Mysql查看用戶連接數配置及每個IP的請求情況

1、查看當前數據庫的連接情況

    show full processlist;

    show processlist;

2、查看所有用戶的總連接數

  show variables like '%max_connections%';

3、查看每一個用戶的最大連接數

show variables like '%max_user_connections%';

4、查看當前連接中各個用戶的連接數

select USER , count(*) from information_schema.processlist group by USER;

5、查看當前連接中各個IP的連接數

select SUBSTRING_INDEX(host,':',1) as ip , count(*) from information_schema.processlist group by ip;

6、查看當前連接中連接時間最長的的連接

 select host,user,time,state,info from information_schema.processlist order by time desc limit 10;

7、查詢線上Mysql數據庫的連接數配置

show variables like '%conn%';
