环境：

bitnami-redmine-2.5.1-1-linux-x64-installer.run

用bitnami安装完redmine以后，有是否忘记了用户名和密码。但是又没有配置邮件服务器，无法找回密码。

只能去服务器更改了。更改步骤如下：

1. 修改 安装目录/redmin/apps/redmine/htdocs/config/database.yml，更对对应的用户名，密码，数据库地址，端口号

production:

adapter: mysql2

database: bitnami_redmine

host: 127.0.0.1

username: root

password: ""

port: 3307

encoding: utf8

socket: /home/hyadmin/redmin/mysql/tmp/mysql.sock

development:

adapter: mysql2

database: redmine_development

host: localhost

username: root

password: ""

encoding: utf8

# 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: redmine_test

host: localhost

username: root

password: ""

encoding: utf8

2. 进入如下目录

cd 安装目录/redmin/apps/redmine/htdocs/script

3. 执行如下命令，进入ruby

./rails console production

4. 取得你要修改的用户对象(ruby>代表进入ruby环境)

ruby> admin_user = User.find_by_login('你要改的用户名')

5.修改admin用户对象密码

ruby> admin_user.password = '你的密码'

注: 这个密码不能太短，否则报错。

6.保存admin用户对象信息

ruby> admin_user.save!

7.退出ruby环境

ruby> quit

这样应该就可以用yourpassword这个新密码登录系统了
