在配置文件 /etc/my.cnf 添加变量 log-bin：
log-bin=/var/lib/mysql/mybinlog/mysql-bin
重启数据库服务报错：
[root@htlwk0001host lib]# systemctl start mysqld.service
Job for mysqld.service failed because the control process exited with error code.
See "systemctl status mysqld.service" and "journalctl -xe" for details.
解决方案：
log-bin 和 server-id 要一起设置，才不会报错：
log-bin=/var/lib/mysql/mybinlog/mysql-bin
server-id=1
