In Linux system proxy can be directly set up, but it does not support account password authentication. Therefore, we set up the proxy through the proxy tool proxychains, first installing proxychains4.When a pop-up occurs during the installation process, simply press Enter to confirm.
Installation command examples:
Debain：apt-get install proxychains4
Centos: yum install proxychains4
After installation,run following command to set proxychains4
vim /etc/proxychains.conf
Set proxies to 8.8.8.8 or directly look down on this line.
Then set the proxy in the proxy list in the form of proxy type, proxy host, proxy port, proxy user, and proxy pass.
Note that the proxy address needs to be filled in with an IP address. If you do not know the IP address, you can ping the proxy domain name to obtain the IP address.
Finally, you can use proxychains to proxy
