Dear All,
I host a Moodle server with 2 nginx servers in load balancing mode, the cache is in the mysql server, the moodle-data is in an NFS server. IF I need to purge cache, do I need to Purge cache for each nginx server one after the other: turning off server A, purging cache for server B, then turning off server B, turning on server A, purging cache for server A, finally turning on server B.
Or I just simply purging cache while both server are on?
Many thanks
