Yum Https Proxy

yum update through a proxy https – CentOS Forums

Hi guys!
I am trying to update my Centos 6 whith ‘yum update’. The problem is that my enterpriss uses a proxy configured with a script
I configured the file /etc/profile:
export _proxy=user:[email protected]:port
But it does not work.
The Internet explorer in the enterprise is configured to get the proxy with a script, like that:
‘automatic configuration script ‘
The script is:
function FindProxyForURL(url, host) {
if(isPlainHostName(host) || isInNet(host, “10. 0. 0”, “255. 0”) || isInNet(host, “172. 18. 240. 0”) || isInNet(host, “192. 168. 255. 0”) || isInNet(host, “200. 183. 77. 11. 278. 224. 0”) || shExpMatch(url, “**”) || shExpMatch(url, “**”) || shExpMatch(url, “*granulito**”)) {
if( shExpMatch(url, “”)) {
return “PROXY “;}
else {
return “DIRECT”;}}
if(shExpMatch(url, “*:443/*”) &&! shExpMatch(url, “**”)) {
else if(shExpMatch(url, “:*”) &&! shExpMatch(url, “**”)) {
else return “DIRECT”;}}
I am new with linux and i am really get lost.
How must i configure the proxy client in Centos to make the ‘yum update’ work?
Thanx so much!!!!!

In most of the data center direct Internet connection is not allowed on Unix and Windows Servers. If we need to download anything from Internet we have to go through via some proxy servers. In case of Linux Servers whenever we need to install new packages and apply patches in such scenarios we have to set proxy for yum command.
This can be easily achieved with yum config file “/etc/“. Under main section define the proxy settings like below:
[main]
………………
proxy=:
proxy_username=
proxy_password=
Save and exit the file and start using the yum command. Sample yum Config file with proxy settings is shown below:
Just for the verification you can run beneath command to see whether you are able to fetch the packages or not.
[[email protected] ~]# yum repolist
Alternate way to configure proxy settings for yum command
Set the following variables in either of the file “/etc/environment” or “/root/”……………………………………………………………
export _proxy={Proxy-User-Name}:{Proxy-Password}@:
export _proxy= {Proxy-User-Name}:{Proxy-Password}@:
export ftp_proxy= {Proxy-User-Name}:{Proxy-Password}@:
export no_proxy=127. 0. 1, localhost………………………………………………………….
Above proxy settings will be applicable system wide.

10. Using yum with a Proxy Server
By default, yum accesses network repositories
with HTTP. All yum HTTP operations use
HTTP/1. 1, and are compatible with web proxy servers that support
this standard. You may also access FTP repositories, and configure
yum to use an FTP proxy server. The
squid package provides a proxy service for
both HTTP/1. 1 and FTP connections.
Modifying yum for Network Compatibility
Refer to the man page for
for information on HTTP settings
that may be modified for compatibility with nonstandard web
proxy servers. Alternatively, configure yum
to use an FTP proxy server, and access repositories that support
FTP. The Fedora repositories support both HTTP and FTP.
10. 1. Configuring Proxy Server Access
To enable all yum operations to use a proxy
server, specify the proxy server details in
/etc/ The proxy
setting must specify the proxy server as a complete URL,
including the TCP port number. If your proxy server requires a
username and password, specify these by adding
proxy_username and
proxy_password settings.
The settings below enable yum to use the
proxy server,
connecting to port 3128, with the username
yum-user and the
password qwerty.
# The proxy server – proxy server:port number
proxy=# The account details for yum connections
proxy_username=yum-user
proxy_password=qwerty
Example 3. Configuration File Settings for Using A Proxy ServerGlobal Settings
If you define a proxy server in
/etc/, all
users connect to the proxy server with those details when
using yum.
10. 2. Configuring Proxy Server Access for a Single User
To enable proxy access for a specific user, add the lines in the
example box below to the user’s shell profile. For the default
bash shell, the profile is the file
~/. bash_profile. The settings below enable
yum to use the proxy server,
connecting to port 3128.
# The Web proxy server used by this account
_proxy=”
export _proxy
Example 4. Profile Settings for Using a Proxy Server
If the proxy server requires a username and password, add these
to the URL. To include the username
password qwerty, add these settings:
# The Web proxy server, with the username and password for this account
_proxy=”yum-user:[email protected]:3128″
Example 5. Profile Settings for a Secured Proxy ServerThe _proxy Environment Variable
The _proxy environment variable is also
used by curl and other utilities. Although
yum itself may use
_proxy in either upper-case or
lower-case, curl requires the name of the
variable to be in lower-case.
