Puppet Class: apache::mod::itk

Defined in:
manifests/mod/itk.pp

Summary

Installs MPM `mod_itk`.

Overview

Note:

Unsupported platforms: CentOS: 8; RedHat: 8, 9; SLES: all

Parameters:

  • startservers (Integer) (defaults to: 8)

    Number of child server processes created on startup.

  • minspareservers (Integer) (defaults to: 5)

    Minimum number of idle child server processes.

  • maxspareservers (Integer) (defaults to: 20)

    Maximum number of idle child server processes.

  • serverlimit (Integer) (defaults to: 256)

    Maximum configured value for ‘MaxRequestWorkers` for the lifetime of the Apache httpd process.

  • maxclients (Integer) (defaults to: 256)

    Limit on the number of simultaneous requests that will be served.

  • maxrequestsperchild (Integer) (defaults to: 4000)

    Limit on the number of connections that an individual child server process will handle.

  • enablecapabilities (Optional[Variant[Boolean, String]]) (defaults to: undef)

    Drop most root capabilities in the parent process, and instead run as the user given by the User/Group directives with some extra capabilities (in particular setuid). Somewhat more secure, but can cause problems when serving from filesystems that do not honor capabilities, such as NFS.
