Java is an object-oriented programming language, which not only absorbs the advantages of C++ language, but also abandons the concepts of multi-inheritance and pointers which are difficult to understand in C++. Therefore, Java language has the characteristics of powerful and easy to use. Java is a commonly used language environment in CVM. Let's describe how to build java on CVM.

1. Download jdk or jre on the Internet first (just use this on the server)

two。 Then extract the file downloaded by tar and put it under / usr/local/java/jdk_xxx

-v: visually show the progress. Enables verbose mode, showing the progress of the command-x: decompress. Extract-z: use gzip. Uses gzip, omit this if you just have a. Tar-f: specifies the file. Specifies file input, rather than STDIN-C: specify the decompression directory

Export JAVA_HOME=/usr/local/java/jdk1.8.0_202 export PATH=$JAVA_HOME/bin:$PATH

5.source ~ / .bash_profile is finished after the editor takes effect.

The above is how to build a java environment on the CVM. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
