MySQL提示:too many connections
1.首先查询最大连接数
show variables like '%max_connections%';
2.检查当前的连接情况:
show processlist;
3.批量kill当前的连接:
通过information_schema.processlist表中的连接信息生成需要处理掉的MySQL连接的语句临时文件,然后执行临时文件中生成的指令
获取当前连接的id:
select concat('KILL ',id,';') from information_schema.processlist where user='yxyq';
转存到文件中:
select concat('KILL ',id,';') from information_schema.processlist where user='yxyq' into outfile 'D:/BCSoftware/mysql-8.0.13-winx64/a.txt';
执行文件:
source D:/BCSoftware/mysql-8.0.13-winx64/a.txt;
