Run two tomcat configurations at the same time

It programmer development must-all kinds of resources download list, the most complete IT resources in history, personal collection summary.

can be used. Please follow the procedure in everyone.

However, more than two, you will also change the port number.

1 Download Tomcat's compression pack (not the one that is installed, which can be used for direct decompression)
Download Address: http://tomcat.apache.org/download-55.cgi
Download a good filename is: apache-tomcat-5.5.23.zip

2 decompression. I unpacked it to C:\.
C:\apache-tomcat-5.5.23-1,c:\apache-tomcat-5.5.23-2, respectively.

3 Modifying any one of the configuration files
Like Apache-tomcat-5.5.23-1,
C:\apache-tomcat-5.5.23-1\conf\server.xml, open with Notepad or something.
Modify 3 Places

First:
<server port= "9005" shutdown= "shutdown" >----it turns out to be 8005.
Second
<connector port= "9080" maxhttpheadersize= "8192"----it turns out to be 8080.
The third <connector port= "9009" enablelookups= "false" redirectport= "8443" protocol= "ajp/1.3"/>---Turns out to be 8009.

and then save

4 Open the first Tomcat
Run-cmd
Set two environment variables: java_home (pointing to JDK) and catalina_home (pointing to the Tomcat directory)
At the command line: set Java_home=c:\program files\java\jdk1.5.0_11
Set Catalina_home=c:\apache-tomcat-5.5.23-1
Can run Tomcat, command: C:\apache-tomcat-5.5.23-1\bin\startup.bat
(Close can use C:\apache-tomcat-5.5.23-1\bin\shutdown.bat)

4 Start a second tomcat
Run-cmd (another command window is open)
Or do you want to set two environment variables: java_home (pointing to JDK) and catalina_home (pointing to the Tomcat directory)
At the command line: set Java_home=c:\program files\java\jdk1.5.0_11
Set Catalina_home=c:\apache-tomcat-5.5.23-2 (note the Tomcat directory I pointed to another)
Can run Tomcat, command: C:\apache-tomcat-5.5.23-2\bin\startup.bat Note is also another--5.5.23-2)
(Close can use C:\apache-tomcat-5.5.23-2\bin\shutdown.bat) (note also another--5.5.23-2)

Complete

Note:
Possible errors:

1 command-line hint: The CATALINA_HOME environment variable is not defined correctly
               This environment variable are needed to run this program
translation: this Catalina_ The home environment variable is not correctly defined
      This program needs to be run by this environment variable
to resolve: Set Catalina_home with my top set command

2 Command prompt: 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
Translation: Java_home or jre_home environment variable any one is undefined
This program needs at least one environment variable to run (both)
Workaround: Set Java_home with my top set command
3 Command prompt: The JAVA_HOME environment variable is not defined correctly
This environment variable are needed to run this program
Nb:java_home should point to a JDK not a JRE
Translation: Java_home environment variables are not properly defined
This program requires this environment variable to run
Java_home should point to JDK rather than JRE
Workaround: Set Java_home with my top set command, and be sure to point to the JDK directory

4 about the modified port number: As long as it is not a common port number, do not set the common port number
The bottom is more common, do not set these on the line of basic 9,000 more no one uses
