Uninstall Observium | Ubuntu [repack]

sudo nginx -t sudo systemctl reload nginx

Many installation guides modify the default virtual host ( 000-default.conf ) to point to /opt/observium/html . If you only altered the default configuration, you may want to restore the original file or simply remove the Observium‑specific lines from it.

By following these steps, you can effectively uninstall Observium from your Ubuntu server, ensuring that no traces remain.

Then run these SQL commands:

sudo rm -rf /var/log/observium

Deleting this folder will permanently erase all historical graphing data. Remove the entire installation directory recursively: sudo rm -rf /opt/observium Use code with caution.

Observium stores device metadata, user accounts, and configuration settings in a MySQL or MariaDB database. Log into your database server as the root user: sudo mysql -u root -p Use code with caution. Enter your MySQL root password when prompted.

sudo mysql -uroot -p<password>

By default, Observium installs into the /opt/observium directory. This folder contains the core PHP scripts, the web front-end files, and the RRD files (which hold your historical performance graphs and can take up gigabytes of space). Force-remove the entire directory structure: sudo rm -rf /opt/observium Use code with caution.

sudo rm /etc/apache2/sites-available/observium.conf sudo rm /etc/apache2/sites-enabled/observium.conf Use code with caution.

Next, delete the dedicated database user created during installation. Replace 'observium' with your actual Observium DB username if you customized it: DROP USER 'observium'@'localhost'; Use code with caution. Flush the privileges to apply the changes and exit: FLUSH PRIVILEGES; EXIT; Use code with caution. Step 4: Delete the Observium Installation Files

Check /var/log/syslog or use sudo grep -i "observium" /var/log/syslog over the next few minutes to confirm that no automated cron errors are triggering. Your Ubuntu system is now completely free of Observium. To help you tidy up your server, tell me: sudo nginx -t sudo systemctl reload nginx Many

The standard Observium installation locates all web and application files under /opt/observium . Additionally, it may store logs and RRD (Round Robin Database) files elsewhere.

Before executing any commands, take a moment to prepare your environment. Deleting files and dropping databases are irreversible actions.

Run the following command to permanently delete the entire directory: sudo rm -rf /opt/observium Use code with caution.

During a standard installation, a dedicated system user named observium is often created to run the poller scripts safely without root permissions. Then run these SQL commands: sudo rm -rf

sudo mysql -uroot -p<password>
