Go-Yum Install Go

   Franky    Go    ,

使用 yum 安装 Go

 1[root@itfranky ~]# cat /etc/redhat-release
 2CentOS release 6.5 (Final)
 3[root@itfranky ~]# yum -y install go
 4[root@itfranky ~]# yum list installed | grep -E '^golang'
 5golang.x86_64           1.9.2-1.el6     @epel                                   
 6golang-bin.x86_64       1.9.2-1.el6     @epel

设置环境变量

GOROOT

该环境变量的值为GO语言的当前安装目录，yum安装在/usr/lib/golang目录下。

GOPATH

Go语言的工作区集合,如：$HOME/franky/GoProject

GOBIN

存放Go程序的可执行文件的目录,如：/app/gobin

PATH

Go语言命令和Go程序的可执行文件，需要追加其值PATH=$PATH:$GOBIN

yum安装已经设置了Go语言命令的快捷方式，PATH追加Go程序的可执行文件即可。

1[root@itfranky ~]# ls /usr/bin/go -ltr
2lrwxrwxrwx 1 root root 20 Jan 11 20:07 /usr/bin/go -> /etc/alternatives/go
3[root@itfranky ~]# 
4[root@itfranky ~]# ls /etc/alternatives/go -ltr
5lrwxrwxrwx 1 root root 22 Jan 11 20:07 /etc/alternatives/go -> /usr/lib/golang/bin/go
6[root@itfranky ~]# 
7[root@itfranky ~]#

编辑/etc/profile文件

追加：

1#set go environment
2 
3export GOPATH=$HOME/franky/GoProject
4export GOBIN=/app/gobin
5export PATH=$PATH:$GOBIN

然后执行 source /etc/profile 使之生效。

 1[root@itfranky franky]# mkdir -p /app/gobin
 2[root@itfranky franky]# mkdir -p ~/franky/GoProject
 3[root@itfranky franky]# source /etc/profile
 4[root@itfranky franky]# go env
