簡(jiǎn)介

FoudationDB是蘋(píng)果公司近期開(kāi)源的一款分布式，支持事務(wù)型的key-value數(shù)據(jù)庫(kù)。

安裝

• 準(zhǔn)備A,B兩臺(tái)在同一網(wǎng)段內(nèi)的Ubuntu服務(wù)器(我用了兩個(gè)ECS)
• 下載安裝Server , Client 和 Python版的API

$ wget https://www.foundationdb.org/downloads/5.1.7/ubuntu/installers/foundationdb-clients_5.1.7-1_amd64.deb
$ wget https://www.foundationdb.org/downloads/5.1.7/ubuntu/installers/foundationdb-server_5.1.7-1_amd64.deb
$ wget https://www.foundationdb.org/downloads/5.1.7/bindings/python/foundationdb-5.1.7.tar.gz
$ sudo dpkg -i foundationdb-server_5.1.7-1_amd64.deb foundationdb-clients_5.1.7-1_amd64.deb
$ tar -zxf foundationdb-5.1.7.tar.gz 
$ cd foundationdb-5.1.7 && python setup.py install

此時(shí)AB之間不能相互訪問(wèn)，需要配置cluster

• 配置訪問(wèn)權(quán)限
  1. 配置B機(jī)器使其對(duì)外可用

  $ sudo /usr/lib/foundationdb/make_public.py
  /etc/foundationdb/fdb.cluster is now using address 172.17.xxx.xxx
  

  2. 將B的配置文件 /etc/foundationdb/fdb.cluster 覆蓋掉A的配置后重啟A的服務(wù)

  $ sudo service foundationdb restart
  

測(cè)試

• 在B機(jī)器中寫(xiě)入一個(gè)key-value

$ python
>>> import fdb
>>> fdb.api_version(510)
>>> db = fdb.open()
>>> db['hello'] = 'world'
>>> db['hello']
'world'

• 在A機(jī)器中讀取

$ python
>>> import fdb
>>> fdb.api_version(510)
>>> db = fdb.open()
>>> db['hello']
'world'

• 在A機(jī)器中寫(xiě)入一個(gè)key-value

>>> db['hi'] = 'foundationDB'
>>> db['hi']
'foundationDB'

• 在B機(jī)器中讀取

>>> db['hi']
'foundationDB'
