编辑脚本文件[python]

db_user="root"
db_passwd="123456"
db_host="localhost"
backup_dir="/usr/local/apache2/htdocs/backup"
time="$（date +"%Y%m%d%H%M"）"
MYSQL="/usr/local/mysql/bin/mysql"
MYSQLDUMP="/usr/local/mysql/bin/mysqldump"
MKDIR="/bin/mkdir"
RM="/bin/rm"
MV="/bin/mv"
GZIP="/bin/gzip"
test ！ -w $backup_dir && echo "Error: $backup_dir is un-writeable." && exit 0
test ！ -d "$backup_dir/$time" && $MKDIR -p "$backup_dir/$time"
all_db="$（$MYSQL -u $db_user -h $db_host -p$db_passwd -Bse "show databases"）"
for db in $all_db
do
$MYSQLDUMP "--default-character-set=gbk" -u $db_user -h $db_host -p$db_passwd $db | $GZIP -9 > "$backup_dir/$time/$db.gz"
done
exit 0;
