使用docker 部署redis 单机 Cluster模式 集群3主3从 可视化web页面

1 使用docker部署单机的redis

1.拉取Redis镜像

# 拉取最新版本
docker pull redis:latest

# 或指定版本
docker pull redis:7.2

2. 创建Redis配置文件

# 创建配置文件目录
mkdir -p /docker/redis/conf
mkdir -p /docker/redis/data

# 创建Redis配置文件
nano /docker/redis/conf/redis.conf

配置文件内容如下：

# 基础配置
port 6379
bind 0.0.0.0
protected-mode no
daemonize no

# 持久化配置
appendonly yes
appendfilename "appendonly.aof"
appendfsync everysec

# 内存配置
maxmemory 1gb
maxmemory-policy allkeys-lru

# 日志配置
loglevel notice
logfile "/data/redis.log"

# 密码配置（可选）
requirepass your_password

3.启动Redis容器

docker run -d \
  --name redis \
  --restart always \
  -p 6379:6379 \
  -v /docker/redis/conf/redis.conf:/etc/redis/redis.conf \
  -v /docker/redis/data:/data \
  redis:latest \
  redis-server /etc/redis/redis.conf

4 测试连接

# 进入容器
docker exec -it redis redis-cli

# 如果设置了密码，需要认证
AUTH your_password

# 测试
SET test "Hello Redis"
GET test

2 Redis集群安装

1 创建Docker网络

docker network create redis-net

2 创建集群配置文件
为每个节点创建配置文件：

# 创建目录结构
mkdir -p /docker/redis-cluster/7001/conf   
mkdir -p /docker/redis-cluster/7001/data
mkdir -p /docker/redis-cluster/7002/conf   
mkdir -p /docker/redis-cluster/7002/data
mkdir -p /docker/redis-cluster/7003/conf   
mkdir -p /docker/redis-cluster/7003/data
mkdir -p /docker/redis-cluster/7004/conf   
mkdir -p /docker/redis-cluster/7004/data
mkdir -p /docker/redis-cluster/7005/conf   
mkdir -p /docker/redis-cluster/7005/data
mkdir -p /docker/redis-cluster/7006/conf   
mkdir -p /docker/redis-cluster/7006/data

3.创建配置文件

nano /docker/redis-cluster/7001/conf/redis.conf
nano /docker/redis-cluster/7002/conf/redis.conf
nano /docker/redis-cluster/7003/conf/redis.conf
nano /docker/redis-cluster/7004/conf/redis.conf
nano /docker/redis-cluster/7005/conf/redis.conf
nano /docker/redis-cluster/7006/conf/redis.conf

配置内容：

port 7001
bind 0.0.0.0
protected-mode no
daemonize no
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000

port 7004
bind 0.0.0.0
protected-mode no
daemonize no
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 172.20.0.14
cluster-announce-port 7004
cluster-announce-bus-port 17004

port 7005
bind 0.0.0.0
protected-mode no
daemonize no
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 172.20.0.15
cluster-announce-port 7005
cluster-announce-bus-port 17005

port 7006
bind 0.0.0.0
protected-mode no

cluster-node-timeout 5000
cluster-announce-ip 172.20.0.16
cluster-announce-port 7006
cluster-announce-bus-port 17006

3.创建docker-compose.yml

nano /docker/redis-cluster/docker-compose.yml

内容如下

version: 'docker-compose 版本号'
services:
  redis1:
    image: redis:latest
    container_name: redis1
    networks:
      redis-net:
        ipv4_address: 172.20.0.11
    volumes:
      - ./7001/conf/redis.conf:/etc/redis/redis.conf
      - ./7001/data:/data
    command: redis-server /etc/redis/redis.conf
    ports:
      - "7001:7001"
      - "17001:17001"

  redis2:
    image: redis:latest
    container_name: redis2
    networks:
      redis-net:
        ipv4_address: 172.20.0.12
    volumes:
      - ./7002/conf/redis.conf:/etc/redis/redis.conf
      - ./7002/data:/data
    command: redis-server /etc/redis/redis.conf
    ports:
      - "7002:7002"
      - "17002:17002"

  # 重复类似配置直到redis6
  # ...

networks:
  redis-net:
    driver: bridge
    ipam:
      config:
        - subnet: 172.20.0.0/16

4.启动集群

# 启动所有容器
cd /docker/redis-cluster
docker-compose up -d

# 进入redis1 创建集群
docker exec -it redis1 redis-cli --cluster create \
  172.20.0.11:7001 \
  172.20.0.12:7002 \
  172.20.0.13:7003 \
  172.20.0.14:7004 \
  172.20.0.15:7005 \
  172.20.0.16:7006 \
  --cluster-replicas 1

3 监控和管理

1 安装Redis Commander（Web管理界面）

docker run -d \
  --name redis-commander \
  --restart always \
  -p 8081:8081 \
  -e REDIS_HOSTS=local:redis:6379 \
  rediscommander/redis-commander:latest

2.常用管理命令

# 查看容器状态
docker ps | grep redis

# 查看容器日志
docker logs redis

# 查看集群信息
docker exec -it redis1 redis-cli cluster info

# 查看节点信息
docker exec -it redis1 redis-cli cluster nodes

4 备份和恢复

1 创建备份脚本

#!/bin/bash
BACKUP_DIR="/docker/redis/backups"
DATE=$(date +%Y%m%d_%H%M%S)
mkdir -p $BACKUP_DIR

# 创建备份
docker exec redis redis-cli SAVE
docker cp redis:/data/dump.rdb $BACKUP_DIR/dump_$DATE.rdb

2 设置定时备份

# 编辑crontab
crontab -e

# 添加定时任务（每天凌晨2点备份）
0 2 * * * /docker/redis/backup.sh

5.性能优化建议

# redis.conf 性能优化配置

# 内存优化
maxmemory-samples 10
activedefrag yes
active-defrag-ignore-bytes 100mb
active-defrag-threshold-lower 10
active-defrag-threshold-upper 30

# 持久化优化
save 900 1
save 300 10
save 60 10000

# 网络优化
tcp-keepalive 300
timeout 0
tcp-backlog 511

6 安全配置

# redis.conf 安全配置

# 设置访问密码
requirepass your_strong_password

# 禁用危险命令
rename-command FLUSHDB ""
rename-command FLUSHALL ""
rename-command CONFIG ""
rename-command KEYS ""

# 设置最大连接数
maxclients 10000
