Conoha上でHyperledger Fabricをビルドするまで #Blockchain

サーバはUbuntuで、メモリ１GBのプランでも行けます。
基本的にはこちらのページを参照。

hyperledger/fabricをEC2で動かす
 (Qiita版)
ただし、

Install rocksdbの部分で、swapの設定はたぶん不要（省略）
チャレンジャーなので一つ前のもの(v4.5.1)ではなくmasterを入れてみた。
git clone https://github.com/facebook/rocksdb.git
make static_lib

そしてmakeして待つこと数分・・・

・・・ですよねー。　ということでググる。

Fabric on RHEL 6 #2098

This is the workaround I have used. Unzip into >/src/github.com/hyperledger/fabric/vendor/github.com/tecbot/gorocksdb

The commented out APIs don't seem to be used anywhere in hyperledger.

workaround.zip

このworkaround.zipとやらには、options_compression.go、options.go という2つのファイルが入っていたので、言われたとおりfabric/vendor/github.com/tecbot/gorocksdbの下に上書きコピー。

たぶんうまくいったっぽい。

このままだと、世界中どこからでもAPIをたたけてしまう＝誰でもchaincodeをデプロイできちゃうので、FW設定をしようと

$ sudo ufw enable

したら、、、そのままコンソールが帰ってこなくなった・・・・・。

あわててconohaコンソールから

# ufw allow 22

して復活。
