SSL Configuration on Linux[Red Hat Enterprise Linux Server release 7.2 (Maipo)]

AviralSri asked:

My Linux distro : Red Hat Enterprise Linux Server release 7.2 (Maipo)
Configuring ssl on this software
Kibana-4.3.0-linux-x64

I am trying to configure ssl on kibana.

The steps I followed:

1. Generated private key

   openssl genrsa -out privatekey.key 2048
   

   The above command created a file names privatekey.key .

2. Genrated CSR

   openssl req -new -key privatekey.key -out linux.csr
   

   Entered the details this csr asked. and then linux.csr file was created.

3. I submitted this linux.csr to my organization and I was issued a certificate certnew.cer
   The certificate contents were like:

   -----BEGIN CERTIFICATE-----
   -----END CERTIFICATE-----
   

4. Now kibana-4.3.0-linux-x64 folder was present on home path of linux machine
   I made the following changes to kibana.yml file

   ssl.server..cert : /home/.../certnew.cer
   ssl.server.key : /home/.../privatekey.key
   

5. Now, I start kibana and get the following log:-
   In the log it says:

   log [17:49:38.853] [info][status][plugin:kibana] Status changed from uninitialized to green - Ready
   log [17:49:38.925] [info][status][plugin:elasticsearch] Status changed from uninitialized to yellow - Waiting for Elasticsearch

   log [17:49:39.002] [info][status][plugin:spyModes] Status changed from uninitialized to green - Ready
   log [17:49:39.009] [info][status][plugin:elasticsearch] Status changed from yellow to green - Kibana index ready
   log [17:49:39.013] [info][status][plugin:statusPage] Status changed from uninitialized to green - Ready
   log [17:49:39.021] [info][status][plugin:table_vis] Status changed from uninitialized to green - Ready
   log [17:49:39.046] [info][listening] Server running at https://xx.xx.xx.xxx:8601
   

In the Browser when I try to open https://xx.xx.xx.xxx:8601. It runs but it is specified as Not secure and https is crossed in red colour.
Can anybody help me what steps I am missing ?

What I understand is that I need to add ssl certificate [certnew.cer] or maybe privatekey[privatekey.key] to linux trusted list which I suppose. Can anybody help me with that or point me to a link
