接到业务需求,要我统计哪个应用访问了哪些表,一般来讲可以通过:
1.show full processlist;
2.SELECT HOST FROM information_schema.processlist where user='dbname' and INFO like '%tbname%'"
上述两种方法都可以,但是第一种不方便统计,为此我选用了第二种方法:
#!/bin/bash
COUNTER=0
tmp_file=$1
while [ $COUNTER -lt 10000 ];
do
ss=`mysql -uroot -N -e"SELECT HOST FROM information_schema.processlist where user='dbname' and INFO like '%tbname%'";`
echo $ss>>${tmp_file}
let COUNTER=COUNTER+1
done
然后
awk -F":" '{print $1}' ${tmp_file}| sort | uniq
就可以找出访问表的ip了
