Apache Tomcat 9.0.8 install check?

0 votes
1,062 views

I am trying to find out through registry checking whether or not Apache Tomcat 9.0.8 is already installed or not. If the below registry is not there, then my program installs Apache Tomcat 9.0.8 installer otherwise it moves on to other installation and completes. It's kind of prerequisite check program.

HKEY_LOCAL_MACHINESOFTWAREApache Software FoundationTomcat9.0Tomcat9

However, everytime program just proceeds to install Tomcat despite it is already installed? Am I checking wrong registry?

That is the correct registry path for installed TC. Additionally you can also try to read value of InstallPath.

Where? Can you be more specific which key are you talking about?
commented Jun 18, 2018 by anonymous
Under same registry entry. Here is the full path for installed Tomcat8 on my laptop:
HKEY_LOCAL_MACHINESOFTWAREApache Software
FoundationTomcat8.0Tomcat8_1InstallPath

There is another key called version - if you want to verify the version again:
HKEY_LOCAL_MACHINESOFTWAREApache Software
FoundationTomcat8.0Tomcat8_1Version

Apache: Subdomain vritual host proxy to Tomcat with ajp

I have a domain domain.com that points to a server. Now I have a subdomain sub.domain.com that points to another server that has Apache running and Tomcat. I want this subdomain to point to a application deployed on the Tomcat instance through ajp.

I have configured the following in httpd.conf: 

   ServerName sub.domain.com 
   ProxyRequests Off
   ProxyPreserveHost On  
   Order deny,allow Allow from all  
   ProxyPass / ajp://localhost:8009/ 
   ProxyPassReverse / ajp://localhost:8009/

and in Tomcats server.xml:

But when I go to sub.domain.com the url changes to otherdomain.com and shows me a php website running in Apache and declared as following in httpd.conf: 

 DocumentRoot /var/www/html/otherdomain.com 
 ServerName otherdomain.com 
 ServerAlias www.otherdomain.com

I only get it to work when I change the port in the sub.domain.com virtual host declaration to for example 8001. Then when I go to sub.domain.com:8001 it shows my tomcat application (ROOT.war) as expected.

So my question is: what could be going wrong that it doesn't work with the default port 80? I can't find any configuration that is causing this, but I'm probably missing something or is my virtual host configuration wrong?

How to calculate Apache Tomcat resource?

We are using Apache Tomcat6 as application server for the website. Two virtual servers are configured for this and each one of the servers had 2 CPUs and 4 GB RAM until 26 JAN 2015 when both Tomcat servers crashed. So we added some resources to the virtual servers (Now it is 8CPUs and 8GB RAM each box) and increased maxThread parameter of tomcat from default (which is 200) to 300 and restarted Tomcat servers. OS of the systems are Linux6.5 .

We need to know what the relationship between thread and memory is. If N numbers of requests coming to the server how many threads can process that and how much memory is required for that. Actually we are targeting to increase the maxThread count upto 500 but we need to calculate that, to process this much of threads what will be the best Hardware configuration?

Please let us know if any more information is required for the same.

How to route the request from apache with custom ports ( 86- http port, 4444-SSL port) to tomcat

We have a set up like Apahce (80,443) redirects the request to Tomcat (8080) using mod_jk.

The new requirement is to route the request from the same apache to another tomcat (8090). Hence I made the different config file for apache with different ports (86,4444) and different worker for mod_jk which routes the request to tomcat.

Now the issue is when I hit the url http://:86 and after providing the credentials, it is redirecting to https://:86 and throwing the below error.

Error in browser:

Secure Connection Failed

An error occurred during a connection to x.x.x.x:86. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long)

Error in logs:

Could you please suggest where it might went wrong and the way forward..
