1、主從方案
單主、多從或單主階梯從
啓動
# ./src/redis-server redis.conf
注意註釋掉這一行，否則主從不能正常連接
#bind 127.0.0.1
本例以1主1從爲例進行說明
step1：修改redis.conf
註釋掉bind 127.0.0.1這些一行
step2:準備從機器配置文件redis-6380.conf
在redis根目錄新建一個conf、data目錄
將redis.conf拷貝到conf目錄下，重命名爲redis-6380.conf，文件內容如下所示
step3:啓動主、從redis

step4:檢查主從是否啓動成功（主、從機器都可以查看）
---這是在主機上的查看情況

2、哨兵方案
哨兵方案搭建成功後，集羣會主動將集羣配置信息寫到你的配置文件中
哨兵啓動
# ./src/redis-sentinel sentinel.conf
