CA (Certificate Authority) Bundle: A file on your server that verifies that your public and private keys were issued by a trusted entity. If your Certificate Authority sent you a CA bundle file, you can install it to your server using WHM’s Install a SSL Certificate and Setup the Domain feature, or the Manage Service SSL Certificates feature.
Certificate (Public Key Certificate): An electronic document that states the identity of a server so that the end user knows that he or she is communicating with the correct website.
Certificate Authority: An entity that issues digital certificates for server verification.
Certificate Signing Request (CSR): A request for a certificate sent by a server’s administrator to a certificate authority.
BoxTrapper: An application included with cPanel that filters spam by requiring would-be senders to reply to a verification email (also known as challenge-response verification). Only after the sender is verified through the reply will his or her original email be accepted.
BoxTrapper Blacklist: A list of email addresses from which incoming mail will be automatically blocked by the BoxTrapper application. cPanel automatically sends a configurable warning message upon receipt of mail from a blacklisted address.
BoxTrapper Ignore List: A list of email addresses from which incoming mail will be blocked. cPanel does not send a warning message upon receipt of mail from an address ignored by the BoxTrapper application.
BoxTrapper Whitelist: A list of email addresses from which incoming mail will automatically be accepted by the BoxTrapper application. See also BoxTrapper Ignore List and BoxTrapper Blacklist.
WHM Scripts
When cPanel and WHM is installed, a number of predefined scripts become available in your server’s /scripts directory.
For example, if you wanted to run the update script, you would type:
#easyapache — Upgrades and reinstalls Apache.
#phpextensionmgr — Manages PHP extensions.
# restartsrv_* — Restarts a service.
# *up — Updates a service.
* bandminup — Bandmin application.
* courierup — Courier mail server.
* cpaddonsup — cPanel’s addon scripts.
* dovecotup — Dovecot mail server.
* eximup — Exim mail exchanger.
* ftpup — FTP servers (ProFTP and Pure-FTP).
* imapup — IMAP mail server.
* mysqlup —MySQL service.
* nsdup — BIND nameserver.
* phpup — Current version of PHP.
* suphpup — SuPHP tool for handling PHP requests.
Find if ssl certificate and key are paired correctly.
To view the contents of a certificate:
openssl x509 -noout -text -in filename.crt
To view the contents of a private key:
openssl rsa -noout -text -in filename.key
If the modulus number and exponent of the cert and key match, they are paired correctly. If not, they are mismatched and apache will not start with ssl enabled.
Selecting a cPanel Build Type Pre-Installation
You can define your build type by defining the variable CPANEL. cPanel offers 4 build types to choose from: stable, release, current, and edge.
To choose the build type, add 1 of the 4 following lines to /etc/cpupdate.config.
* CPANEL=stable
* CPANEL=release
* CPANEL=current
* CPANEL=edge
The cPanel and WHM interfaces will be installed according to which of the 4 options you define in the configuration file.
