備份全部數據庫和其數據到對應的文件中

mysqldump最多隻能把全部數據庫輸出到一個sql中,這樣處理起來有點不方便,找了個shell改了下直接把各個庫的數據分開:mysql

#!/bin/bash

USER="username"
PASSWORD="password"

databases=`mysql -u $USER -p$PASSWORD -e "SHOW DATABASES;" | tr -d "| " | grep -v Database`

for db in $databases; do
    if [[ "$db" != "information_schema" ]] && [[ "$db" != "performance_schema" ]] && [[ "$db" != "mysql" ]] && [[ "$db" != _* ]] ; then
        echo "Dumping database: $db"
        mysqldump -u $USER -p$PASSWORD --databases $db > `date +%Y%m%d`.$db.sql
    fi
done

就是這樣了。sql
