Linux--Integration of Web server configuration Apache and Tomcat

First, integrating Apache and Tomcat

Although Tomcat can run independently as a Web server, Tomcat's web capabilities are far from Apache, so in practice, Apache and Tomcat are integrated with the service through the MOD_JK Connector (connectors), Apache handles requests for static pages, and Tomcat handles Servlets and JSP programs.

1. Download MOD_JK

Currently the latest stable version of the MOD_JK connector is 1.2.23, accessed using a Web browser http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/ jk-1.2.23/, click the "mod_jk-1.2.23-apache-2.2.x-linux-i686.so" hyperlink on the page, download the MOD_JK, and the file size is approximately 589kb,7-34.

2. Installing and configuring MOD_JK

Copy the mod_jk-1.2.23-apache-2.2.x-linux-i686.so to the/etc/httpd/modules directory and rename it to mod_jk.so.

Create a new subdirectory in the/usr/share/tomcat5/conf directory JK, and create a new file Workers.properties, as follows.

workers.tomcat_home=/usr/share/tomcat5workers.java_home=/usr/lib/jvm/javaps=/worker.list= Ajp13worker.ajp13.port=8009worker.ajp13.host=127.0.0.1worker.ajp13.type=ajp13worker.ajp13.lbfactor=1

Modify the/usr/share/tomcat5/conf/server.xml file to add statements under <engine name= "Catalina" defaulthost= "localhost" > statements < Listener classname= "Org.apache.jk.config. Apacheconfig "modjk="/etc/httpd/modules/mod_jk.so "/>,7-35 shown.

Restart the Tomcat service, and the directory/usr/share/tomcat5/conf/auto and file/usr/share/tomcat5/conf/auto/mod_jk.conf will be generated automatically. Copy the file/usr/share/tomcat5/conf/auto/mod_jk.conf to the/USR/SHARE/TOMCAT5/CONF/JK directory and rename it to Mod_jk.conf-auto.

Modify the Mod_jk.conf-auto file and modify the contents as follows.

<ifmodule!mod_jk.c>loadmodule jk_module "/etc/httpd/modules/mod_jk.so" </ifmodule>jkworkersfile "/usr/ Share/tomcat5/conf/jk/workers.properties "Jklogfile"/usr/share/tomcat5/logs/mod_jk.log "JkLogLevel emerg< VirtualHost *:80>servername localhostjkmount/*.jsp ajp13</virtualhost>

3. Configure Tomcat

To achieve Apache and tomcat consolidation, it is necessary to set the home directory for Apache and Tomcat to be consistent. Since Tomcat's default home directory is/var/lib/tomcat5/webapps/root, you should edit Tomcat's master profile/usr/share/tomcat5/conf/server.xml to find the following statement:

After that, add the following statement:

<context path= "" docbase= "/var/www/html" debug= "0"/>
This indicates that the configuration of the Tomcat home directory is shown in/var/www/html/,7-36.

4. Configure Apache
Edit the file/etc/httpd/conf/httpd.conf and add the following statement at the end of the file:
Include/usr/share/tomcat5/conf/jk/mod_jk.conf-auto
5. Restarting Apache and Tomcat
Because the configuration files for Apache and Tomcat are modified separately using the MOD_JK connector, you need to restart Apache and Tomcat using the following command.
/ETC/INIT.D/HTTPD restart/etc/init.d/tomcat5 Restart
6. Test Apache and Tomcat integration
Create a file named test.jsp in the home directory/var/www/html/with the following contents:
Hello! The time is <%= new Java.util.Date ()%>
in the client's browser, access the " IP address of the Http://Linux server/test.jsp" If 7-37 is displayed "hello! The time is current "information, which means that Apache and Tomcat integration succeeded.
