This article mainly talks about "what are the differences between apache and tomcat". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what are the differences between apache and tomcat"?

The difference between Apache and Tomcat:

Apache is only a Web server, can be run as an independent web server, but only support static pages, such as (asp,php,cgi,jsp) and other dynamic pages appear powerless.

Tomcat can also run as a stand-alone web server. But Tomcat is also an application (java) server, it is just a Servlet container.

Because Apache interprets static pages faster and more stably than tomcat, for the above reasons, a real website uses an Apache as a Web server to provide services for static page requests.

And use the Tomcat server as a Servlet/JSP plug-in to display the dynamic pages of the website.

Benefits of Apache+Tomcat integration:

1. Apache is mainly used to parse static text. For example, html,tomcat also has this function, but apache can greatly improve the efficiency. For enterprise applications with a large number of concurrency, it can better display the efficiency of apache.

2. Tomcat is used to parse jsp,servlet, etc. All customer requests will first be sent to Apache. If the request is a static text, it will be parsed by apache, and the result will be returned to the client. If it is a dynamic request, for example, jsp,apache will hand over the parsing work to tomcat and parsed by tomcat (first of all, the two must be integrated in reality). After tomcat parsing is completed, the result will still be returned to the client through apache. In this way, we can achieve division of labor and cooperation, achieve load balancing and improve the performance of the system! And because JSP interprets the code on the server side, integration can reduce the service overhead of Tomcat

Install Apache

Yum-y install httpd httpd-devel

Uninstall the native jdk environment

Rpm-ivh jdk-8u20-linux-x64.rpm installation jdk environment

. / jdk.sh configuration environment variable configuration environment variables

# vi / etc/profile

Append to the profile file

Export JAVA_HOME=/usr/java/jdk1.8.0_20

Export JAVA_BIN=/usr/java/jdk1.8.0_20/bin

Export PATH=$PATH:$JAVA_HOME/bin

Export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

Export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

Source / etc/profile let the / etc/profile file take effect immediately after modification.

Quantity

Java-version to view Java version number

Mkdir / opt/tomcat create tomcat installation directory

Tar-xzvf apache-tomcat-7.0.47.tar.gz decompresses tomcat source code packet

Cp-r apache-tomcat-7.0.47/* / opt/tomcat specifies an installation directory

Cd / opt/tomcat/bin/

. / startup.sh starts the tomcat service

Lsof-iPlux 8080 check to see if it is turned on successfully

Service iptables stop, turn off the firewall

Setenforce 0 shuts down selinux

You can now test whether tomcat has been successfully installed (visit: http://ip:8080)

Install a module that provides a uri path to distinguish the types of client access pages (mod_jk modules are also called connectors)

Tar-xzvf jakarta-tomcat-connectors-1.2.15-src.tar.gz

Cd jakarta-tomcat-connectors-1.2.15-src/jk/native/

Yum-y install gcc gcc-c++- installation and compilation tool

. / configure-- with-apxs=/usr/sbin/apxs

Make

Make install

Check to see if mod_jk.so already exists

[root@wg63 native] # ls / etc/httpd/modules/mod_jk.so

/ etc/httpd/modules/mod_jk.so

Generate a configuration file for mod_jk

Cd / root/Desktop/ jakarta-tomcat-connectors-1.2.15-src/jk/conf

Cp workers.properties / etc/httpd/conf

Edit profile workers.properties

Vim / etc/httpd/conf/workers.properties

You can delete everything in workers.properties and add the following

Worker.list=worker1

Worker.worker1.type=ajp13

Worker.worker1.host=localhost

Worker.worker1.port=8009

Modify Apache configuration file

Vim / etc/httpd/conf/httpd.conf

Add index.jsp to the DirectoryIndex parameter

Add http://www.fuke029.com/ to the last line of the configuration file

LoadModule jk_module modules/mod_jk.so # load mod_jk.so module

JkWorkersFile / etc/httpd/conf/workers.properties # specifies the configuration file for the mod_jk module

JkMount / * .jsp worker1 # forwards all requests ending in .jsp to worker1

Service httpd restart restart Apache

Access http://localhost/index.jsp in the browser, if you can access the index.jsp page, the integration is successful.

At this point, I believe you have a deeper understanding of "what is the difference between apache and tomcat". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
