FoundationDB
FoundationDB是Apple维护的NoSQL资料库。
安装
在Ubuntu下可以使用官方打包好的deb安装7.1版：
cd /tmp; wget -c https://github.com/apple/foundationdb/releases/download/7.1.65/foundationdb-clients_7.1.65-1_amd64.deb; sudo dpkg -i foundationdb-clients_7.1.65-1_amd64.deb; wget -c https://github.com/apple/foundationdb/releases/download/7.1.65/foundationdb-server_7.1.65-1_amd64.deb; sudo dpkg -i foundationdb-server_7.1.65-1_amd64.deb
也可以安装7.3版，但我无法跑起cluster模式：
cd /tmp; wget -c https://github.com/apple/foundationdb/releases/download/7.3.43/foundationdb-clients_7.3.43-1_amd64.deb; sudo dpkg -i foundationdb-clients_7.3.43-1_amd64.deb; wget -c https://github.com/apple/foundationdb/releases/download/7.3.43/foundationdb-server_7.3.43-1_amd64.deb; sudo dpkg -i foundationdb-server_7.3.43-1_amd64.deb
设定
Cluster
这边假设有三台机器，先把FoundationDB跑在Public Interface上（预设会跑在127.0.0.1上）：
sudo python3 /usr/lib/foundationdb/make_public.py
sudo service foundationdb restart
测试
先进入CLI介面：
fdbcli
在CLI的预设是唯独模式，透过指令允许送出写入操作：
writemode on
接著可以进行操作：
get a/b/c
set a/b/c foo
get a/b/c
clear a/b/c
get a/b/c
