Top Stories imageMagick图片处理工具 March 14, 2026 Aman ImageMagick是一套Linux下的开源图形处理工具,针对几乎所有的图片格式提供比较全面的图片处理功能。不像windows下的photoshop,先要双击运行,然后打开图片,然后才能对图片进行处理,ImageMagick可以直接在命令行下运行,加上几个参数,就可以得到想要的图片了,而大批量的处理图片也比photoshop简单的多,写个shell多循环几次就可以了。 假如我想给图片加个框,转一下,再加个阴影,输入以下的命令就可以了: convert -size 400x180 hatching.jpg -thumbnail '200x90>' -bordercolor white -border 6 -bordercolor grey60 -border 1 -background none -rotate 6…
Top Stories bind dlz – 分布式系统的请求分发工具 March 14, 2026 Aman bind dlz全称是bind dynamic loadable zones,是基于bind的提供的一个组件,作用看名字就知道了,支持动态域加载支持。 bind已经有很久的历史,目前是搭建DNS服务器的首选。对于一般网站来说,一个标准的bind已经完全可以完成所有dns解决的工作,但在海量域名数量的情况下,bind也确实存在着一些问题: 1、域名解析信息全部存储在文本文件中,这非常容易导致由于编辑出错导致的域名解析出错。 2、bind运行时将全部的解析信息放在内存里,如果数量巨大将可能出现内存不足的情况,同时解析信息重新加载时所耗费的时间也非常值得考虑,由于加载时间较长,所以基本可以不考虑动态的进行域名的调整。 dlz就是为了解决这个问题而针对bind开发的组件,可以将域名解析信息放在数据库中,从而避免域名信息变动时重新加载的时间,在变动后马上生效。 dlz支持多种数据存储形式,包括文件系统,Berkeley-DB,Postgre-SQL,MySQL,ODBC,LDAP等等。性能的比较在这里。 bind dlz这种提供动态的域名调整,并且仍然可以提供高性能的dns解析服务的特点可以应用于提供二级或三级域名服务的分布式系统的前端,对不同的域名解析到所在服务器组上,从而实现可扩展的系统架构。
