[SUCCESS] If there were no errors above, Virtualmin should be ready [SUCCESS] to configure at https://vmi696121.contaboserver.net:10000 (or https://185.182.9.61:10000). [SUCCESS] You'll receive a security warning in your browser on your first visit. Now, you can login to Virtualmin web hosting control panel at https://hosting.turritopsis-dohrnii-teo-en-ming.com:10000/ Post-Installation Wizard ========================= Introduction ============ This post-installation wizard allows you to configure Virtualmin optimally for your system. You can make selections depending on whether you want to host websites, email or databases, and based on your system's memory and CPU power. To continue, click the Next button below. To skip it and use the default settings, click Cancel. Click Next. Memory use ========== Virtualmin can be tuned to improve performance in its user interface and email processing, but at the cost of increased memory use. The best choice depends on how your system will be used. Preload Virtualmin libraries? Choose Yes (more RAM used, faster Virtualmin UI - approximately 40M) Run email domain lookup server? Choose Yes (more RAM used, faster mail processing - approximately 70M) Click Next. If your system is going to host domains that will receive a large amount of email, scanning incoming messages for viruses can generate high CPU load. Because scanning is done using the ClamAV scanning server clamd, it will consume RAM even when not processing email. If your system will not be hosting email, virus scanning can be disabled. Enable virus scanning with ClamAV? Choose Yes (uses approximately 750 MB RAM) Click Next. Error ====== Systemd service clamd@scan cannot be created unless a command is given Resolution to above Error ========================== Enable virus scanning with ClamAV? Choose Keep using on-demand scanner Click Next. Spam filtering ============== If your system is going to host domains that will receive a large amount of email, filtering incoming messages for spam can generate significant CPU load. This is due to CPU use by the SpamAssassin mail filter when it is started, which can be avoided by running the SpamAssassin filter server spamd in the background. This consumes RAM, but reduces CPU load and makes mail processing faster. Run SpamAssassin server filter? Choose Yes (more RAM used, faster mail processing, no per-domain settings - approximately 30M) Click Next. Database servers ================ Virtualmin supports both the MariaDB and PostgreSQL database servers, but you might want to run only one (or neither) on your system. Each consumes RAM when running, even if they are not being used. Depending on the websites and applications you plan to host, running MariaDB only may be enough, as most web applications do not support or require PostgreSQL. If your system will only be used for mail or DNS hosting, there is no need to run either. Run MariaDB database server? Choose Yes (more RAM used, needed for most non-static websites) Run PostgreSQL database server? Choose No (less RAM used) Click Next. MariaDB password ================= To prevent other users on your system from managing the MariaDB database, a password for the root user should be set. Currently the MariaDB password is not set, which is highly insecure. Set MariaDB password: <REMOVED> Remove test MariaDB database? Yes Remove anonymous MariaDB user? Yes Click Next. Error ====== DBI connect failed : Access denied for user 'root'@'localhost' (using password: NO) MariaDB database size ===================== MariaDB can be configured to trade off memory use for performance, depending on how much RAM your system has and how heavily you expect the database to be used. MariaDB configuration size: Choose Huge system (2G or more) on which MariaDB is heavily used (RECOMMENDED) Click Next. DNS configuration ================== For DNS zones created by Virtualmin to be resolvable, the primary nameserver record for each zone must be set to something that can itself be resolved by other systems on the Internet. Primary nameserver: vmi696121.contaboserver.net Uncheck Skip check for resolvability Secondary nameservers (optional): Click Next. Password storage ================ Virtualmin gives you the option of storing plain-text passwords for virtual servers and mailboxes, or storing only one-way encrypted (hashed) passwords. Plain text passwords are more convenient, but less secure if your system is compromised. Password storage mode: Choose Only store hashed passwords Warning - when hashed passwords are used, password recovery for virtual servers will no longer be possible. In addition, the MariaDB password for new servers will be different from the administration password, and will be randomly generated. Click Next. Virtualmin can create a default virtual server that will serve web requests to your system that don't match any other domain. It can also be used to request a Let's Encrypt SSL certificate for use by Virtualmin's own UI. Setup default virtual server? Choose No, thanks Enable SSL on default server? No Click Next. All done ========= Virtualmin post-installation configuration is now complete! Click Next. Virtualmin Virtual Servers =========================== Version 6.17, master admin mode Virtualmin's configuration has not been checked since it was last updated.
