linux運(yùn)維在操作linux過(guò)程中,用得最多的linux下載工具想必一定是wget,沒(méi)有看到哪一臺(tái)服務(wù)器沒(méi)裝過(guò)wget的,或許有人使用ftp下載，也有人使用多線程的axel以及ProZilla,毫無(wú)疑問(wèn)這兩個(gè)工具都非常的出色,但是對(duì)于習(xí)慣使用wget的人來(lái)說(shuō)顯得不適應(yīng),于是老外便開(kāi)發(fā)了多線程版本的wget工具mwget,m表示multi多線程的意思.
mwget
官方地址：?source=dlp
代碼如下:
# cd /usr/local/src/
# wget
# tar -xjvf mwget_0.1.0.orig.tar.bz2
# cd mwget_0.1.0.orig
# ./configure
# make
# make install
configure過(guò)程中如果出現(xiàn)如下錯(cuò)誤，請(qǐng)安裝大于等于0.35版本的intltool
代碼如下:
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
wget vs mwget速度測(cè)試
以下使用下載2.4.5版本的mongodb來(lái)取樣.

Axel
運(yùn)維工作中，常常需要下載文件，因?yàn)榫W(wǎng)站下載速度限制或者網(wǎng)絡(luò)等原因?qū)е孪螺d讓人無(wú)法忍受，前面有介紹多線程wget工具mwget，提速不少，而且使用很簡(jiǎn)單。axel使用的人更多，不僅僅安裝方法簡(jiǎn)單，命令更簡(jiǎn)單。往下看。
安裝Axel
RPM安裝Axel(方法一)
下載地址：
如圖，選擇適合你服務(wù)器的RPM
復(fù)制代碼
代碼如下:
root@ttlsa # wget
root@ttlsa # rpm -ivh axel-2.4-1.el6.rf.x86_64.rpm
Preparing... ########################################### [100%]

yum安裝Axel(方法二)
復(fù)制代碼
代碼如下:
root@ttlsa # yum install axel
apt-get安裝Axel
如果你是Ubuntu系統(tǒng)
代碼如下:
root@ttlsa # axel -h
Usage: axel [options] url1 [url2] [url...]
--max-speed=x -s x 最大速度 (字節(jié)/秒)
