使用 Docker Compose 安装 Redis 7.2.4

前面是指南，后面是主要步骤实际执行日志

使用 Docker Compose 安装 Redis 7.2.4

以下是使用 Docker Compose 安装 Redis 7.2.4 的完整指南：

1. 创建项目目录和文件

bash

复制

下载

# 创建项目目录
mkdir redis-docker && cd redis-docker# 创建必要目录
mkdir -p data conf

2. 创建 docker-compose.yml 文件

yaml

复制

下载

# docker-compose.yml
version: '3.8'services:redis:image: redis:7.2.4container_name: redis-serverrestart: unless-stoppedports:- "6379:6379"volumes:- ./data:/data- ./conf/redis.conf:/usr/local/etc/redis/redis.confcommand: redis-server /usr/local/etc/redis/redis.confenvironment:- TZ=Asia/Shanghainetworks:- redis-netnetworks:redis-net:driver: bridge

3. 创建 Redis 配置文件

bash

复制

下载

# 创建配置文件
cat <<EOF > conf/redis.conf
# Redis 7.2.4 基础配置bind 0.0.0.0
port 6379
protected-mode yes
daemonize no
supervised no
pidfile /var/run/redis_6379.pid

EOF

4. 启动 Redis 服务

bash

复制

下载

# 启动服务
docker-compose up -d# 查看服务状态
docker-compose ps# 预期输出：
#     Name                   Command               State           Ports
# ----------------------------------------------------------------------------
# redis-server   docker-entrypoint.sh redis ...   Up      0.0.0.0:6379->6379/tcp

5. 验证安装

bash

复制

下载

# 测试 Redis 连接
docker-compose exec redis redis-cli ping
# 应返回: PONG# 查看 Redis 信息
docker-compose exec redis redis-cli info server# 检查持久化
docker-compose exec redis redis-cli save
ls -lh data/

6. 基本操作和管理

进入 Redis CLI

bash

复制

下载

docker-compose exec redis redis-cli

常用命令

bash

复制

下载

# 设置键值
SET mykey "Hello Redis"# 获取键值
GET mykey# 查看所有键
KEYS *# 查看内存使用
INFO memory# 查看客户端连接
CLIENT LIST

管理服务

bash

复制

下载

# 停止服务
docker-compose down# 启动服务
docker-compose up -d# 重启服务
docker-compose restart# 查看日志
docker-compose logs -f

7. 自定义配置

要修改 Redis 配置：

1. 编辑 conf/redis.conf 文件

2. 重启服务：docker-compose restart

常用配置选项：

• 设置密码：取消注释并修改 requirepass yourstrongpassword

• 调整内存限制：修改 maxmemory 值

• 更改持久化策略：设置 appendonly no 禁用 AOF

• 启用集群模式：取消注释集群相关配置

8. 数据持久化说明

• 数据保存在 ./data 目录中：

  • dump.rdb：RDB 快照文件

  • appendonly.aof：AOF 日志文件

• 即使容器重启或删除，数据也会保留

• 定期备份 data 目录以确保数据安全

9. 升级 Redis 版本

要升级 Redis 版本：

1. 修改 docker-compose.yml 中的镜像标签：

   yaml

   复制

   下载

   image: redis:7.2.5  # 新版本

2. 执行升级：

   bash

   复制

   下载

   docker-compose down
   docker-compose pull
   docker-compose up -d

10. 安全建议

1. 设置强密码：

   • 在 redis.conf 中设置 requirepass

   • 连接时使用：redis-cli -a yourpassword

2. 限制访问：

   bash

   复制

   下载

   # 在服务器防火墙限制访问
   sudo ufw allow from 192.168.1.0/24 to any port 6379

3. 启用 TLS（高级）：

   conf

   复制

   下载

   # 在 redis.conf 中添加
   tls-port 6379
   tls-cert-file /path/to/redis.crt
   tls-key-file /path/to/redis.key

这个安装方案提供了 Redis 7.2.4 的稳定运行环境，包含了合理的默认配置和持久化设置，适合生产环境使用。
