Redis7.4.2单机环境配置步骤详解

Redis作为高性能键值数据库，其源码编译安装过程需要遵循特定步骤。本文将详细介绍从解压到配置的全流程操作指南。 解压源码包 首先需要将获取的Redis源码压缩包上传至服务器指定位置。通过wget命令可直接下载最新稳定版到本地。 [root@hcss-ecs-2851 ~]# wget https://download.redis.io/redis-stable.tar.gz[root@hcss-ecs-2851 ~]# mv redis-stable.tar.gz /opt/soft/redis/[root@hcss-ecs-2851 ~]# cd /opt/soft/redis/[root@hcss-ecs-2851 redis]# lsredis-stable.tar.gz 执行解压命令后进入生成的目录，可以看到完整的源码文件结构。 [root@hcss-ecs-2851 redis]# tar -zxvf redis-stable.tar.gz[root@hcss-ecs-2851 redis]# lsredis-stable redis-stable.tar.gz[root@hcss-ecs-2851 redis]# cd redis-stable[root@hcss-ecs-2851 redis-stable]# ls00-RELEASENOTES CODE_OF_CONDUCT.md deps LICENSE.txt MANIFESTO redis.conf runtest runtest-moduleapi SECURITY.md src TLS.mdBUGS CONTRIBUTING.md INSTALL Makefile README.md REDISCONTRIBUTIONS.txt runtest-cluster runtest-sentinel sentinel.conf tests utils 安装gcc 编译Redis需要先安装gcc编译器组件，使用yum命令可快速完成环境准备。 [root@hcss-ecs-2851 redis-stable]# yum install -y gcc gcc-c++ 安装redis 通过make命令进行编译安装，完成后系统会将可执行文件部署到默认路径。 [root@hcss-ecs-2851 redis-stable]# makeroot@hcss-ecs-2851 redis-stable]# make install 简单测试是否安装成功 启动redis-server服务，观察控制台输出信息可验证安装结果。 [root@hcss-ecs-2851 redis-stable]# cd [root@hcss-ecs-2851 ~]# redis-server9193:C 24 Mar 2025 12:03:19.847 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.9193:C 24 Mar 2025 12:03:19.847 * oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo9193:C 24 Mar 2025 12:03:19.847 * Redis version=7.4.2, bits=64, commit=00000000, modified=0, pid=9193, just started9193:C 24 Mar 2025 12:03:19.847 # Warning: no config file specified, using the default config.
