ruby-on-rails-4 - Rails 4.2:sidekiq 无法连接到 Redis(Errno::ECONNREFUSED)，由 foreman 启动

转载作者：可可西里更新时间：2023-11-01 11:36:45

在本地主机上的开发模式下(OS X°我开始使用

foreman start

我的 Procfile 是: postgresql: postgres -D 供应商/postgresql redis: redis 服务器供应商/redis/db/redis.conf redis-slave:redis-server vendor/redis-slave/db/redis.conf sidekiq: sidekiq -C config/sidekiq.yml -q devise,1 -q default -q mailers sidekiq_web: thin -R sidekiq.ru start -p 9292 邮件:mailcatcher -f 网络:bundle exec unicorn -p 3001 -c ./config/unicorn.rb rails: bundle exec rails s unicorn

一切正常，但 sidekiq 无法连接到正在运行的 Redis 实例，因此它退出并返回代码但是，如果我在不同的窗口中启动每个进程，它运行良好......我的工头脚本可能有什么问题？

最佳答案

尝试使用“127.0.0.1”或“::1”代替“localhost”。 IPv6 与 IPv4 有时会很棘手。
