go环境变量配置 (GOROOT和GOPATH)

1、GOROOT就是go的安装路径。在/etc/profile文件中加上GOROOT

[root@localhost ~]# vim /etc/profile
export GOROOT=/usr/local/go
export PATH=/usr/local/nginx/sbin:/usr/local/mysql/bin:$GOROOT/bin:$PATH
[root@localhost ~]# source /etc/profile

2、GOPATH就是你工作项目的路径。在/etc/profile文件中加上GOPATH

[root@localhost ~]# vim /etc/profile
export GOROOT=/usr/local/go
export GOPATH=/data/wwwroot/beego
export PATH=/usr/local/nginx/sbin:/usr/local/mysql/bin:$GOROOT/bin:$GOPATH/bin:$PATH
[root@localhost ~]# source /etc/profile

3、下载安装

[root@localhost wwwroot]# go get github.com/astaxie/beego 
[root@localhost wwwroot]# ll
total 0
drwxr-xr-x 4 root root 26 Jul 28 17:40 beego
drwxr-xr-x 2 www  www  23 Jul 28 16:05 default

备注：GOROOT、GOPATH路劲必须是绝对路径。（操作以上命令在一个窗口下执行，否则下载时会出错。）
