I have a problem with connecting my database online.
My site is hosted on one server, and connects to a remote database that is on another server.
But it sends me the following error:
SQLSTATE [HY000] [2002] Connection refused Error
I did, however, put the exact connection information .. I do not understand why the connection is refused ..
parameters.yml:
parameters:
database_host: **.**.**.**
database_port: 3306
database_name: zip
database_driver: pdo_mysql
database_user: root
database_password: null
mailer_transport: smtp
mailer_host:
mailer_user:
mailer_password:
secret: d87fdb6ecf4089df33360b187388e33c34e12f85
I thank you in advance
Make sure the user/password are the right ones. You can use the mysql command line cli to try to connect.

i'm facing the following problem.
I've got a PostgreSQL database on a remote server. In order to access it, i need to pass through a SSH Tunnel.
So, the steps of my test are:
create the tunneling
Connect to the db
perform query / queries
I'm able to create the tunnel by using SSHLibrary, and it works:
SSHLibrary.Open Connection 10.xxx.xxx.xx
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel 9191 ${IP_DATABASE} 22
So i go on by using DatabaseLibrary to perform the connection (and i've checked all the fields are right):
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} ${IP_DATABASE} ${PORT_DB}
but i get the following error:
OperationalError: could not connect to server: Connection timed out (0x0000274C/10060)
Is the server running on host "10.xxx.xxx.xx" and accepting
TCP/IP connections on port 5432?
How can i solve it? I think i need to specify in some way that the database connection must be done by using the tunnel but i don't know how to do it.
Here's the complete test code:
*** Settings ***
Library DatabaseLibrary
Library SSHLibrary
*** Variables ***
${IP_DATABASE} 10.xxx.xxx.xx
${PORT_DB} 5432
${DB_NAME} MyNameDB
${SCHEMA_DATABASE} MySchemaDB
${USER_DB} MyUserDB
${PASSWORD_DB} MyPasswordDB
*** Keywords ***
*** Test Cases ***
Connect To DB Via SSH
SSHLibrary.Open Connection 10.xxx.xxx.xx
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel 9191 ${IP_DATABASE} 22
Sleep 2s
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} ${IP_DATABASE} ${PORT_DB}
I would like to do it by using RF, Anyone can help?
Thank's a lot
Ssh tunnels should work in a way that that you establish SSH connection to another host and expose a PORT in localhost that will then tunnel a traffic from that port in localhost to a IP/PORT in the end point of the tunnel ..
So, lets say you have a host at 192.168.100.10 where your robotframework is running and it needs to connect to a database in 192.168.50.100:
If the postgres is accessible via ssh directly:
Connect To DB Via SSH
${IP_DATABASE}= 192.168.50.100
${DB_PORT}= 5432
SSHLibrary.Open Connection ${IP_DATABASE}
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel ${DB_PORT} ${IP_DATABASE} ${DB_PORT}
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} 127.0.0.1 ${PORT_DB}
Now, if you have to use ssh jump host, eg, connect to a ssh server that will then connect to another server where postgres is running, all you need to do is change the tunnel ip address where the traffic will be forward to:
Connect To DB Via SSH
${IP_DATABASE}= 192.168.50.100
${IP_SSH_JUMPHOST}= 192.168.50.1
${DB_PORT}= 5432
SSHLibrary.Open Connection ${IP_JUMPHOST}
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel ${DB_PORT} ${IP_DATABASE} ${DB_PORT}
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} 127.0.0.1 ${PORT_DB}
I'm working on a iMac (Sierra) with phpstorm & Vagrant box laravel/homestead
I try to configure the database in the IDE but each time it failed and it said, an idea?
Connection to cmsineria#localhost failed: SSH: java.net.ConnectException: Connection refused.
SSH: java.net.ConnectException: Connection refused
I had the same issue on my Macbook Air Sierra using MAMP.
By default, MAMP use port 8889 for MySQL. Try to change port 3306 to 8889 in General.
I am trying to setup zookeeper on ec2 two instances. as given here and here.
I am trying to run zookeeper which fails with an error:

zoo.cfg as bellow
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181
server.1=localhost:2888:3888
server.2=<My ec2 private IPs>:2889:3889
also I have created myId file as on both ec2 instances - /var/lib/zookeeper/myid
I also tried to edit /ect/hosts file but still facing the same issue.
also how I can start both of the zookeeper instances by 1 command?
Note: Server get started successfully if I tried with bin/zkCli.sh start command.
Thanks in advance!
look zk log zookeeper.out，if there have connection limit error, configure the following to zoo.cfg.
# the maximum number of client connections.
# increase this if you need to handle more clients
maxClientCnxns=60
This is temporary error , for mine after some time , It gone away :-
This is my zoo.conf file ::-
Dir=../data
clientPort=2181
tickTime=2000
initLimit=5
This error occurred when I forgot to run% ZOOKEEPER_HOME% \ bin \ zkserver.cmd
By running, the problem has been resolved.
Correct this property on the server.properties
default would be localhost change it to match the zookeeper server starup ip and port
zookeeper.connect=0.0.0.0:2181
I'm having issues running an xDebug session when I've connected to the DBGp proxy successfully. I'm using both local and remote SSH tunnels for port 9000 (xdebug), and 9001 for a (xdebug DBGp client).
] The code is being debugged remotely, the xDebug server is running on an Amazon EC2 instance
] I am using Zend Studio for my local debugging client on my Macbook
] I am running a remote SSH tunnel for port 9000 "ssh ec2-user#X.X.X.X -R 9000/127.0.0.1/9000"
As of here, I'm able to successfully use xDebug, but then I run into issues running the proxy
But then I start running into issues running the proy:
] I then run the dbgp proxy on the remote server
./pydbgpproxy

] I then setup a local SSH tunnel for port 9001 - "ssh ec2-user#X.X.X.X -L 9001/127.0.0.1/9001"

It actually shows those lines like "INFO: dbgp.proxy: connection from 127.0.0.1:39179 [<main.sessionProxy instance at 0x122ec68>]" almost 50x more than what I copied and pasted here for brevity.
It seems like I got it to work but it's erring out. I'm currently using the pydbgpproxy phyton script, version 7 from: http://code.activestate.com/komodo/remotedebugging/. I tried the version 8 script but it just errors. I also tried the pydbgpprox, version 6, but it still has the same exact issue.
IN SUMMARY: xDebug is running on the server, I can connect to it normally without proxy. With the proxy I can connect to it successfully to, but then running a script it encounters this werid error.
Does anyone know what this issue might be caused from?
Ok, here's the issue: I want to upload a DB I've got locally and I'm using in localhost, but, when I use:
PGPASSWORD=mypassword pg_dump -Fc --no-acl --no-owner -h localhost -U root app_db > app_db.dump
I always get:
pg_dump: [archiver (db)] connection to database "app_db" failed: could not connect to server: Connection refused
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" and accepting

I think the problem is that I'm writing localhost instead of my heroku app address, can anyone tell me how can I get the correct address?
You need to have postgresql installed and running
