I am trying to deploy an application WAR file using Jenkins ANT to build the WAR and restart the server.
Once the WAR is built, I have written a shell script to stop the application server, deploy the WAR file and then restart the application server.
#Shutdown Tomcat
ssh tomcat#<servername> "cd /home/tomcat/app/bin/;exec bash ./shutdown.sh"
#waiting period
ssh tomcat#<servername> "sleep 10"
ssh tomcat#<servername> "cd /home/tomcat/app/webapps/;rm -r *"
#Copy the WAR file to webapps
#Start the tomcat server
ssh tomcat#<servername> "cd /home/tomcat/app/bin/;exec bash ./startup.sh"
It does shutdown the server, clear some temporary files but fails to start the tomcat server. Any idea why this would be happening?
I have tried to see if there are other processes or ports still in use guessing maybe the shutdown was not clean. However there doesnt seem to be any issue like that. When I manually start the tomcat server for the application by going to the tomcat/bin directory, Tomcat starts without any issues.
Thanks in advance.
I have the tomcat up and running on remote machine.
Now i need to create a batch file to restart the tomcat. I am using windows.
Stop tomcat
start tomcat
How can i write a batch file to restart it?
Thanks!
There are scripts in the bin directory of tomcat that will start and stop it called starup.bat and shutdown.bat IIRC. You will have to ssh in to remotely run them.
Also, if you're running as a Windows Service, there are ways to remote manage those service, but my Windows is rusty. You'll need to google for that.
You'll need to write a batch file either to SSH in or to restart the service.
I am a newbie in Java, and I am trying to develop a web application.
I have Windows 7 32 bit. I have installed Java 7 and set the path and classpath as well. After that I installed Tomcat 7.
When I try to open tomcat home page using URL localhost:8080, it does not open and Tomcat stops automatically.
Please help me.
Make sure no other application using port 8080 before starting tomcat. If that's not the problem please paste tomcat log.
If you want to change tomcat's default port, go to tomcat folder and open conf folder, in which you can see server.xml. In that file you can see something like <Connector port= . Change the port value and start tomcat.
If you started tomcat through eclipse, It can be solved in different ways too.
Method 1:
Right click on server --> Properties
click on Switch location and apply.
Method2:
Double click in the server in eclipse.
Change Server location to Use tomcat installation(takes control of tomcat installation).
Your issue is not with port 8080, but with port 8005. Port 8005 is the shutdown port for Tomcat.
Rather than trying to figure out what is using port 8005, it may just be easier to edit TOMCAT_DIR/conf/server.xml and change the shutdown port to 8006
<Server port="8006" shutdown="SHUTDOWN">
For *Unix based systems, you can check the ports used by a particular application by issueing the following command in the terminal
[~/.]$ netstat -tuplen
You will get the list of all the ports that are being currently held and used by their respective process ID's
For windows user, type netstat -anin command prompt to see ports that are listening, this may come handy.
1) Using Terminal (On Linux), go to the apache-tomcat-directory/bin folder.
2) Type ./catalina.sh start
3) To stop Tomcat, type ./catalina.sh stop from the bin folder. For some reason ./startup.sh doesn't work sometimes.
For mac users
First Try : go to activity monitor -> search for java and kill the instance then restart the server and try.
Second Try:
Check log file for any errors under tomcat logs folder.
Use below command to check tomcat logs in terminal
tail -f {tomcatpath}/logs/catalina.out
Third Try:
Check if node or other apps using the same port. Use below command to check which app listening to a specific port. You will see list of apps with pid in second column.
lsof -i :8080 | grep LISTEN
Kill the process using below command
sudo kill -9 pid
If you are using eclipse to start the server then check for the server location being used and the deployment path:
In my case changing this to Tomcat installation instead of workspace metadata worked for me.
My issue has solved.I was getting log as below.
SEVERE: StandardServer.await: create[localhost:8005]:
java.net.BindException: Cannot assign requested address: JVM_Bind
My tomcat server was automatically stopping when I tried to open tomcat homepage with
URL.
So I just made some changes in windows->System32->drivers->etc->host file.
keep only 127.0.0.1 localhost and remove all other. your problem will be solved.
Thank you guys for your help :D
If you have your tomcat started (in linux check with ps -ef | grep java) and you see it opened the port 8080 or the one you configured in server.xml (check with netstat --tcp -na | grep <port number>) but you still cannot access it in your browser check the following:
It may start but with a delay of 3-5 minutes. Check the logs/catalina.out. You should see something like this when the server started completely.
INFO [main] org.apache.catalina.startup.Catalina.start Server startup in 38442 msIf you don't have this INFO line your server startup is not complete yet. The problem may occur due to the SecureRandom class responsible to provide random Session IDs and which can cause big delays during startup.
Check more details and the solution here.
Check your firewall (on linux iptables -L -n): You can try to reset your firewall completely iptables -F if you are not into an exposed environment. However, pay attention, that leaves you without protection therefore it can be dangerous.
Check your selinux (if you are on linux).
These are some of the most forgotten and not obvious issues in having your Apache Tomcat up and running.
I am using Eclipse Java EE IDE for Web Developers. Version: Oxygen.1a Release (4.7.1a) in Windows 8.1 x64 with Apache Tomcat 8.5.24 (for testing purpose).
Port Name & Numbers for my Tomcat Server are :
Tomcat admin port : 8005
HTTP/1.1 : 8081 (my Tomcat Listening Port Number)
AJP/1.3 : 8009
Peoples, for those the Tomcat were running good earlier, and sometimes sudden after stopping tomcat server explicitly by pressing the below shown image button or may be other reasons.
Either they continuously failed to start/restart the tomcat with below said error:
Server Tomcat vX.Y Server at localhost failed to start.
or sometimes the Tomcat Server is started but instead of showing Tomcat Homepage in web browser, it is throwing client exception HTTP Status 404 – Not Found. in preferred web browser.
possibly, there are many reasons i.e. wrong Host name defined, Wrong Tomcat Server Locations defined in eclipse, project JDK/JRE version mismatch with Tomcat JRE dependent version, maven project version mismatch due to maven.compiler.source and maven.compiler.target version not defined under properties tag, mismatch version of project facet Dynamic Web Module to 2.5/3.0, Sometimes Tomcat Server is running on Windows Services level, previous stopped Tomcat port number were still listening and the processing pid were not killed in Tomcat defined timespan Timeouts Stop (in seconds): 15(by default) in eclipse and pid still running, failed to start in defined Start (in seconds): XX, etc.
Here I will give the resolution on, how to check and kill the running existing Tomcat port number's processing pid(beware, you must be aware with after effects).
In Windows, open you command prompt, and follow steps(my tomcat HTTP port is 8081):
netstat -ano | findstr :8081
TCP 0.0.0.0:8081 0.0.0.0:0 LISTENING 2284
TCP [::]:8081 [::]:0 LISTENING 2284
if any listening is being there, above command will list details of port listening along with processing pid at last of the line(here pid is 2284).
now kill the running pid like:
taskkill /PID 2284 /F
SUCCESS: The process with PID 2284 has been terminated.
also illustrated the above two steps like following:
Now, after resolving above illustrated reason, start the Tomcat Server.
I had the same issue. My tomcat was started but I was getting HTTP 404 page not found.However, in my situation, I installed tree instances of tomcat. Each instance contains conf, temp, work, webapps and logs folders. Unless I forgot, to copy the global web.xml under conf folder of each tomcat.
e.g: /opt/tomcat/mytomcatInstance/conf/web.xml
The web.xml Deployment Descriptor file describes how to deploy a web application in a servlet container.
So even if my tomcat was up, my web apps could not be deployed properly.
The problems may happen because of memory issue.
java.lang.OutOfMemoryError: Java heap space
please verify the logfile, any issues related to hardware(memory).
Look in TomcatDirectory/logs/catalina.out for the logs. If the logs are too long, delete the catalina.out file and rerun the app.
In my case, the port that tomcat was running on was defined in an application.properties file for 8000, not 8080. In my case, it looked like the same problem described here. Just leaving this here in case anyone has a similar setup and issue! :)
I am using Windows 7 OS.
I just installed jaspersoft server which installed Apache Tomcat and mysql as a bundle along with it.
I go to http://localhost:8080 and theres a message that says webpage is not available.
I am a beginner, and I would like to know if Tomcat is first installed on my computer. Can you tell
me how I can do that ? ( I would also like to know if it has to be started and on what
port it was installed.)
UPDATE
Heres something I did . i am really confused now . I found the location of the tomcat server. I found the server.xml file. The port in the server.xml file was listed as 8005. I also found start.bat which I ran. I now see that http://localhost:8080 works but http://localhost:8005 doesnt . Would you know why ?? The port 8005 should work because thats what was listed in the server.xml
The port 8005 is used as service port. You can send a shutdown command (a configurable password) to that port. It will not "speak" HTTP, so you cannot use your browser to connect.
The default port for delivering web-content is 8080.
But there may be other applications listen to that port. So your tomcat may not start, if the port is not available.
You asked "How do you know, if tomcat server is installed on your PC?". The answer to that question is: You can't
You can't determine, if it is installed, because it may be only extracted from a ZIP archive or packaged within another application (Like JBoss AS (I think)).
You can check in windows services if tomcat is installed it will be listed in windows services.
To check the windows service list of services installed on windows machine use
WINDOWS KEY + R and type services.msc
There you can find all the services related with Jasperreport server like Tomcat and MySQL with name starting Jasperreport server Tomcat and MySQL only if these services are installed and its need to be started by selecting the option.Then you can access it through browser using this link :-
http://localhost:8080
default port for tomcat is 8080.
In order to make
http://localhost:8080
work, tomcat has to be started first. You can check server.xml file in conf folder for the port information. You can search if tomcat is installed on your machine. Just go to start and then type tomcat. If it is installed it will give you the directory where it is installed. Then you can select that path and run it from command prompt. Example if tomcat is installed in C:\Programfile\tomcat. You need to set this path in command prompt,go to bin folder and startup. Example: C:\Programfile\tomcat\bin\startup. Else you can also run it by directly going to the path and run startup batch file.
In case of Windows(in my case XP):-
Check the directory where tomcat is installed.
Open the directory called \conf in it.
Then search file server.xml
Open that file and check what is the connector port for HTTP,whre you will found something like 8009,8080 etc.
Suppose it found 8009,use that port as "/localhost:8009/" in your web-browser with HTTP protocol.
Hope this will work !
For linux ubuntu 18.04:
Go to terminal and command:$ sudo systemctl status tomcat
Open your windows search bar, and search for the keyword Tomcat. If a shortcut file is found instead, you can open the source file location of the shortcut by right-clicking the shortcut file and selecting the Properties.
The purpose is to:
connect to a remote server maybe via host: ip , port: 8181
stop Tomcat that's running on that server
deploy a .war file
restart Tomcat
Underneath are few approaches I have taken so far to achieve this task:
Approaches taken so far:
I have looked at the following solutions but none of them worked for me:
http://www.linuxquestions.org/questions/linux-newbie-8/start-tomcat-server-remotely-824472/ --Not efficient
http://tomcat.apache.org/tomcat-6.0-doc/manager-howto.html#Start_an_Existing_Application
http://raibledesigns.com/wiki/Wiki.jsp?page=TomcatAntTasks
--only start/stop application not the actual tomcat itself
http://cargo.codehaus.org/Remote+Container
-- Which does't start/stop tomcat that's running on that server
If you have ssh access to the server, then you might like to consider the JSch library which you can use in combination with SSHExec Ant Task to start and stop your server:
<sshexec host="somehost"
username="dude"
password="yo"
command="/etc/init.d/tomcat restart"/>
For start/stop tomcat
In linux environment
use SSH to reach the terminal of the remote machine.
from the terminal You can start/stop the tomcat
to start startup.sh
to stop shutdown.sh
Under windows environment
Install OpenSSHD for Windows - this will allow remote "console" sessions.
If you looking for something very "unix-like" then you can install cygwin.
http://www.worldgoneweb.com/2011/installing-openssh-on-windows-7/
to start startup.bat
to stop shutdown.bat
For deployment
Simply go to tomcat manager link on the below page(on any environment)
http://your_server_ip:port_number/
