We are using Amazon AWS Ubuntu machine for our server.
Rails 4.2.7 and Ruby 2.3
I have installed redis with these instructions (Redis)
and installed sidekiq with Sidekiq
I started redis, then starting sidekiq with just bundle exec sidekiq it give me error as running the jobs
FATAL: password authentication failed for user "ubuntu"
Not sure why this error. Any suggestions ?
Closing this thread as it has been fixed.
Changed the permissions for Redis from root level to user level.
And running sidekiq in production mode.

Hope everyone is keeping safe!
I have a Ruby on Rails application hosted on AWS Beanstalk. I am using CloudFormation template, to update any stack for e.g., Ruby version, Linux Platform upgrade etc.
I was trying to upgrade, Linux box to 2.11.7 and Ruby to 2.6.6 and then ElasticSearch to 7.4
I was doing these changes in CloudFormation YML template and then I ran aws cloudformation update-stack command to apply these changes.
While the changes took time, I accidentally clicked on Rebuild Environment from Web AWS Console as a result, all the previously configured settings like SQS, Load balancer etc., were replaced by new settings.
Now, whenever I am trying to execute the update-stack command, it fails with below errors:

I can confirm that I have Ruby-2.6.6 set. I am not sure from where it is picking up the old version of Ruby?
Is there any way I can fix this? OR forcefully apply template changes?
Any help on this would be highly appreciated.
[UPDATE]: When I try to connect to ElasticSearch from Rails console, I get:
Faraday::ConnectionFailed: Failed to open TCP connection to old-elasticsearch-host-name.es.amazonaws.com:80 (Hostname not known: old-elasticsearch-host-name.es.amazonaws.com)

The new URL of elasticsearch instance is different but it is still picking up the old URL from ELASTICSEARCH_HOST ENV variable.
Information from my CF template:
I can now provide info as per request. please tag me to see what I have in CF template
This was a config issue.
Whenever I was running aws update-stack command, it was going to s3 and pulling the zip (of the source code) code and in Gemfile of that zip code ruby version was set to 2.6.5.
So, I'd uploaded the fresh copy of the source code and then executed the update-stack command and it worked
I installed gitlab using these document.: https://docs.gitlab.com/ce/install/installation.html
When gitlab start, I get a message in the console: The GitLab Unicorn web server is not running.
It is unicorn.stderr.log:
I think it occur because of shell_secret, but I don't know how to solve it.
On installing gitlab, everything is fine.
But at final step of installation when I run command
$ sudo service gitlab start
it shows an error i.e., unicorn web server is not working but GitLab Sidekiq job dispatcher with pid 4182 is running properly.
When running the command
rails server
instead of the server running, I am getting the following output:
Why is the server not running?
It looks like you're not executing rails server inside a rails app directory.
Use rails new app_name and change directory into that app and run rails server again.
i have done an hadoop cluster installation with cloudera manager. After this installation impala status has become bad.
I have the following error for master node:
Web Server Status
and this one for nodes with imapala daemon:
Impala Daemon Ready Check, Web Server Status
looking into logs i have found some errors:
The health test result for IMPALAD_WEB_METRIC_COLLECTION has become bad: The Cloudera Manager Agent got an unexpected response from this role's web server.
looking into cloudera-scm-agent.log there are those errors:
1261 Monitor-HostMonitor throttling_logger ERROR (29 skipped) Failed to collect NTP metrics
i tryed to install NTP (sudo apt-get install ntp) but after this installation HDFS, HIVE, YARN and others services goes bad, removing that only impala goes bad.
MainThread agent ERROR Failed to connect to previous supervisor.
Another error is this:
Monitor-GenericMonitor throttling_logger ERROR Error fetching metrics at 'http://nodo-1:50075/jmx'
i tried looking all hostnames and seems correct...
so, what is this problem? how can i solve it?
I also had problem with NTP, the problem still existed after installing NTP , but when I done sudo service ntp restart the error was fixed
