最近技安不再带自己的mac book来公司工作了，公司多出来一个台式机，重庆网站发开，配置还挺高。于是乎就拿过来用了。

装上了Ubuntu14.04 LTS版，正常的开发工具如vagrant，vitualbox，sublime text，QQ，搜狗输入法等后，折腾了一番，终于把开发环境搭建好了！

navivat由于下载的官方版本，有30天的使用期限限制。网上也有很多的“破解”时间限制的方法。技安很早之前也都使用过，唯一不爽的就是，每次删除~/.navicat文件夹的时候，保存在navicat里面的数据库链接都会丢失了。

最近技安研究了一番，发现navicat是通过user.reg文件来判断软件是否过期了。于是想，保留一个没有日期记录的user.reg文件，每次开机的时候把原先的user.reg文件删掉，然后用我们保留的文件拷贝过去不就可以永久使用了么。

约定环境：

navicat配置路径：/home/andy/.navicat

原始user.reg文件：/home/andy/.navicat/user.reg

备份的文件：/home/andy/.navicat/user_backup.reg

1、安装好navicat之后，第一次正常打开，然后添加好数据库链接信息。

用于生成原始user.reg文件。把生成好的原始user.reg文件打开，去掉每个中括号后面的时间戳

如下图所示，点击图片可以查看大图

仅仅保留部分关于编码和字体相关的设置即可，如下：
