KUSANAGI Plug-ins

KUSANAGI plug-ins

KUSANAGI plug-ins are bundled with KUSANAGI and ready to use. The plug-ins include accelerating features such as Page Cache and Translate Accelerator, as well as a theme switching feature.

Feature Summary

Page Caching

Page Caching temporarily saves HTML display data and reuses it to speed up the loading time of the page.

Performance Display

The execution speed of WordPress and the number of queries appear on the control bar. The background color will change depending on the number. You can switch the plug-in on and off from the settings screen.

Device Switching

Device Switching can change the display theme according to different mobile devices, such as smartphones and tablets, to optimize the display. Even with the cache function enabled, this plug-in can switch themes correctly for each device.

Translation Accelerator

Translation Accelerator can disable the translation of WordPress, plug-ins and themes that support multiple languages, or cache the translation data. This plug-in accelerates the loading of translation data and reduces loading time of pages.

How to use KUSANAGI plug-ins

Click KUSANAGI from the menu on management screen to show “KUSANAGI Settings”. You can configure each plug-in from this screen.

Page Caching settings

Page Caching is disabled by default.

Log in to the virtual machine via SSH, switch to root user, and run the following command to enable cache.

# kusanagi bcache on

1. Cache expiration time
   You can set cache expiration time separately for front page, archives, and articles.
2. Cache URL exceptions
   You can specify URLs that you wish to exclude from caching.
   Cache is disabled below wp-admin directory by default.
3. Query string to cache
   You can specify query strings that cache is enabled.
   WordPress default queries have already been specified in advance, so you don’t have to register them here.
4. Cache to delete when publishing an article
   You can set the scope of cache to be removed at the same time of publishing an article. For example, it is effective when you want to post the latest article on the front page.
5. Clear cache
   You can delete all the cache generated.
   Please note that for high traffic websites, server load may increase temporarily after the cache is cleared.
6. Restoration of advanced-cache.php
   Make sure to click this button to perform the restoration if you want to change the cache starting time or any cache settings listed above in 1 to 4.
