安装Solr PHP JAVA_HOME错误

I'm trying to install Solr PHP via the command line on my server

I'm running the installation with

root@vps25581 [/opt]# ./install_solr_service.sh  solr-6.4.1.tgz

but I keep getting this error:

The currently defined JAVA_HOME (/usr/local/jdk) refers to a location where Java could not be found. Aborting. Either fix the JAVA_HOME variable or remove it from the environment so that the system PATH will be searched.

but when I echo $JAVA_HOME i get: /usr/bin/java

Also when I check the directory /usr/bin/java I can't find any .jdk files or any other files there

How can I find the right location?

/usr/bin/java 

is most likely a symbolic link.

ls -l /usr/bin/java

will show you what it is currently pointing to.

If it needs updated use this command:

ln -sfn <locationOfJDK> /usr/bin/java

to update the symbolic link and attempt to re-install.
