This article mainly introduces "introduction to the usage of multithreaded download tools MWget and Axel under Linux". In daily operation, I believe that many people have doubts about the usage of multithreaded download tools MWget and Axel under Linux. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "introduction to the usage of MWget and Axel under Linux". Next, please follow the editor to study!

Linux operation and maintenance staff in the process of operating linux, the most frequently used linux download tool must be wget, did not see which server did not install wget, perhaps someone used ftp to download There are also people who use multithreaded axel and ProZilla. There is no doubt that these two tools are very good, but they are not suitable for people who are used to using wget, so foreigners developed a multithreaded version of the wget tool mwget,m to express the meaning of multi multithreading.

Mwget

Official address: http://sourceforge.net/projects/kmphpfm/?source=dlp

The code is as follows:

# 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

If the following error occurs during configure, please install intltool greater than or equal to version 0.35

The code is as follows:

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 speed test

The following samples are taken using the download version 2.4.5 of mongodb.

Axel

In the work of operation and maintenance, you often need to download files, because of the download speed limit of the website or the network and other reasons, the download is unbearable. Mwget, a multi-threaded wget tool, is introduced earlier, which is very fast and easy to use. Axel uses more people, not only the installation method is simple, but also the command is simpler. Look down.

Install Axel

RPM installs Axel (method 1)

Download address: http://pkgs.repoforge.org/axel/

As shown in the figure, select the RPM that is suitable for your server

The code is as follows:

Root@ttlsa # wget http://pkgs.repoforge.org/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 installs Axel (method 2)

The code is as follows:

Root@ttlsa # yum install axel

Apt-get install Axel

If you are a Ubuntu system

The code is as follows:

Root@ttlsa # axel-h

Usage: axel [options] url1 [url2] [url...]

-- max-speed=x-s x maximum speed (bytes / second)

-num-connections=x-n x maximum number of connections

-- output=f-o f specifies the file name

-- search [= x]-S [x] Search for mirrors and download from x servers

-- header=x-H x add header

-- user-agent=x-U x set up user agent

-- no-proxy-N does not use any agents

-- quiet-q Leave stdout alone

-- verbose-v displays more status information

-alternate-a displays a simple progress bar

-- help-h help

-- version-V version information

Download speed limit

The bandwidth of ttlsa's website is limited. I want to make sure that the download does not affect the access of users, such as the download speed of 1MB/s. As shown below, the speed is basically guaranteed within 1MB.

The code is as follows:

Root@ttlsa # axel-s 1024000 http://mirrors.btte.net/centos/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso

Complete, the method is very simple, the function is very simple. Operation and maintenance time of the server and installed axel, do you have the installation?
