centos7的golang安装和goland安装

（
额外知识，可以不了解
linux的3种环境变量，1针对所有用户永久的，2针对单一用户永久的，3临时的，具体看
https://www.cnblogs.com/qiuhong10/p/78159
）

https://studygolang.com/dl
在上面地址下载golang安装包

下载后的压缩包移动到/usr/local
解压缩
tar -xvf xxx.tar.gz

将/usr/local/go/bin添加到PATH环境变量中
切换到root用户，编辑/etc/profile
vi /etc/profile
在最底部添加
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

// go安装目录
export GOROOT=/usr/local/go
// 项目工作目录，可以设置多个，用 : 隔开
export GOPATH=/xx1/gowork:/xx2/gowork
保存退出，修改文件后要想马上生效还要运行
source /etc/profile，不然只能在下次重进此用户时生效

$PATH 可以查看环境变量设置

go version  看到go的安装版本即安装成功

• goland安装
  到goland官网下载对应版本的goland，https://www.jetbrains.com/go/
  下载破解文件JetbrainsCrack.jar
  链接：https://pan.baidu.com/s/1Nipe60NlYs3Zpu5_kG-ovw
  提取码：9axa

压缩包解压缩到/usr/local/目录下
复制 JetbrainsCrack.jar 到 安装目录 / bin文件夹中
使用记事本编辑GoLand.vmoptions，GoLand64.vmoptions这两个文件，在最后加上
-javaagent:/usr/local/GoLand/bin/JetbrainsCrack.jar
路径地址根据自己的实际路径填写，比如我的goland放在/usr/local/GoLand，两个文件都要加上，保存退出

在bin目录下，用命令 ./goland.sh 启动goland
注册时选择active code，输入以下激活码激活，如果激活码不能用了就在网上再随便找个

该方法使用破解任何平台的goland，把-javaagent: 后面的路径填对就行

• 启动后页面如下
  在file--setting 做些设置
  

设置go modules，勾选enavle gomodules，代理：https://goproxy.io
proxy为代理：执行程序时若缺少依赖包，将去代理地址拉取，不代理的话有些包会被墙，这个代理地址是开源的项目，不被墙且速度很快

在tool--file watchers添加go fmt命令，保存代码时会自动格式化代码格式
