(recommended tutorial: centos Tutorial)

2. Execute ls -lrt /usr/bin/java

[root@localhost ~]# ls -lrt /usr/bin/java
lrwxrwxrwx. 1 root root 22 10月 10 08:06 /usr/bin/java -> /etc/alternatives/java

3. Execute ls -lrt /etc/alternatives/java

[root@localhost ~]# ls -lrt /etc/alternatives/java
lrwxrwxrwx. 1 root root 73 10月 10 08:06 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64/jre/bin/java

It can be seen from the above that the path of java is: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64. Enter the path to view the file as follows:

[root@localhost ~]# cd /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64
[root@localhost java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64]# ll
