redigo's Introduction

RediGO

RediGO是用Go语言实现的Redis服务器。目前实现了Redis的主要数据结构、网络协议、expire、Multi、发布订阅等功能。

关键功能：

支持的命令

数据结构	已实现
string	GET, SET, SETNX, INCR, DECR, INCRYBY, DECRBY, APPEND, STRLEN, SETBIT, GETBIT
list	LPUSH, LPOP, RPUSH, RPOP, LRANGE, LINDEX, LLEN, LPUSHRPOP
hash	HGET, HSET, HDEL, HEXISTS, HGETALL, HKEYS, HLEN, HMGET, HSETNX, HINCRBY, HSTRLEN, HVALS
set	SADD, SMEMBERS ,SISMEMBER, SRANDMEMBER, SREM, SPOP, SDIFF, SINTER, SCARD, SDIFFSTORE, SINTERSTORE, SUNION
zset	ZADD, ZSCORE, ZREM, ZRANK, ZPOPMIN, ZPOPMAX, ZCARD, ZRANGE, ZRANGEBYSCORE
key	TTL, PTTL, EXPIRE, PERSIST, DEL, EXISTS, TYPE, KEYS, RENAME, RENAMENX, MOVE, RANDOMKEY
Geo	GEOADD, GEOPOS, GEODIST, GEOHASH, GEORADIUS, GEORADIUSBYMEMBER
事务	MULTI, EXEC, DISCARD, WATCH, UNWATCH
发布订阅	SUBSCRIBE, PUBLISH, PSUBSCRIBE
服务器	PING
数据库	SELECT, FLUSHDB, DBSIZE, BGREWRITEAOF, SAVE, BGSAVE

运行RediGO

1. 配置文件

# 端口号
port: 6381
# 数据库数量
databases: 16
# 是否开启 AOF
appendOnly: false
# AOF文件
aofFileName: appendonly-1.log
# RDB持久化文件
dbFileName: dump.rdb
# 本机的集群地址
self: 127.0.0.1:16381
# 对客户端开放的地址
address: 127.0.0.1:6381
# 开启集群模式
enableClusterMode: true
# 集群中的其他节点
peers:
  - 127.0.0.1:16382
  - 127.0.0.1:16383

2. linux

编译源文件

# Makefile编译
make build ARCH="..." OS="..."

运行target目录下的可执行文件

# 运行可执行文件
./target/redigo --config="配置文件"
# 或编译 + 运行
make run CONFIG_FILE="配置文件" ARCH="..." OS="..."

3. Windows

Windows版本使用Go推荐的goroutine+channel机制实现服务器，持久化使用goroutine+锁实现，与linux版的epoll和fork实现有区别。推荐使用Linux版本。

运行编译脚本

# Windows系统
./build-windos.bat

运行可执行文件，并指定配置文件位置（可选）

./redigo.exe --config redigo.yaml

4. 使用Docker运行

从Docker仓库拉取镜像

docker pull xxjay/redigo:latest

创建容器并运行，注意端口的映射

docker run -d --name redigo -p 6381:6381 xxjay/redigo:latest

性能测试

详细结果见 /docs/benchmark.md
