Master安裝Redis
- 從Redis官方網站下載下傳Redis的安裝檔案
- CentOSMini安裝GCC環境
yum install -y gcc-g++
- 編譯
5.0版本的Redis安裝需要加上參數
make MALLOC=libc
- 安裝
make install PROFIX=/usr/local/redis
拷貝配置檔案
将Redis的配置檔案拷貝到Redis的安裝目錄(/usr/local/redis/bin)

其他配置都和master一樣,注釋内容是需要修改的.
replicaof master 6379
為什麼不是slaveof呢?
詳情請參考:<太無奈！Redis 作者被迫修改 master-slave 架構的描述>
開啟master和slave
兩台機器都在redis目錄下執行
./redis-server ./redis.conf
其中master啟動之後由log記錄可以發現.
測試主從同步是否成功
我這裡的環境是一台Master兩台slave,master set一個key之後slave自動同步.
預設情況下slave隻能對master提供一個讀操作,不提供寫操作.
