How To Configure Yum Behind Authenticated Proxy Server

on December 1 | in Linux, Programming / Scripting | by | with 31 Comments

This how to describe to configure YUM to work behind proxy server using username / password for authentication. YUM is great tool available in RHEL/Fedora/CentOS to install/update/remove packages easily from local and internet repositories. In the most offices / schools / colleges where proxies are implemented and direct connection to the internet is not possible and all internet traffic goes through proxy servers. Same as in my office we have to use proxy server with username / password to authenticate ourself to get internet access. So we are going to configure my YUM software to use proxy to get my LINUX updated with new softwares all the times with repositories available on internet.

OS = Fedora 10

1) Configure yum.conf

vi /etc/yum.conf

enter following lines at bottom of [main] section

proxy=http://yourproxyaddress:port/
proxy_username=youruser
proxy_password=yourpassword

2) Export http_proxy variable

export http_proxy=”http://yourproxyaddress:80/”

3) Export http_proxy variable in bash login script

vi /root/.bash_profile

export http_proxy=”http://yourproxyaddress:80/”

This will help you to export http_proxy variable automatically everytime you login.

Now use “yum list” command to check for its working.

yum list

Enjoy Brothers 🙂

  5. Esteban says:

    En mi caso, el servidor proxy no cuenta con usuario ni password para acceder, asi que los omiti.
    La cuestion es que a la primera no funciono, solo despues de colocar 10.11.12.9:8080, y dio error, luego volvi a poner http://10.11.12.9:8080/ y funciono ok.
    Pero una duda, la variable http_proxy que objetivo cumple.
    Gracias

    How to give windows domain username and password?

  10. Siju says:

    i tried with
    domain\username, but it never works

  11. @Siju: First you need to see whether your domain user/pass is been used to access the internet or not. As per mine in above instruction I am using it and it working absolutely fine.
    The above username i given is of Windows Domain user/pass which is same as our internet access.

    Check your settings again, you might has miss something.

    My proxy password contains @ and this error occurred

  24. @Williiam: You can use escape character like back slash before @ symbol like this \@ to avoid this error.

    I have been looking for an option to use DOMAIN\Username and password, but it does not works. Probably because I have few special chars in my password (like @ and #).
