  65. # Define the variables the script used for executing.

  71. # Call the parse_options function to parse the input arguments.
  72. parse_options "$@"
  73. echo ${HOST}
  74. echo ${USER}
  75. echo ${PASSWORD}
  76. echo ${PORT}

  78. mysql -u${USER} -p${PASSWORD} -h${HOST} -P${PORT} -Ne 'select user,host,password from mysql.user'>./userinfo

  80. #echo "------------ host:${HOST} port:${PORT} checkTime:`date +'%Y-%m-%d %T'`-------------">>./weakPassword.log
  81. cat /root/python/lscj/userinfo|while read line
  82.  do
  83.         userName=`echo $line|awk -F' ' '{print $1}'`
  84.         userHost=`echo $line|awk -F' ' '{print $2}'`
  85.         userPwd=`echo $line|awk -F' ' '{print $3}'`
  86.         echo "userName=$userName,userHost=$userHost,userPwd=$userPwd"
  87.         result=`mysql -uroot -pESBecs00 -Ne "select 1 from test.tb_weak_password where password='$userPwd'"`
  88.                 if [ ! -n "$result" ]
  89.                      then
  90.                         echo "User:${userName}@${userHost} is safe!!">>safe.log
  91.                 else
  92.                         echo "User:${userName}@${userHost} is unsaft!!">>unsafe.log
  93.                 fi
  94.         echo ""
  95.         echo ""
  96. done

test.tb_weak_password是密碼字典！需要自己去生成，透過對比檢查使用者密碼的強弱性

執行結果如下
[root@localhost lscj]# sh checkpass2.sh  --password=ESBecs00
[root@localhost lscj]# more unsafe.log 
User:root@localhost is unsaft!!
User:liang@% is unsaft!!
[root@localhost lscj]# more safe.log 
User:jonn@% is safe!!
User:tom@% is safe!!
User:marry@% is safe!!
User:karry@% is safe!!
