1. mysql--杀掉数据库连接

sql语句如下:

# 展示所有连接
show processlist

# 杀掉睡眠时间大于600s的连接
select concat('KILL ',id,';') from information_schema.`processlist` 
where command = 'Sleep' and time > 600;

# 杀掉发送数据状态的连接
select concat('KILL ',id,';') from information_schema.`processlist` 
where state = 'Sending data';

# 杀掉等待状态的连接
select concat('KILL ',id,';') from information_schema.`processlist` 
where state = 'Waiting for table metadata lock';
