Chapter 13. Updating and Removing Subsystem Packages

Certificate System is installed using individual packages for each of its subsystems and its supporting systems, like Red Hat Directory Server and NSS. This makes the Certificate System modular, and each individual subsystem and its packages can be installed, updated, and removed independently.

13.1. Updating Certificate System Packages

There are many packages, listed in Section 5.2, “Packages Installed on Red Hat Enterprise Linux”, installed with Certificate System for related applications and dependencies, not just the subsystem packages. For all supported platforms, individual Certificate System packages may be updated through the native package utility, yum.

NOTE

All Certificate System instances must be stopped before beginning any updates.

The recommended way to update packages is to use yum to manage the updates.

Stop all Certificate System instances.
```
service instance_ID stop
```
Log in as root.

Run yum for the package. For example:

yum update pki-java-tools-8.1.0-4.noarch

Or simply:

yum update pki-java-tools

Restart the Certificate System instances.
```
service instance_ID start
```

Alternatively, any updated RPMs can be downloaded and installed manually.

Stop all Certificate System instances.
```
service instance_ID stop
```
Log in as root.

Install the updated package.

rpm -Uvh package_name

For example:

rpm -Uvh pki-java-tools-8.1.0-4.noarch.rpm

Restart the Certificate System instances.
```
service instance_ID start
```
