开启 binlog
- 修改 /etc/mysql/my.cnf
(mac 本地的话，如果 /etc/mysql/my.cnf 或 /etc/my.cnf 没有， 把 ./Users/shicai.xsc/Downloads/5.7/my.cnf 拷贝到 /etc/my.cnf )
[mysqld]
log-bin=/mysql_binlog
#(必须有，不然报错，值随便设：https://blog.csdn.net/keketrtr/article/details/71209576)
server-id=1
expire-logs-days=1- 然后
sudo mkdir /mysql_binlog
sudo chown mysql:mysql /mysql_binlog
sudo chmod 770 /mysql_binlog
- 然后
service mysql restart （mac: sudo /usr/local/mysql/support-files/mysql.server start --log-error=/Users/shicai.xsc/log）
- 然后，验证
连上 mysql，执行：show binary logs;
