Installing Go on CentOS 5.x
问题
我想在CentOS 5.x上安装Go，但是Go的网站http://golang.org/doc/install提到它不支持该版本。
由于CentOS只是Linux的一个不同版本，是否仍然有办法在CentOS上安装Go语言？
当我安装相同的版本并运行上述网站中提到的示例程序hello.go时，我遇到了错误
hello.go:3:8: import "fmt": cannot find package
package runtime: import "runtime": cannot find package
英文:
I want to install Go on CentOS 5.x, but Go website here http://golang.org/doc/install mentions that it is not supported.
Is there still some way to install Go Language on CentOS since CentOS is just a different flavour of Linux?
When I installed the same and ran the sample program hello.go mentioned at above website
I got the error
hello.go:3:8: import "fmt": cannot find package
package runtime: import "runtime": cannot find package

找不到“runtime”包告诉您$GOROOT环境变量未设置为golang根目录。您需要设置$GOROOT。如果您使用外部包，还应该设置$GOPATH变量（有关更多信息，请参见go help gopath）。
一个典型的设置（不特定于CentOS）可能是：
export GOROOT="/usr/local/go"
export PATH="$GOROOT/bin:$PATH"
export GOPATH=/Users/rodowi/gocode
英文:
% export GOROOT=~/
% go run test.go
test.go:3:8: import "fmt": cannot find package
package runtime: import "runtime": cannot find package
Not finding the "runtime" package tells you that the $GOROOT enviroment variable isn't set to golang root directory.
You need to set $GOROOT. Also you should set the $GOPATH variable if you use external packages (go help gopath for more information).
A typical setup (not specific to CentOS) would be:
export GOROOT="/usr/local/go"
export PATH="$GOROOT/bin:$PATH"
export GOPATH=/Users/rodowi/gocode

至少对于一些程序来说，它运行得很好。我有一个在RHEL 6.x上编译并部署在5.x和6.x上的生产程序，它没有任何问题。
编辑：我过去使用的是1.0.3版本，但几个月前我升级到了“tip go”（即将发布的1.1版本）。在1.x版本下，当接受一个TCP连接时，它会在5.9上崩溃，但在我在邮件列表上报告后的几天内就修复了这个问题。
英文:
At least for some programs it works fine. I have a production program that I compile on RHEL 6.x and deploy on 5.x and 6.x and it is working without any problems.
Edit: I used to use it under 1.0.3, but a few months ago I upgraded to "tip go" (the soon to be 1.1 version). Under 1.x it'd crash on 5.9 when accepting a tcp connection but that was fixed a few days after I reported it on the mailing list.

这个页面很好地解释了CentOS-5内核缺少的内核原语，它们的影响以及可能的修复方法。

This page explains rather well what kernel primitives are missing from the CentOS-5 kernel, their impact, and possible fixes.

我很抱歉，由于CentOS 5.x内核版本过旧，你可能运气不佳。如果Go运行时使用的功能在该内核中根本不存在，那么我看不到它能够正常工作的简单方法。
英文:
I'm affraid you're out of luck because of the bit too much aged kernel version of CentOS 5.x. If the go runtime uses features simply not present in that kernel, then I see no easy way how it could work.

你可以下载rpm包并在本地安装，根据你的操作系统选择以下链接进行下载：
http://pkgs.org/download/golang
或者你也可以选择从源代码编译和构建：

英文:
you could download the rpm package and begin installing locally, check below and download according to your OS:
http://pkgs.org/download/golang
or you could alternatively compile and build from source:
