–webroot などをガン無視。www.c-anemone.tech が作れなかったけど、こっちも無視。

でもって、

ubuntu@ip-172-26-13-137:~/go_template/server_test$ sudo cp /etc/letsencrypt/live/c-anemone.tech/fullchain.pem .
ubuntu@ip-172-26-13-137:~/go_template/server_test$ sudo cp /etc/letsencrypt/live/c-anemone.tech/privkey.pem .

を強行。

privkey.pemの権限が厳しいので、危ないけど >chmod +777 privkey.pem をやって、golangからアクセスして貰えるようにしておいた(権限のモードを忘れた)

で、serverXX.goの中を書き換え

/*
                log.Fatal(http.ListenAndServe(*addr, nil)) // localhost:8080で起動をセット
        */

        /*
        var httpErr error
        if _, err := os.Stat("./algo.crt"); err == nil {
                fmt.Println("file ", "algo.crt found switching to https")
                if httpErr = http.ListenAndServeTLS(*addr, "./algo.crt", "./algo.key", nil); httpErr != nil {
                        log.Fatal("The process exited with https error: ", httpErr.Error())
                }
        } else {
                httpErr = http.ListenAndServe(*addr, nil)
                if httpErr != nil {
                        log.Fatal("The process exited with http error: ", httpErr.Error())
                }
        }
        */

        var httpErr error
        if _, err := os.Stat("./fullchain.pem"); err == nil {

                if httpErr = http.ListenAndServeTLS(*addr, "./fullchain.pem", "./privkey.pem", nil); httpErr != nil {
                        log.Fatal("The process exited with https error: ", httpErr.Error())
                }
        } else {
                httpErr = http.ListenAndServe(*addr, nil)
                if httpErr != nil {
                        log.Fatal("The process exited with http error: ", httpErr.Error())
                }

としたら、とりあえず

https://sea-anemone.tech:8080

で、iPadに地図が表示されるのは確認できた。

今日はここまで。

 

 

2020/10,江端さんの技術メモ

PruneMobile  を Amazon Lightsail に乗せています。

https://が上手く起動しなかったので、色々考えていました。

まず、serverXX.goを、

//var addr = flag.String("addr", "0.0.0.0:8080", "http service address") // ローカルテスト
var addr = flag.String("addr", ":8080", "http service address") // AWS上で動かす時

と変更して、さらに、これまで使ってきた「オレオレ証明書」の内容に問題があると気がついて、mkcert を使って、AWS Lighsail対応に作り直してみました。

C:\Users\ebata\Downloads>mkcert-v1.4.1-windows-amd64.exe sea-anemone.tech 43.53.5.81 137.172.25.12 localhost 127.0.0.1
Using the local CA at "C:\Users\ebata\AppData\Local\mkcert" ✨

Created a new certificate valid for the following names 📜
 - "sea-anemone.tech"
 - "43.53.5.81"
 - "137.172.25.12"
 - "localhost"
 - "127.0.0.1"

The certificate is at "./sea-anemone.tech+4.pem" and the key at "./sea-anemone.tech+4-key.pem" ✅

で、"sea-anemone.tech+4.pem"を"algo.crt"と、"./sea-anemone.tech+4-key.pem" を"algo.key"とリネームして、serverXX.goの入っているディレクトリに放り込みました。

WindowsPCの方は、上手く表示できるのですが、iPhoneやiPadの方は、

ERROR:undefined
onclise:CLOSE

が表示されて、JavaScriptが走りません。

分からないのですが『さすがに、iPhoneは「オレオレ証明書」では騙せないのかな』などと考えています。

Amazonの証明書は無料なのですが、なぜかAmazonの証明書はロードバランサがないと使えず、そんでもってロードバランサは$18/monthも金を取られるんです。本体が$3.5/monthなのに、なんか理不尽です。

とすると、アレかなぁ・・・できるだけ手を出したくないんだけどなぁ。

ともあれ、今日は疲れましたので、終了です。

2020/10,江端さんの技術メモ

Amazon Web Service(AWS)の無料期間が経過していて、3~4回くらい、5000円/月の課金を喰らっていたことを知って、先日あわててアカウントを抹消しました。

# 練習用に使っていただけなに、バカみたいです。

ところで、私が今、個人のWebサイトで利用させて頂いているのは、さくらインターネットの月額500円の仮想サーバです。WordPressと併用できて、とても便利です。

ただ、以前、このサーバを使って実家監視システムを作ろうと思ったのですが、色々問題があって使えませんでした(ホームページ用の仮想サーバなんだから当り前)。

といって、AWSは、高額の上に設定が面倒。このクラウドに、どれだけの時間を持っていかれたことか

という訳で調べたら、Amazonにも3.5ドル/月のサーバがあることが分かりました。 Amazon Lightsail です。

うん、これ、いい。私は、サーバを攻撃から守る気もないし、システム破られて持ち出された情報なんぞ入れる気もない。EC2なんぞ1つあれば十分だし、DBはUbuntuの中に作りこんでしまえばいい。

そもそも、ファイアウォールとして使っているロードバランサの設定も、Route53の設定もやりたくありません。

という訳で忘れない内にAmazon Lightsail の作成手順をメモしておきます。

(1)AWSのアカウントを作成(省略)

(2)Amazon Lightsail を選んで、「インスタンスの作成」ボタンを押下

私は、Ubuntu20.04を選択

一番安い$3.5を選択

あとは、ほったらかしにして(入力値はデフォルト、タグは無視)「インスタンスの作成」ボタンを押下

で、「データベース」タブは無視して、「ネットワーキングタブ」を選択

「静的IPの作成」ボタンを押して、そのままIPアドレスを作る。ちなみに、pingでは応答しないようです。

次に「DNSゾーン」の作成ですが、私は、お名前.comに1つドメイン名を確保しているので、それを使うことにしました。

そのやり方については、これを参考にして下さい。

基本的には、この情報を、お名前.comの方に書き込むだけです。

DNSレコードは、Aレコードだけを設定すれば良いです(サブドメインを作りたい場合は別)。

結果として、こんな表示が出せれば正解

DNSの反映されるに、10分~20分ってところだったと思います。

それと、どこでやったか忘れてしまったけど、SSHアクセス用の秘密鍵をダウンロードするプロセスがでてくるので、それをダウンロードしておく。LightsailDefaultKey-ap-northeast-1.pem てな名前でした(ダウンロード後、リネームしておくと良いでしょう)。

それを使ってTeraTermで、カーネルにアクセスできるようになります。FTPもteratermから “ファイル" → “SSH SCP"を選ぶと、ファイル転送できます(FFFTPは使えません)

あとは、TeraTermでSSHログインして、こんなコマンド投入しておきました。

>sudo apt-get update
>sudo apt install net-tools
>sudo apt install emacs
>sudo apt install golang-go

ロードバランサを使うと$18/月も取られるようなので、OS剥き出しで運用することにしました。

ポートのオープンはこちらからできます。ローカルのテストで http://localhost:8080 とかを使っていましたので、以下のように8080をオープンしておきます。これで、http://sea-anemone:8080 とかが使えるようになります。

(因みに、IPアドレスはデタラメな値に差し替えています)

なお、go言語で作っているサーバの方ですが、以下のような書き換えだけで対応できるようです。

//var addr = flag.String("addr", "localhost:8080", "http service address") // これは動かない
//var addr = flag.String("addr", "0.0.0.0:8080", "http service address") // ローカルでの環境
var addr = flag.String("addr", ":8080", "http service address") // AWS lightsailでの環境

 

2020/10,江端さんの技術メモ

document.getElementById(“open").onclick = function(evt) と、ws.onopen = function(evt) が、混乱して、上手く動かなかったけど、ようやく分かりました(ような気ががしています)。

■document.getElementById(“open").onclick = function(evt) { 処理内容}は、
“open"ボタンを押した時に行う処理を行い、
■ws.onopen = function(evt){処理内容}は、
websocketのopenのイベントが飛んできた時に行う

つまり、"ボタン"と"websocket"という、全く別物を取り扱っている、ということに、やっと気がつきました ―― 同じ"open"という言葉を使うので、混同していました。

なので、

ws.close()処理は、当然に、document.getElementById(“open").onclick = function(evt) { 処理内容} の中で実施しなけばなりません。

ws.onopen = function(evt){処理内容}は、すでにwebsocketのclose処理が行われた後の処理を記載するので、ここでws.close()を記載したら、変なことになります(二重にwebsocketのclose処理をすることになる)


 

それと、位置情報をコールバックで取得する関数を、
const successCallback = (position) => { 処理内容 }

エラーイベントを検知する関数を、
const errorCallback = (err) => { 処理内容 }
と記載した場合、

このコールバックを登録する関数は、
watchPositionID = navigator.geolocation.watchPosition(successCallback, errorCallback, options);
であり、

このコールバックを停止する関数は、navigator.geolocation.clearWatch(watchPositionID);

となります。

という訳で、server26.goの"smartphoneTemplate"で登録している、htmlファイル(javascriptを含む)の部分だけ切り出したものを記載しておきます。

var smartphoneTemplate = template.Must(template.New("").Parse(`

人間は、他人を他人として認識するのではなく、その他人の属する所属や地位、環境を含めて認識します。

Humans don’t perceive others as others but others including their affiliations, status, and environments.

「部長の山田さん」「新人の田中さん」「技術者の佐藤さん」「ドイツ在住の高橋さん」等々です、

Mr. Yamada, the department head, Ms. Tanaka, the new guy, Mr. Sato, the technician, Ms. Takahashi, who lives in Germany, and so on.

特に初対面の場合は、そうなるのは仕方がありません。

Especially in the case of the first meeting, it can not be helped.

その時の私たちは、他人を評価する情報を全く持っていないからです。

At that time, we have no information to evaluate others.

—–

ただ、「名物研究員の江端さん」というフレーズには、所属、地位、環境を含んでいません。

However, the phrase “Mr. Ebata, a famous researcher" does not include affiliation, position, or environment.

そこには、敬意とも蔑視とも解釈可能な「形容句」が入っているだけです。

It only contains “adjectives" that can be interpreted as both respect and contempt.

先日も、メールの中にこのフレーズを見つけて、『なるほど、私は"名物研究員"なんだ』と認識しました。

The other day, I found this phrase in an email and realized that “I see, I’m a famous researcher".

—–

「こちらが、同じ部署の江端です」という同僚の紹介で、先方の方と名刺交換をしている時に、

When I was exchanging business cards with the other person, I was introduced by a colleague who said, “This is Ebata from the same department."

『ああ、こちらが、あの江端さん・・・、お噂はかねがね伺っております』

“Oh, You are Mr. Ebata… I’ve heard a lot of great things about you."

というコメントを頂きました。

I got the comment.

—–

―― “ソースは誰?"

“Who is the source ?"

―― “どんな噂?"

“What kind of great things ?"

と、突っ込みたくなっても、苦笑いしながら、それを、グっと我慢するのが、

Even if I want to dig in, I have to put up with it with a bitter smile.

「大人の社会人」というものです。

This is an “adult business people"

木材から円形(円盤)を切り出すことが必要となり、色々試しています。

このような、電動ドライバーに装着できる、木材用の円切りサークルカッターを使っていました。

しかし、これで作業すると、直径20cmの円を切り出すのに、(慣れてきても)10分以上はかかるので、非常に効率が悪く、恐しく疲労します。

そこで、今回、BOSCH(ボッシュ)の電動ノコギリを使って木板を円形に切ることのできる、BOSCHのジグソー円曲平行ガイドを購入しました(別の会社の電動ノコギリの場合、その会社が提供しているものを購入する方が安全です)

先程、自宅に届いたので、さっそく、自分のメモとしてジグソー円曲平行ガイドを、袋から取り出すところから、切り出すまでの全行程を撮影しました。

 

映像の中では、キレイな円形の切出しに失敗していますが、これは中心線をズラさないようにすれば、必ず成功しますので御安心下さい。

サークルカッターと比較して、もの凄くラクチンに円盤を切り出せました。

スマホから位置情報を取得するところまできたが、https(wss)対応にしないと位置情報が取り出せないようです(かなりしつこく聞いていましたが、すっかり忘れていました)。

で、今のGolangのサーバプログラムをhttps対応にすべく、色々試したのですが、なんかこれで動いているようなので、要点だけ記載します。

Step.1 

まず、

C:\Users\ebata\WssSample\goClient>go run goClient.go conn.go hub.go tls: first record does not look like a TLS handshake がなんともならない件

の、mkcertを使って生成した鍵(“algo.key"と"algo.crt")をディレクトリに放り込む

Step.2

serverXX.goの、サーバ作成部を以下のように変更する

/*
		log.Fatal(http.ListenAndServe(*addr, nil)) // localhost:8080で起動をセット
	*/

	var httpErr error
	if _, err := os.Stat("./algo.crt"); err == nil {
		fmt.Println("file ", "algo.crt found switching to https")
		if httpErr = http.ListenAndServeTLS(*addr, "algo.crt", "algo.key", nil); httpErr != nil {
			log.Fatal("The process exited with https error: ", httpErr.Error())
		}
	} else {
		httpErr = http.ListenAndServe(*addr, nil)
		if httpErr != nil {
			log.Fatal("The process exited with http error: ", httpErr.Error())
		}
	}

Step.3

htmlファイルの、"http://"を、片っ端から"https://"に書き換える。

さくっと動いて気持ち悪いのですけど、まあ動くのであれば、なんでも良いです。

RUN add-apt-repository ppa:bitcoin/bitcoin を ppa:luke-jr/bitcoincore に変更してみたら、Dockerfileが通った

 

 

ターミナルを開いて、コンテナに入ります。
docker exec -it bitcoin_1 /bin/bash
 root@bitcoin_1:/# bitcoind -daemon Bitcoin Core starting root@bitcoin_1:/# bitcoin-cli generate 100 error code: -32601 error message: Method not found

あれ?

bitcoin-cli getinfoで確認出来るって書いてたけど、もう無くなったAPIになっちゃてたみたい

This command doesn’t exist anymore since Bitcoin Core 0.19. Use generatetoaddress instead. てなことが記載されている。

ここを読んでみると、

Generate 11 blocks to myaddress
> bitcoin-cli generatetoaddress 11 "myaddress"
If you are running the bitcoin core wallet, you can get a new address to send the newly generated bitcoin to with:
> bitcoin-cli getnewaddress

てな記載がある。

とにかくブロックを作らんことには、金(ビットコイン)が稼げないが、上記の"myaddress"が何ならよう分からん。

ここ の記事にある、bitcoin-cli generatetoaddress 101 `bitcoin-cli getnewaddress`

をやってもいいものなのか?

ちなみに、bitcoin-cli getnewaddress を実行すると、

root@bitcoin_1:/# bitcoin-cli getnewaddress
bcrt1qymag0kvldyw4saejksnssv92ss3awrkp5vz6ef

てな内容が出てくる(アドレス、モロばれだけど、実際の環境では使わないからいいかな)

で、やってみた。

root@bitcoin_1:/# bitcoin-cli generatetoaddress 101 `bitcoin-cli getnewaddress`

うん、なんかブロックできたみたいだ。

うん、できている。では金額を確認してみよう。

root@bitcoin_1:/# bitcoin-cli getbalance
50.00000000

おお! 凄い。今1BTCが120万円くらいだから、6000万円を作ってしまったぞ! 

では、ここで口座(アカウント)を作ってみよう。

bitcoin-cli getnewaddress testuser1

でもって、残高を調べるけど・・・
