redis7.4.2单机配置过程实用指南

佚名 2026-10-24 17:40:01

平时做技术实践时，很多问题不是概念不会，而是细节没串起来。拿“redis7.4.2单机配置过程”来说，它看着像小点，放到项目里常会牵出环境、配置、兼容性和维护成本。下面按实际采用顺序，把思路、关键写法和容易踩坑的地方讲清楚，便于大家直接对照操作。

解压源码包

将从官网下载的redis源码压缩包上传到服务器的相关目录下。

[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]# ls
redis-stable.tar.gz

解压并进入解压后的目录中。

[root@hcss-ecs-2851 redis]# tar -zxvf redis-stable.tar.gz
[root@hcss-ecs-2851 redis]# ls
redis-stable  redis-stable.tar.gz
[root@hcss-ecs-2851 redis]# cd redis-stable
[root@hcss-ecs-2851 redis-stable]# ls

安装gcc

[root@hcss-ecs-2851 redis-stable]# yum install -y gcc gcc-c++

安装redis

[root@hcss-ecs-2851 redis-stable]# make
root@hcss-ecs-2851 redis-stable]# make install

轻松测试是否安装成功

[root@hcss-ecs-2851 redis-stable]# cd 
[root@hcss-ecs-2851 ~]# redis-server
9193: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.

自定义设置

自定义目录

[root@hcss-ecs-2851 ~]# cd /opt/soft/redis/
[root@hcss-ecs-2851 redis]# mkdir {etc,lib,log}
[root@hcss-ecs-2851 redis]# ls
etc  lib  log  redis-stable  redis-stable.tar.gz
[root@hcss-ecs-2851 redis]# cp redis-stable/redis.conf etc/
[root@hcss-ecs-2851 redis]# ls etc/
redis.conf

编辑redis.conf

bind 0.0.0.0 # 任意ip均可访问
protected-mode no
port 6379
daemonize yes # 后台运行
pidfile /var/run/redis.pid # 运行时进程id
logfile /opt/soft/redis/log/redis.log #日志文件
dir /opt/soft/redis/lib/
requirepass ********* # 设置密码

新建 systemd 服务文件

[root@hcss-ecs-2851 etc]# cd /etc/systemd/system/
[root@hcss-ecs-2851 system]# vim redis.service
