(Linux repositoryにissue立てるのどうかと思うけど)

https://github.com/shari-sushi/V-Kara-Lists を立てる。

dockerは使わない
1 VMに3つのインスタンスを立てる(front, back, db)

LinuC向けに GCE でインスタンス立てたときのメモ e2 コアとメモリの非？ E2, N1, N2 か業務ならC3?

名前 : 立てたいインスタンス名リージョン、ゾーン ; アイオワ、use-central マシンの構成 : E2、プリセット : e2-micro, 可用性ポリシー : スポット (真面目にサービスするなら標準)

マシン側とgcp側の両方 gcloud っていうCLI?があって、ssh接続できる。鍵使わなくてもいける？ (Cloud Shellのことと思われる)

cloud shell はユーザーごとに１つ割り当てられるマシンで動く、完全。

gcloud compute ssh [インスタンス名] --zone us-central1-c compute = サービス名(GC compute) であり、アクセス先を示している。 gcloud サービス名(アクセス先) 実行内容 us-centralが一番安そう。jpに比べて多少ラグはあるけど。

[自分のアカウント情報]:~ ([会社の情報的な])$ gcloud compute ssh [インスタンス名] --zone us-central1-c

VM作って

ボツ

## SSH接続 ### ssh鍵発行 https://qiita.com/bo_yakitarako/items/08e2d205ca7634cd7d57 > The key's randomart image is: の結果は無事表示された。鍵ができた事確認 ```sh > ls ~/.ssh ディレクトリ: C:\Users\user name\.ssh Mode LastWriteTime Length Name ---- ------------- ------ ---- -a---- 2024/05/02 18:55 2610 id_rsa -a---- 2024/05/02 18:55 578 id_rsa.pub -a---- 2024/04/22 2:47 1497 known_hosts ``` 安全にssh key作るなら{こっち](https://qiita.com/suthio/items/2760e4cff0e185fe2db9) このssh公開鍵をGCに登録する。

せっかくなのでvim使いたい→諦めた

(指定のフォルダをeditorで開きに行くより、今開いてるVScodeなりのターミナルでさくっと vim ~/.sshしたい) vim公式って誘導されたgithubが200弱のいいねしかなかったりで怖かったので断念。他の紹介サイトもzipファイルを直接ダウンロードとかで怖い。この辺り役立つかなぁ https://qiita.com/hikaruright/items/b415d569b5bbeaf967bd#homebrewの代替を探す以上。

### 既存鍵の使用 GC上にSSH鍵が書いてあるところが２か所ある。(組織所属だから?) - VMインスタンスのSSH 認証鍵の欄に`ecdsa-sha2-nistp256`, `ssh-rsa`の2種類 (`-----BEGIN OPENSSH PRIVATE KEY-----`みたいな書き方はしてない。) `ssh-rsa`の方を試してみたけど ```sh > ssh 34.172.125.65 -i ~/.ssh/hoge.pub [user]@"[インスタンスの公開IP]": Permission denied (publickey). ``` となった。(.pubの拡張子を消したりもした) - CEの[メタデータ](https://console.cloud.google.com/compute/metadata?resourceTab=sshkeys&project=portal-key-390113)の`SSH 認証鍵の欄`から自分の`ユーザー名`のキーをコピー、手元でファイルにして↑と同じようにやるも同じ結果。じゃあ手元で作成したsshキーをGCに登録しようかと思ったところ、 Google Cloud : [VM に SSH 認証鍵を追加する](https://cloud.google.com/compute/docs/connect/add-ssh-keys?hl=ja#rest) > 注意: メタデータで SSH 認証鍵を管理すると、プロジェクトメンバーが VM に接続できなくなる場合があります。また、プロジェクト外のユーザーを含むユーザーに VM への意図しないアクセス権を付与するリスクがあります。プロジェクトメタデータを変更できるユーザーとサービスアカウントは、プロジェクトレベルの SSH 認証鍵をブロックする VM を除く、プロジェクト内のすべての VM の SSH 認証鍵を追加できます。詳しくは、[手動での鍵管理のリスク](https://cloud.google.com/compute/docs/instances/access-overview?hl=ja#risks)をご覧ください。一旦ssh諦めます。また、AWSのssh接続では`-----BEGIN OPENSSH PRIVATE KEY-----`で始まる.pemを使ってたのでちょっと不思議。どっちでもいいのか。AWSの方が珍しいのかな。 (もしかしてファイアウォールで穴開けてないから？) --- ↑諦めたのでブラウザで接続する。 VMインスタンスにて、下画像のブラウザでウィンドウを開く、でブラウザでかってにSSH接続してくれるみたい。

難なくできた。 ### ファイアウォール設定 https://console.cloud.google.com/net-security/firewall-manager/firewall-policies/list?project=portal-key-390113 にて名前 : shari-v-kara 説明 : 何かあれば確認せず消してください(要約) ログ : オフネットワーク : デフォルト優先度 : `60000` トラフィック : 上り一致したときのアクション : 許可ソースフィルタ : IPv4 範囲送信元 : `[自分のpc?]/32` /32にすることでサブドメインまで許されるらしい。 (自分のPCのサブドメインってなんだ) 一致したときのアクション : 許可プロトコルとポート : TCP : ポート ; `22, 80, 443, 3306` …ファイアウォールってVMインスタンス毎じゃなくてプロジェクト毎の設定？ならやる意味なかったかも。でもdefaultが残ってたしそんな訳ないと思うんだけど…。誰かのブログ : [Compute Engine にデプロイ](https://cloud.google.com/build/docs/deploying-builds/deploy-compute-engine?hl=ja)

インスタンス作成時にHTTP, HTTPSのファイアウォールオンにしておけばひもづけられたんじゃね？立てた後でオン/オフ変更できるのだろうか。

色々やり直そう

VM編集、SSH鍵作成からやり直し

VScode　ターミナルで

> ssh-keygen -t rsa -b 4096 -f gc_v_kara
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in gc_v_kara.
Your public key has been saved in gc_v_kara.pub.
The key fingerprint is:
SHA256: ***
The key's randomart image is:
+---[RSA 4096]----+
|       ~略~      |
+----[SHA256]-----+

ここで生成された gc_v_kara.pubファイルの全文(SSH公開鍵)をコピー

前のコメントで作成していたVMを編集

SSH認証をオンにし、SSH認証鍵1にSSH公開鍵をペーストネットワークセンターのファイアウォールポリシーにて、前のコメントで作ってあったファイアウォール`shari-v-karaにタグ付け…ができなかったので諦め。

どういうことか分からなかったので、公式 : ネットワークタグを追加する

タグは、Compute Engine 仮想マシン（VM）インスタンスやインスタンステンプレートなどのリソースのタグフィールドに追加される文字からなる文字列です。タグは個別のリソースではないため、個別に作成することはできません。

えぇ…状況から予想はしてたけどまじか。今まで読んできた記事はどういうことだ。最近変わったのか？

ファイアウォールルールとルート

ネットワークタグを使用すると、特定のインスタンスまたは一連のインスタンスにファイアウォールルールとルートを適用できます。ターゲットタグとソースタグを使用して、特定のインスタンスに適用されるファイアウォールルールを作成します。タグを使用して、特定のインスタンスに適用されるルートを作成します。

どっちのタグをどっちに付ける？まあいいや

これでインスタンスの編集終了。したら、インスタンスのSSG認証鍵に、入力したSSH鍵は表示されたけどユーザー名が-になってる。大丈夫だろうか。

外部IPアドレスを確認したが、↓の通りSSH接続できず。

> ssh ***  -i ~/.ssh/gc_v_kara        
The authenticity of host ***(***)' can't be established.
ECDSA key fingerprint is SHA256: ***.  
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '***' (ECDSA) to the list of known hosts.
***@***: Permission denied (publickey).

> ssh ***  -i ~/.ssh/gc_v_kara.pub
***@***: Permission denied (publickey).

後日、

ssh user名@*** -i ~/.ssh/gc_v_kara.pub 的なこともしたけどだめだった

※新規IPは確認表示があり、yesする度にknown_hostsに溜まっていくので、何となく都度削除している。インスタンスは機動から12時間で自動で停止するようにしてるから。(再起動の度にpublic IP変わるから)

でも下画像からブラウザならアクセスできるんだよな。

流石にダメだった

ブラウザSSH接続で実験 ```sh > mkdir v-kara > cd v-kara > git clone https://github.com/shari-sushi/V-Kara-Lists.git -bash: git: command not found > git install -bash: git: command not found ``` 調べたらできるのかもしれないけど、それは後日。 (正しくはgit initだったけどそもそもgit command使えないっちゅう)

ブラウザからSSH接続できなくなった気がしたけど気の精だった?

ファイアウォールに新しい公開IPを…これ自分のPCのIPアドレス/32入れた気がするわ。てかいつの間にかインスタンス止まってて、再開したら接続できた。

サーバーを立てる

GCP (Google Cloud Platform) の Compute Engine で爆速で Web アプリ環境を用意する全手順

GCP でユーザ登録 ~略~

インスタンス作成 ~略~

Web サーバ導入次に、Nginx をインストールする。今回は ContOS7 に入れてるので「こちら」の記事を参考にインストールする。これで、http://外部IPアドレスにアクセスして、Web サイトが公開できた。以上で Web アプリの環境が完成した。あとは、各自のソースコードを適所にデプロイしてあげるだけ

LinuC用、v-kara用の両インスタンスにてOSの確認が取れなかった (初見の何かを選んだ気がするんだけども→多分debianだ) あった？

【第30回】DebianとUbuntu、CentOSとRHELから学ぶ、Upstreamとの関係

Ubuntuに対してDebianは「選択の自由」も重要視している。たとえばDebianはインストール時にデスクトップ環境を選択できるし、Ubuntuに比べるとサポートしているCPUアーキテクチャも多い。使用するソフトウェアを決め打ちすることで、Live環境とインストーラーを同一化させ初心者が悩まないようにしているUbuntuとは対照的だろう。

とりあえず先に進んで、ダメそうならOSが無いor不適合かもという判断をする。

CentOS7 に Nginx をインストールする

$ sudo ls /etc/yum.repos.d/nginx.repo
ls: cannot access '/etc/yum.repos.d/nginx.repo': No such file or directory
sudo vi /etc/yum.repos.d/nginx.repo

で作成、書き込みを同時にしたのに権限エラーってまじか。てか空にしても同じエラー。

E212: Can't open file for writing

↓でできた

$ mkdir  ./etc/yum.repos.d/
$ touch  ./etc/yum.repos.d/nginx.repo
$ ls  ./etc/yum.repos.d/nginx.repo
$ ls -l ./etc/yum.repos.d/
total 0
-rw-r--r-- 1 [myname] [myname] 0 May  4 06:12 nginx.repo
$ sudo vi /etc/yum.repos.d/nginx.repo

書き込んだ内容

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=0

このあとの操作。せっかくならシェルスクリプトやりたかったけど、出力を読みってwhileで回してinputを求めるor全てのinputを求めるのに自動でyesの解答するみたいなの書き方調べるのちょっと横道にそれすぎなのでやめた(言い訳)

yumは、linuxの中でも、Fedora , RedHat , CentOSなどのディストリビューションで標準として使用されるパッケージ管理ソフトです。

ですが、あなたのlinuxは恐らくDebian , Ubuntuなどのディストリビューションです。これらのlinuxでのパッケージ管理ソフトではyumではなくaptと言うパッケージ管理ソフトを使用します

https://kyoruni.hatenablog.com/entry/nginx-install どの記事見ても、install直後にそのままnginx -vしてる

ちなみにいまこんな状態

pathが通っていないのか他に理由があるのか https://atmarkit.itmedia.co.jp/flinux/rensai/linuxtips/035addnewpath.html

path通し方 https://qiita.com/ryouya3948/items/8edbd5d744c83dd41141

問題はどこに通すかなんだよな

これで親の親から探してみるかね https://www.sejuku.net/blog/54248

$ which ls
/usr/bin/ls

$ wichi nginx
-bash: wichi: command not found

etc/yum.repos.d/nginx.repoこれも怪しいよね

ls ../../usr/bin の結果、そこにnginxっぽいフォルダ、ファイルは無かった。

treeコマンド入れてみた。

【Debian】Debianでnginxをインストールして、htmlの編集をした。(公式の微解説)

⑧sudo apt update
⑨sudo apt install nginx

※丸番号は私の加筆

①
- debianでは yun ではなく apt がデフォ
- curl 他 4つのパッケージをインストール
②
- curlでgetリクエストし、受け取ったデータをパイプで渡す
- --dearmor : バイナリに変換 gpg公式に無かった
- tee : 標準出力しつつ、ファイルに書き込み。引数(ファイルpath)の数だけ書き込める。
③
- gpg
- --dry-run : 実際に実行はしない？
- --quiet : (AI「出力を最小限に抑え、エラーメッセージ以外は表示しない」) 公式の説明文↓理解不能なんだが。
  
  These options are used to change the configuration and most of them are usually found in the option file.
- --no-keyring : (Ai「既存のkeyringsを使わない」) keyrings = 鍵束 = 沢山の鍵
  
  If the option --no-keyring has been used no keyrings will be used at all.
- --import --import-options
- import-show
- /usr/share/keyrings/nginx-archive-keyring.gpg

ubuntuでした……なんで ubuntuならgitコマンド最初から打てた。 (treeはダメだった)

https://qiita.com/keitean/items/9b2284a053bc13bcdf7b

ってか、これの通り従っちゃだめか？

MySQL用意して、環境変数を渡してやればそのまま起動しそう。

$ npx

Command 'npx' not found, but can be installed with:

apt install npm
Please ask your administrator.

$ npm

Command 'npm' not found, but can be installed with:

apt install npm
Please ask your administrator.

npx,npmもインストール必要っぽい

メモ

cd  v-kara/V-Kara-Lists/t0016Go/cmd

go run .

ToDo

Go
- 同じVMインスタンス上にあるMySQLに接続できるようにする (ローカル扱いだったりする？)
- 環境変数をVMに登録
- git cloneじゃなくて直接upしたい(微修正面倒)
MySQL
- インスタンス上に構築
- この時、hostはどうなるのか
- ssh接続で接続できるか確認
Next (単純にやってよいのか？ )
- npx, npmのインストール？
- 同じVMインスタンスにあるGoへ接続できるようにする
- 環境変数をVMに登録

※環境変数ってVMインスタンス単位？それとも個別？

nginx消す。
- apt-get purgeで https://codechacha.com/ja/linux-apt-purge-vs-remove/

$ mysql -u root -p
Enter password: 
ERROR 1698 (28000): Access denied for user 'root'@'localhost'

MySQLをインストールしたときのログで気になってるのは、 mysqld is running as pid 4386 え、インストールした時点でmysqlは立ち上がってる？(プロセス扱いになってるってこと？)

プロセスの復習: https://github.com/shari-sushi/0025Linux/issues/1#issuecomment-2084858518

4.5.1.1 mysql クライアントオプション

--table, -t

出力を表形式で表示します。インタラクティブに使用する場合はこれがデフォルトですが、バッチモードで表形式の出力を生成するのにも使用できます。

https://dev.mysql.com/doc/refman/8.0/ja/problems-connecting.html

新規インストールの後、パスワードを使用せずに root としてサーバーにログオンしようとすると、次のエラーメッセージが表示されることがあります。
shell> mysql -u root 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
これは、インストール時に root パスワードがすでに割り当てられており、指定する必要があることを意味します。

つまり、今回自分のにはパスワードが必要と。でも8.0では自動生成されないみたいなことが同じ公式に書いてあったのに…。

MySQL接続

↑のコメントで

ERROR 1698 (28000): Access denied for user 'root'@'localhost'

ってなったのはやっぱlocalhost扱いになってる？

それはさておき、まずはパスワード探し https://qiita.com/RyosukeSomeya/items/c695487588f5ac28d9f4

/var/log/mysqld.log このファイルをviコマンドやlessコマンドで確認すると以下の様なログがあるはずです。 [Note] A temporary password is generated for root@localhost: Ea

親の親ディレクトリにvar/log/mysqlはあったけどmysqld.logは無かった。それ開いたけどログじゃなかった。正規表現とコマンド？オプション？が書いてあった。

わかんないからGCEのルートでgrep

grep temporary password

10分以上待っても終わらなかった…

mysql.logなさそう(色々あった)

$ ls ../../etc/my*

↓この状態で、viで開くと、以下の画像のように新規ファイルとなり、中身は空。なぜ。

:/etc$ ls my*
conf.d  debian-start  debian.cnf  my.cnf  my.cnf.fallback  mysql.cnf  mysql.conf.d
:/etc$ vi my.cnf
:/etc$ vi mysql.cnf

メモ

https://www.web-dev-qa-db-ja.com/ja/command-line/lsの色の違いは何を意味しますか？/957164827/

青：ディレクトリ緑：実行可能または認識されたデータファイルスカイブルー：シンボリックリンクファイル背景が黒の黄色：デバイスピンク：グラフィック画像ファイル赤：アーカイブファイル背景が黒の赤：リンク切れ

わわわ: シンボリックリンク

UNIX系のOS（Linuxとか）における、ファイルやフォルダの代理人ファイルのこと。

MySQL入れ直し

logファイルもない、my.cnfもない(…多分)でよくわからなかったので、入れ直し。

注: このチュートリアルでMySQLシェル内にユーザーを追加する場合、ユーザーのホストをサーバーのIPアドレスではなく、localhostとして指定します。localhostは「このコンピューター」を意味するホスト名で、MySQLはこの特定のホスト名を特別に扱います。そのホストを持つユーザーがMySQLにログインすると、Unixソケットファイルを使用してローカルサーバーに接続しようとします。したがって、通常、サーバーにSSHで接続する場合、またはローカルmysqlクライアントを実行してローカルMySQLサーバーに接続する場合に、localhostが使用されます。

※注意ユーザー作成

CREATE USER 'USER'@'IP' IDENTIFIED BY 'password';

IPについて

今回はlocalhostとした。

これはMySQLでは特に特別視されているようで、127.0.0.1とは扱いが違うらしい。何とかソケットを使って接続している…。

これがバックエンドから処理する際は、localhostと書いていても、内部処理で127.0.0.1に変換される可能性がある。その場合は、MySQL側で127.0.0.1のユーザーを作成する必要がある。

PC上やDocker上のMySQLではlocalhostで接続できていたので完全に落とし穴。

Press y|Y for Yes, any other key for No: Y There are three levels of password validation policy: LOW Length >= 8 MEDIUM Length >= 8, numeric, mixed case, and special characters STRONG Length >= 8, numeric, mixed case, special characters and dictionary file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0 Skipping password set for root as authentication with auth_socket is used by default. If you would like to use password authentication instead, this can be done with the "ALTER_USER" command. See https://dev.mysql.com/doc/refman/8.0/en/alter-user.html#alter-user-password-management for more information. By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y Success. All done! ```

環境変数を設定するだけで済むと思うけど、ネットで調べるとDocker前提の話ばかり出てくる。会社ではCloud Runつかってるぽいけど…？ https://zenn.dev/nananaoto/articles/c56bc2b38834b32c8fd7#%E3%83%AD%E3%83%BC%E3%82%AB%E3%83%AB%E3%81%8B%E3%82%89cloud-build%E3%82%92%E5%AE%9F%E8%A1%8C

今日中にデプロイして動作確認する(curl可)という目標ができたので、ハードコードすれば何とかなることは後回し。
