CentOS uses commands to set proxy

CentOS uses commands to set proxy

Set Global Proxy as follows:

1. Set related environment variables in the profile file

# Vi/etc/profile

Http_proxy = http: // 192.168.20.20: 3128 # specify the proxy server addresses used by http, https, and ftp respectively.

Export http_proxy

2. source/etc/profile takes effect.

After modification, log out and log on again.

For the yum proxy, you must also set the/etc/yum. conf file and add the following code:
Proxy = http: // username: password @ yourproxy: 8080/
# If there is no password restriction, use the following method:
# Proxy = http: /yourproxy: 8080/

In this way, the yum operation passes the proxy.
