Red Hat NETWORK PROXY 5.3.0 -, Руководство по установке

Страница: 10 / 48

Chapter 2. Requirements
6
• Access to the Red Hat Network Tools channel for the installed version of Red Hat Enterprise
Linux. This channel includes the
spacewalk-proxy-installer
package that contains the
configure-proxy.sh
installation program required to install RHN Proxy Server.
• All
rhncfg*
packages installed on the Proxy (from the RHN Tools channel).
• Either the
rhns-certs-tools
package installed on the Proxy (from the RHN Tools channel) for
RHN Hosted users, or the secure sockets layer (SSL) CA certificate password used to generate the
parent server certificate for RHN Satellite Server users.
• Configuration of the system to accept remote commands and configuration management through
Red Hat Network if using the deprecated Web UI installation method. Refer to
Section 4.2, “RHN
Proxy Server Installation Process”
for instructions.
2.2. Hardware Requirements
The following hardware configuration is required for the RHN Proxy Server:
• A Pentium IV Processor or equivalent
• 512 MB of memory
• At least 5 GB storage for base install of Red Hat Enterprise Linux
• 25+ GB storage per distribution/channel
The load on the Apache Web server is directly related to the frequency with which client systems
connect to the Proxy. If you reduce the default interval of four hours (or 240 minutes) as set in the
/
etc/sysconfig/rhn/rhnsd
configuration file of the client systems, you will
increase
the load on
this component significantly.
Note
RHN Proxy Server does not support kickstart provisioning on multi-homed network
topologies. Kickstarts will not function properly on a Proxy server that has more than
one network interface.
2.3. Disk Space Requirements
The caching mechanism used by RHN Proxy Server is the Squid HTTP proxy, which saves significant
bandwidth for the clients. It should have a reasonable amount of space available. The cached
packages are stored in
/var/spool/squid
. The required free space allotment is 6 GB storage per
distribution/channel.
If the RHN Proxy Server is configured to distribute custom, or local packages, make sure that the
/var
mount point on the system storing local packages has sufficient disk space to hold all of the
custom packages, which are stored in
/var/spool/rhn-proxy
. The required disk space for local
packages depends on the number of custom packages served.
