Redis叢集方案，Codis安裝測試
1，關於豌豆莢開源的Codis
Codis是豌豆莢使用Go和C語言開發、以代理的方式實現的一個Redis分散式叢集解決方案,且完全相容Twemproxy。Twemproxy對於上一層的應用來說, 連線Codis Proxy（Redis代理服務）和連線原生的Redis伺服器沒有明顯的區別,上一層應用能夠像使用單機的 Redis一樣對待。Codis底層會處理請求的轉發、不停機的資料遷移等工作, 所有底層的一切處理, 對於客戶端來說是透明的。總之，可以簡單的認為後臺連線的是一個記憶體無限大的Redis服務。Codis遵循MIT開源協議釋出，更多關於Codis的資訊請登入其在GitHub的主頁檢視。
Codis 是一個分散式 Redis 解決方案, 對於上層的應用來說, 連線到 Codis Proxy 和連線原生的 Redis Server 沒有明顯的區別 (不支援的命令列表), 上層應用可以像使用單機的 Redis 一樣使用, Codis 底層會處理請求的轉發, 不停機的資料遷移等工作, 所有後邊的一切事情, 對於前面的客戶端來說是透明的, 可以簡單的認為後邊連線的是一個記憶體無限大的 Redis 服務.
Codis 由四部分組成:
Codis Proxy (codis-proxy)
Codis Manager (codis-config)
Codis Redis (codis-server)
ZooKeeper

Redis 3.0 rc4已經發布了，也是一種方案可以研究下，線上系統不建議使用。
2，安裝Codis&配置
參考文件：
https://github.com/wandoulabs/codis/blob/master/doc/tutorial_zh.md#build-codis-proxy–codis-config
首先按照golang，下載地址：https://golang.org/dl/，最新的1.4.2版本。
如果被牆使用golang中國下載http://golangtc.com/download。

安裝codis，需要下載依賴包。比較慢，依賴

安裝測試成功，就可以配置了。
編譯後的二進位制檔案在/usr/local/codis/bin目錄下面。
啟動codis之前需要安裝zookeeper。
下載地址：http://zookeeper.apache.org/releases.html#download
安裝目錄/usr/local/zookeeper
<code class="hljs perl has-numbering"><span class="hljs-keyword">mkdir</span> /usr/<span class="hljs-keyword">local</span>/zookeeper/logs</code><ul style="display: block;" class="pre-numbering"><li>1</li></ul>
vi /usr/local/zookeeper/conf/zoo.cfg配置檔案
<code class="hljs ruby has-numbering">tickTime=<span class="hljs-number">2000</span> clientPort=<span class="hljs-number">2181</span> dataDir=<span class="hljs-regexp">/usr/local</span><span class="hljs-regexp">/zookeeper/data</span> dataLogDir=<span class="hljs-regexp">/usr/local</span><span class="hljs-regexp">/zookeeper/logs</span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li></ul>
啟動zookeeper
<code class="hljs lua has-numbering">sh /usr/<span class="hljs-keyword">local</span>/zookeeper/bin/zkServer.sh start</code><ul style="display: block;" class="pre-numbering"><li>1</li></ul>
啟動Codis服務，之前必須啟動zookeeper，sample目錄有簡單的叢集配置。
startall.sh指令碼會同時將redis啟動。
<code class="hljs sql has-numbering"># sh /usr/local/codis/sample/startall.sh

啟動之後就可以看到zookeeper裡面的資料了。
<code class="hljs sql has-numbering">[zk: localhost:2181(CONNECTED) 8] ls /zk/codis/db_test [migrate_manager, fence, migrate_tasks, <span class="hljs-operator"><span class="hljs-keyword">LOCK</span>, slots, actions, servers, proxy]</span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li></ul>

啟動之後就可以訪問admin頁面了。

4，總結
Codis可以完美的解決Redis叢集問題，在目前Redis 3.0版本還不是很穩定的情況下，是非常不錯的解決方案。支援資料擴充套件。
但是並不是所有的redis命令都支援。
如果你使用以下命令:
<code class="hljs sql has-numbering">KEYS, MOVE, OBJECT, <span class="hljs-operator">RENAME, RENAMENX, SORT, SCAN, BITOP,MSETNX, BLPOP, BRPOP, BRPOPLPUSH, PSUBSCRIBE，PUBLISH, PUNSUBSCRIBE, SUBSCRIBE, UNSUBSCRIBE, DISCARD, <span class="hljs-keyword">EXEC</span>, MULTI, UNWATCH, WATCH, SCRIPT <span class="hljs-keyword">EXISTS</span>, SCRIPT FLUSH, SCRIPT KILL, SCRIPT <span class="hljs-keyword">LOAD</span>, AUTH, ECHO, <span class="hljs-keyword">SELECT</span>, BGREWRITEAOF, BGSAVE, CLIENT KILL, CLIENT LIST, CONFIG <span class="hljs-keyword">GET</span>, CONFIG <span class="hljs-keyword">SET</span>, CONFIG RESETSTAT, DBSIZE, DEBUG OBJECT, DEBUG SEGFAULT, FLUSHALL, FLUSHDB, INFO, LASTSAVE, MONITOR, SAVE, SHUTDOWN, SLAVEOF, SLOWLOG, SYNC, <span class="hljs-keyword">TIME</span></span></code><ul style="display: block;" class="pre-numbering"><li>1</li></ul>
是無法直接遷移到 Codis 上的. 你需要修改你的程式碼, 用其他的方式實現.
