golang-mod开启

go env -w  GO111MODULE=on

go env -w GOPROXY=https://goproxy.cn,direct

go mod init xxx/abcxx
go mod init github.com/gomodule/redigo/redis

go mod edit -replace=aaaaversion=bbbbversion

go build -o server main.go server.go

windows下修成go build -o server.exe main.go server.go

go build  go-main\chapter06\fundemo01\main

//如果没有设置密码在linux下面进行如下配置，打开redis-cli执行如下命令`CONFIG SET protected-mode no`
