ruby-on-rails - Rails 每当 rake 中止！PG::ConnectionBad: fe

问题描述

我正在使用 Rails 的Whenever gem 来运行 rake 任务，检查 Postgres 数据库中的条目更新。在 SSH 进入服务器时运行 rake 文件可以正常工作，但使用 cron 作业时它不会运行并显示错误消息。

rake aborted! PG::ConnectionBad: fe_sendauth: no password supplied

我的设置如下：

数据库.yml

default: &default
   adapter: postgresql
   host: localhost
   pool: 5
   encoding: utf8
   timeout: 5000
   username: username
   password: password

 development:
   <<: *default
   database: development
   password: password

 test:
   <<: *default
   database: test

 production:
  <<: *default
  database: production
  password: password

脚本.rake

namespace :user do
  desc "TODO"
  task update_subscription: :environment do
    puts "--- Starting user subscription check at #{DateTime.now} ---"
    User.find_each do | user |
      if user.refresh_date.past?
        user.refresh_date = Date.today + 1.month
        puts "User #{user.id} subscription updated"
      end
    end
  end
end

日程安排.rb

every 1.day, :at => '00:01 am' do
  rake "user:update_subscription"
end

crontab -l

1 0 * * *  /bin/bash -l -c 'cd /home/app/app && RAILS_ENV=production bundle exec rake user:update_subscription --silent >> log/cron_log.log 2>&1'

pg_hba.conf

local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                peer
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5

在日志文件中输出

--- Starting user subscription check at 2018-11-23T10:20:05+00:00 ---
rake aborted!
PG::ConnectionBad: fe_sendauth: no password supplied
/home/app/app/lib/tasks/script.rake:5:in `block (2 
levels) in <top (required)>'

/home/app/.rbenv/versions/2.3.8/bin/bundle:22:in `<main>'
Tasks: TOP => user:update_subscription
(See full trace by running task with --trace)

如果我更改 md5 并且对等信任 pg_hba.conf 一切都会正常工作，但据我所知，这对生产环境中的安全性不利。
