I have memcached running on my server. But phpinfo.info shows that only memcahe is installed.
php -i | grep memcach gives:

@legend said in CWP - memcache, memcached and redis, redis cluster:
chunk
you can find some info here
https://github.com/websupport-sk/pecl-memcache/blob/NON_BLOCKING_IO_php8/README -
@sandeep Thanks for this excellent support.
As from the above, i installed memcached, mecache directly from the cwp. Should I remove them and follow the this https://github.com/websupport-sk/pecl-memcache/blob/NON_BLOCKING_IO_php8/README for php7.3 or php-fpm73?
-
@legend installation is same for cwp too you don;t need to to uninstall anything.
-
@sandeep Thanks. Do you have a tutorial on using memcached as a php session handler or this occur by default after mecached installtion?
-
@legend memcached is installed as php extension and only can be used when you configured memcached with your site's script. If your site doesn't support it then I'm afraid you can't use it anyway.
there is one tutorial for WP in the blog.
-
@sandeep my site supports it. its for magento and whmcs.
i want php to save to seesions to memcached and to files as the default. redis is good as php handler but it has issues with whmcs.
For magento, redis will handle session and page cache while varnish is for full page cache.
-
@legend in php.ini
you can define/add it :session.save_handler = memcached session.save_path = "localhost:11211" -
@sandeep thanks
