1.準備
1.1.在/usr/local目錄下新建redis目錄，並且進入，下載
wget http://download.redis.io/releases/redis-2.8.6.tar.gz
1.2.解壓
tar xzf redis-2.8.6.tar.gz
1.3.安裝gcc環境等基本組件
yum -y install gcc automake autoconf libtool make
2.安裝
2.1進入根目錄
cd redis-2.8.6/
2.2編譯安裝
make
3.部署
3.1運行腳本，在redis目錄下生成bin
make install PREFIX=/usr/local/redis
3.2在/usr/local/redis目錄下新建/etc目錄
mkdir etc
3.3將redis-2.8.6目錄下的配置文件redis.conf移動到/etc目錄下
4.在目錄（/usr/local/redis）下運行
./bin/redis-server ./etc/redis.conf
5.停止運行
bin/redis-cli shutdown
6.查看redis節點狀態
運行 bin/redis-cli
輸入命令 info

redis主從
1.按照上述配置在主從服務器上安裝完redis
2.主從服務器修改hosts
172.16.0.6 redis.master.idc.baiduyun.com
172.16.0.4 redis.slave1.idc.baiduyun.com
3.在從服務器上修改redis配置文件
slaveof redis.master.idc.baiduyun.com 6379
4.主從服務器啓動redis,驗證
主服務器上運行./bin/redis-cli客戶端腳本，輸入：
set key1 val1
從服務器上運行./bin/redis-cli客戶端腳本，輸入：
get key1

redis sentinel集羣搭建（3臺雲服務器，redis集羣和sentinel集羣生成環境中在不同的服務器上，這裏因爲只有3臺雲服務器，所以複用）
1.在每臺服務器上安裝redis（可以參考上面安裝）
2.在/usr/local/redis/etc目錄下新建配置文件sentinel.conf，文件內容如下：
port 26379
logfile "sentinel.log"
dir /home/local/redis-sentinel/log/
sentinel monitor mymaster redis.master.idc.baiduyun.com 6379 2
sentinel down-after-milliseconds mymaster 30000
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 180000
3.在每臺服務器的/usr/local/redis/目錄下運行：
./redis-2.8.6/src/redis-sentinel /usr/local/redis/etc/sentinel.conf > /home/local/redis-sentinel/tmp/tmp.log &
4.查看sentinel狀態
連接sentinel
bin/redis-cli -p 26379
查看狀態
info
5. 測試
將redis主節點停用，1分鐘後（在配置文件中有機器檢測時間的限制，所以redis節點掛掉後不會立刻被sentinel發現）查看每個redis節點的狀態，會發現主節點隨機轉移到某個從節點
ps:sentinel節點之間通過向redis主節點發布訂閱消息來發現其他sentinel節點
