Go fork / exec权限被拒绝错误 [英] Go fork/exec permission denied error

问题描述

我最近使用CentOS 6.3将Go安装到我们的服务器上。安装似乎没有问题。然而，我做了一个测试hello world脚本，当我运行时，我得到了下面的输出。

$ p $ fork $ / $ /go-build967564990/command-line-arguments/_obj/a.out：权限被拒绝

现在正在运行去env或其他go命令似乎工作。起初，我认为这是一个权限问题，然而，作为root用户运行我得到同样的事情。一个

解决方案

只是猜测：你的nix可能因安全原因在/ tmp中执行程序而被禁用。它可能可以在CentOS中配置，但我不知道。

另一种解决方案：看来你正在尝试 go run code>来执行一个Go程序（这与C脚本一样是一个脚本）。尝试（假设 $ GOPATH =〜，简单的可能性），而不是正常的构建，而不是



  me：〜/ src / foo $ go run main.go 
  

试试

  me：〜/ src / foo $ go build＃main.go在这里不需要
 me：〜 / src / foo $ ./foo 
  

这种方法仍然使用/ tmp-whatever来创建二进制文件，IIRC，但它不会尝试从那里执行。

PS：不要以root身份运行这些命令。没有必要使用正确的设置。

I recently installed Go onto our server with CentOS 6.3. The install appears to have gone fine. However I made a test "hello world" script, and when I run I get the following output.

fork/exec /tmp/go-build967564990/command-line-arguments/_obj/a.out: permission denied

Now running go env or other go commands seem to work. At first I figured it was a permission issue, however running as root user I get the same thing. An

解决方案

Just guessing: Your nix perhaps disables for security reasons executing programs in /tmp. It might be configurable in CentOS, but I don't know that.

The alternative solution: It seems you're trying go run to execute a Go program (which is as script as C is a script). Try (assuming $GOPATH=~, the easy possibility) instead a normal build, i.e. instead of

me:~/src/foo$ go run main.go

try

me:~/src/foo$ go build # main.go should not be necessary here
me:~/src/foo$ ./foo

This approach will still use /tmp-whatever to create the binary, IIRC, but it will not attempt to execute it from there.

PS: Do not run these command as root. No need for that with correct setup.
