1. 代码

https://github.com/KDr2/redis-leveldb

git clone git://github.com/KDr2/redis-leveldb.git
cd redis-leveldb
git submodule init
git submodule update

2. 在 centos9 中编译

注意⚠️：src/rl.h 中定义了一次性读取 socket 内容的 READ_BUFFER 是 81920，所以如果客户端传输的内容有可能大于这个值，那么需要手动修改一下。

2.1 安装依赖

I. 安装源 epel-release

wget https://dl.fedoraproject.org/pub/epel/9/Everything/aarch64/Packages/e/epel-release-9-7.el9.noarch.rpm
rpm -Uvh epel-release*rpm

或者

yum install -i epel-release

II. 安装 libev-devel 和 gmp-devel

来源：https://rhel.pkgs.org/9/epel-aarch64/libev-devel-4.33-5.el9.aarch64.rpm.html

dnf install -y libev-devel gmp-devel snappy

III.安装 snappy-devel

来源：https://centos.pkgs.org/9-stream/centos-crb-x86_64/snappy-devel-1.1.8-8.el9.x86_64.rpm.html

dnf --enablerepo=crb install -y snappy-devel

2.2 编译 redis-leveldb

make

也可以增加编译选项

[LIBEV=LIBEV_PREFIX GMP=GMP_PREFIX DEBUG=1] make

• DEBUG=1 为调试模式，每次接收到请求后都会打印所以的信息。

3. 启动服务

./redis-leveldb -h

参数 - -d: run redis-level as a daemon process - -H : host addr to listen on(eg: 127.0.0.1) - -P : port to listen on(default 8323) - -D : leveldb data dir(default “redis.db” under your work directory) - -M : run in multi-db mode and set its db count to , each db in the server is a separatly leveldb database and its data directory is a directory named db- under the directory you specified with the option -D; you can use command select to switch db on the client side while redis-leveldb is running in this mode.
