Tweak Settings  Məqaləni çap et

Overview:

This interface allows you to configure many cPanel & WHM settings. Tabs at the top of the interface categorize the settings, and the All tab displays all of the settings.

Note:

  • These settings exist in the /var/cpanel/cpanel.config file. However, we recommend that system administrators use this interface to make changes.

  • Some settings may not appear if your server does not use the Standard Node server profile. For more information, read our How to Use Server Profiles documentation.

  • Click the question mark next to each setting’s description to learn more about the setting.

  • The interface displays a warning icon (yellow warning icon) next to any setting for which you have not specified a value. This includes settings that are new, settings that WHM has set to a default value, and settings that your server selected dynamically.

Compression

The Compression section includes the following settings:

Setting Description Values Default
gzip compression level This setting allows you to set the gzip compression level for pigz, which is a gzip-compatible program that uses multiple CPU cores simultaneously. Higher settings provide greater compression, but compress more slowly.
  • Minimum value: 1
  • Maximum value: 9
 6
Number of pigz processes This setting allows you to set how many independent pigz processes the system uses to perform gzip compression. For the best performance, we recommend that you set this value to match the number of processor cores that are available on your server.
  • Minimum value: 1
  • Maximum value: 128
 This setting defaults to the number of processor cores on your server.
Number of kilobyte chunks per compression work unit This setting allows you to control the size, in 1024-byte chunks, of compression work units that the system distributes to each pigz process.
  • Minimum value: 128

Development

The Development section includes the following setting:

Setting Description Values Default
Standardized Hooks - Debug Mode The Standardized Hooks system’s debug mode helps to troubleshoot hook issues. For more information, read our Guide to Standardized Hooks - Debug Mode documentation.
  • If, instead of this setting, you use the /var/cpanel/debughooks file to enable debug mode, your locale may revert to the English defaults for JavaScript elements. To fix this problem, run the echo -n > /var/cpanel/debughooks and /scripts/restartsrv_cpsrvd commands to disable debug mode and restart the cpsrvd daemon.
  • When you enable this setting, it will also enable debug mode in the cPanel interface. This will severely impact the loading and performance of the cPanel interface. We recommend that you disable this setting when you do not need it.
  • Debug mode is off. — The system does not display debug information or log it to the error log.
  • Debug mode is on. The system displays information about a hook while it executes, but does not log debug data to the error log.

The /scripts/enable_spf_dkim_globally script allows you to enable SPF and DKIM for accounts that exist on the server, and to create the appropriate DNS records for their domains. For more information, read our The SPF and DKIM Global Settings Script documentation.
  • On — Enable DKIM.

This reduces the amount of backscatter that you receive. This setting allows you to specify whether to enable SPF for new accounts by default.
The /scripts/enable_spf_dkim_globally script allows you to enable SPF and DKIM for accounts that exist on the server, and to create the appropriate DNS records for their domains. For more information, read our The SPF and DKIM Global Settings Script documentation.
