Answers to common installation issues

The ESET PROTECT Server service does not start:

Broken installation

•This might be the result of missing registry keys, missing files or invalid file permissions.

•The ESET All-in-one installer has its own log file. When installing a component manually, use the MSI Logging method.

Listening port already used (mostly 2222 and 2223)

Use the appropriate Command for your OS:

•Windows:
netstat -an | find "2222"
netstat -an | find "2223"

•Linux:
netstat | grep 2222
netstat | grep 2223

Database not running / not reachable

•Microsoft SQL Server: Verify that port 1433 is available on/to the database server or try to log in to SQL Server Management Studio.

•MySQL: Verify that port 3306 is available on/to the database server or try to log in to your database interface (for example, using the MySQL command-line interface or phpmyadmin).

Corrupted database

Multiple SQL errors will be shown in the ESET PROTECT Server log file. We recommend that you restore your database from a backup. If a backup is not present, reinstall ESET PROTECT On-Prem.

Insufficient system resources (RAM, disk space)

Review running processes and system performance:

•Windows users: Run and review information in Task Manager or Event Viewer

•Linux users: Run one of the following commands:
df -h (to review disk space information)
cat /proc/meminfo (to review memory space information)
dmesg (to review your Linux system healh)

ESET Management Agent uninstallation troubleshooting
