So in this post ,you will learn setting proxy over several file so that working in system become easier.First you must have to where the changes has be done mean which files used for proxy authetication so there are several list of file in which you have set the proxy: 

1) .bashrc 

2) /etc/environment(for only cent OS or Red Hat based OS) in case of another OS(like Ubuntu) try to search for /etc/profie.d

3).bash.bashrc (if exists)

Steps to set proxy :

1. Open your terminal check already proxy are set or not first by typing this command:

 echo $http_proxy                                                                                                                                  

  Note: you need to check for several variable like same:

       

    $https_proxy,$HTTP_PROXY,$HTTPS_PROXY                                                                             

2. If there is alredy  set proxy you need to unset by hiting below command:

    

   unset $http_proxy                                                                                                                              

 Same for another variables also as same:  

                   

 unset  $https_proxy  $HTTP_PROXY  $HTTPS_PROXY

     Then check     echo $http_proxy

3. After unsetting proxy use below command for setting proxy inside .bashrc file ,and make sure   <usename>  and <password> must be correct ,and escape special character like @, #.

 This must be replace by following UTF code-

          

                  @          %40

                   #          %23

                   $          %24

                   !           %21

                   :           %3A

Example: A@B:C!D#EF$   should be change into  A%40B%3AC%21D%23EF%24

assign this string to one variable:

                  

 $PROXY  =  http://<username>:<password>@proxy_server:port 

         

Then assign this to variable one by one -

         

    $http_proxy =  http://<username<password>@proxy_server:port 

    $https_proxy =  http://<username<password>@proxy_server:port

    $HTTPS_PROXY=  http://<username<password>@proxy_server:port 

    $HTTPS_PROXY =  http://<username<password>@proxy_server:port 

This action must be perform in terminal.then hit this below commands: 

       export $http_proxy

       export $https_proxy

       export $HTTPS_PROXY

       export $HTTPS_PROXY      

Direct method:

    

 vim  ~/.bashrc                                                                                                                                        

        or 

 gedit ~/.bashrc                                                                                                                                       

paste these into .bashrc for cent OS inside /etc/environment 

 PROXY  =  http://<username<password>@proxy_server:port 

 http_proxy=  $PROXY  

 https_proxy=  $PROXY  

 HTTP_PROXY=  $PROXY  

 HTTPS_PROXY=  $PROXY
