I'm using couchbase the lastest version.
Must I open port all of range 21100 to 21199?
Do I have any problem to open port only one of them?(ex, 21100 port)
please help me.
Yes you have to open these ports. They are used by Erlang for the inter-nodes communication.

I've been trying to find a good free server for our school project so I've decided to try ec2 and just make my pc the server that I will use. I've managed to install my node server onto the ec2. I can post requests using postman but when I'm trying to fetch data from my html file to the ec2 instance, it says:
Fetch API cannot load ec2xxxxxx.amazonaws.com:3000/login. URL scheme "ecxxxxxxx.compute-1.amazonaws.com" is not supported.
Is there any workaround for this? Thanks in advance!!!
Follow these steps:
Make sure your application is listening on port 3000: netstat -anp |
grep 3000 also telnet 127.0.0.1 3000
Then make sure that local firewall is configured to allow incoming access to port 3000 OR disable local firewall to do a quick test (service iptables stop). for linux, its usually iptables
Allow incoming access to port 3000 in your AWS security group.
The error is literally telling you what the problem is:
"URL scheme... is not supported"
Do you know what the "scheme" portion of a url is? This link should help, but it's the something:// portion of a uri/url.
So it indicates that you need to specify a scheme that will get you to your aws server, which is likely either http:// or https://
So to be clear your fetch needs fetch('http://ec2xxxxxx.amazonaws.com:3000/login').
My problem looks like this:
A clientele has one, with a proxy, foreclosed network. However, they want to synchronize information (using odbc-connector) with a database server running on there own Linux server. Unfortunately, only very few ports are open and they do not want to open any further ports.
My idea is that I run the database communication over one of the open ports.
Since I've not done something like this so far, and I'm not really got any further with google search. So I was unfortunately not been able to change the default port of the database server in Plesk on e.g. Port 8080.
I'll be very happy about suggestions:
Either via help changing the port OR also over other ideas, how this problem could be solved more easily.
Thank you in advance!
The system in question looks as follows:
MySQL 5.5.55
Php: 5.6
Plesk Onyx 17.0.17
Ubuntu 14.04.5 LTS
I just installed Couchbase Server 3.0.2 on Windows 8.1. The Installation went through successfully but I am unable to access http://localhost:8091/index.html.
"Google Chrome's connection attempt to localhost was rejected. The website may be down or your network may not be properly configured."
I tried to check if anything listening on that port using the command.
netstat -an -p tcp
But found nothing is listening on that port and the closest port i found was 8092, so thought may port has changed so when i try to browse on that port i got a json response as below.
{"code":404,"status":"fail","message":"controller_not_provided","ResultDate":"2015-02-06T17:13:23.2551859Z","Progress":-1,"Result":"No controller provided."}
please check the couchbase service form the windows control panel. sometimes it will not start the service automatically ,it may be manual. start the service manually , if not started then check the localhost url.
you can also start the service form the desktop icon. double click on the couchbase icon it will start the service automatically and it will open the url in your default browser.
if still facing the problem not able to start the couchbase server , follow the
.link
it describe each and every steps of the couch base installation process.
I have a mac computer and I run "xampp" my sql server on it.
It works great locally but I want to access it from lets say my iPhone thats use 3g connection.
I'm using the external ip of my computer but don't get to the sql server.
I opened the 3306 port I'm my router but still doest work...
what should I do? (I'm using mac).
thanks for help
You might need to use port forwarding and forward all traffic to port 3306 to your computer that runs mysql.
http://portforward.com/english/routers/port_forwarding/
I have enabled this through windows Firewall. (I use Avast Free which doesn't have a free firewall) and I have went onto the BT router to port forward this too. Yet I still get system error 10060. I have downloaded PfPortchecker and checked port 3306 and apparently it's still not open.
I am pretty clueless on what to do here, any help is appreciated cheers.
If both MySQL Workbench and your MySQL server run on the same machine then you don't need to open any port on the modem or in the firewall. Focus on problems on your local machine.
First thing to check is: is your server actually running? Is there a service that starts the MySQL server? What setup is that? Did you install the server via the MySQL Windows Installer? If the server is running check the config file if TCP/IP networking is disabled for some weird reason (it should not, but who knows). If that is disabled you can only connect via a named pipe to your server.
Next step is to check is that the user you use to connect is actually allowed to connect from the local machine. Jeremy is right here, it matters if you use localhost or 127.0.0.1, especially if IPv6 is enabled on the box (where localhost resolves to ::1, instead of 127.0.0.1).
