I have made according to the documentation steps:
ERROR:
nginx: [emerg] "fastcgi_cache" zone "WORDPRESS" is unknown in /www/server/nginx/conf/nginx.conf:88
nginx: configuration file /www/server/nginx/conf/nginx.conf test failed
After adding the entry bellow #SSL END the microcaching.
I would like to see something like Engintron has made for cpanel, simple/ fast and reliable.
Another good thing to look into for WP:

Every time I post a new post, my website goes offline?
anyway I fix it after only unchecking everything else except "when a post is published".
should Cloudflare be disabled? or any settings should be done in Cloudflare please?
@aaPanel_Jose - Hi Jose - I am really struggling with enabling caching on my ngnix lemp stack.
Every time i apply these setting it simply crashes my server - do we have any simple documentation for that - I am also willing to pay for support 
PHP Version - 7.3
Ngnix 1.17
AA Panel - 6.7.7
JAY Thanks a lot for your prompt response - Do we have ha ve any documentation to configure OLS or LS Cache ? I really appreciate your help.
JAY Also i am using WordPress websites!
It worked for me as you described in your screenshots but when trying to purge cache, I don't see that files on /dev/shm/fastcgi-cache are deleted and I have to delete them manually, any way to fix this please?
does it work for php 7.4?
dbot yes it works, you have to replace from 73 to 74 in above examples.
After removing the config file from existing setup page is broken.
I had a problem with that solution because while purging cache the files won't to be deleted.
kamil make sure nginx has permissions over the location.
kamil
I commented on this line in user.ini file and purging cache the files work fine
; open_basedir=/www/wwwroot/example.com/:/tmp/:/dev/shm/fastcgi-cache/
