Redis集群方案，Codis安装测试
Redis集群方案，Codis安裝測試
?
1，關于豌豆莢開源的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分布式集群解決方案,且完全兼容Twemproxy。Twemproxy對于上一層的應用來說,?連接Codis Proxy（Redis代理服務）和連接原生的Redis服務器沒有明顯的區別,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、不停機的數據遷移等工作,?所有底層的一切處理,?對于客戶端來說是透明的。總之，可以簡單的認為后臺連接的是一個內存無限大的Redis服務。Codis遵循MIT開源協議發布，更多關于Codis的信息請登錄其在GitHub的主頁查看。
Codis?是一個分布式?Redis?解決方案,?對于上層的應用來說,?連接到?Codis Proxy?和連接原生的?Redis Server?沒有明顯的區別?(不支持的命令列表),?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,?不停機的數據遷移等工作,?所有后邊的一切事情,?對于前面的客戶端來說是透明的,?可以簡單的認為后邊連接的是一個內存無限大的?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
參考文檔：
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。
如果被墻使用golang中國下載http://golangtc.com/download。
cd /usr/loca/
wget https://storage.googleapis.com/golang/go1.4.2.linux-amd64.tar.gz
tar -zxvf go1.4.2.linux-amd64.tar.gz

設置環境變量，vi /etc/profile
#set go & codis environment
Export GOROOT=/usr/local/go
Export PATH=$PATH:$GOROOT/bin
Export GOPATH=/usr/local/codis
1
2
下載codis
cd /usr/local
git clone https://github.com/wandoulabs/codis.git
#將codis的pkg包拷貝到$GOPATH目錄。
mkdir -p /usr/local/codis/src/github.com/wandoulabs/codis
cp /usr/local/codis/pkg/ /usr/local/codis/cmd/ /usr/local/codis/src/github.com/wandoulabs/codis -R
安裝codis，需要下載依賴包。比較慢，依賴
#安裝編譯工具
yum groupinstall "Development Tools"
#執行編譯測試腳本，編譯go和reids。
sh /usr/local/codis/bootstrap.sh

安裝測試成功，就可以配置了。
編譯后的二進制文件在/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
mkdir /usr/local/zookeeper/logs

vi /usr/local/zookeeper/conf/zoo.cfg配置文件
tickTime=2000
clientPort=2181
dataDir=/usr/local/zookeeper/data

啟動zookeeper
sh /usr/local/zookeeper/bin/zkServer.sh start

啟動Codis服務，之前必須啟動zookeeper，sample目錄有簡單的集群配置。
startall.sh腳本會同時將redis啟動。
# sh /usr/local/codis/sample/startall.sh

啟動之后就可以看到zookeeper里面的數據了。
[zk: localhost:2181(CONNECTED) 8] ls /zk/codis/db_test
[migrate_manager, fence, migrate_tasks, LOCK, slots, actions, servers, proxy]

3，管理界面顯示
啟動之后就可以訪問admin頁面了。
數據遷移界面
整個桶結構
4，總結
Codis可以完美的解決Redis集群問題，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。支持數據擴展。
但是并不是所有的redis命令都支持。
如果你使用以下命令:
KEYS, MOVE, OBJECT, RENAME, RENAMENX, SORT, SCAN, BITOP,MSETNX, BLPOP, BRPOP, BRPOPLPUSH, PSUBSCRIBE，PUBLISH, PUNSUBSCRIBE, SUBSCRIBE, UNSUBSCRIBE, DISCARD, EXEC, MULTI, UNWATCH, WATCH, SCRIPT EXISTS, SCRIPT FLUSH, SCRIPT KILL, SCRIPT LOAD, AUTH, ECHO, SELECT, BGREWRITEAOF, BGSAVE, CLIENT KILL, CLIENT LIST, CONFIG GET, CONFIG SET, CONFIG RESETSTAT, DBSIZE, DEBUG OBJECT, DEBUG SEGFAULT, FLUSHALL, FLUSHDB, INFO, LASTSAVE, MONITOR, SAVE, SHUTDOWN, SLAVEOF, SLOWLOG, SYNC, TIME
是無法直接遷移到?Codis?上的.?你需要修改你的代碼,?用其他的方式實現.
