## 安装go环境 ##

wget wget https://golang.google.cn/dl/go1.21.5.linux-amd64.tar.gz
    
     tar -zxvf go1.21.5.linux-amd64.tar.gz -C /usr/local/lib/
    
     ln -s /usr/local/lib/go/bin/* /usr/bin/
    
    # 可选配置
    go env -w GO111MODULE=on
    go env -w GOPROXY=https://goproxy.cn,direct
    
    go version

## 安装dlv ##

go install github.com/go-delve/delve/cmd/dlv@latest
    ln -s /root/go/bin/dlv /usr/local/bin/dlv

## 查看dlv版本 ##

[root@lys-mysql go]# dlv version
    Delve Debugger
    Version: 1.9.1
    Build: $Id: d81b9fd12bfa603f3cf7a4bc842398bd61c42940 $

## 添加debug方案 ##

修改为远程调试
