Cloudera Manager Installation failed with PostgreSQL dependency

[#1]

Hello,

I am trying to deploy a POC cluster using Path A of Cloudera Manager installation documentation. However, it is failing with below message in the logs:

cat 5.install-cloudera-manager-server-db-2.log 
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Resolving Dependencies
--> Running transaction check
---> Package cloudera-manager-server-db-2.x86_64 0:5.15.1-1.cm5151.p0.3.el7 will be installed
--> Processing Dependency: postgresql-server >= 8.4 for package: cloudera-manager-server-db-2-5.15.1-1.cm5151.p0.3.el7.x86_64
--> Finished Dependency Resolution
Error: Package: cloudera-manager-server-db-2-5.15.1-1.cm5151.p0.3.el7.x86_64 (cloudera-manager)
           Requires: postgresql-server >= 8.4
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I also tried to use local repository and point .bin file using --skip_repo_package=1. However,

1. Was unable to find packages for PostgreSQL 8.4 any where, so created repo of 9.6 instead.
2. CM at the first place hunts for PostgreSQL 8.4, and then finds 9.6 in the repo, however, fails at dependency check. It still needs few dependent packages (5-6) to proceed.

Before I download each package and put it in repo, seeking suggestions / help from the community on why is the installation with Cloudera repos (installation path A) failing with that message.

Thanks

@snm1523,

Since you are using install path A, the installation will attempt to install cloudera-manager-server-db-2 which requires postgres server. Note that you need postgres >= 8.4 (not equal to)

yum will attempt to download and install a postgres server, but in your case it cannot find any.

Can you install posgresql-server manually with "yum?"

This thread may have some relevant info too:
