go語言環境搭建(基於go1.8)

• Linux(centos redhat ) 安裝
  1.訪問官方地址：
  https://golang.org/dl/
  由於相關ZC你懂的，最好能翻牆下
  2.下載64位綠色包：
  https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
  3.下載完畢後：
  假定你想要安裝Go的目錄為$GO_INSTALL_DIR，後面替換為相應的目錄路徑。
  解壓縮tar.gz包到安裝目錄下:

tar -xvf go1.8.3.linux-amd64.tar.gz -C $GO_INSTALL_DIR

4.添加環境變數vim /etc/profile,加入如下幾行

export PATH=$PATH:$GO_INSTALL_DIR/go/binexport GOROOT= $GO_INSTALL_DIR/goexport GOBIN=$GOROOT/binexport GOPATH= $GO_INSTALL_DIR/go/data  注意 $GO_INSTALL_DIR 為你的go的安裝或者解壓目錄

• 然後執行go
