| log_bin | OFF |
| log_bin_basename | |
| log_bin_index | |
| log_bin_trust_function_creators | OFF |
| log_bin_use_v1_row_events | OFF |
| sql_log_bin | ON |

6 rows in set (0.00 sec)
log_bin狀態未開啟

修改mysql配置文件my.cnf
添加如下兩行：

log-bin=/var/lib/mysql/mysql-bin
保存並退出
3、重起mysql 服務
systemctl restart mysqld.service
4、登陸MySql並查看
mysql> show variables like '%log_bin%';

+---------------------------------+--------------------------------+
| log_bin | ON |
| log_bin_basename | /var/lib/mysql/mysql-bin |
| log_bin_index | /var/lib/mysql/mysql-bin.index |
| log_bin_trust_function_creators | OFF |
| log_bin_use_v1_row_events | OFF |
