Rails 7.0.8.1生产环境Sidekiq连接Redis版本不匹配问题

问题描述 #

生产环境部署的Rails 7.0.8.1应用，运行在Ubuntu 22.04服务器上，已安装Redis 7.2.5，但启动Sidekiq时，系统提示连接的是Redis 6.0.16，不符合Sidekiq 7.1.1要求的Redis 6.2.0及以上版本，导致启动失败。

环境配置 #

Systemd服务文件（/etc/systemd/system/sidekiq.service） #

[Unit]
Description=Sidekiq
After=syslog.target network.target

[Service]
Type=simple
WorkingDirectory=/home/deploy/lipepay/current
ExecStart=/home/deploy/start_sidekiq.sh
User=deploy
Group=deploy
UMask=0002
RestartSec=15
Restart=always
Environment=REDIS_URL=redis://127.0.0.1:6379/0

[Install]
WantedBy=multi-user.target

启动脚本（/home/deploy/start_sidekiq.sh） #

#!/bin/bash
# File: /home/deploy/start_sidekiq.sh

# Load Ruby version manager environment
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

# Set REDIS_URL
export REDIS_URL=redis://127.0.0.1:6379/0

# Navigate to application directory
cd /home/deploy/lipepay/current

# Start Sidekiq
exec /home/deploy/.rbenv/shims/bundle exec sidekiq -e production

Sidekiq初始化器（config/initializers/sidekiq.rb） #

require 'sidekiq/cron'

if Rails.env.production?
  schedule_file = "config/schedule.yml"
  
  if File.exist?(schedule_file) && Sidekiq.server?
    yaml_jobs = YAML.load_file(schedule_file)
    existing_jobs = Sidekiq::Cron::Job.all.map(&:name)
    
    yaml_jobs.each do |name, details|
      unless existing_jobs.include?(name)
        Sidekiq::Cron::Job.create(name: name, cron: details['cron'], class: details['class'])
      end
    end
  end

  Sidekiq.configure_server do |config|
    config.redis = { url: ENV['REDIS_URL'] }
  end

  Sidekiq.configure_client do |config|
    config.redis = { url: ENV['REDIS_URL'] }
  end
end

错误日志 #

journalctl -u sidekiq输出：

Jun 26 17:34:27 ubuntu-2gb-hil-1 start_sidekiq.sh[348225]: You are connecting to Redis 6.0.16, Sidekiq requires Redis 6.2.0 or greater

已采取的步骤 #

• 检查Redis版本：

  redis-server --version
  # Output: Redis server v=7.2.5 sha=00000000:0 malloc=jemalloc-5.3.0 bits=64 build=d2f534f69a26fea
  

• 在Rails控制台验证Redis连接版本：

  redis = Redis.new(url: ENV['REDIS_URL'])
  puts redis.info["redis_version"]
  # Output: 7.2.5
  

• 检查Gemfile.lock中的Sidekiq依赖：

  grep sidekiq Gemfile.lock
  # Output:
  # sidekiq (7.1.1)
  # sidekiq-cron (1.10.1)
  

• 查看Sidekiq服务状态：
