Redmine 数据库连接错误

/********************************************************************
 *                    Redmine 数据库连接错误
 * 说明：
 *     OpenMediaVault上的Redmine出现连接错误，目前不知道是我自己不小心
 * 把mysql的密码修改了，还是因为被攻击了，先记录一下。

java项目使用mvn打包时，出现数据库连接错误

原因: maven在install的时候会默认去执行test包下的test示例,导致打包失败,只需要把测试注释掉就可以了包括类上的注解,或者在install的时候跳过测试,install -Dmaven.test.skip=true 重新输入:mvn install -Dmaven.test.skip=true 打包成功! 原文地址:https://www.cnblogs.com/mufengforward/p/10408541.html

数据库连接失败时，如何捕捉错误，避免弹出错误提示，以便下次自动重新连接

主要是要避免人工介入.一旦弹出错误提示,如果没有人工介入把它关掉,则程序会一直停在那里,无法自动重新连接. 在连接的时候虽然加入了try....except保护,但还是无法避免在操作数据库中数据时网络连接突然断掉或数据库服务被关闭时弹出错误提示. 曾经看到过可以在Application的某个事件中进行处理,但现在检索不到 LZ说的那个事件是Applicataion.OnException,程序所有错误都会触发这个事件 一个系统和数据库连接的代码可能有很多,又存在于不同的单元 每个open/exc

从头开始安装redmine项目管理软件

redmine是采用ruby语言基于rails架构写的一款稳定高性能项目管理服务器,这里记录一下完整的安装过程. 注意:所有的操作都在普通用户中进行,不要使用root用户,如果需要高级别权限可以sudo命令执行. 第一步:安装RVM软件,参考链接:http://www.rvm.io/ RVM称作Ruby Version Management,用于管理RUBY的版本功能,可以实现自动安装.可以输入rvm回车查看支持的命令,rvm list known 可以查看当前支持的版本.[[email pro
