SSL springboot Verify the connector's configuration - ssl

I want to use ssl in my springboot app. I use this tutorial but when I try up start my app gives me this error:
***************************
APPLICATION FAILED TO START
***************************
Description:
The Tomcat connector configured to listen on port 8443 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 8443, or configure this application to listen on another port.
And my application.properties
#ssl
server.port=8443
server.ssl.key-alias=alias
server.ssl.key-password=password
server.ssl.key-store=classpath:keystore.jks
server.ssl.key-store-provider=SUN
server.ssl.key-store-type=JKS
Or do you know another way to do SSL trusted?

Generate the key with command line running in admin mode.

Command not found while starting the secured zookeeper CLI to connect to ZK server

I have configured the ZK Server to use SSL (signed cert, trust store,keystore, modified zookeeper.properties all setup done and good). Zookeeper starts and listens on the port 2182 for SSL requests and no errors in the zookeeper and kafka server logs.
#new properties added in kafka/config/zookeeper.properties
secureClientPort=2182
authProvider.x509=org.apache.zookeeper.server.auth.X509AuthenticationProvider
serverCnxnFactory=org.apache.zookeeper.server.NettyServerCnxnFactory
ssl.trustStore.location=/path/to/ssl/kafka.zookeeper.truststore.jks
ssl.trustStore.password=serversecret
ssl.keyStore.location=/path/to/ssl/kafka.zookeeper.keystore.jks
ssl.keyStore.password=serversecret
ssl.clientAuth=need
Now to connect to secure zookeeper using ZK-CLI I am following similar approach. Create zk-client cert, get it signed, create truststore and keystore for the same. Create the properties file and trying to connect to ZK server but I get an error
Command not found: Command not found /path/to/ssl/zookeeper-client.properties
$ kafka/bin/zookeeper-shell.sh localhost:2182 -zk-tls-config-file /Users/path/to/ssl/zookeeper-client.properties
Connecting to localhost:2182
ZooKeeper -server host:port cmd args
addauth scheme auth
close
.....
Command not found: Command not found /Users/path/to/ssl/zookeeper-client.properties
My zookeeper-client.properties looks like this
$cat /Users/path/to/ssl/zookeeper-client.properties
#zookeeper.connect=localhost:2182
zookeeper.clientCnxnSocket=org.apache.zookeeper.ClientCnxnSocketNetty
zookeeper.ssl.client.enable=true
zookeeper.ssl.protocol=TLSv1.2
zookeeper.ssl.truststore.location=/Users/path/to/ssl/kafka.zookeeper-client.truststore.jks
zookeeper.ssl.truststore.password=serversecret
zookeeper.ssl.keystore.location=/Users/path/to/ssl/kafka.zookeeper-client.keystore.jks
zookeeper.ssl.keystore.password=serversecret
Kafka Server logs at the start of the ZK.

...
When I try to connect to port 2182 with the zk-client the server logs doesn't show an entry (probably because it is not able to connect as the command to initiate connection fails)
I am using kafka_2.12 version and it has zookeeper-3.5.7
What am I missing here? To me configurations look as expected and the zk-cli shouldn't throw

Thanks,

I think the problem is that your cli is running from older version that does not yet support this parameter, check your execution path , are you truly executing from the "current" version?

Weblogic NodeManager Start Failure

I've setup a weblogic cluster with 2 managed servers.In order to configure node manager on both nodes i've followed the related article :
http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/wls/12c/12_2_1/01-12-001-ConfiguringandUsingNodeManager/Configuring_and_Using_NM.html
with the following configuration :
Machine-0 :
DomainsFile=/u01/app/oracle/config/domains/base_domain/Machine-
0/nodemanager.domains
LogLimit=0
PropertiesVersion=12.1.3
AuthenticationEnabled=true
NodeManagerHome=/u01/app/oracle/config/domains/base_domain/Machine-0
JavaHome=/opt/jdk1.8.0_131
LogLevel=INFO
DomainsFileEnabled=true
StartScriptName=startWebLogic.sh
ListenAddress=localhost
NativeVersionEnabled=true
ListenPort=5558
LogToStderr=true
SecureListener=false
LogCount=1
StopScriptEnabled=false
QuitEnabled=false
LogAppend=true
StateCheckInterval=500
CrashRecoveryEnabled=false
StartScriptEnabled=true
LogFile=/u01/app/oracle/config/domains/base_domain/Machine-
0/nodemanager.log
LogFormatter=weblogic.nodemanager.server.LogFormatter
ListenBacklog=50
Machine-1 (the second managed server) has the same configuration with the exceptions of ports (5557) and name.
Although node manager is successfully started on both machines (startNodeManager.sh on machine-0 and machine-1) from admin console on Machine-0 the following error occurs and node manager doesnt start :
weblogic.nodemanager.NMConnectException
nodemanager.log of Machine-0 has no indications of errors or any helpful stuff.
Any help would be appreciated.
thanks in advance
These are the things that I usually check when I am setting up a new WebLogic domain:
It is possible that the Listen Address of Machine-1 is not correct. Check the Listen Address of the machine from the WebLogic Domain Configuration. It should match the host's machine name. Using localhost might not work because the Admin Server is trying to connect to the Machine-1, which can be on the other server.
Make sure to check if the port is reachable from the Admin Server's machine.
Check that the Node Manager configuration uses Plain instead of SSL connection, as stated in your nodemanager.properties file. Under Environments > Machines, click the machine and go to Configuration Tab, Node Manager. Check if the Type is Plain and not SSL. Changing this will require a restart of the Admin Server.
Please verify the items below before you start nodemanager.
Check if the nodemanager.domains has your domain name listed.
Try to see if the ports are listening using the commands below.
netstat -an|grep 5557
netstat -an|grep 5558
Also, check if the nodemanager is reachable in weblogic console.

How to set up SSL on WildFly 9 Domain Mode?

I currently have a WildFly 9 cluster up and running with access to my application over port 8080, I would like to set up SSL and have access only on port 8443, but I cannot seem to find any documentation for where the security realm and https listener are placed in Domain mode.
I have the keystore and certificate all set up and was able to get https working in a demo using standalone mode, but I need to be able to do it in domain mode.
Can anyone help me out and share how they've accomplished this?
Solved it! It turns out for some reason JBoss was not registering my Security Realm and HTTPS listener. To do this you need to use bin/jbosscli and the commands:
RUN THE "CONNECT" COMMAND FIRST
/host=master/core-service=management/security-realm=SSLRealm/:add()
---where SSLRealm is the name of the realm
/host=master/core-service=management/security-realm=SSLRealm/server-identity=ssl/:add(keystore-path=Keystore.jks, keystore-relative-to=jboss.domain.config.dir, keystore-password=password)
---this assumes the keystore lives in the domain/configuration directory
Restart the server.
I then ran into issues figuring out the command to register the HTTPS listener, but I found the WildFly web console at serverURL:9990 has a way to do it too:
Once logged in to the webconsole
Configuration->Profiles->for each profile which is used->Undertow->HTTP->View
From there
HTTP Server->default-server->view
Finally
HTTPS Listener->ADD enter a name like: default-https, Security Realm: the name chosen for the security realm (for this example SSLRealm), Socket Binding: https and click save
Restart again
You should now have access at your serversURL:8443
To set it up on slave servers you should only need to copy the keystore to each slave servers domain/configuration and then add the security realm replacing /host=master/ with /host=slave/ in the command. And then restart the server.
Double check the Domain.xml file on the slave has the https listener you created originally in the webconsole (it should automatically be put into all of the clusters domain.xml files)

SailsJS on production - Error: listen EADDRINUSE

I have a VPS server with CentOS and Apache server.
But I want to run my node.js applications too. I am using sails.js
This sails application is trying to listen to port 80 of specified host.
Here is error (after sails lift running):
debug: Starting server in /var/www/user/data/nodeprojects/projectname...
info - socket.io started
debug: Restricting access to host: projectname.com
warn - error raised: Error: listen EADDRINUSE
warn:
warn: Server doesn't seem to be starting.
warn: Perhaps something else is already running on port 80 with hostname projectname.com?
What is the problem? Can I run both apache and nodejs servers on one server with one port (80)?
No, you cannot.
When a server process opens a TCP port to answer requests, it has exclusive use of that port. So, you cannot run both SailsJS and Apache servers on the same port.
Having said that, you can do lots of interesting things with Apache, such as proxying specific requests to other servers running on different ports.
A typical setup would have Apache on port 80 and SailsJS on port 8000 (or some other available port) where Apache would forward requests to certain URLs to SailsJS and then forward the reply from SailsJS back to the browser.
See either configuring Apache on Mountain Lion proxying to Node.js or http://thatextramile.be/blog/2012/01/hosting-a-node-js-site-through-apache for example implementations of this approach.
you cannot use same port for different application. NodeJS can use any open port. What you need todo is port forwarding for your app. :)

Cannot bind to TCP port 443 because it is in use by another process Virtual Machine Manager

i created a Template with my Virtual Machine Manager. ( SystemCenter 2012 SP1 ) I am trying to deploy this to my hyper-v host. After a wihle , the process is going to stop with an error:
Error (22042) The service (123) was not successfully deployed. Review
the event log to determine the cause before you take corrective
action.
Recommended Action The deployment can be restarted by retrying the
job.
Error (12702) Cannot bind to TCP port 443 because it is in use by
another process on the vmmanger.de.myserver.corp server.
Recommended Action Wait until the other process is completed, and then
try the operation again.

Do you have any other network applications running? You can check this with netstat on the command prompt. Port 443 is the default port for HTTPS servers, do you have one running on your computer? When you've found the process with netstat, end it and try this again - it should work afterwards.
port 443 is bound for https web communications.
