1.完全卸载golang
查看路径在哪里：

which go

root 权限下删除

rm -rf /usr/local/go

2.安装golang
下载golang包

wget https://golang.google.cn/dl/go1.16.linux-amd64.tar.gz

解压到usr/local下

tar -C /usr/local/ -zxvf go1.16.linux-amd64.tar.gz

修改配置文件（系统配置为/etc/profile，用户配置为~/.profile），这里就修改系统配置

sudo vim /etc/profile

在文件最后加上两行（如果有旧版本的go配置就不用加，或者要修改路径）

export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin

执行使配置文件生效

source /etc/profile

查看go版本

go version

本来准备直接yum install golang或者yum install go， 执行命名后，发现没有这个包。于是只能先添加源，然后在使用命令行安装了。
