Where is the linux jdk directory?

linux view jdk installation directory

1. jdk installed by installation package

If you are installing the current installation package, you will generally configure the environment variables

echo $JAVA_HOME

or view /etc/profile

vi /etc/profile

2. yum installation View the installation directory

I am lazy, so I installed it using yum.

## First find the execution directory of javad

whereis java

Find the link file through the execution file

ls -lrt /usr/bin/java

cd /etc/alternatives/ found that it is not the source file, continue to find it through the link file

ls -lrt /etc/alternatives/java

 cd /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64-debug/jre/bin

ok, the installation directory has been found.
