我是靠谱客的博主洁净枫叶，这篇文章主要介绍linux中用shell快速安装配置Go语言的开发环境，现在分享给大家，希望可以做个参考。

介绍

go1.5+版本提供编译好的安装包，我们只需要解压到相应的目录，并添加一些环境变量的配置即可。

Go语言的安装步骤

下载安装包go1.7.linux-amd64.tar.gz

解压文件到指定目录： tar -zxf go1.7.linux-amd64.tar.gz

设置环境变量：GOROOT, GOPATH, PATH

既然我们可以列出这些步骤，那么便可以将整个过程自动化。

下面是安装脚本

复制代码

#!/bin/bash
#Upgrade go version to 1.7
#wget https://storage.googleapis.com/golang/go1.7.linux-amd64.tar.gz go1.7.tar.gz

function info() {
 echo -e "\033[1;34m$1 \033[0m"
}

function warn() {

}

function error() {
 echo -e "\033[0;31m$1 \033[0m"
}

function usage() {

}

}

 exit 1
fi

if [ ! -d $unzipPath ];
then

 then

 fi
fi

createGoPath $gopath

sudo cp -r "$unzipPath/go" $goroot
rm -rf $unzipPath

then

echo 'export PATH=$GOROOT/bin:$GOPATH/bin:$PATH' | sudo tee -a $etcProfile

# ## Replace multiple empty lines with one empty line
cat $etcProfile -s | sudo tee $etcProfile > /dev/null

info "To make configuration take effect, will reboot, pls enter[y/n]"
read -p "[y/n]" isReboot

then
