1.首先可以將jdk安裝包上傳到(sftp)linux下或者wget去下載

64bit

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-x64.tar.gz"

32bit

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-i586.tar.gz"

2.解壓縮

 tar -zxvf jdk-7u45-linux-x64.tar.gz -C apps/

3.執行 ./java -version即可檢視版本

./是當期路徑

4.環境變數的配置

linux下的環境變數位置

vim  /etc/profile

5.重新載入環境變數

source  /etc/profile

6.完成
