FAQ

Important Ìtumọ̀ Yorùbá: – Please refer to https://github.com/rtcamp/nginx-helper#frequently-asked-questions for up-to-date FAQs.

FAQ Ìtumọ̀ Yorùbá: – Installation/Comptability

Q. Will this work out of the box?

No. You need to make some changes at the Nginx end. Please check our tutorial list.

FAQ Ìtumọ̀ Yorùbá: – Nginx Fastcgi Cache Purge

Q. ThereÌtumọ̀ Yorùbá: ’s a ‘purge all’ button? Does it purge the whole site?

Yes, it does. It physically empties the cache directory. It is set by default to /var/run/nginx-cache/.

If your cache directory is different, you can override this in your wp-config.php by adding
define(‘RT_WP_NGINX_HELPER_CACHE_PATH’,Ìtumọ̀ Yorùbá: ’/var/run/nginx-cache/’);

Replace the path with your own.

Q. Does it work for custom posts and taxonomies?

Yes. It handles all post-types the same way.

Q. How do I know my Nginx config is correct for fastcgi purging?

Manually purging any page from the cache, by following instructions in the previous answer.

Version 1.3.4 onwards, Nginx Helper adds a comment at the end of the HTML source (‘view source’ in your favourite browser):
<!Ìtumọ̀ Yorùbá: –Cached using Nginx-Helper on 2012-10-08 07:01:45. It took 42 queries executed in 0.280 seconds.Ìtumọ̀ Yorùbá: –>. This shows the time when the page was last cached. This date/time will be reset whenever this page is purged and refreshed in the cache. Just check this comment before and after a manual purge.

As long as you donÌtumọ̀ Yorùbá: ’t purge the page (or make changes that purge it from the cache), the timestamp will remain as is, even if you keep refreshing the page. This means the page was served from the cache and itÌtumọ̀ Yorùbá: ’s working!

The rest shows you the database queries and time saved on loading this page. (This would have been the additional resource load, if you werenÌtumọ̀ Yorùbá: ’t using fast-cgi-cache.)

Q. I need to flush a cached page immediately! How do I do that?

Nginx helper plugin handles usual scenarios, when a page in the cache will need purging. For example, when a post is edited or a comment is approved on a post.

To purge a page immediately, follow these instructions:

  • LetÌtumọ̀ Yorùbá: ’s say we have a page at the following domain: http://yoursite.com/about.
  • Between the domain name and the rest of the URL, insert ‘/purge/’.
  • So, in the above example, the purge URL will be http://yoursite.com/purge/about.
  • Just open this in a browser and the page will be purged instantly.
  • Needless to say, this wonÌtumọ̀ Yorùbá: ’t work, if you have a page or taxonomy called ‘purge’.

Q. Does it need any kind of URL structure?

Yes. When setting the URL structure in Nginx configuration file a trailing slash should always be added.

FAQ Ìtumọ̀ Yorùbá: – Nginx Redis Cache

Q. Can I override the redis hostname, port and prefix?

Yes, you can force override the redis hostname, port or prefix by defining constant in wp-config.php. For example:

`

define(‘RT_WP_NGINX_HELPER_REDIS_HOSTNAME’, ‘10.0.0.1’);

define(‘RT_WP_NGINX_HELPER_REDIS_PORT’, ‘6000’);

define(‘RT_WP_NGINX_HELPER_REDIS_PREFIX’, ‘page-cache:’);
`

Q. Can I override the redis socket path, username, password?

Yes, you can force override the redis socket path, username, password by defining constant in wp-config.php. For example:

`php

define( ‘RT_WP_NGINX_HELPER_REDIS_UNIX_SOCKET’, ‘/var/run/redis/redis.sock’ );

define( ‘RT_WP_NGINX_HELPER_REDIS_USERNAME’, ‘admin’ );

define( ‘RT_WP_NGINX_HELPER_REDIS_PASSWORD’, ‘admin’ );
`

FAQ Ìtumọ̀ Yorùbá: – Nginx Map

Q. My multisite already uses WPMU_ACCEL_REDIRECT. Do I still need Nginx Map?

Definitely. WPMU_ACCEL_REDIRECT reduces the load on PHP, but it still ask WordPress i.e. PHP/MySQL to do some work for static files e.g. images in your post. Nginx map lets nginx handle files on its own bypassing wordpress which gives you much better performance without using a CDN.

Q. I am using X plugin. Will it work on Nginx?

Most likely yes. A wordpress plugin, if not using explicitly any Apache-only mod, should work on Nginx. Some plugin may need some extra work.

FAQ Ìtumọ̀ Yorùbá: – WP-CLI

Q. How can I update the options using WP-CLI?

`shell

wp option patch update rt_wp_nginx_helper_options
`

Still need help!

Please post your problem in our free support forum.

Works well 🙂

Clears cache when updating pages & posts as expected. Also great that it has a logging functionality, which allowed me to debug some problems.

Work like a charm

Nice plugin to manage your cache. The setup is quite simple! Just follow the instructions and you will be fine

Unusable

Had high hopes but to be able to use this plugin to best potential you need to add a repository, according to the relevant guide which seems to date back 9 years. Errors:- E: The repository ‘http://ppa.launchpad.net/rtcamp/nginx/ubuntu focal Release’ does not have a Release file. N: Updating from such a repository canÌtumọ̀ Yorùbá: ’t be done securely, and is therefore disabled by default. So whatÌtumọ̀ Yorùbá: ’s the point? I may be missing something (such as a guide that works? Am using your recommendation: https://easyengine.io/wordpress-nginx/tutorials/single-site/fastcgi-cache-with-purging/) so sort that out, let me know, and IÌtumọ̀ Yorùbá: ’ll gladly update this review. Meantime, damn, that was a few hours wasted.
