How to find MySQL server uptime?
You can use mysqladmin utility to find MySQL server's uptime. Run the following command from command line.
mysqladmin -u<user> -p<password> -h<host name/IP> version
Replace <user> with MySQL username, <password> with password (you can enter invisible password later by using -p only and entering password at the password prompt). The command above not only tells you server's version but also tells you server uptime.
Here is sample output from my server
> mysqladmin -uroot -p -hlocalhost version Enter password: ******** mysqladmin Ver 8.41 Distrib 5.0.84, for Win32 on ia32 Copyright (C) 2000-2006 MySQL AB This software comes with ABSOLUTELY NO WARRANTY.
