How to download files in centos

If we want to download a file, we can do it through the wget command.

First check whether wget is installed on the CentOS7 system:

[root@test redis]# rpm -qa|grep wget

If it is installed, it will prompt the currently installed version:

wget-1.14-15.el7_4.1.x86_64

If it is not installed, you can install it through the following command:

yum install -y wget

The syntax format for downloading files is: wget http://wwww.xxxxx. This command will download to the default download directory.

If we want to download to a specified directory, we can use the -P parameter to achieve this:

Command format: wget -P /Directory file download address where the file is saved

-P is followed by the directory where you need to save the file, such as /home/tmp/download, and the last parameter is the URL address of the network file you actually want to download. For example, the following command downloads the 6.4 version of elasticsearch. tar package to the /home/tmp/download directory:

[root@test redis]# wget -P /home/tmp/download https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.2.tar.gz
