I want to run Resque workers on different servers, getting jobs from one Redis server. I know how to configure it in a Rails application, but the problem is I am using standalone Resque (https://github.com/dcestari/resque-standalone-sample) on every Server.
So my question is, how can I do this without installing a Rails application and is it possible?
Thank you!
You'll need to tell Resque where Redis lives:
Resque.configure do |config|
# Set the redis connection. Takes any of:
# String - a redis url string (e.g., 'redis://host:port')
# String - 'hostname:port[:db][/namespace]'
# Redis - a redis connection that will be namespaced :resque
# Redis::Namespace - a namespaced redis connection that will be used as-is
# Redis::Distributed - a distributed redis connection that will be used as-is
# Hash - a redis connection hash (e.g. {:host => 'localhost', :port => 6379, :db => 0})
config.redis = 'redis://someserverip:port:db/namespace'
end

This is my 3rd day in a row trying to start a new app using Postgresql w/ Ruby on rails with wsl ubuntu.....(i'm on windows)
I'm a beginner. I've learned the basic syntax, but getting a practice app running on Postgres i just cant seem to do it. ill literally pay for help if someone can help me out.
Everytime i try to start the database i get
chronokross#DESKTOP-V7DS5HD:/mnt/c/code/nathantest$ rake db:create
Database 'chrono_development' already exists
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Couldn't create 'chrono_test' database. Please check your configuration.
rake aborted!

I've followed millions of guides. I dont know how to connect postgresql on windows to my ubunix server ROR app.
my discord is ChronoKross#1560.
They say to edit my databse yml file. This is how i did it

PLEASE PLEASE I BEG FOR HELP. I've been studying 8hrs a day but this is a HUGE road block, i need someone to tell me what to do in noob terms or screenshare with me.
again my discord is ChronoKross#1560
I'm using net-sftp which relies on the net-ssh gem.
I'm trying to connect to a remote log service via SFTP, and it requires IP whitelisting. All my current servers have dynamic IPs.
I'm trying to set up a static, secure, proxy server in Google Cloud. I don't really understand all the differences between all the types of proxying, but net-ssh appears to support...
socks4
socks5
'jump' proxy
I looked into setting up a socks5 proxy with Dante but it appears a bit overkill just to relay the SFTP connection through it, not to mention I think it sends passwords in plain text.
How would I go about proxying net-sftp through some server in the easiest way?
The easiest way would be to setup a Jump-host server that can reach the target servers and then connecting to the target server by letting the Jump-host server proxy your connection through.
SSH makes it trivially easy:
ssh -J user#jump-host myuser#target-host
In your .ssh/config you can do the following:
### First jump-host. Directly reachable
Host jump-host
HostName jum-phost.example.org
### Host to jump to via jump-host.example.org
Host target-host
HostName target-host.example.org
ProxyJump jump-host
This will allow you to use net-ssh as usual. If you dont want to change the config file then you will have to use 'net/ssh/proxy/jump':
require 'net/ssh/proxy/jump'
proxy = Net::SSH::Proxy::Jump.new('user#proxy')
Net::SSH.start('host', 'user', :proxy => proxy) do |ssh|
...
end
See this article for more info on Jump Hosts.
I need to make logging with logstash in Padrino project. I setup logstash on remote server and tried to integrate it with Padrino project, I found only one solution
logger = LogStashLogger.new(type: :udp, host: host, port: 5044) if RACK_ENV = 'staging'
but it can working only when use this code logger.debug message: 'test', foo: 'bar'
Can I make that all logs automatically will send to remote server?
Try this:
Padrino::Logger.logger = LogStashLogger.new(type: :udp, host: host, port: 5044)
I use this:
Padrino::Logger.logger = LogStashLogger.new(type: :udp, host: '172.16.x.x', port: 9999).extend(Padrino::Logger::Extensions)
I have a situation somewhat similar to "How to create a ssh tunnel in ruby and then connect to mysql server on the remote host."
From my local machine, I want to run a query against a production MySQL database host.
My local machine cannot directly connect to the database host. However, if I SSH to a gateway machine, I can run the MySQL client and connect to the database host.
I'm trying to figure out how to programmatically to run a query from my machine that is forwarded to the gateway machine, which forwards it to the database server, and have results returned. Basically I want to have LOCAL => GATEWAY => DB_HOST forwarding.
I have a hacky solution that runs ssh.exec and MySQL on the command line, shown below, but, I'm trying to find a way that does port forwarding twice.
I tried, but haven't been successful so far.
require 'rubygems'
require 'mysql2'
require 'net/ssh/gateway'
gateway = Net::SSH::Gateway.new(
$gateway_host, $gateway_user,:password => $gateway_pass)
# This works
ssh = gateway.ssh($db_host, $db_login_user)
data = ssh.exec!("mysql -u#{$db_user} -p#{$db_pass} #{$db_name} -e '#{$sql_query}'")
puts "#{data.class} is the class type"
puts data
# Want to do something like this with port forwarding
# client = Mysql2::Client.new(:host => $db_host,
# :username => $db_user,
# :password => $db_pass,
# :database => $db_name,
# :port => port)
# results = client.query($sql_query)
puts "end stuff"
ssh.close
Any suggestions?
Your diagram lays it out fairly well, you would need a tunnel from the Gateway to the Db_Host; and a second tunnel from your local machine to the gateway. The two tunnels would effectively connect your local machine to the db_host by way of the gateway.
Here's a reference specific to tunneling MySQL over SSH
Inspired by the RailsCast on HTTP Streaming, I've decided to turn it on on my server. However, the listen 3000 :tcp_nopush => false line that Ryan suggests adding to my unicorn.rb doesn't play well with Heroku (they don't let you specify a port). Is streaming supported on Heroku, and how do I turn it on?
Heroku tells your application what port to listen on via the environment variable PORT. Check for this environment variable in your unicorn.rb.
port = ENV["PORT"].to_i
listen port, :tcp_nopush => false
