Redis在ARM架构上的适配主要通过Redis 7.0及以上版本的官方支持实现,编译时使用make MALLOC=libc && make BUILD_TLS=yes,并启用ARM64优化选项如-fmarch=armv8-a+crypto。成功适配的关键步骤:1. 从官网下载源码;2. 配置环境变量export CC=clang CXX=clang++;3. 执行./utils/autogen.sh后make clean && make distclean;4. 最终make install。测试性能显示ARM服务器上Redis单线程QPS可达100万+,与x86相当。高性能内存数据库新发展包括DragonflyDB(Redis兼容,Rust编写,ARM原生支持,吞吐提升3倍)和KeyDB(多线程Redis fork,ARM优化版已发布)。
Redis官方ARM支持
Starting from Redis 7.0, Redis officially supports ARM64 architecture. To build on ARM: git clone https://github.com/redis/redis.git; cd redis; make distclean; make MALLOC=libc. On Apple M1/M2 or AWS Graviton, it runs natively with full performance. Benchmarks show negligible difference vs x86 for most workloads.
ARM服务器部署Redis经验
在阿里云ARM ECS上部署Redis:yum install gcc make tcl -y; wget http://download.redis.io/redis-stable.tar.gz; tar -zxvf redis-stable.tar.gz; cd redis-stable; make && make install. 配置redis.conf bind 0.0.0.0 protected-mode no,启动./src/redis-server redis.conf。高并发测试下,ARM版Redis TPS达80w/s,内存利用率优秀。新发展:ScyllaDB内存版引入ARM加速。
DragonflyDB:Redis新杀手
Dragonfly is a modern in-memory data store, fully compatible with Redis APIs, built from the ground up to achieve multi-core scaling. On ARM64, it delivers 25x higher throughput than Redis on AWS Graviton3. No more single-threaded bottleneck. Ideal for high-performance needs.
KeyDB ARM优化
KeyDB, a high-performance fork of Redis, has native ARM64 builds available via snap install keydb or Docker. Multi-threaded event loop makes it 5x faster on multi-core ARM CPUs like Ampere Altra. Recent updates include active-active replication improvements.
Redis on Raspberry Pi ARM
树莓派4B ARM上安装Redis:sudo apt update; sudo apt install redis-server; redis-cli ping返回PONG即成功。优化:echo 'never' | sudo tee /sys/kernel/mm/transparent_hugepage/enabled; sysctl vm.overcommit_memory=1。适合边缘计算,高性能内存DB趋势向边缘ARM迁移。
高性能内存DB新发展
2023年后,Garnet(Microsoft开源Redis替代,.NET多线程,ARM支持)和LedisDB(Redis兼容,RockDB后端)兴起。Aerospike 7.0 ARM版宣称亚毫秒延迟,云原生内存DB转向ARM以降低成本。新架构如RISC-V也开始兼容Redis forks。
