Configure Proxy Server in Ubuntu

How to configure a proxy server in Ubuntu for Linux PCs and servers.

sudo vim  /etc/environment

export http_proxy="http://username:[email protected]:12345"
export https_proxy="http://username:[email protected]:12345"
export ftp_proxy="http://username:[email protected]:12345"
export HTTP_PROXY="http://username:[email protected]:12345"
export HTTPS_PROXY="http://username:[email protected]:12345"
export FTP_PROXY="http://username:[email protected]:12345"

By doing this, you can configure the proxy server.

To check the proxy server configuration, execute the following command:

env | grep -i proxy

Also, to remove the proxy server configuration, execute the following command:

unset http_proxy
unset https_proxy
unset ftp_proxy
unset HTTP_PROXY
unset HTTPS_PROXY
unset FTP_PROXY

Finally, to apply the proxy server configuration, execute the following command:

source /etc/environment

That’s all.
