  SOCKET=/data/3306/<a style='color:#f60; text-decoration:underline;' href="https://m.php.cn/zt/15713.html" target="_blank">mysql</a>.sock

  MYLOGIN=”mysql -u$MYUSER -p$MYPASS -S $SOCKET”

  MYDUMP=”mysqldump -u$MYUSER -p$MYPASS -S$SOCKET -B”

  DATABASE=”$($MYLOGIN -e “show databases;”|egrep -vi “Data|_schema|mysql”)”

  for dbname in $DATABASE  do  MYDIR=/server/backup/$dbname  [ ! -d $MYDIR ] && mkdir -p $MYDIR  $MYDUMP $dbname|gzip >$MYDIR/${dbname}_$(date +%F).sql.gz

  done
