[root@cs7 java]# wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u152-b16/aa0333dd3019491ca4f6ddbe78cdb6d0/jdk-8u152-linux-x64.

[root@cs7 java]# chmod +x jdk-8u152-linux-x64.rpm
[root@cs7 java]# ll
-rwxr-xr-x. 1 root root 174192082 10月 10 06:05 jdk-8u152-linux-x64.rpm

[root@cs7 java]# rpm -ivh jdk-8u152-linux-x64.rpm
