Install JDK1.8 under Ubuntu Kylin, the reference address is: http://jingyan.baidu.com/article/647f0115bb26817f2048a871.html, in addition to referring to it, the steps are as follows:
Note: I placed jdk in the /opt/duan/ directory
The following steps 1~6 are all operated by ordinary users
1、 First download the JDK for linux, not to mention the specific download process.
2、 Unzip and copy the jdk to the /opt/duan directory: tar zxvf jdk1.8...-linux-64...tar.gz -C /opt/duan
3、 Switch the shell current directory to /opt/duan, modify the name of the jdk folder: mv jdk1.8.0_05 jdk1.8
4、 gedit /home/duan/.bashrc (note that duan is my username)
5、 Write the content shown in the figure below into the file:
6、5 After the steps, save the file, close the file, and then enter java -version in the shell to see the jdk version.

1、 Switch to the root user.
2、 After executing gedit /etc/profile, write the content in the following figure to the file:
