HDP 3.0 Error: Cannot find a valid baseurl for repo: base/7/x86_64 (Urgent)

Hi All,

We are facing issue installing using Local Repositories as don't have internet access in our environment. This issue is pending since last 2 weeks and we are unable to crack this via any forum or community.

Error: Cannot find a valid baseurl for repo: base/7/x86_64

-------------------------------------------------

Ambari Agent: Pending
HDP 3.0: Pending

-----------------------------------------------------------------------------------

Issue: Using local repositories, whenwe run this command: yum install ambari-server following error hit us.

Error:

[root@ufm yum.repos.d]# yum install ambari-server

Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"

One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this:

1. Contact the upstream for the repository and get them to fix the problem.

2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work).

3. Run the command with the repository temporarily disabled

yum --disablerepo=<repoid> ...

4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage:

yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid>

5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise:

yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/7/x86_64

-----------------------------------------------------------------------------------

Note: Above whole installation was achieved on

Local VM enviroments but not on ESXI (this is our first time on EXSI environment)
Bare Metal Servers

Limitation: We do not have internal access in our environment, so have to use local repositories.

Looking forward.

Cheers

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os∈fra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"

The above error indicates that you still have some of the Repositories pointing to Public URL.

Please open those files "/etc/yum.repos.d/*.repo" and then disable them which are using Public base_url By setting "enabled=0"

1. Find the REPO files which are using public repos:

# grep baseurl /etc/yum.repos.d/*.repo

2. Then open the file which has public pointing repo URL (Instead of pointing to your Local repo host). and then disable it by setting "enabled=0"

3. Perform yum clean all and then continue installing ambari.

# yum clean all

More detailed steps on setting up a Local repo can be found here:

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.0/bk_ambari-installation/content/setting_up_a_local_repository_with_no_internet_access.html

Also please make sure that you have the "/etc/yum.repos.d/ambari.repo" file pointing to your Local Repo.

We moved ahead by disabling rest the repos and enabling ambari one but got stuck at cluster building.

Note: When we paste this URL: http://ufm.hadoop.com/repo/HDP/centos7/3.0.0.0-1634/repodata/repomd.xml it does work.

@Jay Kumar SenSharma @Geoffrey Shelton Okot

It seems, repodata/repomd.xml is the culprit.

Please advice its uses and content with no-internet access as its content is;

<?xml version="1.0" encoding="UTF-8"?> <repomd xmlns="http://linux.duke.edu/metadata/repo" xmlns:rpm="http://linux.duke.edu/metadata/rpm">

I feel above mentioned URLs should not go on internet.

As requested earlier that youa re getting 503 error while accessing the Local Repo Which means your WebServer where you have placed your Repo might be having some issue.

Hence can you please share your WebServer logs (httpd logs when you noticed 503 error).

Hi,

Apologies for delay.

There you go with WebServer Log.

Note: As this is offline line installation, we don't have index.html any where.

Please advice.

jsensharma — Sun, 23 Sep 2018 22:15:43 GMT

@Mustafa Ali Qizilbash

As we see that the error basically is from your webserver where you have setup the local repo:

AH00035: access to /repo/repodata/index.html denied (filesystem path '/var/www/html/repo/repodata/index.html') because search permissions are missing on a component of the path

The above kind of error mostly occurs if you have not given proper permissions to your Local repo directories. Please refer to the following doc to get more details about the webserver error "AH00035: access denied because search permissions are missing on a component of the path" : https://wiki.apache.org/httpd/13PermissionDenied

Try setting the proper permission to your Web Server repo directories.

find /var/www -type d -exec chmod 755 {} \;
find /var/www -type f -exec chmod 644 {} \;

Then restart your webserver and then try again.

@Jay Kumar SenSharma

Yup permissions are good.

The problem is, there is no index.html file present in/repo/repodata directory.

@Jay Kumar SenSharma

So we moved ahead and used another IP: XX.XX.XX.51 (which has internet access) to install HDP and then reverted HDP back to its original IP: XX.XX.XX.160 (which does't have internet access) and did the same to install HDF using IP: XX.XX.XX.51 (which has internet access) and then reverted HDF back to its original IP: XX.XX.XX.161 (which doesn't has internet access).

When HDP and HDF were on IP: XX.XX.XX.51, all the services were up and running and restart-able but the moment those were reverted back i.e. HDP and HDF to those original IPs, everything got hung. Now services are in start mode as were when were on IP: XX.XX.XX.51 and we can't stop & restart and other things like hive is not accessible, NiFi UI does't appear etc.

Please advice.
