OR mysqldump [OPTIONS] --all-databases [OPTIONS]
2. mysqldump 備份全庫
備份全庫至/backup/fullbackup.sql
root@chenwx-VirtualBox:/backup# mysqldump --all-databases > /backup/fullbackup.sql
說明：
--all-databases：轉儲所有資料庫
>：指定輸出
/backup/：路徑
fullbackup.sql：備份檔案
3. mysqldump 備份test 、test2資料庫
root@chenwx-VirtualBox:/backup# mysqldump --databases test test2>/backup/backuptest.sql
--database：轉儲指定資料庫多個資料庫用空格分隔
檢視備份資訊
root@chenwx-VirtualBox:/backup# cat backuptest.sql
