How to deploy my web-application on Tomcat so that it can be accessed by using IP of the server alone?
Note: I have Tomcat running on port 80.
you need to deploy tour application in the ROOT context (rename your app.war to ROOT.war). Check if there is on webapps directory of tomcat the default ROOT webapp that comes with it.

I have developed a web application. The app is configured to run on tomcat server 8.5 on port 9000. When deploying the project it runs on localhost:9000. But localhost:8080 not working. I have checked the server.xml and it is configured to run on port 8080. The other tomcat 7 runs on localhost:9090.
Earlier I manually stop the server while deploying the project on IntelliJ since the project was configured to run on port 8080 and it shows error "port 8080 already in use."
Why this happening?
Have You tried closing existing running processes? That could explain 8080 already in use.
What happens when You are running tomcat from intellij, then server.xml configuration is not respected as it is overwritten by Intellij's tomcat configuration.
One is able to define his own server.xml or context.xml by specified folder under Tomcat base directory where those files are located. One is able to find Tomcat base directory when clicking Configure close to Application server entry.
I've created another instance of Tomcat(port: 81) to run a different application in a server. Tomcat is running successfully but I want to run apache web server on top of it. So, I copied existing apache in another folder and configured to the another instance of tomcat. I'm facing below error. Your help will be greatly appreciated.

It would appear that both instances are configured to also listen for https connections on the default port (443), i.e. while you may have configured them to listen on different http ports (i.e. 80 and 81), you haven't done the same for https.
First, something else is already using that 443 port, so try 8443.
Also, technically, you can install Tomcat twice using different service names, but why. The beauty of Tomcat is using one installation for multiple applications.
Tomcat is intended to support multiple apps. With a .war file you simply upload your .war file to web apps folder. Tomcat will automatically extract the war file.
To run app as ROOT application, delete the ROOT folder in Tomcat. Rename the .war file for the app you want to install to ROOT.war, it will extract to ROOT folder and you will access it from http://servername:8080, if you kept the default settings of the tomcat connector.
Now, to add a second application, copy a .war file to Tomcat webapps folder, with a different name other than ROOT.war, such as example.war. It will automatically extract the .war file into an example folder. To access that application, go to http://servername:8080/example. You will not have two Tomcat connectors for port 8080, just the 1, and you will access non-ROOT webapps via a context path.
Option 1:
If you want to use TLS in Tomcat, you need to uncomment the 8443 connector in Server.xml. You also need to create a keystore, and put in that keystore information in Server.xml to allow TLS.
Option 2(Doesn’t work with option 1, unless you pick a different port):
If you want a web server with TLS, then set Apache Web Server to listen on 8443, which will also require creating a key store and virtual host file in Apache Tomcat, but leave the Tomcat port at 8080 as it normally would be. Then use virtual host settings on Apache Web Server to proxy to the Tomcat apps (jumping from 8443 to the 8080 ports on the same host with Tomcat only listening on 127.0.0.1 or different hosts with proper network separation so people can’t get around the Web Server). Apache2 would be listening at the Web
Server FQDN.
Example:
Skip the Apache Web Server, and use different context path settings (as needed) for each tomcat application on the single 8443 port. (Make sure Apache2 is no longer using 8443).
ROOT app:
User—>https://servername:8443
App2:
User—>https://servername:8443/app2
Using Apache Web Server, you would proxy from port 8443 to 8080. Apache Web Server listening on 8443, Tomcat listening on 8080. TLS encryption would be at the Web Server. The connection between the Apache2 and Tomcat would be unencrypted on the same server.
This is a pretty thorough example of reverse proxy:

User—>https://servername:8443–>http://localhost:8080
Is it necessary for jenkins, that we need to install apache web server even if we have tomcat installed. ?
From - https://jenkins.io/doc/book/installing/
Jenkins is typically run as a standalone application in its own process with the built-in Java servlet container/application server (Jetty).
Jenkins can also be run as a servlet in different Java servlet containers such as Apache Tomcat or GlassFish.
So you can use Jenkins "as-is" or use with Tomcat.
No. Apache Tomcat can handle HTTP and HTTPS requests on its own as configured in server.xml
Default HTTP Port is 8080 -> default local URL: http://localhost:8080/jenkins
Default HTTPS Port is 8443 -> default local URL: https://localhost:8443/jenkins
We have windows based XAMPP webserver which has built-in tomcat server. I have deployed an app on tomcat and having issue while mapping url to application.
Xampp (80,443) and tomcat (9091,9093) are running on different ports. I have configured server.xml but when I am trying to access mapped url, its not reachable. I checked in network tab on browser inspector it is trying to reach on server's port 80.
Below is configuration part from server.xml
I have Apache tomcat 7 where I build my web application and I also have Apache Web Server where my web site exist wrote on Css and HTML. I want to inject my web app on web site. How can I make my Tomcat as web server and container and transfer web site from Apache WebServer to Tomcat. ???
I know tomcat also can work on 80 port. Just I use to read documentation how to integrate Apache WebServer with Tomcat using mod_jk ajp connectors and etc to do, seems like it doesn't work.
If you want to use Tomcat as your web server (to serve your .html and .css files and probably images), then you can just get rid of the Apache Web Server; you no longer need it, according to your question. Then, after putting all your html/css/etc. under webapps/[app-root]/, make sure that all references to port 8080 in Tomcat's conf/server.xml are changed to port 80, reboot Tomcat, and you'll be good to go.
