First run this

mysql -B -u zabbix -pxxx zabbix -e 'SELECT CONCAT("ALTER TABLE ", TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;") AS ExecuteTheString
FROM information_schema.`COLUMNS`
WHERE table_schema = "zabbix" AND COLLATION_NAME = "utf8_general_ci";'

After that paste command output to another

mysql -B -u zabbix -pxxx zabbix -e '<paste here>'

openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out crt.pem

Notice: key.pem is in private folder, whereas crt.pem is in the certs folder.

To put notice on the margin (not in first column as many does) following latex code can be used:

 \fancyfoot[LO]{978-1-xxxx-xxxx-4/21/\$31.00~\copyright2021 IEEE}
 \renewcommand{\headrulewidth}{0pt} % remove horizontal rule
 }

after \maketitle
