Red Hat Summit第1章 Preparing your Environment for Installation
1.1. System Requirements
The following requirements apply to the networked base operating system:
- x86_64 architecture
- The latest version of Red Hat Enterprise Linux 7 Server
- 4-core 2.0 GHz CPU at a minimum
- A minimum of 12 GB RAM is required for Capsule Server to function. In addition, a minimum of 4 GB RAM of swap space is also recommended. Capsule running with less RAM than the minimum value might not operate correctly.
- A unique host name, which can contain lower-case letters, numbers, dots (.) and hyphens (-)
- A current Red Hat Satellite subscription
- Administrative user (root) access
- A system umask of 0022
- Full forward and reverse DNS resolution using a fully-qualified domain name
Before you install Capsule Server, ensure that your environment meets the requirements for installation.
Capsule Server must be installed on a freshly provisioned system that serves no other function except to run Capsule Server. The freshly provisioned system must not have the following users provided by external identity providers to avoid conflicts with the local users that Capsule Server creates:
- postgres
- mongodb
- apache
- qpidd
- qdrouterd
- squid
- foreman-proxy
- puppet
- puppetserver
For more information on scaling your Capsule Servers, see Capsule Server Scalability Considerations.
Certified hypervisors
Capsule Server is fully supported on both physical systems and virtual machines that run on hypervisors that are supported to run Red Hat Enterprise Linux. For more information about certified hypervisors, see Which hypervisors are certified to run Red Hat Enterprise Linux?.
SELinux Mode
SELinux must be enabled, either in enforcing or permissive mode. Installation with disabled SELinux is not supported.
FIPS Mode
You can install Capsule Server on a Red Hat Enterprise Linux system that is operating in FIPS mode. For more information, see Enabling FIPS Mode in the Red Hat Enterprise Linux Security Guide.
