How do I check the ip address that connects to mysql? This problem may be often seen in our daily study or work. I hope you can gain a lot from this question. The following is the reference content that the editor brings to you, let's take a look at it!

The way to see the ip address connected to the mysql is to query directly. The syntax is [select SUBSTRING_INDEX (host,':',1) as ip, count (*) from information_schema.processlist].

How to view the ip address of the connection to mysql:

1. The most direct approach is as follows:

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

2. To count the number of connections to the database, we usually count the total and are not subdivided into each IP. Now you want to monitor the number of connections per IP, as follows:

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

3. It can also be achieved through direct execution:

# mysql-u root-h227.0.0.1-e "show processlist\ G;" | egrep "Host\:" | awk-F:'{print $2}'| sort | uniq-c # mysql-u root-h227.0.0.1-- skip-column-names-e "show processlist;" | awk'{print $3}'| awk-F ":"'{print $1}'| sort | uniq-c
