Use the command to check whether there are settings for startup:
chkconfig --list

If there is no memcached in the above display, try to manually add a startup
chkconfig --add memcached chkconfig --level 2345 memcached on

Hello, try to reinstall uninstall WebSite Speed.

zahari.amin

aaPanel_Kern

I'm following your guide and all looks fine. i think this is website speed problem and not sure related to the cache size.

these problems relate to my previous post:
https://www.aapanel.com/forum/d/11898-ah01873-init-session-cache-is-not-configured-hint-sslsessioncache

what is the difference between cache size for Memcached vs website speed? any tips for best configuration?
my server spect is CPU 32 Core(s) and RAM 127297(MB)

Thanks

The lua module of http may not be installed successfully.
Memcached has not started http, and PHP has started, which makes it impossible to connect to Memcached.

aaPanel_Kern

PHP and MySQL can be configured. Optimization can be set to the maximum level. Restart after setting
Http is already highly configured by default

aaPanel_Kern
Thanks your reply..this is my screenshoot.. Optimization already set before..

currently, after the last changes, my error log got improvement and this is my step:

clear cache (memcached & website speed)
uninstal & reinstall website speed
configure Cache and increase size to 4096MB for booth (memcached & website speed)
restart memcache

this is my sc:

this is the error log from yesterday:

I would really appreciate it if you could show me the path for the cache location for Memcached & website speed for troubleshooting purposes

thanks

hello, have you added the mod_heartmonitor module by yourself?
The SSL name of Apache does not match. Can you try to change the ServerName configured at the site to the name you used when you applied for SSL? The universal domain name (*) directly uses the name of the site.
as ServerName www.129test.com

zahari.amin

aaPanel_Kern hi
could you guide me on how to add mod_heartmonitor with best practices?

Thanks
