Post Install Steps​

Recommended steps after installing OpenPanel:

• access admin panel
• set domain for accessing panels
• set custom nameservers
• create a hosting plan
• create a new user account
• set admin email for server alerts

Access OpenAdmin​

Run opencli admin command to find the address on which admin panel is accessible. Example output:

root@server:/home# opencli admin
● AdminPanel is running and is available on: https://server.openpanel.co:2087/

To login to admin panel you need a username and password.

Both username and password are random generated on installation.

To view admin accounts:

opencli admin list

To set a new password for the admin account run command: opencli admin password USER_HERE NEW_PASSWORD_HERE

Example:

root@server:/home# opencli admin password stefan ba63vfav7fq36vas
Password for user 'stefan' changed.

Enable Automatic Updates​

• autopatch option allows Administrator to automatically update OpenPanel to minor versions. MINOR versions include only security updates and bug fixes.
• autoupdate option allows Aministrator to enable or disable automatic updates to major versions. MAJOR versions add new functionality in a backward compatible manner.

opencli config update autoupdate yes

opencli config update autopatch yes

Disable Automatic Updates​

opencli config update autoupdate no

opencli config update autopatch no

Manual Updates​

When a new update is available, you will receive a notification in the admin panel.

• With OpenAdmin
• With OpenCLI

To manually update OpenPanel, navigate to OpenAdmin > General Settings and click on the "Update Now" button. NOTE: update is visible only if newer version is available.

License​

OpenPanel is available in two editions:

• OpenPanel Community edition is a free version of the panel that is limited to 3 user accounts and 50 domains, which should be more than enough for personal use.
• OpenPanel Enterprise edition unlocks premium features for user isolation and management, suitable for web hosting providers. It has API access and can easily be integrated with 3rd party billing tools like WHMCS and FOSSBilling.

OpenPanel Community VS Enterprise

Security​

OpenPanel has been built from the ground up with security in mind. Internet history is littered with painful security incidents, so we traded old software compatibility and insecure authentication methods for modern day security measures.

Firewall​

OpenPanel supports both ConfigServer & Firewall (CSF) and UncomplicatedFirewall (UFW).

Isolated Services​

Each user is provided with a containerized environment similar to a VPS, featuring their own web server (Nginx or Apache) and database (MySQL or MariaDB). This setup prevents resource hogging commonly associated with standard shared hosting.

Two-Factor Authentication​

Users have the option to enable Two-Factor Authentication (2FA) for added security on their accounts. Administrators can manage this feature at the server level or for individual users.

Detailed Logging​

All actions taken by OpenPanel users are recorded in per-user activity logs. This eliminates confusion over issues like file or webmail account deletions—every action is logged and can be reviewed by users.

Isolated Users and Admin​

OpenPanel and OpenAdmin operate independently from one another. One runs as a systemd service while the other runs as a Docker container. OpenPanel utilizes SQLite for its database, whereas OpenAdmin relies on MySQL. Importantly, users can perform actions on their panel even if the admin panel is unreachable or disabled.

Disabling the Admin Panel​

For production environments, particularly with the Community edition—which does not offer API access and lacks third-party integrations—it is advisable to disable the admin panel after configuring your server. Alternatively, you can restrict access to the admin port 2087 by whitelisting your team's IP addresses.

To disable OpenAdmin, navigate to OpenAdmin > Settings > OpenAdmin and click on "Disable Admin Panel" or use the terminal command opencli admin off. This will deactivate the admin panel, and you can re-enable it when necessary with the command opencli admin on.

Limiting Access to Admin Panel​

To restrict OpenAdmin access to your team, whitelist your server's IP addresses in CSF/UFW, and then disable port 2087.

HTTP Basic Authentication​

As an additional security measure, HTTP Basic Authentication can be enabled for the admin panel.

Brute-Force Protection​

Both user and admin interfaces have a built-in rate limiting and IP address blocking to protect against brute-force attacks. You can configure the maximum number of failed login attempts allowed per IP (default is 5 per minute) and the total number of failed attempts (default is 20), after which the offending IP will be temporarily blocked by the firewall for one hour.

For user panel imits are configurable in: /etc/openpanel/openpanel/conf/openpanel.config file:

[USERS]
login_ratelimit=5
login_blocklimit=20

For admin panel imits are configurable in: /etc/openpanel/openadmin/config/admin.ini file:

[PANEL]
login_ratelimit=5
login_blocklimit=20

If a user successfully logs in, the counter for login_blocklimit will reset. Failed login attempts and blocked IP addresses are logged in the /var/log/openpanel/admin/failed_login.log file for OpenAdmin and in the /var/log/openpanel/user/failed_login.log file for OpenPanel.

IP blocking per domain​

Users can block IP addresses per domain name.
