NetBackup IT Analytics Data Collector Installation and Configuration Guide for Cohesity NetBackup

Obtain an SSL certificate

Obtain a third-party certificate from a certificate authority (CA) such as VeriSign, Thawte, or GeoTrust. The methods for obtaining a certificate vary. Therefore, refer to the vendor's web site for specific instructions.

You may, for testing purposes or as a permanent solution, use a self-signed certificate. This is not recommended as it makes the implementation slightly more complex and may limit access to NetBackup IT Analytics to some of your users.

The following outlines the process for creating a Subject Alternative Name (the certificate covers more than one hostname under a single certificate) self-signed certificate on a Linux operating system. Steps will be similar on Windows. This certificatesecures communication for both the portal and data receiver web instances.

cd /tmp 

vi san.cnf

Sample san.cnf file - use this faile as a template and modify this for your environment. The san.cnf file will be an input parameter during certificate generation. Note the use of an example domain name of example.com; change this to own your environment's domain name.

Under the v3 section, in addition to the portal name, also provision the data receiver under this same certificate.

[ req ] 
default_bits = 4096 
prompt = no	 
default_md = sha256 
distinguished_name = req_distinguished_name 
x509_extensions = v3_req 

[ req_distinguished_name ] 
C = US 
ST = New York 
L = New York City 
O = Veritas 
OU = ITA 
emailAddress = aReal.emailaddress@yourdomain.com 
CN = itanalyticsportal.example.com   

[ v3_req ] 
subjectAltName = @alternate_names   

[alternate_names] 
DNS.1 = itanalyticsportal.example.com 
DNS.2 = itanalyticsagent.example.com 

  

The following command results in the private key name of server.key, and certificate name of server.crt. These names will be used through the remainder of this chapter. You are free to use different names for the certificate and private key files if desired. With this command, we are also creating a self-signed certificate for 3650 days, or 10 years.

openssl req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes -keyout server.key -out server.crt -config /tmp/san.cnf
