tomcat-installation Configuration

0. Download:
Download the latest version of tomcat:http://tomcat.apache.org/download-60.cgi from the official website to find the appropriate version.
According to the computer system version, I downloaded the apache-tomcat-8.0.20-windows-x86.zip
Unzip directly onto the D-disk, the directory is apache-tomcat-8.0.20

1. Run:
Find the D:\apache-tomcat-8.0.20\bin under the Startup.bat flash immediately, not see the relevant content.
Use CMD to see the relevant informational hints:
Microsoft Windows [version 6.1.7600]

C:\users\an>d:

D:\>CD Apache-tomcat-8.0.20\bin

D:\apache-tomcat-8.0.20\bin>startup.bat
Neither the Java_home nor the JRE_HOME environment variable is defined
At least one of these environment variable are needed to run this program
D:\apache-tomcat-8.0.20\bin>

The JDK was already installed on the computer and the relevant environment variables were configured.

2. Configuration:
Right-click Computer--"Properties----" Advanced system Settings---"Enter the environment variable
In the system variable, create a new project
Variable name: corresponding variable value:
Java_home C:\Program files\java\jdk1.8.0_31
Jre_home C:\Program files\java\jre1.8.0_31


3. Run the test:
In the second with CMD to see the relevant information prompt:
Microsoft Windows [version 6.1.7600]

C:\users\an>d:

D:\>CD Apache-tomcat-8.0.20\bin

D:\apache-tomcat-8.0.20\bin>startup.bat
Using catalina_base: "D:\apache-tomcat-8.0.20"
Using catalina_home: "D:\apache-tomcat-8.0.20"
Using catalina_tmpdir: "D:\apache-tomcat-8.0.20\temp"
Using jre_home: "C:\Program files\java\jre1.8.0_31"
Using CLASSPATH: "D:\apache-tomcat-8.0.20\bin\bootstrap.jar;d:\apache-tomcat-8.0.20\bin\tomcat-juli.jar"
D:\apache-tomcat-8.0.20\bin>
Then the Tomcat runtime window is displayed normally:

At this point, the Java JDK and Tomcat environments are configured to complete
After the configuration is complete to determine if the configuration is successful, the following steps
1 verifying that the Java JDK is configured successfully
Enter the console input Java If "Java" is not an internal or external command and is not a running program or batch file, the configuration is not successful. Conversely, if Java-related things happen, it means success.
2. Verify that Tomcat is configured successfully
Go to the Bin directory of Tomcat, locate Startup.bat, double-click Run, if one disperses, it may not be configured successfully (further determine, enter localhost:8080 or 127.0.0.1 in the Web address bar) : 8080, if no response is not configured successfully), otherwise the configuration is successful
