我的应用程序正在使用DelayedJob,但速度很慢所以我决定切换到Sidekiq。
到目前为止,它还没有与Sidekiq一起进行测试或开发。 (当然,我还没有尝试过使用Sidekiq进行制作。)
从DelayedJob搬到Sidekiq时,我开始更新我的Profile
:
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
# worker: bundle exec rake jobs:work
before_fork do |server, worker|
@sidekiq_pid ||= spawn("bundle exec sidekiq -c 2")
end
我假设这意味着我不必在bundle exec sidekiq
之前输入foreman start
,对吧?当我运行我的测试时,这应该启动sidekiq,对吗?
但是在我的测试中,我的应用程序中表达为@instance.delay.method
的所有内容(与DelayedJob和Sidekiq一起使用)都无效。
因此,为了尝试处理正在发生的事情,我将以下内容添加到routes.rb
:
Testivate::Application.routes.draw do
require 'sidekiq/web'
mount Sidekiq::Web, at: "/sidekiq"
但是,当我重新开始访问localhost:3000/sidekiq
时,我只看到:
No route matches [GET] "/sidekiq"
Routes
Routes match in priority from top to bottom
Helper HTTP Verb Path Controller#Action
Path / Url
sidekiq_web_path /sidekiq Sidekiq::Web
BTW,redis似乎在本地自动运行:
$ redis-cli ping
PONG
我的捆绑gemfile
包括:
ruby "2.0.0"
gem "rails", "4.0.2"
gem 'sinatra', require: false
gem 'slim'
gem "sidekiq"
gem "autoscaler"
我没有对unicorn.rb
进行任何更改:
# config/unicorn.rb
worker_processes 3
timeout 360
preload_app true
before_fork do |server, worker|
Signal.trap 'TERM' do
puts 'Unicorn master intercepting TERM and sending myself QUIT instead'
Process.kill 'QUIT', Process.pid
end
defined?(ActiveRecord::Base) and
ActiveRecord::Base.connection.disconnect!
end
after_fork do |server, worker|
Signal.trap 'TERM' do
puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to sent QUIT'
end
defined?(ActiveRecord::Base) and
ActiveRecord::Base.establish_connection
end
答案 0 :(得分:0)
我自己从DJ搬到了Sidekiq。虽然我的配置中没有看到任何明显的东西,但我会分享我的设置。关于如何配置Sidekiq的一些建议。希望这会有所帮助。
对于initializers / redis.rb,支持local和heroku envs:
module MyRedis
class << self
def redis
@redis ||= Redis.new(url: (ENV['REDISTOGO_URL'] || 'redis://127.0.0.1:6379'))
end
##
# test for avail
#
def sidekiq?
begin
redis_info = Sidekiq.redis { |conn| conn.info }
true
rescue
false
end
end
end
end
对于initilizers / sidekiq.rb(考虑参数化size
)
Sidekiq.configure_server do |config|
config.redis = { :url => MyRedis.redis[:url], :namespace => 'sidekiq', :size => 4 }
end
Sidekiq.configure_client do |config|
config.redis = { :url => MyRedis.redis[:url], :namespace => 'sidekiq', :size => 1 }
end
典型的config / sidekiq.yml:
:verbose: false
:concurrency: 25
:queues:
- [often, 7]
- [default, 5]
- [seldom, 3]
然后在你的Procfile中,sidekiq.yml:
web: bundle exec unicorn -p $PORT -E $RAILS_ENV -c ./config/unicorn.rb
worker: bundle exec sidekiq -C config/sidekiq.yml -e $RAILS_ENV
最后,我对config / unicorn.rb所做的唯一更改是在分叉时处理redis连接:
...
before_fork do |server, worker|
if defined?(MyRedis.redis)
MyRedis.redis.quit
Rails.logger.info('Disconnected from Redis')
end
...
after_fork do |server, worker|
if defined?(MyRedis.redis)
MyRedis.redis.client.reconnect
Rails.logger.info('Connected to Redis')
end
