Redis概述** Redis(Remote Dictionary Server)是一个开源的、内存中的、键值对数据库。它以其高性能、低延迟和丰富的功能而闻名,广泛应用于缓存、消息队列和数据库等场景。 Redis采用单线程架构,通过非阻塞IO和内存操作来实现高吞吐量和低延迟。它支持多种数据结构,包括字符串、哈希、列表、集合和有序集合,可以满足不同场景的存储需求。 # 2. Redis安装 ### 2.1 安装准备 **2.1.1 系统环境检查** 安装Redis之前,需要检查系统环境是否满足要求: - 操作系统:Linux、macOS、Windows - CPU:64位处理器 - 内存:至少1GB - 硬盘空间:根据数据量而定 **2.1.2 依赖包安装** Redis需要依赖以下包: - glibc 2.14或更高版本 - zlib 1.2.8或更高版本 - jemalloc 3.6或更高版本 在Ubuntu系统中,可以使用以下命令安装依赖包: ```bash sudo apt-get install build-essential tcl ``` ### 2.2 下载安装包 **2.2.1 官方网站下载** 从Redis官方网站(https://redis.io/download)下载最新版本的Redis安装包。 **2.2.2 第三方仓库下载** 也可以从第三方仓库下载Redis安装包,例如: - Ubuntu:`sudo apt-get install redis-server` - CentOS:`sudo yum install redis` ### 2.3 解压安装 **2.3.1 解压安装包** 将下载的Redis安装包解压到指定目录,例如: ```bash tar -xzvf redis-7.0.5.tar.gz ``` **2.3.2 创建Redis用户和组** 创建Redis用户和组,并赋予Redis用户对Redis安装目录的读写权限: ```bash sudo useradd -r redis sudo groupadd redis sudo chown -R redis:redis /path/to/redis-7.0.5 ``` # 3. Redis配置 ### 3.1 配置文件解析 Redis配置文件通常位于`/etc/redis/redis.conf`,它包含了Redis服务器的各种配置选项。 #### 3.1.1 常用配置项说明 | 配置项 | 说明 | 默认值 | |---|---|---| | `port` | Redis服务器监听的端口号 | 6379 | | `bind` | Redis服务器监听的IP地址 | 127.0.0.1 | | `daemonize` | 是否以守护进程模式运行 | yes | | `pidfile` | 守护进程PID文件路径 | /var/run/redis.pid | | `loglevel` | 日志级别 | notice | | `logfile` | 日志文件路径 | /var/log/redis/redis.log | | `maxmemory` | Redis服务器的最大内存限制 | 0 (无限制) | | `maxmemory-policy` | 当内存达到`maxmemory`限制时的淘汰策略 | volatile-lru | | `save` | RDB快照保存策略 | 900 1 300 10 60 10000 | | `stop-writes-on-bgsave-error` | 当RDB快照保存失败时是否停止写入 | yes | | `rdbcompression` | 是否对RDB快照进行压缩 | yes | | `rdbchecksum` | 是否对RDB快照进行校验 | yes | | `aof-rewrite-percentage` | AOF重写触发百分比 | 100 | | `aof-rewrite-min-size` | AOF重写触发最小文件大小 | 64MB | #### 3.1.2 配置文件修改 修改配置文件时,需要根据具体需求调整相关配置项的值。例如,如果需要更改Redis服务器监听的端口号,
