General overview
The Tomcat class has three modes of operation, and when Tomcat is used as a "standalone servlet container", Tomcat starts and stops by executing a script in the bin directory.

Using the unpacked Tomcat package, the command line input service Tomcat start will report the tomcat:unrecognized service error, meaning that the system did not find the service.Well, the problem that we are going to solve now is this error hint, let our decompression install version of Tomcat can also support the Yum installation mode of the service

Find setclasspath. sh in bin and add the following code at the beginning of the file:
set JAVA_HOME=/home/jdk/Java\jdk7\jdk1.7.0_51set JRE_HOME=/home/jdk/Java\jdk7\jre7
After the setclasspath file is modified, tomcat uses the set JDK at startup.
But why is it possible after this setting?
