mwget 多线程版本wget下载工具

本文介绍了一款多线程下载工具mwget,对比单线程wget,mwget在下载速度上有显著提升。通过实际测试,mwget在下载mongodb时,速度明显快于传统wget。文章还提供了mwget的安装步骤及使用方法。

linux运维在操作linux过程中,用得最多的linux下载工具想必一定是wget,没有看到哪一台服务器没装过wget的,或许有人使用ftp下载,也有人使用多线程的axel以及ProZilla,毫无疑问这两个工具都非常的出色,但是对于习惯使用wget的人来说显得不适应,于是老外便开发了多线程版本的wget工具mwget,m表示multi多线程的意思. 1. 安装mwget 官方地址:http://sourceforge.net/projects/kmphpfm/?source=dlp
# cd /usr/local/src/
# wget http://jaist.dl.sourceforge.net/project/kmphpfm/mwget/0.1/mwget_0.1.0.orig.tar.bz2
# tar -xjvf mwget_0.1.0.orig.tar.bz2
# cd mwget_0.1.0.orig
# ./configure
# make
# make install
configure过程中如果出现如下错误,请安装大于等于0.35版本的intltool
checking for intltool >= 0.35.0... ./configure: line 6824: intltool-update: command not found
 found
configure: error: Your intltool is too old.  You need intltool 0.35.0 or later.
# yum install intltool
2. wget vs mwget速度测试 以下使用下载2.4.5版本的mongodb来取样. 2.1 mwget速度测试
# mwget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.5.tgz

4. 总结 mwget虽然功能偏少,并且无法完全替代单线程版本的wget,但是对于我们基本只是用wget简单下载运维人员来说,mwget绝对是个完好的选择. 转载请注明出处:http://www.ttlsa.com/html/2371.html
