1. 部署劃分
| IP | 角色 |
| 192.168.92.100 | Master |
| 192.168.92.101 | Slave |
| 192.168.92.102 | Slave |
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
聲明:下面流程3個節點依次操作
- 建立配置目錄
mkdir /usr/local/redis/conf -p - 建立資料目錄
mkdir /usr/local/redis/data -p - 建立日志目錄
mkdir /usr/local/redis/log -p 4. 修改配置檔案
3個節點依次建立一個redis.conf配置檔案在conf目錄下面
vi /usr/local/redis/conf/redis.conf 主節點配置
# 放行通路IP的限制 多個用空格隔開
# 0.0.0.0 代表無限制
bind 0.0.0.0
# 背景啟動開啟
daemonize yes
# 日志存儲目錄以及日志檔案名
logfile "/usr/local/redis/log/redis.log"
# rdb資料檔案名
dbfilename dump.rdb
# aof模式開啟
appendonly no
# aof資料檔案名
appendfilename "appendonly.aof"
#rdb資料檔案和aof資料檔案存儲目錄
dir /usr/local/redis/data
# 設定密碼
requirepass 123456
# 從節點通路主節點的密碼(必須和requirepass 一緻)
masterauth 123456
#從節點隻讀模式
replica-read-only yes 2個Slave節點配置
vi /usr/local/redis/conf/redis.conf 主節點配置
# 放行通路IP的限制 多個用空格隔開
# 0.0.0.0 代表無限制
bind 0.0.0.0
# 背景啟動開啟
daemonize yes
# 日志存儲目錄以及日志檔案名
logfile "/usr/local/redis/log/redis.log"
# rdb資料檔案名
dbfilename dump.rdb
# aof模式開啟
appendonly no
# aof資料檔案名
appendfilename "appendonly.aof"
#rdb資料檔案和aof資料檔案存儲目錄
dir /usr/local/redis/data
# 設定密碼
requirepass 123456
# 從節點通路主節點的密碼(必須和requirepass 一緻)
masterauth 123456
#從節點隻讀模式
replica-read-only yes
# 從節點從屬于那個主節點
