Docker 部署 Redis

快速启动​

# 基本运行
docker run -d --name redis -p 6379:6379 redis:7-alpine

# 带数据持久化
docker run -d \
  --name redis \
  -p 6379:6379 \
  -v redis_data:/data \
  redis:7-alpine redis-server --appendonly yes

Docker Compose 部署​

version: '3.8'

services:
  redis:
    image: redis:7-alpine
    container_name: redis
    restart: always
    ports:
      - "6379:6379"
    volumes:
      - redis_data:/data
    command: redis-server --appendonly yes

volumes:
  redis_data:

自定义配置​

redis.conf​

# 网络配置
bind 0.0.0.0
protected-mode yes
port 6379
tcp-backlog 511

# 内存配置
maxmemory 2gb
maxmemory-policy allkeys-lru

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

save 900 1
save 300 10
save 60 10000

# 慢查询日志
slowlog-log-slower-than 10000
slowlog-max-len 128

# 密码
requirepass your_password

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

常用命令​

# 连接 Redis
docker exec -it redis redis-cli
docker exec -it redis redis-cli -a your_password

# 查看信息
docker exec redis redis-cli INFO
docker exec redis redis-cli INFO stats

# 查看键
docker exec redis redis-cli KEYS "*"
docker exec redis redis-cli DBSIZE

# 监控命令
docker exec redis redis-cli MONITOR

# 备份
docker exec redis redis-cli SAVE
docker exec redis redis-cli BGSAVE

    ports:
      - "7001:6379"
    volumes:
      - redis_1:/data

    volumes:
      - redis_2:/data

  redis-3:
    image: redis:7-alpine
    command: redis-server --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000 --appendonly yes
    ports:

最佳实践​

最佳实践
  • ✅ 使用密码保护 Redis
  • ✅ 限制最大内存使用
  • ✅ 启用持久化（AOF + RDB）
  • ✅ 禁用危险命令
  • ✅ 监控内存使用率
  • ✅ 使用连接池
  • ✅ 设置合理的超时时间
