本人機(jī)子為ubuntu。所以安裝比較簡(jiǎn)單

sudo apt-get install openssl

sudo apt-get install erlang下載deb包安裝

wget -c http://s3.amazonaws.com/downloads.basho.com/riak/2.0/2.0.2/ubuntu/trusty/riak_2.0.2-1_amd64.deb

dpkg -i riak_2.0.2-1_amd64.deb

就此安裝完成。喜歡用源碼安裝的同學(xué)也請(qǐng)考慮上面的依賴。不難，只不過可能有點(diǎn)麻煩。

啟動(dòng)riak服務(wù)

sudo riak start

具體的配置文件請(qǐng)看

/etc/riak/riak.conf

http默認(rèn)的監(jiān)聽端口為

127.0.0.1:8098

因?yàn)槭堑谝黄?#xff0c;所以暫時(shí)使用單節(jié)點(diǎn)，講解簡(jiǎn)單的操作。

添加

curl -i -H "Content-Type: plain/text" -d "Some text" http://localhost:8098/riak/foo返回：

HTTP/1.1 201 Created

Vary: Accept-Encoding

Server: MochiWeb/1.1 WebMachine/1.10.5 (jokes are better explained)

Location: /riak/foo/86qDc77dbesWX651mgSYKLqSDSW

Date: Mon, 12 Jan 2015 15:10:58 GMT

Content-Type: plain/text

Content-Length: 0上面使用的是hash key。當(dāng)然，我們可以使用指定的key:

curl -i -d '{"name":"Bruce"}' -H "Content-Type: application/json" http://localhost:8098/riak/artists/Bruce返回：

HTTP/1.1 204 No Content

Vary: Accept-Encoding

Server: MochiWeb/1.1 WebMachine/1.10.5 (jokes are better explained)

Date: Mon, 12 Jan 2015 15:22:23 GMT

Content-Type: application/json

Content-Length: 0觀察可以看到如果我們存儲(chǔ)文本成功的時(shí)候返回的代碼為201.存儲(chǔ)對(duì)象成功的時(shí)候返回的是204 No Content。另外值得注意的地方還有Content-Type.通過修改Conten-Type,我們可以存儲(chǔ)圖像等其他mime類型消息。

查詢

curl -i http://localhost:8098/riak/artists/Bruce返回：

HTTP/1.1 200 OK

Content-Length: 0刪除了之后再去Get得到的是404

riak的基礎(chǔ)操作介紹的差不多了。作為一個(gè)web開發(fā)者，感嘆其實(shí)現(xiàn)的RESTful如此優(yōu)雅。
