1. 先确认 CentOS 系统版本cat /etc/redhat-release会出现类似下面的结果CentOS Linux release 7.x.x→ 是 CentOS 7CentOS Stream release 8→ 是 CentOS 8CentOS Stream release 9→ 是 CentOS 92. 根据系统版本安装 Redis① 如果是 CentOS 7运行yum install -y https://rpms.remirepo.net/enterprise/remi-release-7.rpm yum install -y redis --enablereporemi② 如果是 CentOS 8 / Stream 8运行yum install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm yum install -y redis --enablereporemi③ 如果是 CentOS 9 / Stream 9yum install -y https://rpms.remirepo.net/enterprise/remi-release-9.rpm yum install -y redis --enablereporemi3. 启动并设置开机自启systemctl start redis systemctl enable redis4. 确认 Redis 安装成功systemctl status redis看到active (running)就成功了5、常用配置bind 0.0.0.0 # 允许所有IP访问 protected-mode no # 关闭保护模式 requirepass 你的密码 # 设置密码强烈建议6、Redis 常用命令# 启动 systemctl start redis # 停止 systemctl stop redis # 重启 systemctl restart redis # 查看状态 systemctl status redis # 连接客户端 redis-cli # 带密码连接 redis-cli -a 你的密码
