So I'm trying out JSP for the first time. I found a tutorial that details the installation of the tomcat server and the mod_jk Apache module, but it's a bit outdated. Right now, I've got everything installed and the mod_jk.so file in the modules folder, along with the corresponding loadModule line in the httpd.conf file. The tutorial tells me to copy a file called 'workers.propperties' to the apache conf directory and do some changes inside it, but there's no such file in the win32 binary installation. However, there is a file in the zipped source code, but I'm not sure if I should use it.
I have installed JDK1.6.0U17/JRE6.0/Apache HTTPServer2.2.13/Tomcat6.0.20/Mod_JK1.2.28/Vista
First this question: do you actually need Apache HTTP Server for other purposes? If not, just leave it aside and run Tomcat standlone. I've namely seen too often that starters are somehow under the impression that they need both Apache HTTP Server and Apache Tomcat to be able to run JSP's. This is untrue. Just Tomcat is enough. It's a webserver and servlet container in one.

I have installed Apache Http Server 2.2. I know it is old but need to do some analysis.
I can see there is configuration file name as httpd.conf (found at location InstallDIR\Apache Software Foundation\Apache2.2\conf).
Some places i found they have maintain ssl configuration separate file name as ssl.conf and other configuration in separate file name as local.conf file.
But i can see no such files are present on my conf folder.
Can you please help me here how I can do separation ?
Note: Apache Http Server installed on Windows machine.
Thanks in Advance.
I am trying to set up Apache http 2.2, with mod_jk module.
The intention is to set up a load balancer right on my PC, for test purposes.
So I made some changes to httpd.conf to set some parameters, then I run it and I get the popup:
"Windows couldn't start Apache 2.2 on local PC. For more information check system events log. If it's not a windows service contact service provider and reference the code:1"
I check on the log and I get:
httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.0.35 for ServerName
So I uncomment on httpd.conf line: ServerName myPcName:80 and run it again.
I get the same popup, but this time I don't get anything on the events log.
Any idea on how to let it work?
(Nothing is bound on 80 port.)
Thank you
Please check if port 80 is being used by other application or not. Most of the time in my case "Skype" was using port 80. So I had to stop it and then I used to start Apache service.
To troubleshoot further what you can do is, goto apache's bin directory and run httpd.exe -t option. This will show you exactly what is causing problem.
The configuration file in the apache /conf folder, has a piece of code that starts from C:. It is copyrighted and therefore you cannot change the code.
All you have to do is make a second copy of the whole apache folder and put it directly in your C: directory. Your apache file is in System 32 causing you to use cprompt right. Having 2 identical apache folders one in C: and one in System 32 bypasses the problem.
I'm running tomcat and I want to change the default webroot so that it points to another location. Is there a way to find out what's running tomcat or where the default webroot is set as I can't find httpd.conf which is where I believe it's usually set?
Cheers,
Alexei Blue.
**UPDATE:**
It's been a long time since I looked at this question that I forgot about it. In the end it turned out that we were using Apache HTTPD to accept requests from port 80. From there we had the webroot and ProxyPass rules set in the /etc/httpd/conf/virtual-hosts/default.conf file (these can also be set in /etc/httpd/conf/httpd.conf). From there we had several tomcat instances running, all hosted on different ports which are setup in apache-tomcat-x/conf/server.xml.
When I wrote this question I was trying to setup a new tomcat instance to run an application in development and was told I would need to change the webroot to access my application, which was incorrect. Instead what I needed was to include a ProxyPass rule so that when my application name was recognised in the URL, HTTPD would send the request to the correct tomcat instance to be processed.
E.g.
www.domain.com/myApplication
In /etc/httpd/conf/virtual-hosts/default.conf
ProxyPass /myApplication/ ajp://127.0.0.1:<ajp_port>/myApplication/
ProxyPassReverse /myApplication/ ajp://127.0.0.1:<ajp_port>/myApplication/
Where the ajp_port is setup in apache-tomcat-x/conf/server.xml. I needed to ensure that non of the ports conflicted with other tomcat instances so remember to check all ports i.e. Shutdown, HTTP, HTTP with SSL, AJP etc.
Tomcat doesn't use httpd.conf, that is an apache file. The location of the individual webapps are kept in their individual web.xml files, but the location of all the configs are in ../tomcat6/conf/server.xml and web.xml
Is it where the files come from you want to move, or where it compiles and executes them from?
As #Woody says, Tomcat does not use httpd.conf files: that's an Apache httpd thing (httpd is a web server, Tomcat is a Java application server).
You didn't mention what OS you are using or what package management software you are using (e.g. yum, apt, etc.) so I'll give you generic information as if you had downloaded and installed Tomcat directly from apache.org (which I usually recommend people do for a number of reasons).
Tomcat keeps its server-wide configuration in the conf/server.xml file in the Tomcat base installation directory (often called $CATALINA_BASE for convenience): here, you configure things like what types of connectors (e.g. HTTP, HTTPS, AJP, etc.) to use and which ports they should listen to, clustering configuration, session persistence, global JNDI and realm resources. There are also conf/web.xml and conf/context.xml files that define defaults for all webapps deployed on that instance of Tomcat, but it's best to leave those files alone unless you have a really good reason to modify them.
When you want to deploy a webapp (under the default configuration), all you need to do is drop a .WAR file into the $CATALINA_BASE/webapps/ directory and the webapp will be deployed into a "context path" (aka URL prefix) that matches the name of the file minus the ".WAR" suffix. So, if you have a WAR file called mygreatwebapp.war, then it will be deployed such that your clients can reach it at http://yourhost/mygreatwebapp/. There is a special name you can give a WAR file so that it has an empty context path: if you name your WAR file ROOT.war (case matters), then your webapp can be reached at http://yourhost/. (If you would rather use exploded-WAR directories instead of WAR files, everything above still applies except the directories simply don't have the .war extension).
Given your original question, it sounds like all you want to do is drop a ROOT.war file into $CATALINA_BASE/webapps (or replace the one that is already there): this will deploy whatever webapp you want into the URL space that you might call the "default webroot".
Update
If you want to change the directory where all the webapps live for a host, you can modify $CATALINA_BASE/conf/server.xml and change the <Host>'s appBase attribute to point to, say, /cfusion/main/www/. That will deploy all the WAR files and directories in /cfusion/main/www/ as separate webapps.
If you just want to serve a single webapp from an arbitrary location, you may create a deployment file under $CATALINA_BASE/conf/[EngineName]/[HostName]/[appname].xml. This is a standard file like META-INF/context.xml and contains a <Context> element except that you will have to specify a docBase which points to your webapp (e.g. /cfusion/main/www/mywebapp).
I have my app that serves on localhost:8080. I want to configure things so that it just servers on localhost:80 (or localhost without the port specified). I was told to follow these instructions.
My apache-tomcat that I downloaded is located at /home/myusername/tools/appname/apache-tomcat-6.0.33
I can't find an httpd.conf file in that dir... so I can't make the changes that the above article mentions. I am not sure what to do. I am new to apache/tomcat. Any help would be great!
Those instructions are for apache, which is different from apache's tomcat. What you have (the 6.0.33 thing) is apache's tomcat, which hosts/runs webapps but isn't typically used as a general webserver. You need to download and install apache, then you'll be able to follow those instructions.
You can download the apache webserver here: http://httpd.apache.org/download.cgi
Or if you are using an OS with a package manager, use your OS'es package manager instead.
Typically, the httpd.conf file should be at /etc/apache2/httpd.conf (or /etc/apache/httpd.conf).
New to Apache, and suffering...
Seems to be true:
the default configuration is in Apache directory Apache2.2/conf/httpd.conf
Unsure of that:
it can be elsewhere
to create some separation between test/production, it seems that the best option is
to store all test files, including configuration and logs, in the same directory, with subdirectories conf, log, htdocs, and all production files in another directory using a similar structure.
if my upper directory is d:mywww, then the server needs to be started with the associated configuration file, e.g. httpd -f "d:mywww/conf/httpd.conf"
What will happen to the default configuration file if the -f option is used. Will it be ignored?
If instead of the -f option, you use httpd -d "d:mywww/htdocs" to indicate the directory to serve, but not any configuration file, will the default config file be used and the one under d:mywww/conf ignored?
Can someone confirm or deny?
Is there a well known site with a good introduction on setting up Apache, if possible on Windows. I found the Apache documentation a little bit difficult, and Apache Definitive Guide not clear about this kind of questions.
I was new to Apache 2 months ago, and still suffering. Since you got no replies from pros yet, I'll chip in my 2 cents: (all for Ubuntu 10.10)
httpd.conf is used for your personal configurations, so I'd say that it is not the default configuration file as you specify. The default would be, in my case at least, in /etc/apache2/apache2.conf
you can have a bunch of other conf files. In my case, I can place any file with an extension .conf inside /etc/apache2/conf.d/ and it will be picked up by Apache on restart.
Don't know about the rest. Hope it helps you
