查看连接mysql的ip地址的方法：

1、最直接的办法如下：

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

2、要统计数据库的连接数，我们通常情况下是统计总数，没有细分到每个IP上。现在要监控每个IP的连接数，实现方式如下：

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

3、通过直接执行也可以实现：

#mysql -u root -h127.0.0.1 -e"show processlist\G;"| egrep "Host\:" | awk -F: '{ print $2 }'| sort | uniq -c 
#mysql -u root -h127.0.0.1 --skip-column-names -e"show processlist;"|awk '{print $3}'|awk -F":" '{print $1}'|sort|uniq –c
