Despite much effort trying all solutions posted on stackoverflow, I still cannot manage solving this.
The problem (Case 1):
$ sudo supervisorctl -c /app/vpn_bot/supervisord.conf
http://localhost:9001 refused connection
Case 2:
$ sudo supervisorctl -c /app/vpn_bot/supervisord.conf
unix:///tmp/supervisorctl.sock refused connection
Here is the relevant supervisord.conf file:
[supervisord]
# nodaemon=true
[supervisorctl]
# case 1: serverurl=http://127.0.0.1:9001
serverurl=unix:///tmp/supervisorctl.sock # case 2
[unix_http_server]
file=/tmp/supervisorctl.sock
[inet_http_server]
port=127.0.0.1:9001
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
I have made sure sudo supervisord -c /app/vpn_bot/supervisord.conf is running, and port 9001 is not used by any other process.
Any one can offer some help here?

I entered the etcd container:
kubectl -n kube-system exec -it etcd-k8scp -- sh
The I try to backup the container like explained in the K8s docs
ETCDCTL_API=3 etcdctl --endpoints $ENDPOINT snapshot save snapshotdb
I get this error:
Error: unknown command "save" for "etcdctl"
What's wrong with my command?
I forgot to set $ENDPOINT.
If it is empty, then etcdctl gets this:
ETCDCTL_API=3 etcdctl --endpoints snapshot save snapshotdb
etcdctl thinks I want to address the endpoint called "snapshot" and execute the command "save"
:-)

I am to re-install postgresql as something I was not able to log in anymore(lost password). However, every time I am trying to kill the process on corresponding port (5432), the PID changes and the port is still does not get freed. I am getting frustrated, this is taking over 2 weeks now.
Here is what I am doung:
#find the PID on 5432
sudo lsof -i: 5432 # this gives me a line where I can identify the process ID
sudo kill -9 <PID> # I use the PID given by the previous function
The last command gives a prompt asking me whether I want postgres to accept incoming network connections. Whichever option I choose (deny or allow) leads to the same thing. When I try to start postgres is still tells me that port 5432 is busy and indeed it is busy. When I re-use the first command above I notice that postgres is still there and the PID has changed.
I sorted the problem. I had other instances of postgres(9.5 I believe running in the background). I found it in my Library. now that port is completely free.

I want to change my Postgres database username and password for the running pod.
I am able to change the password but how to change the username?
Connect to the pod:
kubectl exec -it <pod-name> bash
Run psql
# psql
psql>
Create the user:
CREATE USER name CREATEUSER;
ALTER USER name WITH PASSWORD 'your-password';
or simply run createuser from the pod:
# createuser --aduser name

I want to install mango DB in FreeBSD sever.In mango DB documents they are not telling about UNIX servers.
Please let me know the step by step guide.
Here's a link for that:
https://www.digitalocean.com/community/tutorials/how-to-install-mongodb-on-freebsd-10-1
But since links-alone is poor stackoverflow.com protocol, this is essence of what you need to do when logged in on that server:
sudo pkg update -f
sudo pkg install mongodb
sudo service mongod start
P.S. mongo, not mango.

I'm using Linux CentOS 5.4, I installed MongoDB now it's availabled as a Daemon and Service
When I execute service mongod start is says : [OK] --> in green as if the service started but when I try to connect to it I find it not working.
but when I try to run "mongod" from the shell normally it starts but if I closed the shell connections it stops.
how do I add it to the start up of the OS ? or how do I run it in the background ?
add /usr/bin/mongod to /etc/rc.local this will make it start with the startup scripts
I think you need to create basic init scripts to start Mongodb as daemon and create mongodb user. Detailed information can be found here: Mongo DB installation
