This article will explain in detail how to achieve one-click installation of JDK in linux. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Linux script making

Installjdk script content: export LANG=en_USmkdir-p / usr/local/javatar zxvf jdk-8u201-linux-x64.tar.gz-C / usr/local/javacat / opt/install/java > > / etc/profilesource / etc/profile

The command in the file explains:

Create the jdk installation directory: mkdir-p / usr/local/java

Decompress jdk package: tar zxvf jdk-8u201-linux-x64.tar.gz-C / usr/local/java

Copy the jdk environment variable configuration to the system environment variable configuration file: cat / opt/install/java > > / etc/profile

Refresh the system environment variable configuration file: source / etc/profile

Java script content: export JAVA_HOME=/usr/local/java/jdk1.8.0_201/export JRE_HOME=/usr/local/java/jdk1.8.0_201/jreexport PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATHexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib:$JRE_HOME/lib

File is configured for the JDK environment variable.

Script executes operation steps

① create a new / opt/install directory (as long as the path is the same in the script)

② throws installjdk (installation script), java (environment variable configuration script), jdk-8u201-linux-x64.tar.gz (installation package can also be other versions of JDK) into the / opt/install directory

③ gives executable permissions to installjdk scripts

Chmod uplix / opt/install/installjdk

④ executes script to install jdk

/ opt/install/installjdk

⑤ executes the following command to check whether jdk is installed successfully

Java or java-version or javac check whether jdk is installed successfully
