      /etc/my.cnf

   2. Add the configuration

      #  Turn on binary log 
      server-id=1
      log-bin=/usr/local/mysql/data/mysql-bin

docker

1. The configuration is mapped to a local file , The local file configuration is as follows

   [mysqld]
   #binlog setting
   log-bin=/var/lib/mysql/mysql-bin
   server-id=123454
   binlog-format=ROW

1. restart mysql, Search found binlog It's not turned on

   docker restart mysql

2. It took a long time to find this hole on the Internet , Record the process

   First , see docker About my.cnf I found this sentence in my log ：

   mysqld: [Warning] World-writable config file '/etc/mysql/``my.cnf``' is ignored.

   Viewing on the Internet is caused by the permission of the configuration file https://blog.csdn.net/qilovehua/article/details/45508925, For details, please refer to this blog post

   Then enter docker Of mysql Container to check , Sure enough my.cnf The permissions for are 777

   Change it to 644

   chmod 644 my.cnf

   Restart again mysql Containers , Check it out binlog Successfully opened

   however , If you make any changes to the mapped configuration file later , He will be mapped again to /etc/mysql/my.cnf This file and the permissions are reset to 777, Need to modify again
