看到此./mysql_test腳本在運行，find / -name mysql_test

[root@db-m1-slave-1 ~]# find / -name mysql_test
/usr/local/mysql/test/mysql_test
[root@db-m1-slave-1 ~]#

[root@db-m1-slave-1 test]# more mysql_test
******** mysql_test: Not a text file ********

查詢到此mysql_test是使用了一個mysql的用戶信息收集的插件，，上傳到mysql官網了,是個軟件運行信息反饋的那種功能。
只要kill掉就沒事了。
