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
