Sidekiq错误：无法连接到服务器：没有这样的文件或目录
我遇到了我的sidekiq，heroku，redistogo，rails 4配置问题。 我在heroku上有1个dyno和1个worker。 我只是使用worker来获取外部api的请求。
这是我在Heroku日志中得到的错误：
app[worker.1]: could not connect to server: No such file or directory app[worker.1]: connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? app[worker.1]: Is the server running locally and accepting 这是我的config/initializers/sidekiq.rb
if Rails.env.production? Sidekiq.configure_client do |config| config.redis = { url: ENV['REDISTOGO_URL'] } end Sidekiq.configure_server do |config| config.redis = { url: ENV['REDISTOGO_URL'] } Rails.application.config.after_initialize do Rails.logger.info("DB Connection Pool size for Sidekiq Server before disconnect is: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}") ActiveRecord::Base.connection_pool.disconnect! ActiveSupport.on_load(:active_record) do config = Rails.application.config.database_configuration[Rails.env] config['reaping_frequency'] = ENV['DATABASE_REAP_FREQ'] || 10 # seconds # config['pool'] = ENV['WORKER_DB_POOL_SIZE'] || Sidekiq.options[:concurrency] config['pool'] = 16 ActiveRecord::Base.establish_connection(config) Rails.logger.info("DB Connection Pool size for Sidekiq Server is now: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}") end end end end
这是我的Procfile
web: bundle exec puma -C config/puma.rb worker: bundle exec sidekiq -e production -C config/sidekiq.yml
这是我的config/sidekiq.yml
development: :concurrency: 5 production: :concurrency: 20 :queues: - default
这是我的config/initializers/redis.rb
uri = URI.parse(ENV["REDISTOGO_URL"]) REDIS = Redis.new(:url => uri)
这是我的config/puma.rb
workers Integer(ENV['WEB_CONCURRENCY'] || 2) threads_count = Integer(ENV['RAILS_MAX_THREADS'] || 1) threads threads_count, threads_count preload_app! rackup DefaultRackup port ENV['PORT'] || 3000 environment ENV['RACK_ENV'] || 'development' before_fork do puts "Puma master process about to fork. Closing existing Active record connections." ActiveRecord::Base.connection.disconnect! end on_worker_boot do ActiveRecord::Base.establish_connection end
根据你的Heroku日志，它给PostgreSQL服务器的错误而不是Sidekiq。
所以你需要先修复它。
