| + | ===== Rendre mysql accessible par le réseau ===== | ||
| + | |||
| + | Par défaut Mysql n'écoute que sur 127.0.0.1. Pour le rendre accessible à d'autres machines, commenter la ligne suivante dans ///etc/mysql/my.cnf// : | ||
| + | bind-address = 127.0.0.1 | ||
| + | |||
| + | ===== Script dump de mysql ===== | ||
| + | Voici un petit script ///home/scripts/export_db.sh// pour exporter l'intégralité des databases mysql dans un fichier (qui sera ensuite à sauvegarder) : | ||
| + | |||
| + | <file> | ||
| + | #/bin/sh | ||
| + | /usr/bin/mysqldump --defaults-file=/etc/mysql/debian.cnf --all-databases --add-drop-database --result-file=/home/scripts/dump_mysql/all_databases.sql | ||
| + | </file> | ||
| + | |||
| + | Ce script utilise le compte de maintenance debian (debian-sys-maint) et exporte les données dans ///home/scripts/dump_mysql/all_databases.sql//. | ||
| + | |||
| + | Pour automatiser l'export, il suffit d'utiliser cron, par exemple en créant ///etc/cron.d/exportdb// : | ||
| + | 55 23 * * * root /home/scripts/export_db.sh | ||
| + | |||
| + | :!: Il est conseillé de protéger l'accès aux données dumpées : | ||
| + | chmod og-rx -R /home/scripts/dump_mysql/ | ||
| + | |||
