解决git Update(Push )failedunable to access ‘xxx‘: Failed to connect to xxx Connection refused

一般都是因为代理引起的三种解决方案:gitclone拒绝连接,Connectionrefused解决方法一、使用env指令查询系统代理并取消对应http代理二、使用gitconfig指令查询代理并取消代理三、直接修改.gitconfig配置文档查询代理并取消代理gitclone经常出现代理错误,报错如下:fatal:unabletoaccess'':Failedtoconnecttoxxxx:拒绝连接,普遍的解决方案都是取消代理一、使用env指令查询系统代理并取消对应http代理使用指令:env|grep-iproxy会显示系统所有的代理信息:NO_PROXY=localhost,127.0.

docker报错standard init linux.go:228 exec user process caused: exec format error

1、报错使用Dockerfile自己做的服务镜像,dockerrun时启动失败,报错如下:standardinitlinux.go:228execuserprocesscaused:execformaterror2、原因一当前服务器的CPU架构和构建镜像时的CPU架构不兼容。比如做镜像是在arm机器下构建的,而dockerrun是在amd架构下执行的。排查:#镜像信息dockerinspect镜像ID|grep-iArch查看当前服务器的CPU架构信息:#Linux信息uname-a#或lscpu此时,可通过dockerbuildx插件模拟多CPU架构,构建出你需要的镜像,从而解决这个问题。2
