yesterday I have seted up a wordpress "clutser".
- Two Front/Backend Servers for Nginx and PHP
- One Database Server
- on all there is installed memcached
- I have a internal network, so no authenticate problems
My problem is now, to sync the /wp-content/-folder with all the plugins, themes and user-uploads. I have tested two ways: sshfs and unison. Both worked for file syncing... but wordpress never shows a picture?! And normal files (example: pdf) are only showed by one of my backend-servers on the other a 404 is coming.
Maybe someone had a similar problem and can help me.
Is there something else somebody know to secure my three servers?
