Ubuntu20.04に最新のNginxをインストール

Last updated at Posted at 2022-03-16

UbuntuにStable版の最新Nginxをインストールしたので備忘録です。

参考

Nginxの公式サイトの手順(トップページ > download > Pre-Built Packages に記載のリンク)そのままです。

前提条件

Ubuntu 20.04 (AWS EC2)

手順

  1. 必要なものをインストール

    $ sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring
    
  2. 署名キー取得

    $ curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
        | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
    
  3. 公式サイトにあるお手本通りの出力であることを確認

    $ gpg --dry-run --quiet --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg
    (前略)
    pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
          573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62
    uid                      nginx signing key <signing-key@nginx.com>
    
  4. リポジトリを設定(stable版)※mainline版はURLが異なる

    $ echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
    http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
        | sudo tee /etc/apt/sources.list.d/nginx.list
    
  5. nginx.listに記載されていることを確認

    $ cat /etc/apt/sources.list.d/nginx.list
    deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/ubuntu focal nginx
    
  6. リポジトリのピン止め

    $ echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
        | sudo tee /etc/apt/preferences.d/99nginx
    
  7. 更新、バージョン確認、インストール

    $ sudo apt update
    $ sudo apt info nginx
    Package: nginx
    Version: 1.20.2-1~focal
    (後略)
    $ sudo apt install nginx
    

インストールできるとこんな感じのメッセージが表示される!

起動

起動コマンドsudo systemctl start nginxでエラーがでたので、一度Ubuntuを再起動してから再確認したらOKだった
