I'm trying to setup a private name serve on a hostgator vps account level 1.
I found this tutorial how to do it.
In step 5 I have to start the named server with:
/etc/init.d/named start
which results in:
Starting named: named: already running [FAILED]
restart instead of start works.
then In step 7 I have to login to the second name server and change:
/var/named/chroot/etc/named.conf
but if I do change it it changes on both servers.
And last is when I'm checking if its been setup correctly in step 10 with:
cat /etc/resolv.conf
it results in 2 totally different ip's that aren't the same as I specified in earlier steps.
Any idea of how I can get my private name server up and running?
Tthe server uses CentOS 5.9

I am relativity new to running run deck and i have been stuck on the same issue for the last two days. I am trying to do the simple task of changing the IP address from a local host address to another ip. I have already altered framework.server.name, .hostname, .port, .serverurl. I also changed the rund-deck-configs.properties grails.serverURL to my ip address. i have tried different ips. While i have changed all o9f those (after rebooting ubuntu) i get an error when starting rundeck that something is using port 4440, but i have already moved everything to port 22950.
EDIT: The issue had nothing to do with rundeck but my lack of understanding with the server ip section. To fix the issue all i did was assign the address of my computer to the amended files and it worked. Hope this helps anyone else with the same issues
Comment: ubuntu 20.10, turned off firewall, and am on rundeck 3.3.2-20200817
For WAR based installation follow these steps.
Check the system requirements, in your case, focus on your JDK version (3.3.X branch works with JDK 8 and JDK 11), then download Rundeck WAR file and save it in some directory.
Launch Rundeck for the first time to generate all files, for that do: java -jar rundeck-3.3.2-20200817.war, after that stop it with ctrl+c.
Change the grails.serverURL parameter on rundeck-config.properties file (at /your/rundeck/path/server/config path) with your custom port, for example, grails.serverURL=http://your-ip:5555. Also, set server.address to 0.0.0.0 to listen conections from outside: server.address=0.0.0.0.
Change the framework.server.port and framework.server.url on your framework.properties file accodingly to your custom port (at /your/rundeck/path/etc path), on my example framework.server.port = 5555 and framework.server.url = http://your-ip:5555
Now launch Rundeck with: java -jar -Dserver.http.port=5555 rundeck-3.3.2-20200817.war
Now, you can see Rundeck running on a custom port (5555 in my example).
I'm trying to deploy an infinisppan cluster (2 machines) using the domain mode. But I can't find any working example of domain.xml and host.xml config file.
This cluster would be used by keycloak as a cache server
Any luck one of you already work on this ?
You need to download infinispan 9.4.14 (or any 9.4) and start the bin/domain.sh [bat] script.
That's it you have a running domain with two servers.
If you want to add a second machine you need to copy the server and start the domain script by passing "--host-config=host-slave.xml" also you need to set "jboss.domain.master.address=" with "-D" to let the process know where the domain master is.
Anothe option is to move host-slave.xml-->host.xml and edit the domain-controller discovery-options.
More information can be found here -> http://infinispan.org/docs/stable/server_guide/server_guide.html#domain_mode
I have setup the apache cloudstack on CentOS 6.8 machine following quick installation guide. The management server and KVM are setup on the same machine. The management server is running without problems. I was able to add zone, pod, cluster, primary and secondary storage from the web interface. But when I tried to add an instance it is not showing any templates in the second stage as you can see in the screenshot
However, I am able to see two templates under Templates link in web UI.
But when I select the template and navigate to Zone tab, I see Timeout waiting for response from storage host and Ready field shows no.
When I check the management server logs, it seems there is an error when cloudstack tries to mount secondary storage for use. The below segment from cloudstack-management.log file describes this error.

Can anyone please guide me how to resolve this issue? I have been trying to figure it out for some hours now and don't know how to proceed further.
Edit 1: Please note that my LAN address was 10.103.72.50 which I assume is not /24 address. I tried to give CentOs a static IP by making the following settings in ifcg-eth0 file
DEVICE=eth0
HWADDR=52:54:00:B9:A6:C0
NM_CONTROLLED=no
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.16.10.2
NETMASK=255.255.255.0
GATEWAY=172.16.10.1
DNS1=8.8.8.8
DNS2=8.8.4.4
But doing this would stop my internet. As a workaround, I reverted these changes and installed all the packages first. Then I changed the IP to static by the same configuration settings as above and ran the cloudstack management. Everything worked fine untill I bumped into this template thing. Please help me figure out what might have went wrong
I know I'm late, but for people trying out in the future, here it goes:
I hope you have successfully added a host as mentioned in Quick Install Guide before you changed your IP to static as it autoconfigures VLANs for different traffic and creates two bridges - generally with names 'cloud' or 'cloudbr'. Cloudstack uses the Secondary Storage System VM for doing all the storage-related operations in each Zone and Cluster. What seems to be the problem is that secondary storage system vm (SSVM) is not able to communicate with the management server at port 8250. If not, try manually mounting the NFS server's mount points in the SSVM shell. You can ssh into the SSVM using the below command:
ssh -i /var/cloudstack/management/.ssh/id_rsa -p 3922 root#<Private or Link local Ip address of SSVM>
I suggest you run the /usr/local/cloud/systemvm/ssvm-check.sh after doing ssh into the secondary storage system VM (assuming it is running) and has it's private, public and link local IP address. If that doesn't help you much, take a look at the secondary storage troubleshooting docs at Cloudstack.
I would further recommend, if anyone in future runs into similar issues, check if the SSVM is running and is in "Up" state in the System VMs section of Infrastructure tab and that you are able to open up a console session of it from the browser. If that is working go on to run the ssvm-check.sh script mentioned above which systematically checks each and every point of operation that SSVM executes. Even if console session cannot be opened up, you can still ssh using the link local IP address of SSVM which can be accessed by opening up details of SSVM and than execute the script. If it says, it cannot communicate with Management Server at port 8250, I recommend you check the iptables rules of management server and make sure all traffic is allowed at port 8250. A custom command to check the same is nc -v <mngmnt-server-ip> 8250. You can do a simple search and learn how to add port 8250 in your iptables rules if that is not opened. Next, you mentioned you used CentOS 6.8, so it probably uses older versions of nfs, so execute exportfs -a in your NFS server to make sure all the NFS shares are properly exported and there are no errors. I would recommend that you wait for the downloading status of CentOS 5.5 no GUI kvm template to be complete and its Ready status shown as 'Yes' before you start importing your own templates and ISOs to execute on VMs. Finally, if your ssvm-check.sh script shows everything is good and the download still does not start, you can run the command: service cloud restart and actually check if the service has gotten a PID using service cloud status as the older versions of system vm templates sometimes need us to manually start the cloud service using service cloud start even after the restart command. Restarting the cloud service in SSVM triggers the restart of downloading of all remaining templates and ISOs. Side note: the system VMs uses a Debian kernel if you want to do some more troubleshooting. Hope this helps.
I'm trying to setup a cell and a collective in a WAS for bluemix service. I've found a few steps online for generic liberty setup, but nothing specific for a bluemix collective or cell. Can someone point me in the right direction?
At a high level, you should be able to do the following for a Cell:
Login to the Admin Console as wsadmin
Create a server.
Open all the ports on each host for each server created by running the openFirewallPorts.sh script. Below, you will find the standard ports for a new server given that only one server exists on each host You may need to open more ports for additional servers on the same host since ports can be unique per server. Try the following:
cd WAS_HOME/virtual/bin
export serverPorts=2810:TCP,2810:UDP,8880:TCP,8880:UDP,9101:TCP,9101:UDP,9061:TCP,9061:UDP,9080:TCP,9080:UDP,9354:TCP,9354:UDP,9044:TCP,9044:UDP,9443:TCP,9443:UDP,5060:TCP,5060:UDP,5061:TCP,5061:UDP,11005:TCP,11005:UDP,11007:TCP,11007:UDP,9633:TCP,9633:UDP,7276:TCP,7276:UDP,7286:TCP,7286:UDP,5558:TCP,5558:UDP,5578:TCP,5578:UDP
sudo ./openFirewallPorts.sh -ports $serverPorts -persist true
Start your server.
Deploy your application.
There are a few slight differences for a Liberty Collective, but again, at a high level, you should be able to try the following:
Switch your user to wsadmin or ssh to your host using wsadmin / password
On each host, create a server and join it to the collective. Be sure to use the full host name of the controller for the --host parameter.
cd WAS_HOME/bin
./server create server
./collective join server --host=yourhostname --port=9443 --user=wsadmin --password=xxxxxxxx --keystorePassword=yyyyyyyy
Accept the chain certificate (y/n) y
Save the output from each join so you can paste it into each host's application server.xml file before deploying your application.
Install the features required by your application on each host. The features listed below are an example.
cd /opt/IBM/WebSphere/Liberty/bin
./featureManager install --acceptLicense ejblite-3.2 websocket-1.0 jsp-2.3 jdbc-4.1 jaxrs-2.0 cdi-1.2 beanValidation-1.1
NOTE: Output from this command will contain messages similar to:
chmod: changing permissions of
`/opt/IBM/WebSphere/Liberty/bin/featureManager': Operation not
permitted
This is OK. You should see this message upon completion:
Product validation completed successfully.
Update your application's server.xml file with the information saved in Step 2.
Start your server.
Deploy your application.
Verify your application is reachable :9080/appname
I'm trying to setup a pipeline following the guide on this website.
I setup the glassfish servers as shown in the guide. When I run one of the servers there is no problem. But as I run a second server it gives the following error:
http://pastebin.com/jPm7gfGt
For comparison the first server I run gives the following output:
http://pastebin.com/xwqF5v62
I'm a bit confused on what to do next. It seems a port is in use?
Can You try to create domains steb-by-step. I.e create first one - production than start it with
asadmin start-domain production.
Than create next one.
In that case glassfish can detect already used ports and select other numbers in second and next domains.
Hope this helps
