很简单的一段代码，go运行一个http服务： {代码...} 编译的时候系统日志(/var/log/message)： {代码...} 机器是Aliyun & CentOS 6.3 64bit & 512M & 1G swap，之前编译其他go代码的时候也发生过这种...

linux - golang编译报错(go build command-line-arguments: signal: killed)-PHP Chinese Network Q&A

很简单的一段代码，go运行一个http服务：

package main

import (
    "io"
    "log"
    "net/http"
)

func helloHandler(w http.ResponseWriter, r *http.Request) {
    io.WriteString(w, "Hello, world!")
}

func main() {
    http.HandleFunc("/hello", helloHandler)
    err := http.ListenAndServe(":8080", nil)
    if err != nil {
        log.Fatal("ListenAndServe: ", err.Error())
    }
}

编译的时候系统日志(/var/log/message)：

机器是Aliyun & CentOS 6.3 64bit & 512M & 1G swap，之前编译其他go代码的时候也发生过这种情况，但是我设置过swap文件之后就可以了。现在不知道怎么解决了。

低端机器连基本代码都不让编译了么555

Your compiler failed because of insufficient memory. OOM may cause the kernel to crash. In fact, your kernel has already crashed.

But can't you compile it locally and then upload it to the server? Why compile directly on the server?
Golang's resource consumption is still quite high. Even if you have compiled it, you feel that memory may be exhausted during runtime.
Suggestion:
1) free -m to check the remaining memory. If swap is not enough, it will definitely not work
2) Kill some processes that occupy resources, if they are not system processes
