# mac如何开启mysql bin-log
`vim /usr/local/etc/my.cnf `添加以下配置

```shell
expire_logs_days = 5 定期清理
log-bin = /usr/local/var/mysql/mysql_bin_log/mysql-bin #开启binlog,指定文件闻之
server_id = 1 #配置mysql replication需要定义，不能和canal的slaveId重复
binlog_format=MIXEDD
```

`mysql.server restart` // 重启mysql

`show variables like '%log_bin%` 查看是否开启

`show master status; `查看日志状态

`flush logs;` 刷新日志，刷新之后会新建一个新的Binlog日志

`reset master` 清空目录下所有日志文件

查看日志文件：`mysqlbinlog --base64-output=DECODE-ROWS -v mysql-bin.000001`
