centos6 安装go框架gin的步骤，以及中间遇到的坑

我的环境是centos 6，安装go语言的文档参看：

centos6 – 安装 golang 1.9

安装完go语言后，安装gin框架，github地址为：https://github.com/gin-gonic/gin

通过readme的介绍，通过命令行安装：

go get github.com/gin-gonic/gin

结果发现，一直卡住，无法通过go get完成安装，最后查阅了资料发现是git版本的问题，参看：https://github.com/go-playground/validator/issues/224#issuecomment-165324546

然后我重新安装了git，参看文档：

centos6 安装 git2.7

然后，重新执行安装

[root@iZ942k2d5ezZ go]# go get -v  github.com/gin-gonic/gin

[root@iZ942k2d5ezZ go]# 

然后，创建g3.go文件，内容如下：

package main

import "github.com/gin-gonic/gin"

func main() {
        r := gin.Default()
        r.GET("/ping", func(c *gin.Context) {
                c.JSON(200, gin.H{
                        "message": "pong",
                })
        })
        r.Run("120.24.37.249:3000") // listen and serve on 0.0.0.0:8080
}

注意：

1.ip换成您自己的ip

2.iptables 开放3000端口

/sbin/iptables -I INPUT -p tcp --dport 3000 -j ACCEPT
/etc/rc.d/init.d/iptables save

 

执行Log

[root@iZ942k2d5ezZ golang]# go run g3.go

[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.

访问：http://120.24.37.249:3000/ping

页面返回：

OK，成功。
