This section describes how to integrate Apache with Tomcat 4 under RedHat Linux 7.2, focuses on how to create mod_webapp.so, and how to configure, manage, and apply it in a virtual host environment, the test has been successful. I hope it will help you. please correct me if you have any errors.
　　
　　
1. install Tomcat 4 correctly
Install necessary software as follows:
1. Java SDK
For version 1.3.1 or 1.4, it is recommended to install it in/usr/java and create a soft link for jdk.
If there is a problem installing SDK 1.3.1, read the documentation: http://java.sun.com/j2se/1.3/install-linux-sdk.html
2. Tomcat4
We recommend that you install the binary file installation package of the latest release version. The latest tomcat version is 4.1.12.
:
Http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.12/bin/jakarta-tomcat-4.1.12.tar.gz
Download and press to a directory "tar xvzf jakarta-tomcat-4.1.12.tar.gz"
In this example, tomcat is installed in the/opt directory and a soft link of tomcat is made.
Set and enable the following environment variables:
PATH = $ PATH:/usr/java/jdk/bin:/usr/java/jdk/jre/bin
JAVA_HOME =/usr/java/jdk
Export JAVA_HOME
CLASSPATH = "./:/usr/java/jdk/lib:/usr/java/jdk/jre/lib"
Export CLASSPATH
CATALINA_HOME =/opt/tomcat
Export CATALINA_HOME
　　
We recommend that you create a single user tomcat, set it to the owner of all Directory files under/opt/tomcat, and start tomcat by it:
# Useradd tomcat
# Chown-R tomcat: tomcat/opt/tomcat
# Su-tomcat-c "/opt/tomcat/bin/startup. sh"
　　
Visit http: // localhost: 8080/to see the successful tomcat installation page.
　　
　　
========================================================== ======================================
If you want to integrate with apache, you need to modify the tomcat/conf/server. xml file

II. Integration of Apache and Tomcat 4
　　
1. first install Apache,
Note that DSO mode must be installed in Apache, that is, -- enable-module = so must be added when you execute./configure.
　　
Installed in the/usr/local/apache directory by default. The apache version installed in this example is 2.0.43 series.
　　
2. create mod_webapp.so
The following software packages are required:
Jakarta-tomcat-connectors-4.x.xx-src.tar.gz
In the src Directory of the tomcat version. For example, if the tomcat version I installed is 4.1.12, the required software package is located:
Http://jakarta.apache.org/builds/ja...1.12-src.tar.gz
Apr-0.9.1.tar.gz
: Http://www.apache.org/dist/apr/apr-0.9.1.tar.gz
Autoconf-2.52-ximian.1.i386.rpm
: Http://rpmfind.net/linux/RPM/helix/...ian.1.i386.html
First use rpm to install the autoconf-2.52, because the following installation will be used;
Then open jakarta-tomcat-connectors-4.1.12-src.tar.gz and generate the jakarta-tomcat-connectors-4.1.12-src directory,
Go to the jakarta-tomcat-connectors-4.1.12-src/webapp's directory and remove apr-0.9.1.tar.gz to this directory,
And change the directory name of the directory apr-0.9.1 just generated to apr.
In the webapp Directory, run the following command:
# Support/buildconf. sh
In this case, if autoconf is earlier than 2.52, an error is reported and exited, so you must install the autoconf-2.52 first.
After the command is completed successfully, the configure file is generated in the current directory.
Run the following commands in sequence:
　　
#./Configure -- with-apxs =/usr/local/apache/bin/apxs
# Make
# Cp apache-2.0/mod_webapp.so/usr/local/apache/modules
　　
Now mod_webapp.so has been created and copied to the modules directory of apache.
Edit the apache configuration file and add the following lines at the end:
======================================
LoadModule webapp_module modules/mod_webapp.so
WebAppConnection Connector warp localhost: 8008
WebAppDeploy examples Connector/examples
======================================
　　
Run the following command:
#/Usr/local/apache/bin/apachectl configtest
　　
If an error occurs, the following error occurs: "inviad virual host"
　　
It means that the ServerName of your httpd. conf is not set. remove "#" before the ServerName! (This is the answer only after a lot of information is provided. I am also confused here for many days)
　　
"Syntax OK" indicates that mod_webapp.so has been installed successfully.
Start apache
#/Usr/local/apache/bin/apachectl start
Visit http: // localhost/examples to see the tomcat example program.
　　
Note: you must first start tomcat and then restart apache!
　　
III. configuration, management, and application under virtual hosts
　　
The following uses an example to describe how a VM uses Apache and Tomcat 4 at the same time.
　　
The directory structure of host1 is as follows:
　　
　　
/Www
| --- Main directory of host1
| -- Htdocs common root directory: used to display static pages or php programs
| ---- Logs apache access log
| ---- Webapps java Application Directory (newly added, not associated with tomcat's webapps directory)
| -- ROOT jsp ROOT directory: used to display jsp page programs
| ---- Jive a set of java application instances
| --- Main directory of host2
............
　　
　　
　　
The original apache configuration file is configured as follows:
　　
　　
============================================
NameVirtualHost xxx. xxx
　　
<VirtualHost xxx. xxx>
ServerName host1.mydomain.com
ServerAdmin webmaster@mydomain.com
DocumentRoot/www/host1/htdocs
ErrorLog/www/host1/logs/error_log
CustomLog/www/host1/logs/access_log common
</VirtualHost>
.............
　　
============================================
　　
　　
　　
To enable the virtual host host1 to use Apache and Tomcat 4 at the same time, you need to configure the following:
　　
1. edit the tomcat configuration file server. xml and make the following changes in the last part:
　　
　　
============================================
<! -- Define an Apache-Connector Service -->
　　
<Service name = "Tomcat-Apache">
　　
<Connector className = "org. apache. catalina. connector. warp. WarpConnector"

<Context path = "" docBase = "ROOT" debug = "0"/>
<! -- The following is a built-in tomcat management page, which can also be used under a VM -->

DocBase = "/opt/tomcat/server/webapps/manager"/>
