We let the golem package automatically create a Dockerfile for us and can run the docker image and see the app at the root directory: http://localhost:3838/?...
But we would like the app to appear in a subdirectory like http://localhost:3838/myApp/v1/?... so that we can set up the necessary proxying for Apache and have this and other apps all available from a single server.
We can manually edit the Dockerfile to copy a shiny-server.conf file with the following information:
# Define a server that listens on port 3838
server {
listen 3838;
# Define a location at the base URL
location /myApp/v1/ {
# Host the directory of Shiny Apps stored in this directory
site_dir /srv/shiny-server;
# Log all Shiny output to files in this directory
log_dir /var/log/shiny-server;
}
}
The above solution feels like a hack and we are hoping there is functionality inside of golem that will allow us to set the subdirectory at which the app will appear.
Unfortunately there is no way to include an nginx configuration inside the Dockerfile programmatically: {golem} tries to help with the creation of the file, but some things still need to be done manually.
Also, note that {golem} doesn't create a Dockerfile with a shiny server in it, it creates a standalone docker image that launches the app, so there is no shiny server running, just an R process. {shiny} being what it is, there is no way to natively run it on a given path, it's always at the root, on a port.
That being said, what you can do is either edit the dockerfile so that it also bundle nginx (or any other load balancer), so that you can serve the app on a path, or serve your application on another port, using the port argument of add_dockerfile(): that might be easier to configure it with you Apache proxy.

We installed fuse-online 7.4 on openshift 3.11. We created an integration containing an OpenApiProvider connection and an SQL connection.
When we publish the integration, the build fails with the following error:
"repo1.maven.org: Name or service not known: Unknown host repo1.maven.org: Name or service not known"
Openshift is installed behing an enterprise http proxy
The image registry.access.redhat.com/fuse7/fuse-ignite-s2i is pulled correctly since docker is configured with proxy.
syndesis-server DeploymentConfig has been set with proxies environment variables
I suppose that, since the buildconfig for the integration is created dynamically, is not possible to inject HTTP_PROXY,HTTPS_PROXY,NO_PROXY env variables to the build pod.
We read https://docs.openshift.com/container-platform/3.11/install_config/http_proxies.html#s2i-builds but since we don't have any rights to modify s2i image we cannot proceed.
Is there any way to provide proxy information during during fuse-online integration build?
Finally we succeeded to inject http proxy environment variables in dynamic created build pods.
We modified syndesis-server-config config map reporting proxy variables on mavenOptions key like this:
mavenOptions: "-XX:+UseG1GC -XX:+UseStringDeduplication -Xmx310m -Dhttp.proxyHost= -Dhttp.proxyPort= -Dhttps.proxyHost= -Dhttps.proxyPort= -Dhttp.nonProxyHosts="
Thanks for the support
Let me know if you have any other idea of resolving the issue
Can you check the DNS of your network connection? Not sure why but sometimes I have to use one of the "reliable" DNS on my machine (like the 8.8.8.8 from Google) to make sure repo1.maven.org is reachable.
You can check if this is the problem trying a simple
$ ping repo1.maven.org
If that doesn't work, you have to check your DNS.
I'm a new one just start to learn and install RabbitMQ on Windows System.
I install Erlang VM and RabbitMQ in custom folder, not default folder (Both of them).
Then I have restarted my computer.
By the way，My Computer name is "NULL"
I cd to the RabbitMQ/sbin folder and use command：
rabbitmqctl status
But the return message is：
Status of node rabbit#NULL ...
Error: unable to perform an operation on node 'rabbit#NULL'.
Please see diagnostics information and suggestions below.
Most common reasons for this are:
Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
Target node is not running
In addition to the diagnostics info below:
See the CLI, clustering and networking guides on http://rabbitmq.com/documentation.html to learn more
Consult server logs on node rabbit#NULL
DIAGNOSTICS
attempted to contact: [rabbit#NULL]
rabbit#NULL:
connected to epmd (port 4369) on NULL
epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic
TCP connection succeeded but Erlang distribution failed
Authentication failed (rejected by the remote node), please check the Erlang cookie
Current node details:
node name: rabbitmqcli70#NULL
effective user's home directory: C:\Users\Jerry Song
Erlang cookie hash: 51gvGHZpn0gIK86cfiS7vp==
I have try to RESTART RabbitMQ, What I get is：
ERROR: node with name "rabbit" already running on "NULL"
By the way，My Computer name is "NULL"
And I have enable all ports in firewall.
https://groups.google.com/forum/#!topic/rabbitmq-users/a6sqrAUX_Fg
describes the problem where there is a cookie mismatch on a fresh installation of Rabbit MQ. The easy solution on windows is to synchronize the cookies
Also described here: http://www.rabbitmq.com/clustering.html#erlang-cookie
Ensure cookies are synchronized across 1, 2 and Optionally 3 below
%HOMEDRIVE%%HOMEPATH%\.erlang.cookie (usually C:\Users\%USERNAME%\.erlang.cookie for user %USERNAME%) if both the HOMEDRIVE and HOMEPATH environment variables are set
%USERPROFILE%\.erlang.cookie (usually C:\Users\%USERNAME%\.erlang.cookie) if HOMEDRIVE and HOMEPATH are not both set
For the RabbitMQ Windows service - %USERPROFILE%\.erlang.cookie (usually C:\WINDOWS\system32\config\systemprofile)
The cookie file used by the Windows service account and the user running CLI tools must be synchronized by copying the one from C:\WINDOWS\system32\config\systemprofile folder.
If you are using dedicated drive folder locations for your development tools/software in Windows10(Not the windows default location), one way you can synchronize the erlang cookie as described by https://www.rabbitmq.com/cli.html is by copying the cookie as explained below.
Please note in my case HOMEDRIVE and HOMEPATH environment variables both are not set.
After copying the "C:\Windows\system32\config\systemprofile\.erlang.cookie" to "C:\Users\%USERNAME%\.erlang.cookie" ,
the error "tcp connection succeeded but Erlang distribution failed" is resolved.
Now I am able to use "rabbitmqctl.bat status" command successfully. Hence there is no mandatory need to install in default location to resolve this error as synchronizing cookie will resolve that error.
In my case similar issue (Authentication failed because of Erlang cookies mismatch) solved by copying .erlang.cookie file from Windows system dir - C:\Windows\system32\config\systemprofile\.erlang.cookie to %HOMEDRIVE%%HOMEPATH%\.erlang.cookie (where %HOMEDRIVE% was set to H: and %HOMEPATH% to \ respectively)
Quick setup TODO for Windows, Erlang OTP 24 and RabbitMQ 3.8.19:
Download & Install Erlang [OTP 24] (needs Admin rights) from:
https://www.erlang.org/downloads
set ERLANG_HOME (should point to install dir)
Download & Install recent [3.8.19] RabbitMQ (needs Admin rights) from:
https://github.com/rabbitmq/rabbitmq-server/releases/
Follow: https://www.rabbitmq.com/install-windows.html and/or
https://www.rabbitmq.com/install-windows-manual.html
set RABBITMQ_SERVER (should point to install dir)
update %PATH% by adding: ;%RABBITMQ_SERVER%\sbin
Fix Erlang-cookie issue from above, follow: https://www.rabbitmq.com/cli.html#erlang-cookie
Enable Web UI by running command: %RABBITMQ_SERVER%/sbin/rabbitmq-plugins.bat enable rabbitmq_management
From item #8 (above) got error because of missing file: %USERPROFILEDIR%/AppData/Roaming/RabbitMQ/enabled_plugins -> had to create it and run %RABBITMQ_SERVER%/sbin/rabbitmq-plugins.bat enable rabbitmq_management again!
Run/restart on the way might be required
Finally, login to: http://localhost:15672/ (guest:guest)
, or check by cURL:
curl -i -u guest:guest http://localhost:15672/api/vhosts
should receive response like:
HTTP/1.1 200 OK
cache-control: no-cache
content-length: 186
content-security-policy: script-src 'self' 'unsafe-eval' 'unsafe-inline';
object-src 'self'

P.S. Some useful RabbitMQ CLI commands (copy-paste):
%RABBITMQ_SERVER%/sbin/rabbitmqctl start_app
%RABBITMQ_SERVER%/sbin/rabbitmqctl stop_app
%RABBITMQ_SERVER%/sbin/rabbitmqctl status
P.P.S. UPDATE: great article for this subject: https://www.journaldev.com/11655/spring-rabbitmq
I have reinstalled the RabbitMQ in my computer by using default setup folder
Then checked with the command :
rabbitmqctl status
It works now, not the problem of Erlang VM .(Means Er can install at another folder)
It will cause some problem (like this one) that I couldn't find out now if we don't use the RabbitMQ default setup require folder (C:\Program Files\RabbitMQ Server)
If anyone finds it out, I hope you can tell me why and how to fix.
How I resolved mine
It's mostly caused by cookie mismatch on a fresh installation of Rabbit MQ
follow this 2 steps
1. copy the .erlang.cookie file from C:\Windows\System32\config\systemprofile paste it into
C:\Users\["your user nameusername"] folder
2. run rabbitmq-service.bat stop and rabbitmq-service.bat start
Done it should work now when you run 'rabbitmqctl start_app' good luck.
note if you have more than one user put it in the correct user folder
In Centos.
add ip nodename pair to /etc/hosts on each node.
restart rabbitmq-server service on each slave node.
works for me.
i got error like this, i just stop my rabbitMQ with close port 25672
here syntax for linux:
kill -9 $(lsof -t -i:25672)
Error Images:
Just adding my experience if it helps others down the line.
I wrote a Powershell .ps1 script to install and configure RabbitMQ which would be used as one of the stept to provision a server with Packer.
I wrote the code on a fresh AWS W2016 Server build. It worked fine when run on the box (as administrator, from an admin PS console) but when the same code was moved over to the Packer build server, it would fall over when doing the rabbitmqctl.bat configuration steps via packer, despite both using (as far as I can tell) Administrator to run the scripts.
So this worked on the coding box:
$pathvargs = {cmd.exe /c "rabbitmqctl.bat" add_user Username Password}
Invoke-Command -ScriptBlock $pathvargs
$pathvargs = {cmd.exe /c "rabbitmqctl.bat" set_user_tags User administrator}
Invoke-Command -ScriptBlock $pathvargs
$pathvargs = {cmd.exe /c "rabbitmqctl.bat" set_permissions -p "/" User "^User-.*" ".*" ".*"}
Invoke-Command -ScriptBlock $pathvargs
Write-Host "Did RabbitMQ"
But I had to prelude this with...
copy "C:\Windows\system32\config\systemprofile\.erlang.cookie" "C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.17\sbin\.erlang.cookie"
copy "C:\Windows\system32\config\systemprofile\.erlang.cookie" $env:userprofile\.erlang.cookie -force
... On the Packer box.
I am guessing there is some context issue going on but I'm using
"winrm_username": "Administrator",
in the Packer builders block, so I thought this would suffice.
TL;DR - Use the Cookie even though it works without it in some instances.
I have encountered the same error after installing Erlang VM and RabbitMQ using the default installation folders in Windows 10. Managed to start the management and access it via HTTP, but status failed with this error.
The cookie was fine in all folders (%HOMEDRIVE%%HOMEPATH%, %USERPROFILE%, C:\WINDOWS\system32\config\systemprofile).
I had to perform a restart the Windows to make it work. After restart it set up something to run at startup + asked permission to make an exception in the firewall.
In my case, the file was at c:\\Windows\.erlang.cookie, just copied it to C:\Users{USERNAME} and all works, thanks to everyone for the hits
Another thing to check after making sure the cookie file is in all the locations.. is to realize that you installed 32 bit Erlang.. not 64..
Happened to me. Removed 32 bit Erlang and Installed 64 and rabbitmqctl status returns expected results.
I followed the steps of this tutorial:
http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercloud/doc/ega_docs/dialog_ega.shtml#ega_getstart_setup
until the step 3h (Account validation), which leads to following error:
“Client error – 407 Proxy Authorization required”.
(I am behind a company proxy)
I use Eclipse Mars 4.5.2 and IBM Bluemix Tools 1.0.10.v20160406_1758.
What i have already done:
-Of course I have Bluemix account that works perfectly fine.
-I have filled in the HTTP and HTTPS info within the Eclipse proxy settings (General->network settings) and cleared the SOCK-field. I can therefore install new software and use the eclipse marketplace for instance.
-Set the proxy at the http_proxy/https_proxy at the Windows system variables, therefore I can use the Bluemix command line tool and login to Bluemix.
-Experimenting with adding various lines at the eclipse.ini as in the following:
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provi der.filetransfer.httpclient
-Dhttp.proxyPort=8080
-Dhttp.proxyHost=YYY.com
-Dhttp.proxyUser=uid123
-Dhttp.proxyPassword=XXX
-Dhttps.proxyPort=8080
-Dhttps.proxyHost=YYY.com
-Dhttps.proxyUser=uid123
-Dhttps.proxyPassword=XXX
-Dhttp.nonProxyHosts=localhost|127.0.0.1
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.closeTimeout=3000
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.readTimeout=3000
The command "nslookup api.ng.bluemix.net" returns:
Server: AAA.de Address: aa.bbb.cd.ef
Not authorized answer:
Name: ng.bluemix.net Address: 75.126.70.44 Aliases: api.ng.bluemix.net
Any suggestions how to successfully use the Eclipse Bluemix Plugin?
Based on the error, it looks like you have authentication error on accessing the proxy itself. The Bluemix Tools does not use the command line interface (CLI) to communicate with the Bluemix server. Therefore, proxy settings are not setup in Eclipse even if you have it working using the CLI.
In Eclipse, all the proxy settings can be done from the Preference page. There is no need to change eclipse.ini so you can restore the eclipse.ini file to the original before changing the preference setting. You can find the corresponding preference page in Window>Preferences>General>Network Connection. Then, change the "Active Provider" to "Manual" and edit the HTTP and HTTPS port proxy settings as needed.
In the Edit Proxy Entry dialog, you can input the proxy authentication information by selecting Requires Authentication checkbox and input the user/password.
