I have to uninstall tomcat before reinstall it.But, I mistakenly deleted the file folder first and then uninstalled it from "control Panel", during this process I think somewhat might be got wrong. Now when I am trying to install it it is giving me the message:-
How can I overcome this?
it means that you have already installed a version of tomcat8 on your pc. But you can fix this problem by opening the cmd in administrator mode. then you start the command:
sc.exe delete tomcat8
That is because the server is not fully out of your computer, here follow these steps to remove the existing server on windows:
Navigate to Control Panel.
Open Administrative tools.
Open SERVICES.
You will find Apache tomcat version name, right click on it and open properties.
Cope the name of the server: Tomcat8/Tomcat9.
Now open and run the command prompt as an administrator:

Write the command: sc Delete Tomcat8/Tomcat9 and hit enter, the existing server is
removed and you are all set to install a new one.
I uninstalled rabbitMq using this guide: https://support.bioconnect.com/hc/en-us/articles/115011178868-How-to-Uninstall-RabbitMQ
uninstalled RabbitMq and Erlang
ended empd.exe in task manager
deleted the directories for rabbitMQ and erlang
deleted HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Ericsson from 'regedit'
removed the service from services
I also deleted the C:\Windows.erlang.cookie and C:\Users[username]/.erlang.cookie.
After I tried reinstalling using this other guide: https://cmatskas.com/getting-started-with-rabbitmq-on-windows/
installed Erlang
downloaded and installed rabbitMQ
Navigate to the sbin directory of the RabbitMQ Server installation directory. 'C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.3.4\sbin'
and ran 'rabbitmq-plugins.bat enable rabbitmq_management'
I navigated to http://localhost:15672/ and the site was unreachable. I opened up services to make sure that the rabbitMq service was on and it was not even created. I tried running the command 'rabbitmq-service install' as admin and got the following back
RabbitMQ service is already present - only updating service parameters
C:\Program Files\erl9.2\erts-9.2\bin\erlsrv: Warning, could not set correct interactive mode. RabbitMQ
Error: The handle is invalid.
C:\Program Files\erl9.2\erts-9.2\bin\erlsrv: Warning, could not set correct service description (comment) RabbitMQError: The handle is invalid.
I am wondering if i missed a step somewhere. Cant get rabbit to work.
I also ran into this problem recently.
These simple steps solved the issue for me:
Open Regedit.exe
Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Ericsson\Erlang\ErlSrv\1.1\RabbitMQ
Remove that key
Now running rabbitmq-service.bat install is successful.
Try to remove the service and reinstall it using the following steps:
Open CMD as administrator and navigate to the sbin folder (Mine is C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin)
Remove RabbitMQ service by:
rabbitmq-service.bat remove
Reinstall it by:
rabbitmq-service.bat install
Start the service by:
rabbimq-service.bat start
I have the following issue. I deleted the guest user and now basically I cant login to rabbitmq using guest-guest.
I have tried the following things:
1) I did uninstall the service and install it again. It didn't work. It worked for some other colleagues but it didn't work for me. I have tried to uninstall/install nearly 10 times. I can see the service disappearing and readded. Still no success
2) Config file. The config file resides in the following location :
C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.5.1\etc\rabbitmq.
I removed the comments from the following setting :
It was like that
%% {loopback_users, []},
and now it is
{loopback_users, []},
still no success. I restart the service every time i modify the config file but still no success. It was working before I delete the guest user. Does anyone know what else could I do or what am i doing wrong??
Thanks!!
Try again but with the config file found in:
C:\Users\<<Username>>\AppData\Roaming\RabbitMQ
For environment changes to take effect on Windows, the service must be re-installed. It is not sufficient to restart the service.
You can re-install from Start Menu > RabbitMQ Server > RabbitMQ Service - re(install)
On a Windows 7 Enterprise machine, I made a fresh install of Erlang 17.4 and RabbitMQ 3.4.3 x64. The installation was successful and uneventful.
I have not yet tried to create my first queue or exchange, but I already see trouble. This problem is similar to another SO post, but that other post appears to involve clustering, which I don't have. Furthermore, that other poster can circumvent his issue by restarting the RabbitMQ service; that approach does not work for me.
My "nodedown" problem is evident at the RabbitMQ command prompt:
C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.4.3\sbin>rabbitmqctl status
Status of node rabbit#TPAJ05421843 ...
Error: unable to connect to node rabbit#TPAJ05421843: nodedown

rabbit#TPAJ05421843:
* connected to epmd (port 4369) on TPAJ05421843
* epmd reports: node 'rabbit' not running at all
other nodes on TPAJ05421843: ['RabbitMQ']

current node details:
- node name: 'rabbitmqctl-19884#TPAJ05421843'
- home dir: H:\
- cookie hash: PD4QQCYrf0TME9vIko3Xuw==
Based on the above, I chose to check the status of the node explicitly named 'RabbitMQ'. I get this:
C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.4.3\sbin>rabbitmqctl -n RabbitMQ status
Status of node 'RabbitMQ#TPAJ05421843' ...
Error: unable to connect to node 'RabbitMQ#TPAJ05421843': nodedown

RabbitMQ#TPAJ05421843:
* connected to epmd (port 4369) on TPAJ05421843
* epmd reports node 'RabbitMQ' running on port 59301
* TCP connection succeeded but Erlang distribution failed
* suggestion: hostname mismatch?
* suggestion: is the cookie set correctly?
current node details:
- node name: 'rabbitmqctl-23076#TPAJ05421843'
- home dir: H:\
- cookie hash: PD4QQCYrf0TME9vIko3Xuw==
Ok, this is barely better since at least it acknowledges 'RabbitMQ' running on port 59301. But what the heck could it mean that "Erlang distribution failed"?
When I try to research this topic, I found articles saying "be sure you have matched cookies." Based on that I found this article, which claims the "cookie mismatch" does not pertain to me, because I have not created (nor intend to create) a RabbitMQ cluster.
What should I do?
I had this same problem today. There were no cookie or firewall problems and windows reported that the service was running successfully. This is what finally fixed it:
Run RabbitMQ sbin command prompt as administrator.
Run "rabbitmq-service remove"
Run "rabbitmq-service install"
For some reason the service set up by the installer did not configure several registry entries. Running this set them correctly and allowed the service to run.
One thing I noticed was that before I did this, there was no description of the service in the Windows Services view. After installing with the rabbitmq-service command, the description was visible. This might be a quick indicator if you are having the same problem.
As #eddyP commented, I had two different Erlang cookie files:
A server cookie file, located at $env:WINDIR\system32\config\systemprofile\.erlang.cookie (prior to Erlang 20.2 it was located at $env:WINDIR\.erlang.cookie).
A client cookie file, located at $env:USERPROFILE\.erlang.cookie.
Copying the server cookie file over the client one, so that both files were the same, fixed the problem for me.
For further details, see "How Nodes (and CLI tools) Authenticate to Each Other: the Erlang Cookie".
From RabbitMQ Command Prompt sbin (run as administrator) execute this command:
rabbitmq-server restart
In Windown, For some reason delete all folder in c:\Users\xxx\AppData\Roaming\RabbitMQ\db\ (xxx is your username)
then flow #Jerdev answer and
start rabbitmq net start rabbitmq
check rabbitmq service rabbitmqctl status
The same question on the RabbitMQ mailing list: https://groups.google.com/forum/#!topic/rabbitmq-users/0s1ExFhl4hM.
The Erlang cookie is used by rabbitmqctl as well as server nodes, so it may need being taken care of (placed in the correct location).
See "Installing as a non-administrator user leaves .erlang.cookie in the wrong place" on Windows quirks.
I resolve my problem doing this in Windows 10.
Execute RabbitMQ Command Prompt (sbin dir) as administrator.
Execute "rabbitmq-service remove" in (RabbitMQ Command Prompt).
Execute %AppData% in Run Dialog Box of Windows.
Delete all files in RabbitMQ folder.
Execute "rabbitmq-service install" in (RabbitMQ Command Prompt).
Execute "rabbitmqctl start_app" in (RabbitMQ Command Prompt).
If you come here looking for a linux answer for the same error message, try
sudo service rabbitmq-server start
(which is not a blocking command)
Just do the following:
Uninstall rabbitmq and erlang.
delete the rabbitmq folder existing in your appdata (if you dont
know the appdata location, just type echo %AppData% in the command
prompt)
Then install erlang first and then rabbitmq.
After installing, enable the management plugin using below command:
rabbitmq-plugins enable rabbitmq_management
For me the cookies didnt match, like the other comments but the locations was in a different path for those having the same issue as me C:\Windows\System32\config\systemprofile
That is happening because rabbit MQ is not being installed correctly on Windows (and this error is misleading!). So to solve it do the following:
type "cmd" in Cortana search or in "Run" for older version of Windows
right click on in and choose "Run as Administrator"
go to rabbit's sbin folder (cd "C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin")
run: rabbitmq-service remove
run: rabbitmq-service install
now you can run
6. rabbitmq-plugins enable rabbitmq_management
7. rabbitmq-service start
8. and, finally, run: start http://localhost:15672
9. log on as user "guest" with password: "guest" and that's it. Happy Rabbiting!
I missed restarting my WINDOWS OS and then deleting the old version of ERLANG (which I uninstalled before restarting).
Somehow the fresh installation of Rabbit was referring to the old (un-installed version) and all the mismatch was happening. Clue was the 'services' referred Rabbit from the old ERLANG version.
This is how I resolved the error in my Windows 8 system:
Check for a syntax error in the rabbitmq.config file placed in the AppData folder for Windows.
How to check if there is any syntax error?
You can run rabbitmq-server restart from sbin folder in:
Program Files/RabbitMQ/rabbitmq_server_x.x/sbin/.
Replace the content of the rabbitmq.config with rabbitmq.config.example.
You may find the rabbitmq.config.example in:
Program Files/RabbitMQ/rabbitmq_server_x.x/etc/
Warning, you will lose the configuration you have saved previously with rabbitmq.
After changing the files, just hit
rabbitmq-server restart
in the sbin folder mentioned above.
I have glassfish v3 on windows 7 installed, but it won't start on 8080. I get typical dead page when I go to 8080 like you would expect if it's not running.
I tried to start it manually.
C:\glassfish3\bin
asadmin start-domain and what i get is "system cannot find the path specified"
I searched hi and low for an answer but most questions involve glassfish not starting because the port is not free. however that's not my issue.
I've tried reinstalling about a half dozen times and even rebooting. nothing changes
An alternative answer:
Download the zip version here:
http://download.java.net/glassfish/3.1.2/release/glassfish-3.1.2.zip
Unzip this to c:\glassfish3
This command will work:
C:\glassfish3\bin\asadmin.bat start-domain domain1
Its a configuration issue, when you try to install glassfish server from the installer sans bundled jdk,simply go to "\glassfish3\glassfish\config", set AS_JAVA to jdk home dir in asenv.bat file, re-run the installation, chose custom installation and "configure an existing installation" and you are done.
For more info:http://java.net/jira/browse/GLASSFISH-16155.
It looks like you forgot a slash in your command. The error your getting isn't a glassfish error, it's a DOS error.
try:
C:\glassfish3\bin\asadmin.bat start-domain domain1
or
C:\glassfish3\bin\asadmin start-domain domain1
Hi I was facing the same issue. I am able to resolve the same issue by following below steps:
Go to \glassfish\config (Note: In my case it is c:\glassfish3\glassfish\config)
Now open asenv.bat in notepad.
Make the value of AS_JAVA same as JAVA_HOME environment variable.
Now open command prompt and go to the bin folder and run asadmin start-domain domain1.
If you are getting error that no domain exist then create new domain by following below link:
