This section describes how to use MySQL admin tool to check server status and other admin tasks.
If you want to know whether your MySQL server is alive, you can use the "mysqladmin"
program in a command window as shown in the following tutorial:
C:\>\local\mysql\bin\mysqladmin -u root ping
mysqld is alive
The "mysqld is alive" message tells you that your MySQL server is running ok.
If your MySQL server is not running, you will get a "connect ... failed" message.
You can also use "mysqladmin" program to check version number of your MySQL server
in a command window as shown in the following tutorial:
C:\>\local\mysql\bin\mysqladmin -u root version
\local\mysql\bin\mysqladmin Ver 8.42 Distrib 5.5.15, for Win32 on x86
