我有两个类似的设备，运行基于yoctokrogoth的嵌入式linux发行版，它们都有512MB内存。这些设备通过以太网连接。他们两个都有 MariaDB 10.1.30 跑步。
我想有一种可能性来建立某种主要的次要关系。所以每 INSERT, UPDATE or DELETE 在主设备上执行将在辅助设备上复制。
每隔n秒在辅助设备上转储数据库是不合适的。此外，我还尝试按此处所述配置复制https://www.lexiconn.com/blog/2014/04/how-to-set-up-selective-master-slave-replication-in-mysql/ 但它不起作用- mysqld 如果不在日志中写入任何错误，服务就不会启动。
我想知道是否有其他方法来执行这种复制？可能是一些软件方式（python2.7用于该设备上的系统服务）。
这是 my.cnf 文件：

# password                   = password

port                        = 3306
socket                      = /var/lib/mysql/mysql.sock

[mysqld_safe]
err-log                 = /var/log/mysql.err

[mysqld]
user                        = mysql
port                        = 3306
socket                  = /var/lib/mysql/mysql.sock
pid-file                    = /var/lib/mysql/mysqld.pid
log-error                   = /var/log/mysqld.err
basedir                     = /usr
datadir                     = /var/lib/mysql

Thanks in advance.
