Chapter Review

This short chapter was intended to introduce the concept of using Web servers on HP-UX. HP provides ObAM management tools via a cut-down version of the ever-popular Apache Web server. The full-blown Apache Web server is a free addition to HP-UX, and the configuration file straight out of the box can get a Web server up and running quickly and easily. The default Web page offers extensive help in setting up and managing a Web server. HP looks to be continuing and expanding its use of a Web interface to manage HP-UX. Service Control Manager is currently at version 3.00.04, which utilizes a new standard for management tools known as WBEM , Web-Based Enterprise Management. WBEM allows customers to manage their systems consistently across multiple platforms and operating systems, providing integrated solutions that optimize your infrastructure for greater operational efficiency. WBEM enables management applications to retrieve system information and request system operations wherever and whenever required. See http://www.hp.com/large/infrastructure/management/wbem/ for more details. At its core , Service Control Manager utilizes a Tomcat Web server. Service Control Manager has components that run on HP-UX as well as Linux. From a Central Management Station, we can manage up to 1024 nodes. The software integrated into Service Control Manager includes the following:

  • System Administration Manager (SAM)

  • Ignite-UX

  • Software Distributor-UX (SD-UX)

  • Event Monitoring Service (EMS)

  • System Inventory Manager (SIM)

  • Security Patch Check

  • Process Resource Manager (PRM)

  • HP-UX Workload Manager (WLM)

  • Partition Manager

  • Serviceguard Manager

  • Kernel Configuration

  • Common HP-UX and Linux commands

This is the future of System Management!

     

Test Your Knowledge

1:

Each instance of a Web server (this could constitute a number of individual httpd daemon processes) will have its own independent configuration file. True or False?

2:

Select all of the following that are true:

  1. The ObAM-Apache Web server uses the same configuration file as the full-product Apache Web server.

  2. The ObAM-Apache Web server listens on port 1188 by default.

  3. The ObAM-Apache Web server supports virtual hosting.

  4. The ObAM-Apache Web server supports Dynamic Shared Modules in the same way as the full-product Apache Web server.

  5. The ObAM-Apache Web server does not support encryption capabilities such as SSL.

3:

You must configure the DNS resolver configuration file before the ObAM-Apache-based Web server will start up successfully. True or False?

4:

The httpd.conf file can contain a directive called MaxSpareServers . This controls how many httpd daemons are initially started up. True or False?

5:

If we are going to allow Web traffic through a firewall, we will need to know the port number used by each Web server running on our system. The port number being used by each Web server is documented in the relevant http.conf file under the Port directive. True or False?

     

Answers to Test Your Knowledge

A1:

True.

A2:

Answers B and E are correct.

A3:

False. While the webadmin startup script may check for the existence and check the content of the /etc/resolv.conf file, this can be circumvented by updating the httpd.conf file to allow access from any DNS domain.

A4:

False. The directive that controls the initial number of httpd daemons is the StartServers directive.

A5:

True.
