Memcache/Memcached settings file

[greektranslator]

I have installed Memcache/Memcached on CentOS 7 following

yum install ea4-experimental
yum install ea-php72-php-memcache
yum install ea-php72-php-memcached

https://features.cpanel.net/topic/memcached-in-easyapache4

And also for php73.
And I wonder where I can find the config files and which settings would be appropriate and if there are different config files for each php version.

You shouldn't need to install the experimental repo for Memcache or Memcached anymore. It's available in the EA4 repo now. You should be able to find the .ini file for Memcached at /opt/cpanel/ea-php72/root/etc/php.d/memcached.ini and /opt/cpanel/ea-php72/root/etc/php.d/memcache.ini

I get this issue when I check its status:

service memcached status

The item size limit by default is noted here 16.2.5Â memcached FAQ how much memory do you have or have you changed this setting?

Defaults are as follows (from my own server running Memcached:

[root@server public_html]# ps faux |grep memcache[d]
memcach+  3846  0.0  0.0 441152  1168 ?        Ssl  May07   0:18 /usr/bin/memcached -u memcached -p 11211 -m 64 -c 1024 -l 127.0.0.1,::1
cpanel-+  4570  0.0  0.0 451220  1204 ?        Sl   May07   0:44  \_ memcached -U 0 -s ./data/Logs/state/memcache.sock

Looks like those specific settings are at:

[root@server public_html]# cat /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1"

So, nothing should be changed at memcached.ini?

In /etc/sysconfig/memcached I have

PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="1GB"
OPTIONS="-l 127.0.0.1,::1"

I changed the "1GB" to 64 and now I get the below. I thought 1GB is a higher value, or not?
