Use mysql5.5 's binlog Times Unknown system variable 'binlog_checksum'

specific error is

-sharp1193 - Unknown system variable "binlog_checksum"

find out that binlog_checksum only appears in the version above mysql5.6.2 and binlog_checksum=none when it is lower than the following version, but when querying, MYSQL indicates that this system variable is unknown. Try to add binlog_checksum=none to My.cnf. When you restart the mysql service, you will also find the error Unknown system variable "binlog_checksum" in the log and Mysql cannot be started. Start normally after removal.

how to solve this problem without modifying the mysql version
PS: because this Mysql is useful to many things, for fear of affecting other projects, the version cannot be modified

binlog_checksum was introduced by MySQL 5.6.2. Since 5.5 doesn't have this parameter at all, you just don't have to add it. Even if you want to, you can't add it. What else do you need to solve?
get is out of your mind for the time being.
