redis7.0基于容器host搭建

Posted on Views:

目标

    1. 使用 host 网络模式；
    1. 增加 Redis 密码认证（requirepass / masterauth）；
    1. 开启 RDB + AOF 双重持久化机制；
    1. 把持久化文件（appendonly.aof, dump.rdb, nodes.conf 等）保存在宿主机挂载目录中，确保数据持久。

1.目录结构

redis-cluster/
├── docker-compose.yml
├── nodes/
│   ├── 7001/redis.conf
│   ├── ...
├── data/
│   ├── 7001/
│   ├── ...

每个 Redis 实例挂载独立的持久化目录到 /data，Redis 会把 AOF、RDB、nodes.conf 等文件放进来。

2.docker-compose.yml

port 7001
bind 0.0.0.0
protected-mode no

# 集群相关
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 127.0.0.1  # 内网IP/公网IP
cluster-announce-port 7001
cluster-announce-bus-port 17001

# 密码认证
requirepass YourStrongPassword
masterauth YourStrongPassword

# 持久化设置：RDB + AOF
appendonly yes
appendfilename "appendonly.aof"
appendfsync everysec

save 900 1
save 300 10
save 60 10000
dbfilename dump.rdb

dir /data

⚠️ 注意：dir /data 这行非常关键，Redis 会在此目录下生成 appendonly.aof、dump.rdb、nodes.conf，确保该目录在 docker-compose 中有挂载。

#!/bin/bash

# 启动容器
docker-compose up -d

echo "等待 Redis 节点启动..."
sleep 5

echo "创建 Redis 集群（带认证）..."
yes yes | docker run -i --rm --net=host redis:7.0.12 \
  redis-cli --cluster create \
  192.168.0.119:7001 \
  192.168.0.119:7002 \
  192.168.0.119:7003 \
  192.168.0.119:7004 \
  192.168.0.119:7005 \
  192.168.0.119:7006 \
  --cluster-replicas 1 \
  -a xxx

5.数据验证

  1. 创建数据：

    1
    redis-cli -a YourStrongPassword -p 7001 set test123 hello

  2. 查看宿主机的持久化文件：

    1
    2
    ls ./data/7001/
    # 应该能看到 appendonly.aof、dump.rdb、nodes.conf
