1、我的mysql是用brew install mysql 安裝的

2、在/etc/下建立my.cnf 新增內容如下：

[mysqld]
#log_bin
log-bin = mysql-bin #開啟binlog
binlog-format = ROW #選擇row模式
server_id = 1 #配置mysql replication需要定義，不能和canal的slaveId重複

3、重啟的時候最好是使用mysql.server restart 不然老是報更新錯誤

4、show variables like ‘%log_bin%’ 檢視開啟

+---------------------------------+
 
--------------------------------------+
| Variable_name                   | Value                                |
+---------------------------------+--------------------------------------+
| log_bin                         | ON                                   |
| log_bin_basename                | /usr/local/var/mysql/mysql-bin       |
| log_
 
bin_index                   | /usr/local/var/mysql/mysql-bin.index |
| log_bin_trust_function_creators | OFF                                  |
| log_bin_use_v1_row_events       | OFF                                  |
| sql_log_bin                     | ON                                   |
+---------------------------------+--------------------------------------+
 

5、檢視binlog日誌狀態

show master status 

6、重新整理binlog日誌檔案

flush logs #重新整理之後會新建一個新的Binlog日誌

7、清空日誌檔案

reset master

8、檢視binlog日誌檔案

mysqlbinlog mysql-bin.000002
