1. 部署劃分
| IP | 角色 | 端口 |
| 192.168.45.80 | Master | 6380 |
| 192.168.45.80 | Slave | 6381 |
| 192.168.45.80 | Slave | 6382 |
2. 單機安裝Redis
首先在在3台伺服器上分别安裝Redis單機環境
Linux環境 安裝 Redis-6.2.6 配置運作_01
3. 建立配置/資料/日志目錄
- 建立配置目錄+資料目錄+日志目錄
mkdir /usr/local/redis/conf/redis01 -p
mkdir /usr/local/redis/conf/redis02 -p
mkdir /usr/local/redis/conf/redis03 -p
mkdir /usr/local/redis/data/redis01 -p
mkdir /usr/local/redis/data/redis02 -p
mkdir /usr/local/redis/data/redis03 -p
mkdir /usr/local/redis/log/redis01 -p
mkdir /usr/local/redis/log/redis02 -p
mkdir /usr/local/redis/log/redis03 -p 4. 修改配置檔案

firewall-cmd --zone=public --add-port=6381/tcp --permanent
firewall-cmd --zone=public --add-port=6382/tcp --permanent

/app/redis-6.2.6/src/redis-server /usr/local/redis/conf/redis03/redis-6382.conf 7. 檢視redis狀态
