I am building an OSM tile server as per directions available here: https://switch2osm.org/manually-building-a-tile-server-16-04-2-lts/ on an Amazon EC2 instance with Ubuntu 16-04 LTS.
Everything is working well until the step of starting renderd as a service:
sudo /etc/init.d/renderd start
This returns an error of: "Job for renderd.service failed because the control process exited with error code. See "systemctl status renderd.service" and "journalctl -xe" for details."
Checking the details mentioned gives messages like:
"renderd.service: Control process exited, code=exited status=203"
"The error number returned by this process is 8."
I can however run renderd directly no problem as below, and can even (slowly) load tiles into a leaflet map, I just cannot run it as a service.
sudo -u username renderd -f -c /usr/local/etc/renderd.conf
I have also tried changing to my rendering user and starting the service from there, but then I get a password prompt for user ubuntu (there isn't one).
What else can I test out or investigate to find out what the problem is?
I decided to start building my server again from scratch, this time also using information from other tutorials: https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04 and https://ircama.github.io/osm-carto-tutorials/tile-server-ubuntu
Following those instructions, renderd now runs as a service. The main difference I noticed was those tutorials above use https://github.com/openstreetmap/mod_tile.git rather than the
https://github.com/SomeoneElseOSM/mod_tile.git source I used before, so perhaps the settings of the branched mod_tile were not compatible with my server.

I am trying to run an azure container instance but it appears to be getting killed off the second I run it. This works fine in 2 other resource groups but not my production resource group where I see the following:
In events I see 'Successfully pulled image
selenium/standalone-chrome:latest' with count 1 and then 'Started
container' and then 'Killing container' with count 31. The times for
started and killed are the same.
In logs, it just says 'No logs available'
The metrics for CPU and memory on the container never show any change from zero.
Looked at this article but the proposed solution didn't work: Azure Container Group Instance I have tried putting on both an empty directory volume and 2Gb of ram as advised here: https://github.com/SeleniumHQ/docker-selenium but nothing works.
This is the code I am using to create the container:
containerGroup = await azure.ContainerGroups.Define(containerName)
.WithRegion("West Europe")
.WithExistingResourceGroup(configuration.ContainerResourceGroup)
.WithLinux()
.WithPublicImageRegistryOnly()
.WithEmptyDirectoryVolume("devshm")
.DefineContainerInstance(containerName)
.WithImage("selenium/standalone-chrome")
.WithExternalTcpPorts(4444)
.WithVolumeMountSetting("devshm", "/dev/shm")
.WithMemorySizeInGB(2)
.Attach()
.WithDnsPrefix(configuration.AppServiceName + "container")
.WithRestartPolicy(ContainerGroupRestartPolicy.OnFailure)
.CreateAsync(cancellationToken);
How do I debug what is going wrong?
What is wrong with the container?
In case this helps someone I renamed the "containerName" parameter in the above example from myinstance to myinstance1 and changed the region from West Europe to UK South. This fixed the issue. I can only think that Azure caches instances somehow to reduce start up times and the cached image I was using was poisoned somehow.
One issue could be the restart policy - have a look at the Microsoft restart policy troubleshooting on Microsoft's ACI troubleshooting page. According to the website under the Container continually exits and restarts (no long-running process) header in the page:
Container groups default to a restart policy of Always, so containers
in the container group always restart after they run to completion.
You may need to change this to OnFailure or Never if you intend to run
task-based containers. If you specify OnFailure and still see
continual restarts, there might be an issue with the application or
script executed in your container.
In your case you may need to adjust the code as follows using the withStartingCommand:
containerGroup = await azure.ContainerGroups.Define(containerName)
.WithRegion("West Europe")
.WithExistingResourceGroup(configuration.ContainerResourceGroup)
.WithLinux()
.WithPublicImageRegistryOnly()
.WithEmptyDirectoryVolume("devshm")
.DefineContainerInstance(containerName)
.WithImage("selenium/standalone-chrome")
.WithExternalTcpPorts(4444)
.WithVolumeMountSetting("devshm", "/dev/shm")
.WithMemorySizeInGB(2)
.WithStartingCommandLine("tail")
.WithStartingCommandLine("-f")
.WithStartingCommandLine("/dev/null")
.Attach()
.WithDnsPrefix(configuration.AppServiceName + "container")
.WithRestartPolicy(ContainerGroupRestartPolicy.OnFailure)
.CreateAsync(cancellationToken);
This link is helpful for this issue.
--command-line
linux => "tail -f /dev/null"
windows => "ping -t localhost"
# .yml
command: tail -f /dev/null
It will keep your azure instance running.
As now azure do have a endpoint to connect/analyze the process on.
On a new installation of cassandra 3.0.20 on redhat 7 I can not list roles. I have tried the option of fixing /etc/alternatives/cassandra/cassandra.yaml with...
authenticator: PasswordAuthenticator
and then restart the service.
still when I run a simple command like LIST ROLES I get the following error.
cassandra#cqlsh> list roles;
Unauthorized: Error from server: code=2100 [Unauthorized] message="You have to be logged in and not anonymous to perform this request"
It turns out that systemctl was not completely stopping cassandra due to weirdness with Redhat 7 and the init file. Therefore the changes to my cassandra.yaml were not taking effect.
Once I killed cassandra, made a proper cassandra.service and restarted the desired settings took effect, and I am able to run operations like "LIST ROLES;" normally.
Run environment ：linux （CentOS 7）, JDK 1.8, & ActiveMQ 5.15
I started Activemq then visit the management page with Chrome，when I try to log in with the default username & password I get the following error;
HTTP ERROR: 503
Problem accessing /admin/. Reason:
Service Unavailable Powered by Jetty://
How can I resolve this problem?
I was getting this same error. It turns out that I had run it as root user originally, then later I stopped it and ran it as a non-root user. Certain data files that had been created and owned by the original root instance were not accessible to the non-root user.
Check the ownership of the files, and change them if necessary to match the user that the broker is running as.
Had the same issue.
Maybe something went wrong the extraction of the package.
I downloaded this:
wget https://archive.apache.org/dist/activemq/5.15.0/apache-activemq-5.15.0-bin.tar.gz
and extracted it with:
sudo tar -zxvf apache-activemq-5.15.0-bin.tar.gz -C /opt
then it worked for me.
My two cents:
I start with the activemq in Ubuntu Repo, but then later change to binary package from official website.
In my case, the repo version left an /etc/default/activemq config file, which runs activemq with user "activemq". It turns out in previous experiments, I did not kill the old processes running under "activemq" when I start activemq under my own user name. There are two activemq processes running under different user names, and when connecting to admin console, I have a 503.
I delete the /etc/default/activemq file, and kill all activemq processes running under "activemq", then restart activemq with my user name, the 503 is gone.
i build spinnaker using docker-compose follow here
but it always redirect to localhost, how can i fix this.
e.g.
http://localhost:8084/auth/redirect?to=http%3A%2F%2F192.168.99.100%3A9000%2F%23%2Finfrastructure
i set the host:0.0.0.0 in spinnaker-local.yml and configured deck apache2 with proxyPreserve=On, it's not working.
where is the configuration about 'redirect'?
All containers running well but fiat gets error mesages, like this:
WARN 1 --- [ecutionAction-1] c.n.s.fiat.roles.UserRolesSyncer : [] User permission sync failed. Server status is DOWN. Trying again in 10000 ms. Cause:(Provider: DefaultServiceAccountProvider) retrofit.RetrofitError: unexpected url: front50/serviceAccounts
i'm sure set fiat false, is this matter?
thanks.
The docker-compose link project is not available anymore. That deployment type is not supported anymore.
The easiest way i suggest for people to get started quick is by using Armory Open source Minnaker. It runs on top of a K3S small cluster and contains a functional spinnaker deployment.
Great way to get started.
I tried the debian local deployment and it failed all the time.
Enjoy your CD operations.
I'm trying to follow the steps in the RabbitMQ docs here to get clustering with SSL working on Windows. I'm noticing though that the "rabbitmqctl status" command starts failing after the environment variables defined in those steps are set. I'm getting the following error when executing "rabbitmqctl status":
Error: unable to connect to node 'rabbit#server1': nodedown
I've already configured RabbitMQ to use TLS 1.2 and have verified that it's working. I've ensured that my Erlang 18 cookie is the same in the user directory C:\users\me and C:\Windows on the machine, but the error persists, and is stopping other servers from clustering with it. The docs say that the Windows SSL Cluster setup is "Coming soon"... Here are the steps I've taken so far on server1. I think that Erlang wants forward slashes in the paths - this matches the rabbit.config SSL settings.
Combined the contents of my server\cert.pem and server\key.pem into rabbit.pem via the command "type server\cert.pem server\key.pem > server\rabbit.pem"
Created environment variable ERL_SSL_PATH and set to: "C:/Program
Files/erl7.0/lib/ssl-7.0/ebin"
Created environment variable RABBITMQ_CTL_ERL_ARGS and set to: -pa "%ERL_SSL_PATH%" -proto_dist inet_tls -ssl_dist_opt server_certfile C:/OpenSSL-Win64/server/rabbit.pem -ssl_dist_opt server_secure_renegotiate true client_secure_renegotiate true
Created environment variable RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS and set to same value as RABBITMQ_CTL_ERL_ARGS
Copied the erlang cookie at C:\Windows.erlang.cookie to my local user profile directory.
Restarted rabbit using rabbitmq-service start
At this point, on server1, "rabbitmqctl status" no longer works. Attempts to try to join server2 to server1 result in a "node down" error.
Edit 1: I can't get the initial step in the docs working to ask Erlang to report its SSL directory on Windows in order to set ERL_SSL_PATH correctly. Erlang is installed at C:\Program Files\erl7.0 on my server.
Edit 2: Using werl.exe (at C:\Program Files\erl7.0\bin\werl.exe), I was able to issue a command "Foo=io:format(code:lib_dir(ssl, ebin))." and it reported the path as: c:/Program Files/erl7.0/lib/ssl-7.0/ebin. However, this doesn't seem to be the cause of the this issue since that's already what I was using.
Thanks,
Andy
For environment changes to take effect on Windows, the service must be
re-installed. It is not sufficient to restart the service. This can be
done using the installer or on the command line with administrator
permissions
(source)
This will do:
rabbitmq-service.bat stop
rabbitmq-service.bat remove
rabbitmq-service.bat install
rabbitmq-service.bat start
Also, if while the node you're working on is down, the other cluster nodes were running, their state might be assumed to have gone out of sync. In that case, the node might fail to start up and you might need to:
rabbitmqctl force_boot
Check the logs to confirm. (at %RABBIT_BASE%\log\rabbit#server.log)
Late answer but, hopefully this could help a searcher...
