lrwxrwxrwx 1 root root 22 Mar 15 09:59 /usr/bin/java -> /etc/alternatives/java
[root@localhost bin]# ls -lrt /etc/alternatives/java            ***
lrwxrwxrwx 1 root root 73 Mar 15 09:59 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/jre/bin/java
[root@localhost bin]# cd /usr/lib/jvm        ***
[root@localhost jvm]# ll
total 4
drwxr-xr-x 3 root root 4096 Mar 15 09:59 java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64
lrwxrwxrwx 1 root root   21 Mar 15 09:59 jre -> /etc/alternatives/jre
lrwxrwxrwx 1 root root   27 Mar 15 09:59 jre-1.8.0 -> /etc/alternatives/jre_1.8.0
lrwxrwxrwx 1 root root   35 Mar 15 09:59 jre-1.8.0-openjdk -> /etc/alternatives/jre_1.8.0_openjdk
lrwxrwxrwx 1 root root   51 Mar 15 09:59 jre-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64 -> java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/jre

export JRE_HOME=$JAVA_HOME/jre
