看到此./mysql_test脚本在运行,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 ********

查询到此mysql_test是使用了一个mysql的用户信息收集的插件,,上传到mysql官网了,是个软件运行信息反馈的那种功能。
只要kill掉就没事了。
