導入方法
cloud9では初期状態でredisが入っているが、バージョンが2.8.4と古い。
以下のように入っているはず。
$ ll /usr/bin/red*
-rwxr-xr-x 1 root root 68272 Jan 14 2014 /usr/bin/redis-benchmark*
-rwxr-xr-x 1 root root 10464 Jan 14 2014 /usr/bin/redis-check-aof*
-rwxr-xr-x 1 root root 22760 Jan 14 2014 /usr/bin/redis-check-dump*
-rwxr-xr-x 1 root root 103008 Jan 14 2014 /usr/bin/redis-cli*
lrwxrwxrwx 1 root root 12 Jan 14 2014 /usr/bin/redis-sentinel -> redis-server*
-rwxr-xr-x 1 root root 635248 Jan 14 2014 /usr/bin/redis-server*
最新版（今日時点では4.0.1）のredisの導入方法は割合と安定していて、
テストを省くと以下のコマンドを叩くだけで良い。
wget http://download.redis.io/redis-stable.tar.gz
tar xzvf redis-stable.tar.gz
rm redis-stable.tar.gz
cd redis-stable/
make
sudo make install
そして、以下のようにして、/usr/bin/以下を最新版に取り替えることもできる。
mv redis.conf ../
cd src
sudo cp -rf redis-server /usr/bin
sudo cp -rf redis-cli /usr/bin
sudo cp -rf redis-check-aof /usr/bin
sudo cp -rf redis-benchmark /usr/bin
sudo cp -rf redis-check-rdb /usr/bin
sudo rm /usr/bin/redis-check-dump
cd ../..
cp redis.conf my.conf
rm -rf redis-stable/
こうなる。
$ ll /usr/bin/red*
-rwxr-xr-x 1 root root 2548702 Sep 17 10:33 /usr/bin/redis-benchmark*
-rwxr-xr-x 1 root root 5938969 Sep 17 10:33 /usr/bin/redis-check-aof*
-rwxr-xr-x 1 root root 5938969 Sep 17 10:33 /usr/bin/redis-check-rdb*
-rwxr-xr-x 1 root root 2729222 Sep 17 10:33 /usr/bin/redis-cli*
lrwxrwxrwx 1 root root 12 Jan 14 2014 /usr/bin/redis-sentinel -> redis-server*
-rwxr-xr-x 1 root root 5938969 Sep 17 10:33 /usr/bin/redis-server*
※上書きでもディスクスペースが消費されるから、上書きすべきかどうかはさておいて
※cloud9上でクラスタリングなどしないだろうからredis-sentinelは放置。
起動。

Redis must be restarted after THP is disabled.

おまけ /usr/bin以下を見てみる。
cloud9では、初期状態で/usr/bin以下に沢山のツール類が入っている。私の環境ではこうだった。
python3もバージョン3.4なら使えるんだな。
redisでお試ししてみたように、sudoerになれば、これらにツールを上書きすることもできる。
開発環境お試し向けに向いているcloud9らしい。
