I am playing around GeoServer and I have a Apache HTTP Server
I want to put GeoServer on my Apache HTTP Server, but we can only download a WAR file of GeoServer for Tomcat.
Is it possible to install Tomcat on Apache HTTP server?
Tomcat is seperate product which has nothing to do with the Apache Web Server and has to be installed separately,
Apache Tomcat has nothing to do with Apache HTTP Server. If you are trying to deploy some java webapps with JSPs and Servlets (and may be other web framework that uses these two) you just need to install tomcat server only. You can download it from here.
If you want to know the difference b/w Tomcat and HTTP server its given in this question
Hope this is useful. If any mistakes pardon me.

I have apache2.4 webserver installed on ubuntu 14.04, which has all the configuration for the virtual host file.Also I have configured ssl certificates in it. But I want to run this apache server behind other proxy server which have different IP then the Web Server.
Please suggest me the best way to do this.I am planing to install another apache on the proxy server and achieve this using reverse-proxy.But Please suggest any better way to do this.
Thanks
Vinay
I recently read some doc about setting up a reverse proxy server and it seems that ningx is a better choice than Apache for this task: it is very lightweight and really easy to configure. For example in a doc I read the writer could not manage to set up correct proxy for HTTPS for Apache, while another one trying the same configuration for nginx set it up easily. I am an old Apache fan, but if I had to install a proxy, I would chose nginx.
Can you have two separate apache servers running on the same system in parallel, as long as they make use of different ports?
I have a system I need to install JIRA on, but the system is already in-use and running an Apache server for a separate project. The JIRA installer comes with a pre-configured apache tomcat server. If I just installed JIRA, would I run into a problem from the pre-existing apache server?
If you’re asking about running two Apache Tomcat instances, then this is not a problem. Moreover you can share the same CATALINA_HOME between many separate instances of Tomcat, each with own CATALINA_BASE. I’m often running separate Tomcat instance per application on production servers. See this init script for a hint about parameters.
But if you’re asking about running Apache HTTP Server and Apache Tomcat on the same server, then it’s a little bit trickier. Commonly used approach is to use a web server (Apache HTTP, nginx, …) as a reverse proxy in front of Tomcat. Then many applications can run under the same port and IP address. In case of Apache HTTP Server, see mod_proxy_ajp.
Apache HTTPD and Tomcat are 2 different servers. Also, JIRA doesn't run on port 80 so in this case there will not be a conflict for port numbers. If you want to expose your JIRA on port 80, you can use mod_proxy for the Apache HTTPD to relay the requests to the actual port JIRA is running on, so that it is transparent to the user.
So basically: Yes, you can run both Apache HTTPD and Apache Tomcat on the same machine if not using the same port.
I want to add a javascript based chat system to my web app. I have read in many places that apache needs to forward(proxy) the requests to the xmpp chat server.
From what I have understood , I either need to add proxying support to apache server
OR use the jabberHTTPbind servelet.
I am trying the first thing. Add proxy support to apache. Now within Eclipse I am using Tomcat 7.0. I think this Tomcat comes with its own web server and is not using Apache. Is that true ?I am using Tomcat from http://tomcat.apache.org/download-70.cgi and added server in Eclipse by providing its extracted path.
I am not able to find any apache related folder structure eg(/etc/apache2/apache2.conf) within my Tomcat extracted directory.Also can't find httpd.conf anywhere .
Should I need to download apache separately and connect my tomcat to it.
I think adding proxy support to apache is required because javascript code won't be able to connect to any URL other than the current domain. so the question again is the same , where are all these apache2.conf and httpd.conf to add mod_proxy. and where can I do the virtual host mapping.
Any help to move ahead with be very much appreciated.
You need to install the Apache HTTPD server and enable reverse proxying. Read the doc on mod_proxy on how to do this. There are tons of resources on Stackoverflow as well; search for Apache reverse Proxy. The conf files you mention are part of the Apache HTTPD install.
javascript code won't be able to connect to any URL other than the current domain
That is generally true unless you enable CORS
Please help! I got very frustrated with this assignment to demonstrate Apache and Java Struts. I cannot make struts apps run in the Apache web directory. They only work under Tomcat.
Can I use Struts only under Apache without Tomcat? ... Thanks very much!
Apache and Tomcat serve different purposes. You cannot use Apache to run Struts because it's just a web server, not a java web container.
What you could do is to setup Apache as a reverse proxy to a tomcat instance, so the "Internet" would talk to your Apache, but still Tomcat would be serving your requests in the end.
Recently our Software Analytic provider (NETTRACKER) sent us a plugin in order to be able to capture visitors in a better way. This plugin is for Apache 1.x and Apache 2.x. They said and I quote
that since Apache Tomcat is built on Apache HTTP server the configuration of the plugin should be the same.
I have looked for a httpd.conf in our tomcat deployment but we cannot find one, the only configuration that is similar to that one is the server.xml under the /conf directory.
If someone has better information regarding these two incredible products (Apache HTTP server and Apache Tomcat) I will greatly appreciate to draw the differences.
EDIT:
In case you are curious we know that Apache Web Server and Tomcat can work together using the mod_jk option and other proxys. But this will be too complex for our deployment.
Apache Tomcat and Apache HTTP are completely different server technologies. It is impossible to use a plugin for Apache HTTP server with Tomcat.
Apache HTTP server is developed in C and so are the plug-ins. On the contrary Tomcat is now completely developed in Java. Tomcat doesn't only serve static content, but it can also serve JSP pages and servlets.
Tomcat is used for hosting Java Web Applications. It can sure serve static content - you can host a web application using only Tomcat. Secure connections are supported and the performance is also very good (comparable with the performance of HTTP server).
A plain installation of Apache serves static content. Using the appropriate plug-ins, HTTP requests can be redirected to an application server (Tomcat, JBoss, Glassfish) or a script language interpreter (PHP). With this way dynamic content can be generated. The big advantages of Apache are the numerous plug-ins available, which allows administrators to configure and monitor web sites any way they want and that is the most widespread server available. This makes it the most secure solution, since it is thoroughly tested and any discovered flaw is corrected very quickly.
The best solution would be to use Tomcat proxied by an Apache server. It isn't so difficult to set up. If you can't do this, then you can't take advantage of Apache's plug-ins.
You see this confusion all the time. Many people think that Apache is a web server where in reality it is the name of an organization that has a web server project called "The Apache HTTP Server Project". In short the web server is called HTTPD (D as in daemon or Unix process).
Tomcat is another Apache project. This project implements a Java servlet engine to serve JSP pages and servlets. Tomcat and HTTPD have nothing to do with each other. However, you can set up HTTPD and Tomcat so that they work together. This way you can have HTTPD serve all static content, do URL rewriting and much more fancy stuff that the built in Tomcat web server can't do (or can't do very well). Whenever a JSP page is requested, HTTPD will pass the request on to Tomcat. Tomcat will process the request and will hand the output back to HTTPD which in turn will send it to the client.
Apache has many interesting projects. E.g. there is also a project called Geronimo which is a Java Enterprise server (J2EE). You can e.g. choose to embed Tomcat inside Geronimo to handle requests for JSP's and servlets where Geronimo does the more enterprisy stuff (LDAP, Messaging etc.). And you guessed it probably already, you can use HTTPD as a static content server for Geronimo as well.
totally bogus. Apache httpd plugins are written in C, Tomcat is pure Java.
Tomcat is a Java servlet engine. It can be hosted under Apache or IIS or quite a number of other external facing web servers. It sounds like you may be currently running your Tomcat instance standalone...
If you serve the JSP/servlets off of port 8080 and have it do things standalone, on the same host machine that Apache is running on, this can allow you to have them loosely coupled. Having multiple web servers fielding independent requests is not recommended, especially if you want to use server-based authentication along with Apache. Typically, you have one outside facing server that shepherds everything through it... Apache does this quite well, and the plugin you mention probably relies on this type of setup (everything gets wired through Apache) for its features/capabilities, based on your brief description of it.
If you would like to serve up your Tomcat servlets under Apache, you could configure apache to forward a class of URIs to your tomcat server instances. you could achieve this type of forwarding through mod_rewrite. this is a slower option performance-wise, as it adds slight overhead on everything you server up. You could also proxy incoming requests via a CGI mechanism similarly, from Apache to Tomcat.
mod_jk will simplify deployment and increase performance for placing Tomcat into an Apache server config. It is pretty painless to configure if you follow the docs, so I am not sure what you mean by "too complex" for your deployment -- if you want Apache and have Tomcat already, it would seem only a matter of slight config changes to get mod_jk downloaded and installed.
