Enable and disable the Binary Logs in MySQL for incomplete recovery

Note: For change this effect, we need to restart the MySQL.

Enable the Binary Log
Note: By default it is activated.
1. Check the parameter “log_bin” set in ini configuration file.

# ***** Group Replication Related *****
# Specifies the base name to use for binary log files. With binary logging
# enabled, the server logs all statements that change data to the binary
# log, which is used for backup and replication.
log_bin="KKK"
#expire_logs_days = 2 -- used for expire the logs


2. Check the Status of Binary Logs.

mysql> show variables like '%log_bin%';

| log_bin_basename                | C:\ProgramData\MySQL\MySQL Server 8.0\Data\KKK       |
| log_bin_index                   | C:\ProgramData\MySQL\MySQL Server 8.0\Data\KKK.index |
| log_bin_trust_function_creators | OFF         |
