Go 語言環境安裝

• 下載安裝包ofollow,noindex">https://golang.google.cn/dl/
• CentOS安裝為例：

1、下載原始碼包：go1.4.linux-amd64.tar.gz。
2、將下載的原始碼包解壓至 /usr/local目錄。
tar -C /usr/local -xzf go1.4.linux-amd64.tar.gz
3、配置GOPATH、GOROOT環境變數：
vi /etc/profile新增以下幾行在檔案末尾
export GOROOT=/usr/local/go
export GOPATH=/home/www/go
export PATH=$PATH:$GOROOT/bin
儲存退出
source /etc/profile立即生效

• 這個時候輸入以下命令就能看到安裝配置完成

[root@10-23-67-69 bin]# go version
go version go1.11 linux/amd64

[root@10-23-67-69 bin]# go help
