Mysql 主从同步之Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'问题解决

查看主日志号
 MariaDB [(none)]> Flush logs;  （这时主服务器会重新创建一个binlog文件；）
 MariaDB [(none)]> show master status;
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000003 |      385 |              |                  |

 在从中查看slave日志文件号show slave status\G
   File :mysql-bin.000005
发现是因为主从日志文件号不同而导致 
在从中stop slave;

MariaDB [(none)]> change master to master_log_file =‘dbmaster-bin.000005‘,master_log_pos=120; 

MariaDB [(none)]> flush privileges; 

MariaDB [(none)]> start slave; 

MariaDB [(none)]> show slave status\G
