Cannot disable yum proxy

[johnbellone]

Using the following Vagrantfile (and setting the environment variables) does not seem to work:

Vagrant.configure('2') do |config|
  config.yum_proxy.http = false
end

Where the environment variables are:

VAGRANT_HTTP_PROXY=$HTTP_PROXY
VAGRANT_HTTPS_PROXY=$HTTPS_PROXY

I've also tried setting VAGRANT_YUM_HTTP_PROXY to nil and it also does not work. Unfortunately I run into this because the image I am provisioning on is already setup with a local RedHat satellite cache for RPMs.

[tmatilai]

Hmm, config.yum_proxy.http = false should have higher precedence as VAGRANT_HTTP_PROXY environment variable. But it causes the proxy settings to be removed from the yum config. Is that what you are seeing?

The false for environment variables is empty string. nil causes the variable to not be set at all.

But yeah, I didn't think there would be need for ignoring a config while configuring globally otherwise. I think I'll introduce the enabled attribute to all config classes. I.e. config.yum_proxy.enabled = false and VAGRANT_YUM_PROXY=. I had already planned (and maybe even started, can't remember) some refactoring for those config classes so this fits well there.

But might take some days, as I'm still recovering from an intercontinental moving with my family. =)

hi@all
It is not possible to work with buggig plugin because proxy for yum is always false and yum can not get network connection on instal/update needed packages.

below maybe helpful outputs to fix this behav. thx for the fixation in advance!

BTW I get trouble with setting of proxy for npm here is the output for

% vagrant provision

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

/usr/bin/npm config delete proxy

and cut from Vagrantfile

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

    # auto detect proxy values from environment

@olekhy what vagrant-proxyconf version are you using? Could you please add a link to a gist of full --debug output of a failed Vagrant run.

[olekhy]

1. % vagrant destroy

2. % vagrant plugin install vagrant-proxyconf
   Installing the 'vagrant-proxyconf' plugin. This can take a few minutes...  
   Installed the plugin 'vagrant-proxyconf (1.3.1)'!`  

3. % vagrant up --debug produce error npm remove proxy see vagrant.debug.log
4. I've get fixed by creating empty file /root/.npmrc as u see in vagrant.debug.log at line 34847 after log in vagrant box.
   npm ERR! Error: ENOENT, unlink '/root/.npmrc'
5. % vagrant provision --debug
6. show the ERROR message exact on line 52693 in vagrant.provision.debug.log

@olekhy thanks a lot, the information really helps!

The first issue is clearly an NPM bug. IT has been reported multiple times (and even by you!): npm/npm#5065, npm/npm#5160, npm/npm#5223. But we can hack around it by creating the rc file if needed.

The yum issue is still a mystery. Based on the logs it seems that vagrant-proxyconf works as expected. I have to see if I can reproduce it (on CentOS I guess).

[olekhy]

Yep centos6. If needed I can paste an URL to the box which we used in vagrant.

[tmatilai]

That would probably help. I don't normally work with CentOS and have been using some Bento boxes for testing.

[olekhy]

config.vm.box_url = "https://s3-eu-west-1.amazonaws.com/toolbox.omnidoo.de/vm-images/12.01.2014-omnidoo-dev-centos6_x86_64.virtualbox.box"

[tmatilai]

Sorry, haven't found time for this yet. Trying hard on Thursday.

[olekhy]

Many thx for this because I work by the (crappy) way at office need to install proxyconf and set up proxy in Vagrantfile otherwise at home reverting all.

[tmatilai]

@olekhy OK, finally found the time to reproduce the yum issue, and it was actually bug in writing /etc/environment. That and the npm issue should now be fixed in master. I plan on releasing them tomorrow.

[tmatilai]

Fyi, the npm bug should be fixed in npm v1.4.17 and later.

And the yum bug in vagrant-proxyconf v1.3.2.

[olekhy]

thx 🙇

fastestmirror still causes issues https://wiki.centos.org/PackageManagement/Yum/FastestMirror says

If you are using the default CentOS configuration, and if you are not behind a proxy server, fastestmirror is highly recommended.

So I think it should be disabled because we are behind a proxy server, I am still having issues with it.

sudo sed -i 's/.*enabled=.*/enabled=0/g' /etc/yum/pluginconf.d/fastestmirror.conf

patch #148 disables
