mysql - rails 应用程序在网络浏览器中显示访问被拒绝

Question

Access denied for user 'root'@'localhost' (using password: YES)

我设置了一个 mysql 没有密码的新环境，以及我是如何收到此错误的。我在哪里更改

'root'@'localhost' (using password: YES)

我的 database.yml 显示在下面我的数据库是 sample_app

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: mysql2
  database: db/development.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /tmp/mysql.sock

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql2
  database: db/test.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /tmp/mysql.sock

 production:
  adapter: mysql2
  database: db/production.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /var/run/mysqld/mysqld.sock

Answer 1

您不应该使用 root 连接到带有应用程序的数据库。创建一个新的用户/密码，其名称可识别它正用于特定的应用程序\任务，然后使用该名称代替 root。

为空密码添加这个 password:

production:
  adapter: mysql2
  database: db/production.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  password:
  socket: /var/run/mysqld/mysqld.sock

如果您仍然拒绝访问，则数据库表示用户\密码无效
