Optimize linux download source

Step one:

(1) under the condition of ensuring that the host can connect to the network normally, configure the host DNS and perform related resolution, ping www.baidu.com

PING www.a.shifen.com (39.156.66.14) 56 (84) bytes of data.

64 bytes from 39.156.66.14 (39.156.66.14): icmp_seq=1 ttl=128 time=6.03 ms

64 bytes from 39.156.66.14 (39.156.66.14): icmp_seq=2 ttl=128 time=6.16 ms

64 bytes from 39.156.66.14 (39.156.66.14): icmp_seq=3 ttl=128 time=6.13 ms

Step 2:

In China, I choose Aliyun software website.

Mirrors.aliyun.com

(1) the update command is as follows:

Centos7:

Curl-o / etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

Note: because there is no wget command in Cetos7 by default, select curl

(2) Software developed by developers:

Normative verification: base warehouse requirements

Epel warehouse requires Extra Packages for Enterprise Linux (EPEL)

With the new epel warehouse: curl-o / etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

Install related software: yum install-y vim tree nc nmap dos2unix wget lrzsz bash-completion net-tools
