解决解压JDK报错：tar: Error is not recoverable

报错

#tar -xvf jdk-8u131-linux-x64.tar.gz，执行命令后报错如下：
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

完美解决

在wget后添加一下
 --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie"
命令如下：
wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie"  “你需要下载的东西”
