/current/log/nginx.access.log;
  error_log /var/www/#{app_name}/current/log/production.log;

  location ^~ /assets/ {
    # gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @#{app_name};
  location @#{app_name} {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://#{app_name};
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

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
