This article is about how centos finds installed jdk paths. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

When the java command is executable, the lookup process is as follows:

Execute which java

[root@localhost ~] # which java/usr/bin/java

Execute ls-lrt / usr/bin/java

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

Execute ls-lrt / etc/alternatives/java

[root@localhost] # ls-lrt / etc/alternatives/javalrwxrwxrwx. 1 root root 73 October 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

As can be seen from the above, 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 total dosage 4drwxr-xr-x. 2 root root 4096 October 10 14:53 bindrwxr-xr-x. 3 root root 132 October 10 14:53 includedrwxr-xr-x. 4 root root 28 October 10 08:03 jredrwxr-xr-x. 3 root root 144October 10 14:53 libdrwxr-xr-x. 2 root root 204Oct 10 14:53 tapset [root@localhost java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64] # Thank you for reading!
