I have below shell script to stop/stop the tomcat.

else
echo Tomcat is not running.

then
echo Tomcat seems to be running. Use the restart option.

Now above script works with local tomcat. Now how can i modify above script to stop/start remote tomcat?
Thanks!
You could use ssh to execute a local script on the remote machine to start/stop Tomcat, so if you are in a linux terminal, you could do something like:
ssh username#remoteMachine /home/username/myScipts/start_tomcat.sh
where start_tomcat.sh would be a script in the remote machine, of course you would need a valid username/password on the remote machine, and also the remote machine would need to have sshd installed and running

In jenkins maven project we can use BUILD_ID=DontKillMe to prevent hudson script shutdown the shell calls.
Like: BUILD_ID=DontKillMe java -jar target.jar
But add BUILD_ID is not work in Jenkinsfile.
Jenkinsfile:
#!/usr/bin/env groovy
node {
stage('Build') {
checkout scm
sh '/opt/gradle/gradle-4.1/bin/gradle clean build'
}
stage('Deploy') {
sh 'mkdir -p /opt/www/foobar'
sh 'cp build/libs/*.war /opt/www/foobar/newest.war'
sh 'chmod 755 ./deploy.sh'
sh 'nohup ./deploy.sh &'
sh 'while ! httping -qc1 http://localhost:10000 ; do sleep 1 ; done'
}
}
After hudson script executed, all the shells called by hudson script would be shutdown. Even double nohup still not work.
deploy.sh:
#!/bin/bash
nohup java -jar -Dspring.profiles.active=prod /opt/www/foobar/newest.war /var/log/foobar.log 2>&1 &
You can use BUILD_ID=dontKillMe in sh step the same way
sh 'BUILD_ID=dontKillMe nohup ./deploy.sh &'
I found an another way to execute scripts and cannot be killed.

However, when I start it with command:
service ConfigurationService start
The app start but does not have permissions to connect to DataBase. When I invoke my web API I can see such error:
There was an unexpected error (type=Internal Server Error, status=500).
Could not get JDBC Connection; nested exception is java.sql.SQLException: Access denied for user 'root'#'localhost' (using password: YES)
If I start my application using command it works without issues:
java -jar ConfigurationService.jar &
I understand that it is something related to users and permissions but I am new in Linux configuration. Appreciate any help
after symlink my app to the /etc/init.d/myappname.
/etc/init.d/myappname start gives "Failed to start"
/var/log/appname.log tells
"start-stop-daemon: unrecognized option '--no-close'"
when i remove the --no-close, the jar becomes corrupted and cannot run anymore. i am struck.
bdw my jar is fullyexecutable jar. i.e., when i run the jar alone it starts up the springboot normally.
whats going wrong here?

I assume you already created an executable JAR of your Spring Boot app.
Copy your app to /var/appname/appname.jar
Make sure it's given execute permission:
sudo chmod +x "/var/appname/appname.jar"
Create a config file /var/appname/appname.conf with the following content
USE_START_STOP_DAEMON=false
Follow instructions from Spring Boot Reference Guide
To install a Spring Boot application as an init.d service simply create a symlink:
$ sudo ln -s /var/appname/appname.jar /etc/init.d/appname
Once installed, you can start and stop the service in the usual way. For example, on a Debian based system:
$ service appname start
i finally solve this problem.
--no-close is a parameter that was "recently" added to start-stop-daemon
http://manpages.ubuntu.com/manpages/wily/man8/start-stop-daemon.8.html
I run my app.jar on Ubuntu 12.04 LTS that has
start-stop-daemon 1.16.1.2 for Debian
You could know what version you are running using:
start-stop-daemon --version
on linux console.
I downloaded a newer version of start-stop-daemon on
https://pkgs.org/ubuntu-14.04/ubuntu-main-amd64/dpkg_1.17.5ubuntu5_amd64.deb.html
Install the deb package and spring boot jar will finally run.
Run "service myappname start" as mentioned in the document http://docs.spring.io/spring-boot/docs/current/reference/html/deployment-install.html
There is a difference between /etc/init.d/myappname start and server myappname start
So I had a tomcat 7.026 smoothly running on a CentOS 6.7 Server on its default port 8080.
Recently it stopped running on its own.

I finally resolved the issue.
After running
java -version
It seemed that the Java Installation was somehow corrupted so all I had to do was to uninstall and re-install Java and that made the trick for me.
I have a Java application running on JBoss EAP 6 which I can "hit" from mobile app on chrome using urls like: 127.0.0.1:8280/myAwesomeJavaApp/coolService ... so when I package the app I am using urls like this
192.168.1.64:8280/myAwesomeJavaApp/coolService //this is not working
192.168.1.64 // this gets me to my localhost
(connected to WiFi (testing purposes))
I can access all other Apache web apps in my localhost , but can't consume JBoss EAP 6 services.
What am I missing ?
