多執行個體MySQL大量新增使用者和密碼並授權

標籤：

OS:Cent OS 6.3

DB:5.5.14

如果一台伺服器上有100個MySQL資料庫執行個體，此時需要給不同連接埠的幾個資料庫添加使用者名稱、密碼並授權應用IP，一個個授權沒問題，反正累的不是我，哇哢哢。


建立add_user.sh

#/bin/bash
#add user to mysql db


passpwd="yoon"


cat user.txt | while read user
do
  port=`echo $user |awk ‘{print $1 }‘`
  username=`echo $user |awk ‘{print $2 }‘`
  pwd=`echo $user |awk ‘{print $3 }‘`
  db=`echo $user |awk ‘{print $4 }‘`
#  echo ‘port=‘$port‘;username=‘$username‘;pwd=‘$pwd‘;db=‘$db


  /export/servers/mysql/bin/mysql -S /export/data/mysql/tmp/mysql$port.sock -uroot -p$passpwd <<EOF


use mysql;


GRANT  SELECT,INSERT,UPDATE,DELETE ON $db.* TO ‘$username‘@‘192.17.12.2‘ IDENTIFIED BY ‘$pwd‘;
GRANT  SELECT,INSERT,UPDATE,DELETE ON $db.* TO ‘$username‘@‘192.17.12.3‘ IDENTIFIED BY ‘$pwd‘;
GRANT  SELECT,INSERT,UPDATE,DELETE ON $db.* TO ‘$username‘@‘192.17.12.4‘ IDENTIFIED BY ‘$pwd‘;


flush privileges;


EOF



done
