|
||
|
||
rsync -e "ssh -p 22" -arzv host:/path/to/owncloud/config /path/to/backup/owncloud/
|
||
|
||
### [Backup DB][7]

||
|
||
mysqldump --lock-tables -h [server] -u [username] -p[password] [db_name] > owncloud-dbbackup_`date +"%Y%m%d"`.bak

|
||
|
||
### Restore DB
|
||
|
||
[Créer le nouvel user et sa base][8]:
|
||
|
||
CREATE USER 'owncloud'@'localhost' IDENTIFIED BY 'password'
|
||
CREATE DATABASE IF NOT EXISTS owncloud;
|
||
GRANT ALL PRIVILEGES ON owncloud.* TO 'owncloud'@'localhost' IDENTIFIED BY 'password';
|

|
||
imap 10800 IN CNAME access.mail.gandi.net.
|

|
||

|
||
|
||
## Surprises
|
||
|
||
### Changement de Debian/Wheezy -> Debian/Jessie
|
||
|
||
#### Apache2: [v2.2 -> v2.4][9]
|
||
|
||
##### site-avaiable
|
||
Les noms des fichiers se terminent [par .conf][10]
|
||
|
||
##### PhpMyAdmin
|
||
|
||
__Erreur__: `Fatal error: require_once(): Failed opening required '/usr/share/php/php-gettext/gettext.inc' (include_path='.') in /usr/share/phpmyadmin/libraries/select_lang.lib.php on line 463`
|
||
|
||
__Remède__: Ajout de _/usr/share/php/php-gettext/_ dans la directive _php_admin_value open_basedir_ du fichier de conf apache. (_Ref. : [phpmyadmin symlinks error after ubuntu upgrade - superuser.com][10]_)
|
||
|
||
##### Owncloud logging
|
||
|
||
(Re)mettre en place les logs dans [_/var/log/owncloud/_ et le logrotate][11]
|
||
|
||
##### Manipulation des données ownCloud en local via CLI
|
||
|
||
Mise en place de [davfs2][14] pour le montage via _fstab_. Attention [doc.owncloud][13] est incomplète, voir aussi la [doc.ubuntu][12]
|
||
|
||
__erreur__: /sbin/mount.davfs: warning: the server does not support locks
|
||
|
||
/etc/fstab
|
||
|
||
~/.davfs2/secrets
|
||
|
||
/etc/davfs2/cert
|
||
|
||
/etc/davfs2/davfs2.conf
