I have a strange problem. For some reason, ansible-galaxy command is not using my defined http proxy.
I am getting the following error:
sudo ansible-galaxy collection install community.docker
[sudo] password for <user>:
[WARNING]: - collection was NOT installed successfully: Failed to get data from the API server (https://galaxy.ansible.com/api/): Failed to connect to galaxy.ansible.com at port 443: [Errno 110]
Connection timed out
ERROR! - you can use --ignore-errors to skip failed roles and finish processing the list.
I defined multiple variables to make sure proxy is triggered.
http_proxy
https_proxy
HTTP_PROXY
HTTPS_PROXY
Through wireshark analysis I can see that command ansible-galaxy collection install community.docker is trying to reach galaxy.ansible.com directly (resolving to: 104.206.0.234). It should go via proxy.
I also analyzed curl google.com and I can confirm that this traffic is going through http proxy, so the proxy is 100% working correctly.

Im attempting to setup keystone identity service on virtualized Ubuntu 20.4 via Windows Hyper-V on Windows 10.
I followed the instructions on: https://docs.openstack.org/keystone/pike/install/index-ubuntu.html very carefully & attempted this 4 times from scratch with a new VM.
However, all calls to OpenStack web service API either via curl, or command line result in some type of 404 Error.
Here my detailed steps (not including VM setup):
Install & Setup MySQL for keystone:
apt install keystone :
configure keystone:
fernet setup:
Bootstrap keystone:
Apache2 setup:
In /etc/apache2/apache2.conf
Set ServerName controller
source confif file
check port 5000.
set local host name resolution:
Start apache. service apache2 restart
Here is the issue:
Attempt # 1 - Using curl to call keystone API (404):
Attempt # 2 - Using openstack command line tool, again (404):
Troubleshooting:
Keystone logs look good with no error:
Furthermore, apache2 is running as I can see default server page:
So why cant keystone API be reached?
Appreciated
export these variables and test again
export OS_AUTH_VERSION=3
export OS_ENDPOINT_TYPE=internalURL
export OS_INTERFACE=internalURL
export OS_AUTH_TYPE=password
export OS_TENANT_NAME=admin
export OS_NO_CACHE=1
check your wsgi and apache2 vhost config too, to make sure apache will redircet it correctly
would you please check if libapache2-mod-WSGI is installed as it is mentioned in the documentation

i am begginer user of vps, i have a reactJS app, and i wnat to deploy it on my ubuntu 18 vps with nginx.
I have followed the stpes of this tutorial Deploying create-react-app with Nginx and Ubuntu
i had already check all the steps, but when i put the command
sudo service nginx start
the system show's me, the next error message:
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
and when i put "journalctl -xe" shows me this:
nginx, error
ngnix, error
please help me friends
Look in your log file on messages before the error "Failed to startup nginx"
You will see the reason of problem.
bind() to 0.0.0.0:80 failed (98: Address already in use)
Looks like port 80 on your vps server is already in use by some application.
Port 80 used for HTTP services.
So most likely you already have run Apache HTTP server, or some other.
use this command to see what application use it
sudo netstat -tulpn | grep ":80"
If you see apache
tcp6 0 0 :::80 :::* LISTEN 349/apache2
then you can stop apache
# apache service name also can be httpd (use right command)
# sudo service httpd stop
sudo service apache stop
and run nginx
sudo service nginx start
But you should be sure that you don't use apache for another website.
I am using 5 cloud-based VMs to install DC/OS
1 mesos master
3 mesos agent
1 launching VM
I have installed Docker on my launching VM and start installing DC/OS. It is running successfully during install_prereqs stage without any errors. But it's failing during preflight with below errors for each of my VM system.
STDERR:
Connection to 129.114.18.235 closed.
STDOUT:

Do I need to install all the required software into my master and agents VMS? Please guide.
We have a similar setup but using straight vm's. We found docker needs to be running on all nodes, including masters, before running the install. Also, make sure you look at: /etc/sysconfig/docker-storageand have: DOCKER_STORAGE_OPTIONS= -s overlayset in the file on all nodes.
I don't believe this is the production setup but should get you running. You also may want to check the privilege of the user executing the install on the remote nodes, does it have permission to see/run systemctl?
I had the same error with the DC/OS web installer in version 1.9
I solved the error after double-checking the bootstraps machines's private key in the web form. To create the key, log into the bootstrap machine and run:
$ ssh-keygen -t rsa
$ for i in `cat dcos-ips.txt`; do ssh-copy-id root#$i; done
$ cat ~/.ssh/id_rsa
I got a Mesosphere-EE, and install on fedora 23 server (kernel 4.4)with:
$bash dcos_generate_config.ee.sh --web –v
then output:
Running mesosphere/dcos-genconf docker with BUILD_DIR set to/home/mesos-ee/genconf
Usage of loopback devices is strongly discouraged for production use.Either use `--storage-opt dm.thinpooldev` or use `--storage-opt
dm.no_warn_on_loop_devices=true` to suppress this warning.

Disable Selinux!
Configure SELINUX=disabled in the /etc/selinux/config file and then reboot!
Be ensure the selinux is disabled by the command getenforce.
$ getenforce
Disabled
zhe.
Correctly installing the enterprise edition depends on the correct system prerequisites. Anyway I suppose you're still on the bootstrap node so I will give you some path to succed in your current task.
Run the script as root or as a user issuing sudo dcos_generate_config.ee.sh
The script will also generate the config file automatically; if you want to use your own configuration file then create a folder named genconf and put it inside before running the script. You should changes the values inside <> with your specific configuration. If you need more help for your specific case send me an email to infofs2 at gmail.com
I am new to mongoDB and i am trying to get it configured and running on my Ubuntu server. When i go and enter this command in my terminal
sudo service mongod start
I get the following output
start: Job is already running: mongod
So, when i try to enter the shell with
mongo
I get the following output
2015-02-24T14:54:39.557-0800 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2015-02-24T14:54:39.559-0800 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
I know I'm not working locally so I heard over to the mongod.conf file and change the following
port = 5000
# Listen to local interface only. Comment out to listen on all interfaces.
bind_ip = 10.0.1.51
Where bind_ip is now my ubuntu server and the port is 5000 as shown, so now i restart the service with
sudo service mongod restart
and outsputs
mongod start/running, process 1755
And now I try to renter back into shell with
mongo
and i still get the same error messages
MongoDB shell version: 2.6.7
connecting to: test
2015-02-24T15:01:26.229-0800 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused

exception: connect failed
Can someone help me out with this issue? I've been going through the forums and nothing appears to be working. Thanks.
If anyone is having trouble, i looked into mongod --help and found the following solutions
mongod --smallfiles
or
mongod --nojournal
hope this helps anyone.
