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.
mwget
官方地址：/projects/kmphpfm/?source=dlp
代码如下:
# cd /usr/local/src/
# wget /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
代码如下:
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速度测试
以下使用下载2.4.5版本的mongodb来取样.

Axel
运维工作中，常常需要下载文件，因为网站下载速度限制或者网络等原因导致下载让人无法忍受，前面有介绍多线程wget工具mwget，提速不少，而且使用很简单。axel使用的人更多，不仅仅安装方法简单，命令更简单。往下看。
安装Axel
RPM安装Axel(方法一)
下载地址：/axel/
如图，选择适合你服务器的RPM
复制代码
代码如下:
root@ttlsa # wget /axel/axel-2.4-1.el6.rf.x86_64.rpm
root@ttlsa # rpm -ivh axel-2.4-1.el6.rf.x86_64.rpm
Preparing... ########################################### [100%]
1:axel ########################################### [100%]
yum安装Axel(方法二)
复制代码
代码如下:
root@ttlsa # yum install axel
apt-get安装Axel
如果你是Ubuntu系统
代码如下:
root@ttlsa # axel -h
Usage: axel [options] url1 [url2] [url...]
--max-speed=x -s x 最大速度 (字节/秒)
--num-connections=x -n x 最大连接数
--output=f -o f 指定文件名
--search[=x] -S [x] Search for mirrors and download from x servers
--header=x -H x 添加header
--user-agent=x -U x 设置用户代理
--no-proxy -N 不使用任何代理
--quiet -q Leave stdout alone
--verbose -v 显示更多状态信息
--alternate -a 显示简单进度条
--help -h 帮助
--version -V 版本信息
axel使用实例
下载centos
代码如下:
root@ttlsa # axel /centos/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso

下载运维生存时间某图片
复制代码
代码如下:
root@ttlsa # axel /wp-content/uploads/2014/04/zabbix-adduser-01.jpg

简单进度条
默认情况下，整个屏幕都是进度条，加上-a参数，进度条类似wget。
复制代码
代码如下:
root@ttlsa # axel -a /centos/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso
Initializing download: /centos/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso
File size: 4467982336 bytes
Opening output file CentOS-6.5-x86_64-bin-DVD1.iso
Starting download
[ 1%] [0 1 2 3 ] [ 3.2MB/s] [21:47]
下载限速
ttlsa的网站带宽有限制，我要保证下载的同时又不影响用户的访问，例如限制为1MB/s的下载速度，如下可以看到速度基本保证在1MB以内。
复制代码
代码如下:
root@ttlsa # axel -s 1024000 /centos/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso
Initializing download: /centos/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso
File size: 4467982336 bytes
Opening output file CentOS-6.5-x86_64-bin-DVD1.iso

最后
完成，方法很简单，功能很简单。运维生存时间的服务器以及安装了axel，你的安装了吗?
