Server :: Using Apache As A Front End To A Running Tomcat Instance?
Jul 20, 2010
I am having a problem.I use Ubuntu 10.04 server edition.Two computers on LAN one with Public Ip A other with local (Class C IP)say it BWith a third computer in same subnet I can access a TomCat application running on B as http://Ip of B:8080/applicationI want to use A as a Reverse Proxy for this application to be reachable from internet.So on Googling I came across some thing known as mod_ajp I enabled that on my Server A asa2enmod proxya2enmod proxy_ajpa2enmod headersbut after that I am not able to understand as how do I define vhost to be able to forward HTTP request which come on A as www.myserver.com/appto B which I can see internally as http://Ip of B:8080/application so Tomcat on B handles this.

I have used same Hardware and OS platfrom for web server benchmarking and i have used similar php and jsp scripts for Apache and Tomcat. For this testing i have used apache ab benchmarking toolFrom this statistics i would like to clarify the performances about Apache and Tomcat.
1. why Tomcat have taken too much of time to finish this 10 million requests to compare with Apache?
2. why this huge different for "Request per Second"?
3. To Tomcat i have increased multi thread level 300 and JVM memory usage upto 2048mb(but performances not increased), rather than these, is there any other performance tune-up settings for Tomcat?
4. from these statistics, can i come to the conclusion that apache is the best?
5.do u feel that ab tool favouring to Apache?

I'm configuring a web server using Apache and Tomcat. I use Apache 2 and various instances of Tomcat5 and Tomcat6..I try that Apache serves the static data and tomcat the dynamic (Apache receives all requests, sending tomcat only the dynamic)I see that Apache and Tomcat can be connected using http or ajp Can any tell me:
- What connector should I use: ajp, http,...?
- How can I say Apache to serve the static data and Tomcat the dynamic?Due to I have many instances of Tomcat, connectins http and https, https with client certificates, and due to the port configuration:
- Is there any way to configure Apache-tomcat without the use of ports in tomcat (a differect connector)?

we have configured snv in our server but when we tried to access our svn folder from client its saying path not found error.This is because apache is mapped to tomcat so when we tried to access svn by default it looks to some other path and displaying path not found error.My question is how to restrict apache from forwarding its request to tomcat or else how to stop the tomcat service. I am using centos and i tried with /etc/init.d/tomcat5 stop but it is not getting stopped.

I have installed apache tomcat 5.5.27 in centos5. I edited the server.xml file also. The startup.sh and shutdown.sh commands are working fine. But tomcat is not opening in the browser. Can you suggest me something or tell me the steps involved in installing tomcat. Is admin.tar.gz of apache tomcat required for its working?

Right now I have Apache and Tomcat running on the same server. For reasons I won't go into I'm experimenting with putting Apache on a separate server, and installing Tomcat on multiple back-end servers. This isn't a load-balancing scenario as each Tomcat container on the back-end servers will be providing a separate application/responding to a different url. In a typical setup (everything on one box) the configuration file (we use workers.properties)sets what appears to be parameters such as the location of tomcat and Java. For example, here is the current output of workers.properties:Quote:
workers.tomcat_home=/usr/share/tomcat6/
workers.java_home=/usr/lib/jvm/default-java
ps=/

I've installed Apache Tomcat--6 and even jdk1.6.I've even created a tomcat.sh file to start the serverautomatically and it includes the Environment variables also ($CATALINA_HOME & JAVA_HOME) for automatic startup.Next when i'm using http://localhost:8080 to call the server it shows unable to connect.I've tried changing the port no of tomcat in server.xml file. but still its not working.
-->Then i tried using--telnet localhost comand--it shows Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
Here I'[m stuck i don't understand how do i make the localhost work.
-->If I'm giving telnet localhost 25 the sendmail server is working.But the 80 and 8080 ports are not getting configured.
-->I've tried adding the port and its name in /etc/services file but still its not working.
-->When I'm giving the command--/sbin/chkconfig --list--->Its shows: xinetd based services:
...
...
telnet on.what should i do to get my tomcat server work properly.

I am having two domains. for ex: www.example1.com and www.example2.com. These two domains need to be hosted under one ip. Yes by configuring name based virtual host we can do that. But, my question is my first domain(www.example1.com) need to be hosted by Apache web server, and my second domain(www.example2.com) need to be hosted by Tomact. Is it possible to configure name based virtual host for a scenario like this.

Fedora 14. I have Apache HTTP Server installed and running fine. I am interested in doing some java servlet pages. Am I correct that in addition to the above I need to install another server - for example Tomcat - that knows how to process java servlets? I see that yum has tomcat. And that Tomcat is not an add on to the HTTP Server, but an alternative to it? i.e I start one or the other?

I've got my first EC2/cloud instance of Ubuntu up and running. This is my first time really dealing with the server edition. I've loaded Apache, Tomcat, PostgreSQL, and Webmin. I've got a public IP on the instance and it is working. I've opened, for now, ports 80, 8080, 443, and 10000 to 0.0.0.0/0.
I cannot get into Tomcat Manager or Webmin at all through a browser. For Tomcat, I've restarted, stop/started, and verified that Tomcat is running. I installed Webmin all through apt-get commands so any dependencies should have been installed (first time doing it this way), but cannot get to the login screen. But if I just go to the IP, Apache goes to the "It Works." splash page. Did I miss some set up? Is there an internal firewall in Ubuntu Server edition that needs to be set?

Due to a ton of research I believe I now understand the output of ps, top, and free better than ever, and also have a relatively decent grasp on memory management (virtual address space, etc.) than I ever did before. With that being said, my server is super low on available memory and I can't make 1+1=2 on why it is. I suspect it's Tomcat/JVM (which I admittedly know precious little about). I am rebuilding this server (for a number of reasons) and plan to install 8GB but solving this mystery is key to supporting/promoting my design plans.
Relevant info So, I have very little memory left, I am swapping pretty hardcore, and even though I suspect it's the Tomcat/JVM stuff, it sure doesn't look like it from the memory tools. For that matter though it looks like "nothing" is using memory, or certainly not enough to cause such a low memory problem. The server was rebooted 24 days or so ago because it actually ran out of all virtual memory. How do I solve this mystery? Am I using the wrong tools? Am I misunderstanding my tools? What can I do to track down the processes depleting my memory?

My first time installing centos server and adding it to xp home network. I am new to setting up my own network in general. I have a home windows wired ethernet xp network (simple linxs router) with 2 xp boxes and one centos5 box all connected to the same router. I just set up the centos box running tomcat on port 8080. I need to do two very basic things at this point, but am not sure what I need to do:
What do I need to do so I can:
1. Connect in firefox on one of my xp boxes and call the tomcat server running on my centos box?
2. Be able to ftp to centos box from either of my xp boxes?

Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.

On my crontab there is an entry to run a script I wrote that backs up my local files to my remote server. It was working great, running once a day. However, I now want to make the script run every hour.The problem is that if there are too manyfiles to transfer (Example:I ripped a DVD in the last hour) the actual backup may take longer than 60 minutes.So I want to modify the script to check if my backup script, based on rsync, is running. If rsync is still running then do nothing and exit the script. If it is not running, execute the script as normal.

I am trying to set up an Apache frontend server followed by a Tomcat server. Tomcat needs to run as an https service. I will have two services, both accessible independently, if desired.This login module is a webapp, running inside Tomcat.
Question:
Do I configure the Tomcat on port 8443 (I want to run it as a non-root) and do nothing with Apache or do I run on the standard port 8080 and configure Apache?
If Tomcat, is it server.xml? (connector?)
If Apache, is it httpd.conf?

I want to setup tomcat and apache to run on SSL. I did set up apache to run with ssl and tomcat (wo ssl). Tomcat is on 8081 and apache is on standard HTTP/HTTPS ports. Now I installed JK module and I want to access "host-manager" application on tomcat with ssl, but when I try https://localhost/host-manager/ I get 503 error and when I try [URL]. I get 404 error. Here's my /etc/apache2/sites-available/default conf:
Code:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory> .....
Here is /etc/apache2/mods-enabled/jk.load:
Code:
LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so
JkWorkersFile /etc/apache2/workers.properties
JkLogFile /var/log/apache2/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
and here is workers.properties:
Code:
worker.list=worker1
worker.testWorker.port=8009
worker.testWorker.host=localhost

I have a Apache web server and a separate tomcat 5 server. I can run the jsp-exaples just fine using HTTP. However using HTTPS fails. For some reason it appears HTTPS is not forwarding to the connector, I get 404 not found, returned.If I simply try https://apache_server_ip I successfully connect to the default Apache page.According to this page it should just work. Apache should do the ssl encryption/decryption and tomcat operate as normal.
