Three Methods to Check Uptime of MySQL/MariaDB Database Server on Linux

We all know the purpose of the uptime command in Linux.

This is used to check the uptime of the Linux system and how long the system runs without restarting.

The Linux admin job is to keep the system up and running.

If you want to check how long other services like Apache, MySQL, MariaDB, sftp, etc., are running on Linux, how do you do that?

Each service has their own command to check the uptime of service.

But you can also use other commands for this purpose.

Method-1: How to Check the Uptime of a MySQL/MariaDB Database Server on Linux Using the ps Command

The ps command stands for process status. This is one of the most basic commands that shows the system running processes with details.

To do so, you first need to find the PID of MySQL/MariaDB using the pidof command.

# pidof mysqld | cut -d" " -f1


Once you have the MySQL/MariaDB PID, use the “etime” option with the ps command and get the uptime.

  • etime: elapsed time since the process was started, in the form of [[DD-]hh:]mm:ss.
# ps -p 2412 -o etime


Alternatively, use the “lstart” option with the ps command to get the uptime of a given PID.

# ps -p 2412 -o lstart

The MySQL/MariaDB process has been running for 2 days, 03 hours, 02 minutes and 15 seconds.

Method-2: How to Check the Uptime of a MySQL/MariaDB Database Server on Linux Using the Systemctl Command

The systemctl command is used to control the systemd system and service manager.

systemd is a new init system and system manager, that was adopted by most of Linux distributions now over the traditional SysVinit manager.

# systemctl status mariadb
# systemctl status mysql

Method-3: How to Check the Uptime of a MySQL/MariaDB Database Server on Linux Using the MySQLAdmin Command

MySQLAdmin is a command-line utility for MySQL Server that is installed when installing the MySQL package.

The MySQLAdmin client allows you to perform some basic administrative functions on the MySQL server.

It is used to create a database, drop a database, set a root password, change the root password, check MySQL status, verify MySQL functionality, monitor mysql processes, and verify the configuration of the server.
