enabling memcached extension after switching to suExec mode

[guneetnarula]

Until recently, I was not using the suExec mode (lsapi external app) on any of the three virtual hosts on my server. But I recently turned it on for one of them. Things look good except the memcached extension is showing disabled in the wp plugin object cache screen. On the other two vhost websites, memcached is enabled and connection test passes.

Any idea how to get the suExec lsapi app to recognize memcached?

Can you try to set up a phpinfo page and check if Memcached is on it?

 

[guneetnarula]

Yes I checked that. For the vhost with the suExec enabled, it is not. For the other two, memcached is on it.

I was able to enable the service by switching to UDS instead of TCP, but the connection test fails on all vhosts now.

See:

systemctl status lsmcd.service

The first thing is to figure out why there's no Memcached on that domain. Can you also add phpinfo page to other domain and compare if both load the same "Loaded Configuration File"

 

[guneetnarula]

So right now, using phpinfo() on all three sites, I can see that memcached support is enabled. The only problem is that the connection test in litespeed cache plugin on all of them says "failed"

I switched on debug mode, and found this on the bottom of the generated HTML page:
Object Cache [total] 11320 [hit_incall] 10349 [hit] 0 [miss_incall] 400 [miss] 571 [set] 944

Does this mean LSMCD is working as intended?
