How to generate a self signed certificate in ZMC

This article is for Amanda Enterprise (AE) and ZRM for MySQL (ZRM)

Info Type: Tip

Info Description:

  1. Move any existing keys:
# mkdir /root/ZMC_old_certs
#  mv /opt/zmanda/amanda/apache2/conf/certs/* /root/ZMC_old_certs
  1. Create a public/private key pair by entering the commands shown in bold below. Enter a secure passphrase (at least 8 characters, alphanumeric) when prompted. You must enter the same key twice for verification:
# cd /opt/zmanda/amanda/apache2/conf/certs
# /opt/zmanda/amanda/common/bin/openssl genrsa -des3 -out ZMC-server.key 1024
Generating RSA private key, 1024 bit long modulus

Enter pass phrase for ZMC-server.key:

  1. Create a certificate signing request. Answer any prompts as they are displayed.
# /opt/zmanda/amanda/common/bin/openssl req -new -key ZMC-server.key -out ZMC-server.csr
Enter pass phrase for ZMC-server.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [GB]:CA
State or Province Name (full name) [Berkshire]:Sunnyvale
Locality Name (eg, city) [Newbury]:Sunnyvale
Organization Name (eg, company) [My Company Ltd]:Zmanda.Inc
Organizational Unit Name (eg, section) []:support
Common Name (eg, your name or your server's hostname) []:ZMC
Email Address []:support@zmanda.com
Please enter the following 'extra' attributes
To be sent with your certificate request
A challenge password []:zmanda
An optional company name []:zmanda
  1. Generate a self-signed certificate.  When prompted for a passphrase enter the passphrase that you entered during key creation. The example shows creating a certificate that lasts for five years (1825 days); you can enter a different value if desired.
# /opt/zmanda/amanda/common/bin/openssl x509 -req -days 1825 -in ZMC-server.csr -signkey ZMC-server.key -out ZMC-server.crt
Signature ok
subject=/C=CA/ST=Sunnyvale/L=Sunnyvale/O=Zmanda.Inc/OU=support/CN=ZMC/
emailAddress=support@zmanda.com
Getting Private key
Enter pass phrase for ZMC-server.key:
  1. The certificate should be changed to use a key with no passphrase to avoid being prompted for the password and to allow for integration with ZMC.  When prompted for a passphrase enter the passphrase that you entered during key creation. The example shows removing a passphrase from previously created certificate.
# mv ZMC-server.key ZMC-server.key.has-passphrase
# /opt/zmanda/amanda/common/bin/openssl rsa -in ZMC-server.key.has-passphrase -out ZMC-server.key
  1. Change permissions so the key can only be read by root.
# chmod 400 ZMC-server.key
  1. Restart the ZMC. Enter the passphrase when prompted.
# /etc/init.d/zmc_aee restart or /etc/init.d/zmc_zrm restart
