Re: Unable to load logon screen of Ambari Web ui

Hi Yusaku,

As suggested I have tried the commands.
npm -version works fine.

But due to limited internet access (proxy issue), i am not able to install brunch.
npm install -g brunch

Can you provide the path of the repo from where we can get the dump RPMs.

I just followed the install instructions for 1.4.1 [1] and I was able to build, install the resulting RPMs, and bring up the Ambari Web UI just fine.
As I was going thru the instructions, I did update the 1.4.1 tarball URL as it was returning 404 (as the tarball location moved).

Since /usr/lib/ambari-server/web is empty on your machine, most likely ambari-web build failed.

Please try the following:
# npm --version <- make sure the npm command works. This command is part of NodeJS.  If not, install NodeJS from http://nodejs.org/download/.  Just download the binary tarball, extract, and put the bin folder in PATH.
# npm install -g brunch <- this installs brunch
# cd ambari-1.4.1-incubating/ambari-web/
# rm -rf public
# npm install <- this command should create a subfolder called node_modules
# brunch build <- this command should create a subfolder called public

Also, you might want to try building off of trunk [2], 1.4.3 (a release candidate vote was called today), or 1.4.2 [3]

Hi Yusaku,

I am following apache Ambari user guide instructions to install Ambari.Following is the link:

https://cwiki.apache.org/confluence/display/AMBARI/Build+and+Install+Ambari+1.4.1


I have created RPMs from source through maven build.
And also /usr/lib/ambari-server/web/ directory exists on ambari-server host but no content is present in this directory like index.html or _javascript_s/app.js. This web directory is empty.

Please suggest any solution for the same.

Hello Meghavi,

Which instructions are you following to install Ambari?  (You said it was an RPM install... did you create the RPMs yourself from source, or did you grab them from a repo?)
Can you check and see if /usr/lib/ambari-server/web/ directory exists on the Ambari server host?
If so, do you see a file called index.html in that directory, and also _javascript_s/app.js?

Check your firewall? Start Ambari-server if not started,

 

Run: netstat –tunlp | grep 8080 on the Ambari server
