To work, you will need SSH access to the root server. Installation will be carried out in console mode through terminal commands. If you need to execute a sudo command to obtain root privileges, you must execute a command before installing:<\/p>\n\n\n\n
sudo su -<\/pre>\n\n\n\n
Installation of necessary packages and libraries<\/h2>\n\n\n\n
We establish dependencies with the help of \u00a0apt:<\/p>\n\n\n\n
Be careful - you need to use the Smarty Lite installation package specifically for the Debian Bookworm version, it is located in the bookworm directory. Otherwise, an error may occur when performing further commands undefined symbol: PyFPE_jbuf<\/em>.<\/p>\n\n\n\n
Installation of DBMS for Smarty Lite<\/h2>\n\n\n\n
Smarty Lite supports various databases, in the basic version it is recommended to use MySQL or MariaDB, for Debian Bullseye we install MariaDB:<\/p>\n\n\n\n
apt install mariadb-server<\/pre>\n\n\n\n
Create a user to connect Smarty Lite in the database and specify the password in the Smarty Lite settings:<\/p>\n\n\n\n
export DBPASSWORD='pwgen -s 16 1'\necho \"CREATE DATABASE smarty CHARACTER SET = utf8;\" | mysql -u root\necho \"SET default_storage_engine=InnoDB;\" | mysql -u root\necho \"CREATE USER 'smarty'@\"%<\/code>' IDENTIFIED BY '$DBPASSWORD';' | mysql -u root\necho \"GRANT ALL PRIVILEGES ON smarty.* To 'smarty'@\"%<\/code>';' | mysql -u root\necho \"FLUSH PRIVILEGES;\" | mysql -u root\nsed -i -e 's\/PUT DB PASSWORD HERE\/'$DBPASSWORD'''\/g' \/etc\/microimpuls\/smarty-lite\/smarty-lite.py<\/pre>\n\n\n\n
The last command replaces the string \u00abPUT DB PASSWORD HERE\u00bb with the automatically generated password in the file \/etc\/microimpuls\/smarty-lite\/smarty-lite.py<\/code> (Smarty Lite settings file).<\/p>\n\n\n\n
The Smarty Lite settings file defaults the connection settings to the locally installed MySQL-compatible DBMS (in this example, MariaDB), but you can install the DBMS on another machine if necessary.<\/p>\n\n\n\n
Preparation of the configuration of the nginx Web server and the uWSGI application server<\/h2>\n\n\n\n
Prescribe a secret key for the operation of internal protection mechanisms Smarty Lite:<\/p>\n\n\n\n
Next, you need to register the license key. <\/p>\n\n\n\n
To obtain the license key, you need to use the HW key & #8212; the print of the machine on which the Smarty Lite is installed. To obtain it, you need to run uWSGI:<\/p>\n\n\n\n
\/etc\/init.d\/uwsgi restart<\/pre>\n\n\n\n
With each uWSGI restart, be sure to make sure that the old uWSGI processes are killed (you can see using the uWSGI process) ps aux | grep uwsgi<\/code> and pay attention to processes with earlier start times and kill them with kill -9<\/code> where appropriate).<\/p>\n\n\n\n
And then in the file \/var\/log\/uwsgi\/app\/smarty-lite.log<\/code> find the HW key value or use the command:<\/p>\n\n\n\n
This value must be inserted into the appropriate field in the license generation window in the operator\u2019s personal account, and then copy the resulting key with all license parameters that must be written into the configuration file \/etc\/microimpuls\/smarty-lite\/smarty-lite.py<\/code>.<\/p>\n\n\n\n
License generation is called by the button \u00abGenerate a new license key \u00bb in the corresponding product in the LC.<\/p>\n\n\n\n
Copying the license and all parameters is done using the icon \u00abCopy\u00bb in the line with the license key.<\/p>\n\n\n\n
After adding the license configuration, you need to check that it is valid. To do this, you need to restart uWSGI and check the logs for no license errors and no Traceback logs due to the lack of additional python libraries.<\/p>\n\n\n\n
\/etc\/init.d\/uwsgi restart<\/pre>\n\n\n\n
Be sure to make sure old uWSGI processes are killed.<\/p>\n\n\n\n
Checking the logs:<\/p>\n\n\n\n
tail -n 1000 \/var\/log\/uwsgi\/app\/*.log | grep \"*** Starting\" -A 100<\/pre>\n\n\n\n
The last run log must be error free \u00abKey Incorrect\u00bb and \u00abTraceback\u00bb.<\/p>\n\n\n\n
Installation of the OBD scheme<\/h2>\n\n\n\n
We will install the Smarty Lite database schema using the built-in data migration mechanism:<\/p>\n\n\n\n
smarty_manage migrate<\/pre>\n\n\n\n
Launch of services<\/h2>\n\n\n\n
Restart\u00a0nginx\u00a0and\u00a0uWSGI\u00a0with current settings:<\/p>\n\n\n\n
Be sure to make sure old uWSGI processes are killed.<\/p>\n\n\n\n
System settings and configuration example<\/h2>\n\n\n\n
To quickly start using Smarty Lite, we have prepared a team that will set system settings and create examples of data: a set of channels, EPG, tariffs, streaming services and other objects necessary for the operation of the IPTV & OTT service. To do this, do:<\/p>\n\n\n\n
smarty_manage setup_initial_data<\/pre>\n\n\n\n
Then you can edit them and add your data.<\/p>\n\n\n\n
Set up regular commands in crontab<\/h2>\n\n\n\n
For the correct operation of Smarty Lite and updating subscriber data, you need to configure the execution of commands on a schedule in crontab, for this at the end of the file \/etc\/crontab<\/code> add the following lines:<\/p>\n\n\n\n
The first team updates the cache of TV channels. The second command imports EPG (teleguide) 3 times a day: at 5:00, 9:00 and 13:00 server time. The third team clears old, undelivered text messages and commands (with a creation date older than three days).<\/p>\n\n\n\n
Creating a user and getting started<\/h2>\n\n\n\n
IPTV & OTT service in Smarty Lite is managed through the Web-control panel.<\/p>\n\n\n\n
Next, create a user with superadministrator rights to access the control panel:<\/p>\n\n\n\n
The last command will output the generated password, save it.<\/p>\n\n\n\n
For the correct display of pictures \/ styles in Django-adminka, it is necessary to correct in the catalog \/etc\/nginx\/sites-enabled\/smarty*<\/strong> packageway django<\/code> current version python<\/code>. For this, it is necessary to update the ways for the following: location<\/code>:<\/p>\n\n\n\n
For the prescribed python<\/code> version 3.11.2 (check version) python<\/code> team python --version<\/code>) alias should indicate a new version instead of 2.7 \u2014 3.11. For this, you need to prescribe:<\/p>\n\n\n\n
sudo sed -i -e 's\/python2.7\/python3.11\/g' \/etc\/nginx\/sites-available\/smarty*<\/pre>\n\n\n\n
\nAuthorization screen in Smarty Lite<\/figcaption><\/figure>\n<\/div>\n\n\n
Next, you need to install and configure the subscriber portal, connecting it with the Smarty Lite API. Through the portal, the subscriber gets access to IPTV & OTT services.<\/p>\n\n\n\n
After installing the portal, remember to replace the location srv1 portal configuration with mw1 and then reload the nginx configuration:<\/p>\n\n\n\n
