安装GoLang

1. 下载解压安装

   cd /root
   wget https://dl.google.com/go/go1.14.1.linux-amd64.tar.gz
   tar -zxvf go1.14.1.linux-amd64.tar.gz
   mv /root/go /usr/local/go
   

2. 加入环境变量

   vim /etc/profile
   
   export PATH=$PATH:/usr/local/go/bin
   
   ESC
   :wq
   
   source /etc/profile
   

3. 目录权限

   chown -R www:www /usr/local/go
   

4. 测试是否安装成功

   su www
   go env
   

使用框架Gin

1. 准备工作

   su www
   go env|grep GOPATH
   # 显示 GOPATH="/home/www/go"
   
   mkdir /home/www/go/src/golang.org/x
   cd /home/www/go/src/golang.org/x
   
   git clone https://github.com/golang/sys.git
   git clone https://github.com/golang/net.git
   git clone https://github.com/golang/text.git
   git clone https://github.com/golang/lint.git
   git clone https://github.com/golang/tools.git
   git clone https://github.com/golang/crypto.git
   

2. 获取框架

   su www
   mkdir /www
   cd /www
   go get -u github.com/gin-gonic/gin
   

3. 使用框架

   //参考 https://github.com/gin-gonic/gin/blob/master/README.md
   package main
   
   import "github.com/gin-gonic/gin"
   
   func main() {
       route := gin.Default()
   
       route.GET("/", func(c *gin.Context) {
           c.JSON(200, gin.H{
               "code": 200,
               "data": [0]int{},
               "msg": "/",
           })
       })
   
       route.GET("/:path", func(c *gin.Context) {
           path := c.Param("path")
           c.JSON(200, gin.H{
               "code": 200,
               "data": [0]int{},
               "msg": path,
           })
       })
       route.Run("0.0.0.0:8000")
   }
