    -<note warning>Before installing or upgrading, check your Internet connection. Make shure you run scripts under the root or using sudo.</note> 
    - 
    -<note warning>Check if the time and time zone are set correctly on the server. Correct and restart the server if necessary.</note> 
    - 
    -<note warning>Do not disable the standard firewall-cmd. The installation script uses it for self-configuration.</note> 
    - 
    -<note warning>Do not use the yum update fastor command. Install/update with the script below.</note> 
    - 
    -For automatically installation or upgrading follow these steps: 
    - 
    -  - Execute [[https://vasexperts.ru/install/fastor-rpm_install.sh|fastor-rpm_install.sh]] script. <code> 
    -source <(curl https://vasexperts.ru/install/fastor-rpm_install.sh) 
    -</code> It will cause the installation of the following packages: ipfixreceiver, clickhouse, fastor. All of them will be automatically configured according to the defaults. 
    -  - Restart your ssh terminal. You need to make command aliases available.  
    -  - Run the command <code> fastor-db-scheme </code> The database schema will be updated.  
    -<note important>In some systems, the database starts very slowly (from several minutes to several tens of minutes, especially in systems with long-term data storage) and when updating you may receive an error like **ERROR: while updating DB scheme**\\ 
    -{{:dpi:dpi_components:qoestor:dbcheme_update_err.png?600|}} 
    - 
    -Wait for the database to start. You can check the tail /var/log/clickhouse-server/clickhouse-server.log logs, or simply try to launch the clickhouse-client client - if there is a connection, then the database has started and is ready for connections. 
    - 
    -After starting the database, run the command <code>fastor-db-scheme</code> 
    -</note> 
    -<note important>Do not forget to execute <code>fastor-db-scheme</code> after installation. This insures cases when the schema does not have time to update as a result of a long restart of the database. </note>
