部署环境

CPU 架构: loongarch64
系统版本: Kylin Linux Advanced Server V10 (Tercel)
Nacos 版本: 5.0.7

注意: 由于 redis 5.0.7 版本自带的 jemalloc 版本为 5.1.0，该版本不兼容 loongarch64 平台，所以编译 redis 之前需要填更新 redis 源码中自带的 jemalloc 版本

源码编译 redis

从 releases page 下载指定版本的 redis 源码

1	wget https://download.redis.io/releases/redis-5.0.7.tar.gz

解压源码

1	tar xf redis-5.0.7.tar.gz -C /usr/local

升级 jemalloc，因为原生自带的 jemalloc 不支持 loongarch64 架构，从 jemalloc 5.3.0 开始支持 loongarch。

cd /usr/local/redis-5.0.7/deps

# 删除旧版本的 jemalloc
rm -rf jemalloc

# 下载新版本的 jemalloc
wget https://github.com/jemalloc/jemalloc/releases/download/5.3.0/jemalloc-5.3.0.tar.bz2

# 解压新版本的 jemalloc
tar xvjf jemalloc-5.3.0.tar.bz2 && mv jemalloc-5.3.0 jemalloc

修改 deps/Makefile 文件的 jemalloc 选项，修改 --with-version 的值，修改后内容如下：

jemalloc: .make-prerequisites
        @printf '%b %b\n' $(MAKECOLOR)MAKE$(ENDCOLOR) $(BINCOLOR)$@$(ENDCOLOR)
        cd jemalloc && ./configure --with-version=5.3.0-0-g0 --with-lg-quantum=3 --with-jemalloc-prefix=je_ --enable-cc-silence CFLAGS="$(JEMALLOC_CFLAGS)" LDFLAGS="$(JEMALLOC_LDFLAGS)"
        cd jemalloc && $(MAKE) CFLAGS="$(JEMALLOC_CFLAGS)" LDFLAGS="$(JEMALLOC_LDFLAGS)" lib/libjemalloc.a

.PHONY: jemalloc

将 –with-version=5.1.0-0-g0 改成 –with-version=5.3.0-0-g0

编译 Redis

# 回到 redis 源码根目录
cd /usr/local/redis-5.0.7

# 执行 make
make

# 执行安装 make install
make install
