Redix

可能是我毕业设计的一小部分，一个精简版 Redis，它只是个“小玩具”

支持的命令：

• SET
• SETNX
• GET
• INCR
• INCRBY
• DECR
• DECRBY
• KEYS
• TTL
• EXPIRE
• DEL
• FLUSHALL
• FLUSHDB: 没有区分 db，所以直接调用的 FLUSHALL
• AUTH
• PING
• QUIT
• SHUTDOWN

安装

二进制

releases

Go Install

$ go install go.chensl.me/redix/cmd/redix-server@latest
go: downloading go.chensl.me/redix v0.1.0
$ redix-server # 数据默认存放在当前目录的 data 文件夹下

使用 redis-cli 或 iredis 连接：

$ redis-cli -p 6380

Docker

$ mkdir data
$ docker run -d -p 6380:6380 \
    --name redix \
    -v $PWD/data:/data \
    -e REDIX_DATA_DIR=/data \
    -e REDIX_PASSWORD=123456 \
    maolonglong/redix:latest

配置

可通过配置文件或环境变量进行配置（环境变量优先级更高），配置文件示例：config.yml

配置文件可放置在（按顺序查找）：

• 当前目录 config.yml
• 用户目录 .redix.yml
• /etc/redix/config.yml

可用配置和默认值：

• REDIX_HOST: 0.0.0.0
• REDIX_PORT: 6380
• REDIX_PASSWORD: ""
• REDIX_DATA_DIR: ./data
