Archived: mysqladmin - MySQL 5.0 Admin Tool

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:

herong> cd \local\mysql\bin
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:

herong> cd \local\mysql\bin
C:\local\mysql\bin>mysqladmin -u root version
\local\mysql\bin\mysqladmin Ver 8.41 Distrib 5.0.45, for Win32 on ia32

Server version          5.0.45-community-nt
Protocol version        10
Connection              localhost via TCP/IP
TCP port                3306
Uptime:                 10 min 38 sec

Threads: 1  Questions: 2  Slow queries: 0  Opens: 12  Flush tables: 1

The output in the above example tells you that the version number is 5.0.45.

If you want to know what else you can do with "mysqladmin", you should run the "-?" option:

herong> cd \local\mysql\bin
C:\local\mysql\bin>mysqladmin -?
