无法在 vagrant 上运行 sidekiq

Question

我正在通过 Ruby on Rails 开发一个 Web 应用程序，我想用deliver_later 发送电子邮件。

在Gemfile、gem sidekiq 和config/initializer/sidekiq.rb 中，

redis_sec = { host: '127.0.0.1' }
Sidekiq.configure_client do |config|
  config.redis = { url: "redis://#{redis_sec[:host]}:6379", namespace: 'sidekiq' }
end
Sidekiq.configure_server do |config|
  config.redis = { url: "redis://#{redis_sec[:host]}:6379", namespace: 'sidekiq' }
end

最后，在config/sidekiq.yml，

:pidfile: ./tmp/pids/sidekiq.pid
:logfile: ./log/sidekiq.log

我在app/workers/worker_for_sidekiq.rb写了一个测试sidekiq队列：

class WorkerForSidekiq
  include Sidekiq::Worker
  sidekiq_options queue: :sidekiq
  def perform(text)
    sleep 5
    p text
  end
end

然后，bundle exec sidekiq -q sidekiq 在 vagrant 上运行 sidekiq 会报错：

ERR Syntax error, try CLIENT (LIST | KILL ip:port)

所以，我试试reids-cli 和CLIENT LIST：

redis 127.0.0.1:6379> CLIENT LIST
addr=127.0.0.1:49802 fd=5 idle=0 flags=N db=0 sub=0 psub=0 qbuf=0 obl=0 oll=0 events=r cmd=client

我完全遵循this Japanese blog 的指示。我搜索了一些关键字，例如“sidekiq 语法错误”、“sidekiq vagrant error”、“sidekiq virtualbox”和“sidekiq 客户端列表”，但没有找到有用的文章。

怎么了？ sidekiq 在 vagrant 上不可用吗？

Answer 1

查看堆栈跟踪，错误似乎源自this block：

with_reconnect(false) do
  establish_connection
  call [:auth, password] if password
  call [:select, db] if db != 0
  call [:client, :setname, @options[:id]] if @options[:id]
  @connector.check(self)
end

特别注意这一行：

call [:client, :setname, @options[:id]] if @options[:id]

CLIENT SETNAME 命令仅适用于 Redis 2.6.9。如果您尝试使用旧版本运行它，则会收到您所看到的错误消息。

解决方案是将 Redis 升级到至少 2.6.9。
