Hello,
I have a this multi-server configuration :
- 1 reverse proxy apache (load balancing)
- 2 workers (same instance of owncloud)
- 1 database
- 1 NFS server plugged in a 10To LUN.
Here is how I make my updates (I did the 7.0.4 yesterday) :
In my 1st worker :
Into the /var/www folder, I have a "php" symbolic link for the folder
owncloud-7.0.3 (which is running before update) :
- I download the 7.0.4 owncloud folder ;
- I make my patches into this 7.0.4 folder ;
- I copy the config.php file and the "theme" directory from 7.0.3 folder to
7.0.4 folder ;
- I copy my newly added apps folders from 7.0.3 to 7.0.4.
When I'm ready :
- I cut accesses (reverse proxy) for everyone except my IP address ;
- I make a mysqldump ;
- I change the symbolic link ("php") from 7.0.3 to 7.0.4 folder ;
- I update the DB : /usr/bin/php php/console.php upgrade (this operation sets
automatically owncloud in maintenance mode on and off) ;
- I make a rsync (of my all /var/www) from my 1st worker to my 2nd worker ;
- I make some tests with my account ;
- I open the reverse proxy again.
Offline time : 3-4 minutes depending of my tests.
I don't know if it the best way but I use this method for all our biggest web
applications (moodle, uportal, etc.) and we never had any problem.
The advantage of the symbolic link + mysqldump is that I can revert back to the
previous version easily if something is broken.
If you have any question about my configuration, fell free to ask.
Regards,
