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
